Match the console’s video output to an input on the TV. If they do not match—or the TV has only HDMI—use a compatible console-specific HDMI adapter or a retro-gaming scaler between them. For older consoles, check 240p compatibility, enable the TV’s Game Mode, and use a 4:3 picture when the game is designed for it.
Choose the connection that matches your console and TV
Start by identifying the console’s exact model and inspecting both its video port and the TV’s rear or side inputs. Connect directly only when the TV has a matching input and can display the console’s signal. If the TV is HDMI-only, the console’s analog output needs an adapter or scaler that converts it to HDMI.
Do not assume a TV has composite input just because it has red, green, and blue component jacks. Composite video typically uses a yellow plug; component video uses separate YPbPr video connections. The correct cable depends on the console, its revision, and sometimes its region.

|---|---|---|---|
| Direct analog input | Connect the console to a matching composite, S-video, or component input on the TV. | A TV with the exact input that accepts the console’s video signal. | TV scaling and lag vary, and many modern TVs omit analog inputs. RGM Retro’s connection guide discusses these options. |
| Basic composite-to-HDMI converter | Send composite video and stereo audio into a converter, then connect its HDMI output to the TV. | A simple trial when composite is the only available console output. | An advertised HDMI output resolution does not establish good 240p handling, low latency, or clean scaling. Elgato documents 720p or 1080p output for its Mini AV2HDMI in a legacy capture workflow, not as a general quality guarantee. Elgato’s support article also notes that display compatibility can vary. |
| Console-specific HDMI adapter or cable | Use an adapter made for a particular console’s AV or digital port to output HDMI. | A convenient setup when the adapter supports the console and its revision. | These products are model-specific. The cited RGM Retro guide describes a Hyperkin 3-in-1 cable that uses S-video for supported systems; it does not fit every revision. |
| Dedicated gaming scaler or line doubler | Connect the console’s analog video to the scaler, then connect the scaler’s HDMI output to the TV. | Multi-console setups and systems that output 240p. | Match the scaler’s inputs to the console and check support for 240p, 480i, resolution changes, regional standards, and aspect ratio. The RetroTINK 2X Pro reference is one model-specific example. |
| Internal HDMI modification | A hardware modification adds HDMI output inside the console. | Enthusiasts prepared to modify console hardware. | This requires opening or modifying the console and is not the simplest first hookup route. See RGM Retro’s overview. |
Understand the video signal before choosing an adapter
Composite, S-video, component, RGB, and VGA
Composite combines brightness and color in one video signal. S-video separates them. Component carries video across YPbPr channels and is available on some later analog consoles. RGB/SCART can provide a higher-quality analog route, but in North America it usually requires a compatible display or a scaler. The best connection is the highest-quality signal supported by both the specific console and the device receiving it—not simply the cable with the most plugs. See RGM Retro’s connection guide and RetroRGB’s 240p explainer.

Why 240p compatibility matters
Many pre-HD consoles output 240p, a progressive signal commonly described as approximately 320×240. Console and game output can differ: RetroRGB gives SNES 256×224 and Genesis 320×224 as examples, not as a promise that every game uses those exact active dimensions. Modern TVs and generic converters may not handle 240p as expected. A retro-focused scaler designed for that signal is a more appropriate choice when a basic converter produces a poor picture or no image. RetroRGB explains the signal, and RGM Retro covers console connections.
Check 480i and resolution changes separately
Support for 240p does not guarantee equally good handling of 480i. Some basic line doublers deinterlace 480i with a Bob method, which can produce visible flicker. Some games also switch resolutions during play, briefly interrupting the picture on certain scalers. For example, the RetroTINK 2X Pro reference lists composite, S-video, and component inputs and line-doubles supported 240p/480i to 480p; it says 480p input is unsupported, 480i uses Bob deinterlacing, and resolution switches may briefly interrupt video. Treat this as a product-specific example, not a universal recommendation.

Check console model and revision before buying
Port availability and cable compatibility can change between revisions and regional versions. These examples reflect the models and regions described in RGM Retro’s guide; verify the exact console in hand before ordering.
- NES and other early systems: Confirm the console’s actual output and regional cable standard. A line doubler designed for 240p is worth considering if the TV does not handle the signal well.
- SNES: The guide describes the first US model as supporting composite, S-video, and RGB, while the later SNES Jr. (SNS-101) is composite-only unless modified. Check the model before buying an S-video or RGB cable.
- Nintendo 64: US systems are described as supporting composite and S-video without modification; RGB requires an internal modification. An S-video-based HDMI adapter is a possible route only for compatible models.
- GameCube: Check the underside model number. DOL-001 has a Digital AV port; DOL-101 does not. Progressive scan requires a compatible game and must be selected at startup, according to the guide.
- PlayStation 1 and PlayStation 2: PS1 games often use 240p. PS2 supports composite, S-video, and component, with 480p in supported games. When using component on PS2, set Component Video Out to Y Cb/Pb Cr/Pr.
- Wii: Component is the route to 480p in the cited guide; Wii Mini is composite-only. Check the console’s output settings after connecting.
- Dreamcast: VGA can provide 480p for much of the library, but not every game supports VGA. Verify the individual game and use a scaler with VGA input if the TV has only HDMI.
Connect the console and configure the picture
- Identify the console: Read its model number and inspect the video port. Confirm the region if the cable or signal standard may differ.
- Inspect the TV: Check its rear and side panels for the exact matching input. Do not mistake component jacks for composite input.
- Choose the signal path: Use the best signal supported by the console and the TV, adapter, or scaler. For HDMI-only TVs, connect an appropriate converter or scaler between console and television.
- Connect video and audio: Attach the console cable to the TV or converter. If using a scaler, connect its HDMI output to the TV. Supply USB or external power if the device requires it.
- Select the inputs: Choose the matching TV input and, where applicable, the scaler’s active input. Power on the console and check for a stable picture.
- Set display options: Turn on Game Mode if available. If the image is stretched and the game was designed for a 4:3 frame, set the TV’s aspect ratio to 4:3. Choose progressive output when the console and game support it.
Reduce control delay and choose a sensible adapter
Game Mode reduces television picture processing and is the first setting to try if controls feel delayed. Lag still varies by TV, input, signal, and settings. RGM Retro gives a broad illustrative estimate of 5 to 10 frames of lag from a TV’s 480i deinterlacing; it is not a guaranteed figure for every television. No universal latency figure follows from a converter’s advertised output resolution.

For one console, a compatible console-specific adapter may be simpler. For several systems or a 240p-heavy collection, a scaler with the right analog inputs can be more flexible. Check the device’s input types and its behavior with the signals your games actually use. A scaler that handles 240p well may still be unsuitable for a setup that depends on 480p input or flicker-free 480i deinterlacing.

Troubleshoot a blank screen or incorrect picture
- No picture: Confirm the TV input and scaler input, check required adapter power, and reseat the video and audio connections.
- Still no picture through a converter: Verify console revision, regional video standard, and whether the TV accepts the converter’s HDMI output. Elgato notes that some displays fail to show a retro signal through the HDMI passthrough on its legacy capture device, illustrating that compatibility can be display-dependent: Elgato support.
- Image is stretched: Set the display to 4:3 when appropriate for the game instead of leaving it stretched across a widescreen panel.
- Picture flickers or briefly drops: Check whether the game is outputting 480i or switching resolutions and whether the scaler handles those conditions well. A scaler’s 240p support alone does not establish good 480i performance.
- Controls feel delayed: Enable Game Mode and avoid assuming a generic converter or TV input has low latency without device-specific evidence.
