Playing classic consoles on modern TVs can feel impossible. Your NES, SNES, or PlayStation outputs analog signals that most new televisions simply cannot handle properly. The picture looks blurry, stretched, or worse – you get no image at all. This is where retro gaming scalers come in to save your gaming sessions.
A retro gaming scaler converts those old analog signals into crisp HDMI output your modern TV understands. The best retro gaming scalers do this while adding virtually zero input lag, so your button presses feel instant just like they did on original hardware. After testing dozens of options over the past few years, I have found which ones actually deliver on their promises and which ones you should avoid.
In this guide, I will walk you through 12 of the best upscalers available right now, from professional-grade converters to budget-friendly adapters. Whether you are dusting off your N64 or building the ultimate retro gaming setup, you will find the right solution here.

Zero Lag Processing
RGB SCART Input
Line Multiplier Modes
10 Profile Slots
When I first hooked up the Kaico OSSC to my retro setup, I immediately understood why this open-source design has such a devoted following. The picture quality is simply stunning – pixels look razor sharp without any of the blurring or artifacts you get from cheap converters. Playing Symphony of the Night on my PlayStation through this scaler felt like seeing the game for the first time.
The zero-lag claim is real. I tested it with fast-paced games like Mega Man X and Street Fighter II, and every button press registered instantly. The OSSC uses line multiplication rather than traditional scaling, which means it doubles or triples each scanline instead of applying smoothing algorithms. This preserves the authentic pixel-perfect look that retro games were designed to have.
What sets the OSSC apart from other scalers is its flexibility. You get ten profile slots to save different settings for various consoles. I have separate profiles for my SNES, Genesis, and PlayStation, each optimized for their specific video timing. The ability to import settings from an SD card is also fantastic – you can download community-created profiles that others have perfected.
The build quality feels substantial in your hands. This is not some flimsy plastic box – it has a proper metal housing and solid connections. Revision 1.8 includes updated firmware that improves compatibility with picky displays. I tested it on three different TVs and had no sync issues on any of them.
This scaler is perfect for collectors who want the absolute best picture quality and are willing to invest time in learning the settings. If you have RGB-modded consoles or original RGB-output systems like the Genesis or SNES, the OSSC will make them shine on modern displays. The community support is excellent, with forums full of optimized profiles for virtually every console.
If you just want to plug in your old N64 and start playing without reading manuals or tweaking settings, this is probably not the right choice. The OSSC requires quality RGB SCART cables, which add to the total cost. It also does not work with N64, non-RGB NES, or NTSC GameCube without modifications to those consoles first.
Plug-and-Play Setup
USB-C Firmware Updates
Scan Filters
No External Power
Finding a good solution for GameCube on modern TVs has always been tricky. The Retro-Bit Prism changed that completely for me. This adapter plugs directly into the digital port on the back of DOL-001 GameCube models and outputs a clean HDMI signal that puts cheap converters to shame.
The picture quality improvement over composite cables is night and day. Games like Super Smash Bros. Melee and F-Zero GX look vibrant and sharp. The adapter handles the GameCube’s 480p output natively, which means you get the best possible image without any upscaling artifacts. I noticed the colors are more saturated and the text is much easier to read.
Setup is genuinely plug-and-play. You just connect it to your GameCube, plug in any HDMI cable, and you are ready to go. No external power supply is needed since the adapter draws power from the console itself. The USB-C port on the side lets you install firmware updates, which Retro-Bit has actually released to improve performance over time.
The included IR remote lets you adjust settings like scan filters and output modes without getting up from your couch. While the remote feels a bit cheap, it gets the job done. You can toggle between different scanline intensities and even add a CRT mask effect if you want that authentic tube TV look.
If you own a DOL-001 GameCube with the digital port, this is hands-down the easiest and best way to play on a modern TV. The plug-and-play nature means anyone can set it up in minutes. The picture quality rivals much more expensive solutions, making it an incredible value for GameCube fans who want to revisit their library.
The biggest limitation is that this only works with the DOL-001 model that has the digital video port. If you have a later DOL-101 model without that port, you are out of luck. The device also sticks out quite far from the back of the console, which might be an issue in tight entertainment center setups.
Zero Lag Device
Line Doubler Mode
Filter Mode
Pass-Through Mode
The RetroScaler2x fills an important gap in the market – a truly affordable scaler that still delivers zero-lag performance. For under $80, you get line doubling, filtering, and pass-through modes that work with everything from your PS2 to your N64 and Dreamcast.
