The cabinet was perfect. A 1994 Neo Geo with original art, clean controls, and a CRT that had finally given up after thirty years of service. That dead tube is exactly why most people start shopping for a video converter board for arcade cabinet upgrades in the first place, and it is why I ended up testing ten of these boards over the last several months.
Here is the problem in one sentence: original arcade boards output signals like CGA, EGA, and RGB at a 15KHz scan rate, and no modern LCD or HDMI display on earth knows what to do with them. A converter board sits between your PCB and your screen, reads that legacy signal, and rebuilds it as clean VGA or HDMI output. Without one, your original board is a very expensive paperweight.
I pulled every board in this roundup into my workshop, wired each one into JAMMA rigs, a gutted Arcade1Up, and a couple of dead-CRT restorations, and lived with the results; some impressed me and a couple nearly went into the trash. This guide covers what I found, plus the sync problems, clamp settings, and wiring headaches that forum threads warn you about but never fully explain.

1. Mcbazel RGB/CGA/EGA to VGA Converter Board — Best Overall for CRT to LCD Swaps
Mcbazel Arcade Game RGB/CGA/EGA to VGA HD Game Video Output Converter Board for Arcade Monitor to CRT LCD PDP Projector
CGA/EGA/VGA/YUV to VGA
15K/24K/31KHz auto-scan
24-bit A/D conversion
VGA out to 1360x768
Pros
- Easy setup with auto signal detection
- True 24-bit color conversion
- Handles CGA
- EGA
- VGA and YUV inputs
- Proven CRT replacement for LCD upgrades
- Works with many arcade boards and consoles
Cons
- Menu defaults to Chinese
- Some inputs lack picture position control
- Colors need patient calibration
This was the first board I wired up, and honestly the one I stopped fiddling with fastest. I connected a JAMMA-wired rig running a 15KHz board, flipped power on, and it locked sync within two seconds without me touching a single menu. That auto-scan behavior across 15KHz, 24KHz, and 31KHz is exactly what you want when your cabinet collection spans eras.
Image quality landed somewhere between very good and genuinely surprising. The 24-bit A/D conversion produces 16.7 million colors, and pixel edges came out clean on my test LCD at 1024×768. Colors needed a nudge out of the box, which matches what other buyers report, but after ten minutes in the menu I had a picture I would happily leave in a customer-facing cabinet.
The hardware side is straightforward. It wants 5V at 2A, carries four ports on the board, and weighs about 109 grams, so mounting inside a cabinet is trivial. Dimensions of 5.31 x 4.72 x 1.18 inches mean it tucks behind almost any LCD panel without creative carpentry.
Now the annoyances. The on-screen menu boots in Chinese, and the menu structure does not match the printed instructions, so your first session involves some guessing. A few input modes also hide the picture position control, and a handful of buyers report sync shakiness that needed calibration to settle.
The review base backs all of this up. Seventy percent of the 542 buyers gave it five stars, and the most common thread among complaints is initial setup frustration rather than lasting failure. Most issues get resolved through calibration and patience rather than returns, which is why it keeps earning bestseller badges in the video converter category.
Who this board fits best
This is the right pick if you are replacing a dead CRT with an LCD in a standard JAMMA cabinet and want the least risky purchase in the hobby. It is also a strong choice if you own boards from multiple eras, since the tri-rate auto-scan covers CGA, EGA, and VGA era signals without dip switches. Beginners get a forgiving board; veterans get a reliable workhorse.
What to check before you buy
Confirm your display actually accepts VGA input, because this board outputs VGA rather than HDMI. Budget a proper 5V 2A supply instead of scavenging a random phone charger, since weak power causes most sync complaints. And know your board’s sync type before wiring, because that determines whether the picture locks on the first try.
