Learn how to hook up your NES, Genesis, or GameCube to a modern TV with our step-by-step guide. We cover AV to HDMI converters, upscalers, and common pitfalls.
Quick Answer
To connect a retro console to a modern TV, you'll need an appropriate video converter or upscaler. For most consoles, an AV to HDMI converter works well, but for better quality, consider a dedicated upscaler. Check your console's output ports and your TV's inputs to choose the right adapter.
Modern TVs have HDMI ports, but retro consoles output composite, S-video, or component signals. Connecting them requires a converter or upscaler. This guide walks you through the process, whether you're hooking up an NES, Sega Genesis, or GameCube.
We'll cover the basics of video signals, the types of converters available, and step-by-step instructions to get you gaming on your HDTV. We'll also highlight common mistakes and how to avoid them.
Understanding Your Console's Video Output
First, identify what video output your retro console has. Most consoles from the 80s and 90s, like the NES and Sega Genesis, use composite (RCA) cables with yellow, red, and white connectors. Later consoles like the GameCube and PlayStation 2 often support S-video or component cables for better quality.
Check the back of your console for the video output ports. Common types include RF, composite, S-video, and component. Knowing this determines which converter or upscaler you need. For example, the NES has an RF switch and composite out, while the GameCube has composite and S-video.
- Take a photo of your console's ports to reference when shopping for adapters.
Choosing the Right Converter or Upscaler
There are two main types of devices: simple converters and upscalers. A basic AV to HDMI converter takes the composite signal and converts it to HDMI, but it doesn't improve the picture quality. It's a budget-friendly option for testing your setup.
An upscaler, like the RetroTINK or OSSC, processes the signal to improve sharpness and reduce lag. These are more expensive but provide a much better experience, especially on large HDTVs. For most retro gamers, a good upscaler is worth the investment.
- If your TV has no composite input, an AV to HDMI converter is essential.
Connecting Your Console: Step-by-Step
Once you have the right converter, plug the console's AV cables into the converter, then connect the converter to your TV via HDMI. Make sure the console is powered off during setup to avoid any electrical issues.
Power on the console and TV, then select the correct HDMI input. If you see no signal, double-check all connections and try a different input. Some converters require external power, so ensure it's plugged in.
- Always use high-quality cables to minimize interference.
Troubleshooting Common Issues
If the picture is blurry or black and white, you might have a PAL/NTSC mismatch. Ensure your console and TV are both set to the same standard. Also, check that the converter supports the correct format.
Audio issues can occur if the red and white cables are swapped. Verify they match the color-coded ports. If you're using a SCART adapter, make sure it's the right type for your region.
- Test with a known-working game to isolate the issue.

Step-by-Step Connection Process
- Identify console output: Check the back of your console for composite, S-video, or component outputs. Note the cable type. This determines your converter choice.
- Acquire the right converter: Choose an AV to HDMI converter for basic setups, or an upscaler for better quality. Ensure it matches your console's output. Don't skimp on a converter if you want a clear picture.
- Connect cables: Plug the console's AV cables into the converter, then connect the converter to your TV via HDMI. Power on the console and TV. Select the correct HDMI input on your TV.
- Adjust settings: If the picture is not correct, check for PAL/NTSC mismatches, swap audio cables if needed, and try different HDMI ports. Persist until you get a clear signal.
Gear That Can Help
- Nintendo NES Placo Video Shooter Gun with Receiver: The gun uses standard AA batteries and the receiver plugs into the NES control deck and does not require batteries. Gun has a built in red light that also goes off when you pull the trigger. Not directly a video converter, but if you're setting up your NES, this accessory shows the kind of peripherals that can enhance your retro experience. It's a fun addition to your NES collection.
- SEGA Genesis 6-button Arcade Original Port Pad Black: Relive the controller that changed the game, and take it to the next level with the Officially-Licensed SEGA Genesis original port controller by Retro-Bit. Featuring a long cable and compatibility with original and most third party consoles. Once your Genesis is connected to your modern TV, a reliable controller like this ensures you can enjoy your games without input lag or connection issues.
Connecting a retro console to a modern TV is straightforward with the right equipment. Start with a basic converter to get going, and consider upgrading to an upscaler for the best picture quality. Remember to test your setup with a game you know works, and enjoy your retro gaming on the big screen!