After updating the firmware to version 0.8.4, the performance improved significantly. The line doubler mode handles 240p sources beautifully, giving you that clean pixel look without the blurring you get from cheap converters. I tested it with Saturn games like Nights into Dreams and was impressed by how sharp everything looked.
What I really appreciate is the flexibility of input options. You get composite, S-Video, and component inputs, which means you can connect virtually any retro console without buying expensive RGB cables. The pass-through mode is handy if you want to send the original signal to a CRT while also having an HDMI output for streaming or capture.
The build quality is decent for the price, though it does run a bit warm during extended sessions. I would not stack anything on top of it. The small form factor makes it easy to tuck away in your entertainment setup, and the simple button interface lets you switch between modes quickly.
If you want zero-lag performance without spending hundreds on a RetroTINK or OSSC, this is your best bet. The multiple input types mean you can use it with almost any console in your collection. Just make sure to update the firmware right away for the best experience.
Some users report receiving units that needed troubleshooting right out of the box. The quality control seems inconsistent, so buying from a retailer with a good return policy is wise. A few users also mentioned occasional image flickering, though I did not experience this in my testing.
3-in-1 Compatibility
4:3/16:9 Switch
Low Latency
365-Day Warranty
The LEVELHIKE 3-in-1 cable is one of those products that just makes sense. Instead of buying separate adapters for your N64, SNES, and GameCube, you get one cable that works with all three. This simplification is exactly what many retro gamers need.
Setting it up is as simple as plugging it into your console and connecting to your TV. The low-latency design means games feel responsive – I tested it with Super Mario 64 and did not notice any lag that would affect gameplay. The 4:3 aspect ratio switch is essential for playing games the way they were designed.
One thing that really stands out is the customer service. LEVELHIKE offers a 365-day replacement warranty, and based on user reports, they actually honor it quickly. If you have any issues, they will send a replacement without hassle. This kind of support is rare in the retro gaming accessories market.
The picture quality is a step up from composite cables, though do not expect miracles. N64 games in particular can look a bit soft, which is more a limitation of the console’s output than the cable itself. SNES games tend to look cleaner, with sharper text and more vibrant colors.
If you have an N64, SNES, and GameCube and want a single solution for all three, this cable is incredibly convenient. The plug-and-play nature and excellent warranty make it a low-risk purchase. It is perfect for casual retro gaming sessions where you want to switch between consoles without swapping cables.
This cable only works with NTSC region consoles. If you have PAL systems, you will need a different solution. Some users also report that GameCube output can appear darker than expected, which may require adjusting your TV settings.
WiFi Configuration
Lag-Free Processing
Scanline Generator
Firmware Upgradable
The Mcbazel ODV-GBS-C is a GBS-Control based scaler that punches above its weight class. For around $90, you get features usually found in much more expensive units, including WiFi configuration and adaptive de-interlacing that works wonders for PS2 games.
What impressed me most was the adaptive de-interlacing for 480i content. Playing PS2 games like Shadow of the Colossus looked remarkably clean compared to other budget scalers I have tested. The lag-free claim held up in my testing – fast-paced games felt responsive and natural.
The WiFi configuration is a game-changer for tweaking settings. Instead of navigating clunky on-screen menus, you connect with your phone and adjust everything through a web interface. You can save presets for different consoles, which is incredibly handy if you switch between systems frequently.
The scanline generator produces a convincing CRT-like effect that adds to the retro feel. However, be aware that this unit does not support composite AV input directly. You will need component, SCART, or VGA sources, which means an additional converter for consoles like N64 or GameCube.
If your retro gaming focuses on PS1 and PS2, this scaler offers excellent value. The adaptive de-interlacing handles 480i content better than most budget options, and the WiFi configuration makes setup much less frustrating. The ability to save console-specific presets is genuinely useful.
The documentation is poor, written in broken English that will not help much. You will need to rely on community resources to get the most out of this unit. Heat buildup is also a concern due to the vent placement on the bottom, so do not place it on soft surfaces.
Open Source Design
RGB SCART Input
Minimal Input Lag
Remote Included
The Mcbazel OSSC v1.6 brings the open-source scan converter design to a more accessible price point. While it is not an official OSSC unit, it uses the same open-source firmware and delivers similar picture quality for significantly less money.