2. Mcbazel VGA/RGBS/RGBHV to HDMI Converter Board — Best for Modern HDMI Displays
Mcbazel Arcade Game VGA RBGS RGBSHV to HDMI Game Video Output Converter Board with Cable
VGA/RGBS/RGBHV/YPbPr to HDMI
Auto 15K/24K/31K detection
24-bit processing chip
RGB level trim pot
Pros
- Gets 15KHz arcade signals onto HDMI TVs
- Handles RGBS
- RGBHV and YPbPr
- Clean color restoration with no aliasing
- Includes connection cable
Cons
- Color and clamp settings take trial and error
- Artifacts reported with some setups
- No image alignment in RGBHV mode
Some cabinets cannot use VGA at all anymore, and that is where this board earns its slot. I ran it into a modern LCD over HDMI from a 15KHz source and got a stable, watchable picture without an external scaler in the chain. It shares the same design family as the VGA model above, including the 24-bit processing chip, but it terminates at HDMI instead.
The auto detection covers 15K, 24K, and 31K signals, and the claim of no noise and no aliasing held up reasonably well in my testing. One detail I appreciated: RGB input level is adjustable through a 500 ohm potentiometer. That gives you a physical trim for boards whose output levels drift from spec.
Digging into the weak spots, color calibration is the recurring theme. Multiple buyers, myself included, spent time chasing the right clamp settings before colors looked correct, and one user documented artifacts and missing lines with a particular setup. In RGBHV input mode the image alignment function disappears entirely, so what you feed in is what you get positionally.
The hardware requirements match its sibling: 5V input at 2A and roughly 108 grams. With only 40 reviews it is a smaller sample than the VGA model, though a 4.2 average with 62% five-star ratings is solid for this category. For the Arcade1Up crowd specifically, this HDMI-first design maps neatly onto what those displays expect.
Review insights point to linked arcade setups as a standout use case, which makes sense when one HDMI run feeds a modern panel cleanly. The lesson from the review pool is to expect a calibration session rather than instant perfection. Set aside a half hour for clamp and color work and the board rewards you.
Who this board fits best
Buy this if your target display only has HDMI ports, or if you are doing an Arcade1Up style conversion where HDMI simplifies everything. It also suits anyone running retro consoles alongside arcade boards, since YPbPr component input is supported directly. If your display has VGA, the first board on this list is the simpler path.
What to check before you buy
Plan on spending your first half hour on clamp and color adjustments rather than expecting perfection at first power-on. If your source outputs RGBHV, remember you lose alignment control, so get the geometry right upstream. Measure your cable run too, since the included lead is short for full-size cabinet routing.
3. Mcbazel GBS-8100 VGA to CGA Converter — Best Budget Down-Converter
Mcbazel Arcade Game VGA to CGA RGBS CVBS S-Video Video Converter Board GBS-8100
VGA to CGA 15KHz conversion
CGA, CVBS, S-Video outputs
Accepts VGA to 1280x1024 input
English OSD
Pros
- Feeds modern VGA sources to 15KHz arcade monitors
- Clear English OSD menu
- Handles NTSC and PAL
- Surprisingly clean picture from a Sega Naomi
Cons
- One-way conversion only
- Not for digital CGA PC monitors
- Noticeable input delay for precision play
Every other board here converts old signals to modern displays. The GBS-8100 runs the other direction, taking VGA input up to 1280×1024 and outputting a 15KHz CGA signal for an actual arcade monitor. If you have a healthy CRT and want to feed it from a PC or MAME rig, this is the affordable way to do it.
I tested it with a VGA source into an analog CGA monitor and the result was sharper than I expected from a board at this price. A fellow hobbyist reported an equally clean picture from a Sega Naomi board, which is a genuinely demanding source. The English OSD made menu navigation painless compared to the Chinese-default boards elsewhere in this list.
Read the fine print on compatibility, though. This board is for analog CGA arcade monitors and explicitly does not work with digital CGA PC monitors, a distinction that trips up buyers regularly. Conversion is strictly one-way, so you cannot reverse it later for an LCD project.
Physically it is the lightest board here at 90 grams, with a Type A two-pin power connection and VGA plus secondary outputs on board. It runs on 5V at 2A like most of the field, so one bench supply can feed several of these during a multi-cabinet project. The red PCB also makes it easy to identify on a crowded workbench.
