Modern TVs weren’t built for analog consoles. Here’s how to get a clean, low-lag HDMI picture from NES, SNES, N64, GameCube, Wii, Genesis, PS1, and more — explained in plain English for beginners.
Quick Picks (TL;DR)
- Fastest beginner route: Console-specific HDMI adapters/cables (cheap, plug-and-play; quality varies by console).
- Best overall image quality: RetroTINK or OSSC upscalers (handle many consoles, proper scaling).
- For GameCube purists: Digital output + adapter/cable for DOL-001 models.
How HDMI for Retro Actually Works (fast)
Old consoles output analog video (RF, composite, S-Video, component, RGB). Modern flat panels expect digital HDMI. You can either:
- Use a simple console-specific HDMI adapter/cable — cheapest and easiest; results vary by console and by brand.
- Use a quality upscaler (e.g., RetroTINK/OSSC) — costs more, but cleaner scaling, less smearing, fewer artifacts, and better deinterlacing.
- Mod the console (internal HDMI boards) — most expensive and technical, but can look incredible on certain systems.

Best Picks by Console (Beginner First)
Staying in Nintendo territory first (your most profitable niche). We include links to your controller guides for synergy.
NES
- Cheapest: Simple NES→HDMI adapter.
- Better picture, more $$: Upscaler route (RetroTINK/OSSC) from composite/S-Video/RGB as available.
- Controllers: See Best NES Controllers.
SNES
- Beginner: SNES→HDMI cable/adapter (fastest path).
- Quality jump: SNES RGB or component out into RetroTINK / OSSC.
- Controllers: Best SNES Controllers.
N64
- Beginner: N64→HDMI adapters (quality varies; try different brands if one looks soft).
- Better: S-Video/component (where available) into RetroTINK for cleaner scaling.
- Premium: Internal HDMI mods exist for N64 (advanced).
- Controllers: Best N64 Controllers.
GameCube
- Best case (DOL-001): Use the digital out port with a GC→HDMI adapter/cable: search options.
- Other models / composite only: Consider RetroTINK for better scaling from analog.
- Controllers: Best GameCube Controllers.
Wii
- Simple & cheap: Wii→HDMI adapters work well for most TVs.
- Sharper: Component cables into an upscaler can look cleaner than low-end HDMI dongles.
- Controllers: Best Wii Controllers.
Sega Genesis / Mega Drive
- Beginner: Genesis→HDMI adapters.
- Better: RGB SCART/component into RetroTINK / OSSC.
PlayStation 1 (PS1)
- Beginner: PS1→HDMI adapters.
- Sharper: RGB into RetroTINK for better scaling/processing.
Beginner Setup in 3 Steps
- Pick your path: Start with a console-specific HDMI adapter for a quick win. If you own multiple systems, consider a RetroTINK.
- Enable TV Game Mode: Cuts processing lag dramatically. See our Lag-Free HDTV Guide.
- Cable sanity: Use short, certified HDMI cables and avoid daisy-chaining adapters where possible.
Troubleshooting & Tips
- Picture looks soft or smeared: Try a different brand of adapter, or step up to a RetroTINK.
- Black bars / weird aspect ratio: Use your TV’s “Just Scan/1:1” or the upscaler’s aspect controls.
- Audio hum / noise: Check your power supply and avoid cheap, unregulated PSUs.
- Lag feels bad: Turn on Game Mode, keep HDMI short, and prefer upscalers over ultra-cheap dongles.