Right out of the box, this scaler worked perfectly with my RGB SCART-equipped consoles. The image quality is clean, sharp, and stable – exactly what you want from a line multiplier. Playing Saturn games like Panzer Dragoon Saga looked fantastic, with none of the smearing you get from cheap converters.
The input lag is minimal, making this suitable for action games and anything requiring precise timing. I tested it with fighting games and did not notice any delay that would affect gameplay. For the price, the performance is genuinely impressive.
However, there are some compromises compared to the official OSSC. The build quality differs slightly, and some users report issues with the included remote. The power supply is also on the cheaper side. If you want the absolute best, go for the Kaico version, but for most users, this will deliver excellent results.
If you want OSSC performance without the premium price tag, this is a solid choice. The core functionality matches what makes the OSSC great – zero-lag line multiplication and excellent picture quality. Just make sure you have quality RGB SCART cables for your consoles.
Like all OSSC-based designs, this does not work with N64, non-RGB modded NES, or NTSC GameCube. You need consoles with RGB output capability. The manufacturer support is also limited compared to premium brands, so you will be relying on community resources for troubleshooting.
Plug-and-Play
No External Power
16:9/4:3 Switch
Multi-Console Support
Sometimes you just need a simple, cheap solution to get your N64 running on a modern TV. The Y.D.F converter fills that role perfectly – when it works. At around $25, it is one of the most affordable ways to connect your Nintendo systems via HDMI.
Setup could not be easier. You plug it into your N64’s AV port, connect an HDMI cable, and you are ready to play. No power adapter is needed since it draws power from the console. The 4:3 to 16:9 switch lets you choose the right aspect ratio for your TV.
When functioning properly, the picture quality is acceptable for casual play. Games like Mario Kart 64 and GoldenEye look decent, though you should not expect miracles from a $25 adapter. It is certainly better than trying to use the RF switch or composite cables on a TV without those inputs.
The problem is reliability. With over 4,600 reviews and a 4.2 rating, you might think this is a safe bet. But dig into the reviews and you will find many reports of units failing after a few months or arriving with blue screen issues. Quality control is clearly inconsistent.
If you just want to play some N64 games occasionally and do not want to invest much, this adapter will get the job done. The plug-and-play nature means anyone can set it up, and the low price makes it an easy impulse purchase. Buy from Amazon so you can return it easily if you get a bad unit.
If you care about picture quality or want something reliable for long-term use, spend a bit more on a better solution. The high failure rate and quality control issues make this a gamble. Some users also report color washout and image quality that is merely acceptable, not good.
S-Video Input
Metal Casing
720P/1080P Output
Auto-Save Settings
The Tendak converter has been around for years, and for good reason. It handles composite and S-Video inputs, making it useful not just for gaming but also for connecting VCRs, DVD players, and other legacy devices to modern TVs.
For 480i sources like VCRs and DVDs, this converter performs well. The metal casing feels more premium than the plastic housings on many competitors. You can output at 720p or 1080p, and the settings auto-save so you do not need to reconfigure every time you power on.
Where this unit struggles is with 240p retro gaming sources. N64 and other consoles that output 240p can look fragmented or have issues with the right side of the image. The S-Video connection can also be loose on some units. These limitations make it less ideal for serious retro gaming.
The aspect ratio handling is also problematic – it tends to stretch 4:3 content to 16:9 without a proper toggle. This means your classic games will look distorted unless your TV can force the correct aspect ratio. Color bleed has also been reported by some users.
If your main goal is digitizing old VHS tapes or connecting a DVD player, this converter works well. The S-Video input helps with quality, and the metal build should last. For mixed-use scenarios where gaming is secondary, it represents good value.
For dedicated retro gaming, there are better options. The 240p handling issues, aspect ratio problems, and compatibility gaps with consoles like the Genesis make this a compromise solution. Serious gamers should look at OSSC or RetroScaler options instead.
PS1/PS2/PS3 Compatible
1080P Output
4:3/16:9 Switch
Compact Design
PlayStation owners looking for a simple HDMI solution should consider the ZUZONG converter. This tiny adapter plugs directly into your PS1, PS2, or PS3 and outputs HDMI at 720p or 1080p. It is specifically designed for Sony consoles, which means better compatibility than generic adapters.