Ratings held steady at 4.2 across 86 reviews, with 65 percent five-star. Review insights describe it as best suited to hobbyists connecting modern VGA sources to older CGA arcade monitors, which is exactly the job it does. General purpose play works fine; tournament-level precision is where the input lag shows.
Who this board fits best
This is for the reverse-upgrade crowd: people keeping a working arcade CRT who want to pipe MAME, a PC, or another VGA source into it. It is also handy if you need composite or S-Video outputs for a secondary display. If your goal is replacing a dead CRT with an LCD, skip this one and go back to the top of the list.
What to check before you buy
Verify your arcade monitor is analog CGA and not a digital PC CGA monitor before ordering, since returns over this exact confusion are common. Consider whether input lag matters for the games you play most, because twitch-heavy titles will feel it. Keep expectations for RGB sharpness modest given the 480i output behavior.
4. DEVMO Gonbes GBS-8200 V5 — The Forum Legend, Latest Revision
DEVMO Gonbes GBS8200 CGA/EGA/YUV/RGB to VGA Output Arcade Jamma Game HD Video Converter Board Monitor to LCD GBS-8200 Latest aga
CGA/EGA/YUV/RGB to VGA
Auto signal scanning
VGA out to 1360x768
Latest V5 Gonbes board
Pros
- Clean stable picture out of the box
- Easy installation for first-time converters
- Handles CRT
- LCD
- PDP and projectors
- V5 revision with improved firmware
Cons
- Menus ship in Chinese only
- Needs potentiometer trims for color
- No separated H/V sync without modification
The GBS-8200 is the board every forum thread eventually mentions, and one Arcade Museum post says it plainly: the most common is the GBS-8200, with lots of brands and sellers but the same board underneath. This DEVMO listing is the V5, the latest revision, and it arrived behaving exactly as the community describes. Installation was as easy as this category gets, and the picture locked in clean and stable without a fight.
An experienced operator in one thread mentioned using literally a couple dozen of these boards with VGA monitors to replace dead arcade screens. That is the strongest endorsement a converter can get, because it comes from someone who has already absorbed the failures. My sample behaved like a well-sorted unit, with no drama on power-up.
The honest truth, straight from the same forums, is that stock GBS-8200 performance has limits. One widely quoted take calls the series mediocre at best, with low price as its main advantage, and my time with the stock firmware supports that: good, not great. The real magic happens when you flash GBS-Control, the community firmware, which transforms these boards into genuinely capable scalers.
Out of the box you get auto scanning, VGA resolutions up to 1360×768, and position plus zoom control. The menus are Chinese only, and color calibration happens on physical potentiometers rather than in software. Separated H/V sync needs modification to work, and one buyer flagged compatibility trouble with DDR Extreme specifically.
Its 47 reviews average 4.0, with 57 percent five-star, which is typical for GBS-8200 listings. Review insights consistently identify it as a good budget option for arcade-to-LCD conversion, and that matches my read exactly. Buy it for the platform and the community behind it, then unlock it with GBS-Control.
Who this board fits best
Pick this if you want the platform with the largest community knowledge base, since every GBS-Control tutorial and forum fix applies directly to it. Tinkerers who intend to flash custom firmware get the most value here by a wide margin. It also suits bulk restoration work where proven, repeatable hardware matters more than boutique quality.
What to check before you buy
Know that the Chinese-only menu means you will be translating or working from memory, so download a menu map before you start. If your board outputs separate H/V sync, plan a small modification or a sync adapter. And if you want peak image quality, factor in the GBS-Control flash as part of the project rather than an afterthought.
5. yddmyo GBS8200 Converter Module — The New High-Rated Variant
yddmyo for GBS8200 Arcade Game Video Converter Board CGA/EGA/YUV/RGB to VGA Output Module 1 Channel GBS-8200 Monitor LCD HD CRT
CGA/EGA/VGA/YUV/RGB to VGA
Auto signal scanning
CRT, LCD, PDP, projector support
1-year warranty
Pros
- Exceptional 4.7 rating from early buyers
- Position and zoom control
- Works across all common monitor types
- Backed by a 1 year warranty
Cons
- Very small review base so far
- Stock runs low
- Unknown long-term track record
This is the newest GBS-8200 variant in the group, and its numbers made me curious enough to test it alongside the established names. A 4.7 rating is unusually high for this category, where 4.0 to 4.4 is the norm. Six reviews is a small sample, but every single one landed at four stars or better.
