Old consoles were built for CRTs. Modern TVs? Not so much. If you’ve ever plugged a classic console straight into a flat-panel and thought, “Why is this so blurry and laggy?”, you’ve run into scaling and processing issues. The fix is simple: use the right HDMI adapter or upscaler to convert those retro signals cleanly and with minimal delay.
Below are beginner-friendly picks that work well for SNES, NES, N64, PS1, and GameCube, with clear pros/cons and what to expect. Need controllers too? See our wireless controller guide. If you’re all-in on N64, bookmark Top N64 Mods & Upgrades.
Quick picks by need
- Cheapest “just works”: AV2HDMI converter — plug composite (yellow/red/white) into HDMI. Basic, fine for casual play.
- Cleaner per-console cable: console-specific HDMI cables — tidy and simple.
- Mid-tier visual boost: mClassic HDMI — mild sharpening/upscaling; great for 480p/720p consoles.
- Best overall quality: RetroTINK upscalers — purpose-built, low-lag, excellent picture (pricier).
Level 1: Quick & cheap (AV-to-HDMI)
These little boxes convert composite to HDMI. They’re the easiest way to see a picture on a modern TV.
Pros: Dirt cheap • Plug-and-play • Works with most consoles that have composite
Cons: Soft image • Scaling artifacts • Quality varies by brand
Level 2: Console-specific HDMI cables
These cables connect directly to your console’s multi-out port and convert to HDMI inside the cable. Great for SNES/N64/Genesis/PS1, etc.
Pros: Tidy single-cable solution • Usually better than generic AV2HDMI
Cons: Quality ranges • Some add minor lag • One cable per console

Level 3: mClassic (plug-in clarity boost)
The mClassic is an HDMI dongle that cleans up edges and adds subtle sharpening. It pairs well with consoles that can already output 480p or 480i, and can give a gentle improvement to 240p sources coming through adapters.
Pros: Plug-and-play • Noticeable clarity bump • Works across consoles and even Switch/PC
Cons: Not a miracle for very low-quality signals • Another device in the chain
Level 4: Dedicated upscalers (RetroTINK family)
Purpose-built retro upscalers handle 240p/480i content beautifully, with low lag and customizable settings. They’re the best image you’ll get short of a PVM/CRT.
Pros: Excellent scaling and deinterlacing • Minimal latency • Profiles per console
Cons: Cost • More settings to learn (worth it)
FAQ: Cables, lag & picture quality
Why does my TV add lag? Modern TVs process low-res signals heavily. A good upscaler feeds a clean, TV-friendly resolution that needs less processing—so inputs feel snappier.
Do I need fancy cables? Start simple. If you still see noise/softness, upgrade the cable or the scaler—then tweak TV settings (Game Mode helps).
Should I buy a CRT? CRTs are lag-free and look “right,” but they’re heavy and aging. A good upscaler on an HDTV is far more practical for most people.
Starter setups (pick your path)
- Budget casual: AV2HDMI converter + Game Mode on your TV.
- Console-tidy: Console-specific HDMI cable + your existing controllers (see wireless guide).
- Quality-first: RetroTINK upscaler + short, decent HDMI cable + per-console profiles.