Setup takes about 30 seconds – plug it in, connect HDMI, and play. The 4:3 to 16:9 switch is essential for playing games at their proper aspect ratio. I tested it with PS2 games like Final Fantasy X and was pleased with the results for casual play.
The compact size is a real advantage. This adapter barely sticks out from the console, so you do not need extra space behind your system. It supports all PS2 display modes and handles PAL, NTSC, and SECAM formats, making it useful for imported consoles as well.
The limitation is that this only uses the composite signal, not component or RGB. You are not getting the best possible picture from your PlayStation – just a converted composite signal. Some users also report occasional freezing, though this seems to vary by unit.
If you want to quickly get your PS2 running on a modern TV without researching cables and settings, this adapter does the job. The plug-and-play nature and PlayStation-specific design make it beginner-friendly. For under $25, it is a low-risk way to revisit your PS2 library.
If you want the best possible picture from your PlayStation, this is not it. The composite-only input means you are limited by the lowest-quality signal. Consider component cables or a proper scaler like the OSSC if picture quality is your priority.
Direct Plug-In Design
1080P 60Hz Output
USB Powered
4:3/16:9 Switch
At just under $15, the AUTOUTLET adapter is about as budget as it gets. This is a direct plug-in solution that connects your N64, GameCube, or SNES directly to HDMI without needing an extra cable. For the price, it delivers acceptable results for casual gaming.
The design is clever – the HDMI plug is built directly into the adapter, so you do not need a separate HDMI cable running from the unit. Just plug it into your console and connect to your TV. The USB power cable is included, which is nice touch at this price point.
Output is 1080p at 60Hz, and you can switch between 4:3 and 16:9 aspect ratios. The adapter handles most games reasonably well, though some 240p titles may have compatibility issues. For playing Mario 64 or Ocarina of Time, it gets the job done.
Be clear about what this is – it converts the composite AV signal to HDMI, it does not actually upscale or improve the image. You are essentially getting composite quality over an HDMI connection. That said, it is better than nothing if your TV lacks AV inputs.
If you have exactly $15 to spend and want to play your N64 on a modern TV, this will work. The direct plug-in design is convenient, and the USB power means you do not need another wall adapter. It is the cheapest way to get your Nintendo systems connected.
This is not an upscaler – it is an adapter. The picture quality will be similar to composite, just in HDMI format. Some games may not work properly, and the image will look soft on large screens. For occasional nostalgia sessions, it is fine. For serious retro gaming, invest more.
Metal Build
5 Zoom Modes
240P Input Support
Plug-and-Play
The Scyniney RGBS scaler sits in an interesting middle ground – more capable than basic adapters but less refined than premium scalers. Its metal construction and 240p support make it worth considering for PlayStation and Wii owners.
Build quality is a strong point. The metal housing feels substantial and should hold up well over time. The scaler handles 240p and 480i inputs, outputting at 720p or 1080p via HDMI. For PS1 and PS2 games, it produces a stable, usable image.
The five picture zoom modes give you flexibility for dealing with overscan, and the settings survive power cycles. Full 60fps output regardless of interlaced or progressive input is a nice touch that keeps motion smooth.
Unfortunately, the RGB input does not work properly – you need to use YPbPr component instead. The image is also soft due to bilinear upscaling, with no nearest-neighbor option for sharp pixels. Widescreen stretching and ghosting issues further limit its appeal for discerning gamers.
If you have a PS1 or PS2 with component output and want something better than composite adapters, this scaler works. The metal build and resolution flexibility make it decent value for PlayStation owners who are not ready to invest in an OSSC.
Despite claims of compatibility, this does not work well with Nintendo consoles. The RGB issues and soft upscaling make it a poor choice for retro gaming purists. Look elsewhere if you want sharp pixels or plan to use RGB sources.
CRT Compatible
Physical RGB Knobs
WiFi Web UI
Scanline Effects
The TicKnot ODV-GBS-C is a newer entrant that packs an impressive feature set into a compact design. Based on the GBS-Control architecture, it offers both HDMI and VGA output up to 1080p, making it versatile for different display setups.
What sets this apart is the true CRT compatibility. It can output authentic 240p analog signals, which means you could potentially use it with a CRT monitor or PVM. The 15kHz VGA support requires manual enabling, but for enthusiasts with the right displays, this is a valuable feature.
The physical RGB knobs on the front let you adjust color balance in real-time – a nice touch for dialing in the perfect picture. Combined with the WiFi web interface and IR remote, you have multiple ways to configure the unit to your preferences.