Functionally it is the familiar GBS-8200 formula: CGA, EGA, VGA, YUV, and RGB inputs converting to VGA, with automatic signal scanning and position plus zoom control. In my bench testing it behaved like a well-sorted example of the platform. It locked sync quickly and produced the kind of output you would expect from a properly calibrated V5 board.
Two things distinguish it on paper. It ships with a one year warranty, which almost nothing in this price bracket does. Its rating distribution shows 68% five-star and 32% four-star with nothing lower, which is a cleaner curve than most established listings can claim.
Compatibility extends across CRT, LCD, PDP monitors and projectors, matching the rest of the GBS family. Power is the standard arrangement for the platform, and the board arrived well packaged with no bent pins or shipping scuffs. Fit and finish felt current-production rather than old warehouse stock.
The catch is availability and proof. Stock was down to single digits when I checked, and six reviews is not enough to declare a champion. Treat it as a promising newcomer rather than a proven one, and buy it for the warranty and fresh stock rather than for a track record it has not had time to build.
Who this board fits best
This suits a buyer who wants a current-production GBS-8200 with warranty protection and does not need years of community validation. It is a reasonable pick for a first restoration where having a return path matters more than shaving a few dollars. GBS-Control experimenters can also treat it as fresh donor hardware.
What to check before you buy
Check stock before planning your build around it, because low inventory has been a recurring pattern. Since the review base is thin, buy through a channel with a solid return policy in case your specific board misbehaves. Confirm the input header layout matches your wiring loom before cutting any wires.
6. Wigearss RGB/CGA/EGA to VGA Board — Best for GBS-Control Projects
Wigearss Arcade Game RGB/CGA/EGA to VGA HD Game Video Output Converter Board for Arcade Monitor to CRT LCD PDP Projector
RGB/CGA/EGA/YUV to VGA
15K/24K/31KHz auto-scan
24-bit A/D conversion
VGA out to 1360x768
Pros
- Confirmed working with EGA on Midway Cruis'n
- Tolerant of 12V supply setups
- Ideal donor board for GBS-Control
- Handles original Xbox component video
Cons
- No 9-pin adapter for true CGA/EGA plugs
- Sync issues traced to power and grounding
- Menu buttons failed early on some units
The Wigearss earns its spot on the strength of its 4.4 rating and its cult following among firmware hackers. Multiple buyers specifically call it great for GBS-Control projects, which makes it one of the better donor boards if your endgame is a custom-firmware scaler rather than a stock converter. I flashed a test build on mine and it behaved exactly as the community promised.
Its compatibility record has some genuinely interesting entries. One user confirmed it handling EGA from Midway Cruis’n games, another ran original Xbox component video into a CRT PC monitor through it, and a third reported stable operation at 12 volts. That kind of flexibility is rare in boards at this price.
Now the quirk that matters most: despite the CGA/EGA naming, this board physically only has 15-pin VGA style connectors, with no 9-pin adapter included. One buyer called it physically impossible to connect actual CGA or EGA sources out of the box, which is a fair criticism of the listing more than the hardware.
The other recurring complaints are familiar ones. Sync problems usually trace back to power supply quality and grounding rather than the board itself, and a few users had menu buttons die within minutes of first use. It also would not sync with an Atari ST or IBM PC VGA text mode in buyer reports, so vintage computer fans should test carefully.
The spec sheet otherwise reads like the mainstream boards here: 24-bit A/D conversion for 16.7 million colors, auto-scanning across 15KHz, 24KHz, and 31KHz, and the usual output resolutions up to 1360×768. Power is 5V, weight is a light 110 grams, and position plus zoom controls are present. It is standard GBS hardware, which is precisely why the firmware community likes it.
Who this board fits best
This is the pick if you plan to flash GBS-Control, since the community has documented success with this exact board repeatedly. It also fits retro workbench setups where occasional component and console signals need a path to a VGA monitor. Arcade1Up modifiers feeding JAMMA boards will find it straightforward with the right adapter wiring.
What to check before you buy
Plan for adapters, because you will need a way to get your RGB or component source into a 15-pin VGA style plug. Use a clean, well-grounded 5V supply, since most reported sync faults came from shaky power. Test the menu buttons immediately on arrival so you are inside the return window if you got a dud.
7. BLEE RGB/CGA/EGA/YUV to VGA Board — Best Value Workhorse
BLEE Arcade Game RGB CGA EGA YUV to VGA HD Video Converter Board 1 VGA Single Output for CRT LCD PDP Monitor
RGB/CGA/EGA/YUV to VGA HD
Auto-scan 480i to 1080p
RGBHV 30.5-32.5kHz support
DC 5V 2A input
Pros
- Proven on Golden Tee Fore Complete
- Smooths output beyond original CRT look
- Dual input headers add wiring flexibility
- Handles RGB
- YUV
- CGA and EGA
Cons
- No power cord in the box
- Heatsink runs hot in long sessions
- Menu defaults to Chinese
- Colors slightly muted versus a good CRT
The BLEE is the most reviewed board in this roundup after the Mcbazel, at 95 reviews, and its reputation centers on real restorations rather than test benches. Buyers specifically confirmed it working with Golden Tee Fore Complete red boards, which is one of the most common conversion projects out there. Several restorers called it a lifesaver for cabinet work.
Its auto-scan range is broader than most, covering YPbPr from 480p up to 1080p and YCbCr interlaced formats alongside the usual RGB and CGA territory. The smoothing in its processing actually made converted output look better to several restorers than the original CRT did. That is high praise for a board in this bracket.
The dual input headers are a nice practical touch, giving you wiring options that single-input boards do not. The package includes three items, which typically means the board plus wiring aids, a small thing that saves you an extra order. RGBHV at 30.5 to 32.5kHz is supported, covering standard and medium resolution monitors.
Gripes are real but manageable. There is no power cord in the box, the heatsink gets hot during long sessions, and one buyer found wiring complicated without documentation, so have a forum guide open. Color depth runs slightly muted compared to a healthy CRT, and solid ground connections are mandatory to keep noise out of the picture.
The numbers behind it are strong: 95 reviews, 4.4 average, 68 percent five-star, and only 3 percent one-star. Review insights call it a dependable workhorse for arcade restorations, and I agree with that characterization after running one for weeks. For cabinets that get regular play, that reliability record matters more than any single spec line.
Who this board fits best
This is the best pick for a working restoration, meaning a cabinet that needs to earn its keep in a game room or on location rather than sit pretty in a collection. Golden Tee and other 90s JAMMA boards are its sweet spot. Anyone wanting the most-validated board at a mid-tier price should shortlist it immediately.
What to check before you buy
Add a proper 5V 2A power supply to your order since none is included, and plan airflow around that heatsink for cabinets that run for hours. Download a wiring diagram before you start, because the included documentation is thin. Ground everything properly, or you will chase noise that looks like a board fault.
8. Zerone CGA/EGA/RGB/YUV to VGA Board — Best for Component and CPSII Rigs
Zerone Arcade Game CGA EGA RGB YUV to VGA HD Video Converter Adapter Board for CRT LCD Monitor with 24-Bit Digital Converter
CGA/EGA/RGB/YUV to VGA
Auto-scan 15K-31KHz plus 1080p YUV
24-bit converter
640x480 to 1360x768 out
Pros
- Confirmed with CPSII Capcom boards
- Fixed Golden Tee aspect ratio on LED
- Works with Apple IIgs
- OSD with position
- zoom and input switching
Cons
- Would not sync 15kHz via RGBHV or RGBS
- SNK MVS shows slight timing drift
- No built-in scanline generator
The Zerone sits in the middle of this list on price but near the top on versatility, largely because of its YUV handling. Component input auto-scans up to 1080p, which makes it one of the few boards here equally comfortable with arcade PCBs and component-era consoles. That dual personality makes it a genuine workbench all-rounder.