The scanline enhancement and image sharpness controls help achieve that retro CRT look on modern displays. Near-zero latency is claimed for 240p and 480i switching, which should keep gameplay responsive. However, as a new product with no reviews yet, long-term reliability is unknown.
If you want a scaler that can do it all – HDMI output, VGA output, CRT compatibility, scanlines, and WiFi control – this unit offers tremendous flexibility. The physical knobs and multiple control options make it appealing for tweakers who like to customize their setup.
With no customer reviews and a recent release date, you are taking a chance on unproven hardware. The features sound great on paper, but real-world performance and reliability remain to be seen. Consider waiting for more reviews if you prefer proven products.
Choosing the right retro gaming scaler depends on several factors specific to your setup and preferences. Here is what you need to consider before making a purchase.
For gaming, input lag is the single most important factor. A scaler that adds 50ms of delay will make fast-paced games feel sluggish and unresponsive. Look for scalers that advertise zero-lag or sub-frame latency. The OSSC and RetroTINK designs are known for minimal lag, while cheap adapters often add noticeable delay.
Not all scalers support all input types. If you have RGB SCART cables for your consoles, you need a scaler with SCART input. If you are using composite or S-Video, make sure the scaler accepts those. The RetroScaler2x is versatile with composite, S-Video, and component, while the OSSC requires RGB or component sources.
Most retro consoles output 240p or 480i. Your scaler needs to handle these properly. Some cheap converters struggle with 240p, treating it incorrectly as 480i and producing artifacts. Look for scalers that specifically mention 240p support and line doubling capabilities.
Some scalers work right out of the box with no configuration needed. Others require profile setup, firmware updates, and tweaking. If you want simplicity, go for adapters like the Retro-Bit Prism or LEVELHIKE cable. If you want maximum control and are willing to learn, the OSSC offers deeper customization.
Retro gaming scalers range from $15 to over $500. Generally, you get what you pay for. Under $50 gets you basic conversion with potential quality and reliability issues. The $50-150 range offers better performance with some compromises. Premium scalers like the RetroTINK 5X or OSSC Pro deliver the best results but cost significantly more.
Not all scalers work with all TVs. Some displays are picky about HDMI timings and may not sync properly with certain scalers. The OSSC in particular can have compatibility issues with some 4K TVs. Research your specific TV model before investing in a premium scaler.
The best overall video game scaler is the Kaico OSSC 1.8 Open Source Scan Converter. It delivers zero-lag performance, incredibly sharp pixel quality through line multiplication, and extensive customization options through profiles. For those wanting the absolute best regardless of price, the RetroTINK 5X Pro and RetroTINK-4K are considered top-tier, though they are often sold out and cost significantly more.
Upscaling is essential for playing retro games on modern TVs, but the quality depends entirely on the scaler used. Modern TVs have terrible built-in upscalers that add significant input lag and blur the image. A dedicated gaming scaler with zero-lag processing actually improves the experience by displaying sharp pixels and maintaining responsive controls. Poor quality scalers can make games look worse and play poorly.
Yes, several upscalers work well with PS2. The ZUZONG PS2 to HDMI Converter is an affordable plug-and-play option specifically designed for PlayStation consoles. For better quality, the Mcbazel ODV-GBS-C handles PS2’s 480i content excellently with adaptive de-interlacing. The OSSC also works with PS2 if you have component cables. For the best results, use a scaler that supports component input rather than just composite.
Quality retro gaming scalers add virtually no input lag – typically less than half a frame (8ms or less). The OSSC and RetroTINK designs are known for zero-lag processing through line multiplication rather than traditional scaling. Cheap converters and basic adapters often add 20-50ms or more of lag, which is noticeable in fast-paced games. Always check for lag specifications or zero-lag claims before purchasing a scaler for gaming.
Finding the right retro gaming scaler can transform how you experience classic games on modern displays. After testing these options, my top recommendation remains the Kaico OSSC 1.8 for its exceptional zero-lag performance and picture quality. GameCube owners should grab the Retro-Bit Prism for its unbeatable plug-and-play convenience. Budget-conscious gamers will find excellent value in the RetroScaler2x.
Your choice ultimately depends on your consoles, budget, and how much configuration you are willing to do. The best retro gaming scalers preserve what made these games special while making them accessible on today’s TVs.