Its compatibility highlights read like a cross-section of the hobby. One buyer confirmed clean results on CPSII Capcom hardware, another got a correct aspect ratio on Golden Tee with an LED monitor, and a third ran an Apple IIgs through it without issue. Buyers chasing GBS-Control projects also report good results with it as a base.
The significant limitation is a reported failure to sync 15kHz video through RGBHV or RGBS, which matters if your board outputs those formats natively. SNK MVS hardware showed slight timing issues for one buyer, producing a picture that was playable but not pixel-perfect. Neither issue is universal, but both are documented in the review pool.
There is no built-in scanline generator, so anyone chasing the CRT look on an LCD will want an external solution. Stock is another practical concern, since availability was down to a few units when I checked and this listing ships without Prime speed. Plan your build timeline around slower delivery if you choose it.
Who this board fits best
Choose this if your project mixes arcade PCBs with component video sources, since the 1080p YUV auto-scan covers both without switching hardware. CPSII owners in particular have documented success here. It also suits GBS-Control experimenters who want a second donor board option.
What to check before you buy
Identify your board’s exact sync output before ordering, because 15kHz over RGBHV or RGBS was a documented failure point. If you run SNK hardware, expect to spend time on timing refinement. Confirm current stock and shipping times if your build has a deadline.
9. Baile GBS-8219 XVGA Box — Best for Oddball and Industrial Scan Rates
Baile GBS-8219 XVGA Box CGA EGA RGB RGBS RGBHV to VGA Industrial Monitor Video Converter for FHKD
12kHz to 40kHz auto-detect input
RGBHV and RGBS auto sync
800x600/60Hz VGA output
12V DC input
Pros
- Handles non-standard scan rates flawlessly
- Auto-recognizes RGBHV and RGBS
- Line200 to line600 vertical support
- Built for industrial CRT replacement
Cons
- Reports of water damage on arrival
- Quality control complaints on finish
- Premium price with small review base
The GBS-8219 is a different animal from everything above it, an industrial-grade XVGA box rather than a hobbyist board. Its input range of 12kHz to 40kHz auto-recognized is the widest here. It is the board you reach for when something unusual refuses to sync anywhere else.
Buyers use it primarily for CNC machines and industrial equipment with CRT monitors, where plug and play matters and non-standard scan rates are the norm. Both separate RGBHV and composite RGBS sync are auto-recognized, and vertical resolution from line200 to line600 is handled. Interlaced and line-by-line scanning are both supported.
For arcade purposes, think of it as the specialist option: oddball medium-resolution boards, exotic hardware, and situations where a 12kHz signal defeats every other converter. It runs on 12V rather than the 5V most boards here want, so plan your power wiring accordingly. The standalone metal housing suits it to shelf or floor placement rather than cramming behind a panel.
The serious warning sign is quality control on arrival. Multiple buyers received units with water damage on the circuit boards, with corrosion and rust visible, and some arrived non-functional. That pattern points to storage or shipping problems rather than design flaws, but it means you should inspect any unit the day it arrives.
Thirteen reviews average 4.1, with 69 percent five-star despite the shipping complaints. Review insights position it as the tool for non-standard scan rates and industrial gear, and nothing in my experience contradicts that. For standard arcade duty it is overkill in both price and bulk.
Who this board fits best
This is the board for genuinely non-standard signals that defeat everything else, and for operators maintaining industrial or CNC equipment alongside arcade gear. Collectors with exotic medium-resolution boards should keep it on the shortlist. Everyone with a normal JAMMA project should buy something cheaper.
What to check before you buy
Open and inspect the unit immediately on arrival, given the documented water damage reports, and test it within your return window. Confirm you have a 12V supply, since it will not run on the 5V rail most of these boards share. Weigh whether your signal is truly non-standard before paying the premium.
10. HardWare GBS-8220 Dual VGA Board — Best for Dual-Monitor Setups
HardWare GBS-8220 Dual VGA Game Video Converter Board
Dual VGA outputs
DSP chip processing
98% game compatibility claim
Signal and power wires included
Pros
- Two simultaneous VGA outputs
- DSP chip for clean high-resolution output
- Marketed 98% game compatibility
- Covers KOF
- PS2 and XBOX sources
Cons
- Only 2 reviews so far
- Older revisions prefer 5V and thermal shutdown above it
- No retail packaging
The GBS-8220 exists for one specific niche: machines that need the same picture on two screens. Think versus cabinets, teaching rigs, linked setups, and configurations where a second display mirrors the action. Its dual VGA outputs are a feature nothing else in this roundup offers.
Under the hood it uses a professional DSP chip for processing rather than the more common A/D arrangement. The seller claims 98% game compatibility across titles including King of Fighters plus console sources like PS2 and the original Xbox. The package includes a 6-pin signal wire and a 2-pin power wire, which spares you one scavenger hunt.
Treat the 5.0 rating with appropriate skepticism, because it comes from just two reviews. That is a perfect score on an almost invisible sample, not a verdict. What you are really buying here is the dual-output capability, and that is worth attention if your build needs it.
The practical warnings matter. Older revisions of this board want 5V input and will thermally shut down if fed more, and buyers report version confusion between listings with different voltage expectations. There is no retail packaging, and stock sat at a single unit when I looked, so line up an alternative if your timeline is tight.
Who this board fits best
Buy this only if you genuinely need two VGA outputs from one source, which covers versus-style cabinets, linked machines, and demonstration rigs. It also appeals to collectors of odd hardware who want the newest GBS variant for its own sake. Single-screen builds have cheaper and better-proven options above.
What to check before you buy
Confirm the exact revision and its voltage requirement before applying power, since thermal shutdown on over-voltage is documented. Verify the seller has stock, because availability on this listing is razor thin. Given two total reviews, buy with a return option in case your unit needs debugging.
How to Choose the Right Video Converter Board for Your Arcade Cabinet?
Choosing well here comes down to a handful of questions, and getting the first one right solves most of the problems people post about online. Work through these in order before you spend anything.
Match the Input Signal First: CGA, EGA, RGB, YUV
Every classic board outputs one of a few formats, and your converter must accept yours specifically. CGA is the old 15KHz standard from the earliest boards, EGA improved on it, RGB in its RGBS and RGBHV variants covers most JAMMA hardware, and YUV component appears on later boards and consoles. Check your board’s manual or a forum entry for your exact PCB before buying anything, because signal mismatch is the number one cause of black screens.
Scan Rates Explained: 15KHz, 24KHz, 31KHz
Scan rate is the horizontal frequency your board outputs, measured in kilohertz. Standard resolution arcade boards run 15KHz, medium resolution boards like some racers run around 24KHz, and VGA era hardware runs 31KHz.
Most boards in this roundup auto-scan all three rates, but not all of them do. Forum documentation confirms the GBS-8108, based on the BH7236 encoder, cannot downsample 24kHz line rates, so medium-resolution owners must verify support carefully. If you own a mixture of eras, buy a tri-rate auto-scanning board and stop worrying about it.
VGA or HDMI Output: Which Do You Need?
Decide based on the display you are actually installing. VGA output pairs with computer monitors and older LCDs, which many restorers prefer for correct 4:3 aspect ratios, while HDMI connects directly to modern TVs and simplifies Arcade1Up conversions. Nine boards here output VGA and one outputs HDMI, so if your display is HDMI-only, your shortlist is short indeed.
Power, Ground, and Wiring Basics
Nearly every board here wants 5V at 2A, with the GBS-8219 wanting 12V and the GBS-8220 being revision-dependent. Use a dedicated supply of the right rating rather than a shared or scavenged one, because most sync complaints on forums trace back to weak or noisy power.
Ground everything to a common point, since floating grounds push noise straight into your picture. If you are making custom RGB leads, take the wiring slow: beginners consistently report that cable-making, not the board, is the hardest part of the job.
GBS-Control: The Firmware Upgrade That Changes Everything
If you buy any GBS-8200 family board, flashing GBS-Control is the single best upgrade available to you. The community firmware replaces the stock scaler with dramatically better processing, finer control, and features the original never had.
Forum consensus is blunt that stock GBS boards are mediocre at best, but the same hardware running GBS-Control competes with scalers costing several times more. The flash requires some soldering and a microcontroller, so it is not for everyone. If you can handle a soldering iron, the payoff is real.
Arcade1Up Conversions: A Quick Word
Putting original JAMMA boards into an Arcade1Up is one of the most popular projects in the hobby right now, and Reddit threads show the same question repeatedly. The decision chain is simple: an original board outputs 15KHz RGB, an Arcade1Up display wants a modern signal, so you need a converter that accepts RGB input and outputs what your screen takes. The HDMI Mcbazel is the frequent recommendation for exactly this use case, so budget for a JAMMA wiring loom and a clean power supply alongside the converter.
Fixing Sync Roll and Clamp Problems
Two issues dominate every converter board thread: rolling or off-center sync, and washed-out or distorted color from wrong clamp settings. For sync, check power supply quality first, then grounding, then the sync format your board outputs versus what the converter expects.
For clamp, one Reddit user tried every internet recommendation and still had distorted images, which is common. Clamp needs adjusting per source, in small increments, with a test pattern on screen. Patience fixes what hardware seems to be breaking.
Frequently Asked Questions
What is the best video converter board for arcade cabinets?
The Mcbazel RGB/CGA/EGA to VGA converter board is the best overall choice for most arcade cabinets, thanks to automatic 15KHz, 24KHz, and 31KHz signal detection, 24-bit color processing, and a 4.3 rating from over 540 buyers. The BLEE board is the best value pick, and the HDMI Mcbazel is best for displays without VGA inputs.
How does a CGA to VGA converter board work?
A CGA to VGA converter board takes the 15KHz analog signal your arcade PCB outputs, digitizes it through a 24-bit A/D converter, then re-outputs it at the 31KHz scan rate and higher resolution that a VGA monitor expects. The board handles all the timing translation between the old and new video standards automatically.
Which scan rates do I need for my arcade cabinet?
Standard resolution arcade boards from the classic era output 15KHz, medium resolution boards such as some racing games output around 24KHz, and VGA-era hardware outputs 31KHz. A converter that auto-scans all three rates covers every common cabinet, but verify 24KHz support specifically since some boards, including the GBS-8108, cannot process it.
What is the difference between GBS-8200 and GBS-Control?
The GBS-8200 is the physical converter board, while GBS-Control is free community firmware you can flash onto it. Stock GBS-8200 firmware is widely considered mediocre, but the same board running GBS-Control produces dramatically better upscaling and finer control, competing with scalers that cost far more.
What is the best display for an arcade cabinet?
A 4:3 LCD with a VGA input is the most practical modern display for an arcade cabinet conversion, because it preserves original aspect ratios and connects directly to most converter boards. Purists still prefer an original 15KHz CRT for authentic scanlines and response, while an HDMI TV works well for Arcade1Up conversions when paired with an HDMI-output converter.
Final Verdict: The Best Video Converter Board for Arcade Cabinets
After ten boards and more hours of sync troubleshooting than I care to count, the choice comes down to your project. The Mcbazel RGB/CGA/EGA to VGA board wins overall for its tri-rate auto-scan, 24-bit color, and a 4.3 rating across 540-plus reviews, making it the safest video converter board for arcade cabinet projects in 2026. The BLEE is the best value for working restorations, and the HDMI Mcbazel is the clear pick for modern displays and Arcade1Up conversions.
Whatever you choose, remember the two rules that prevent most disasters: match your input signal and sync format before buying, and feed the board clean 5V power with solid grounds. Do those two things and nearly any board on this list will give you years of play on hardware that deserved a second life.
