The cable and scaler must match your Genesis model and its available video output. If you do not need original cartridges, a Genesis or Mega Drive Mini 2 is a simpler HDMI-connected alternative with its own game library.
Using an original Genesis and cartridges
An original Genesis does not connect directly to an HDMI-only TV with an HDMI cable. The console sends analog video; a scaler converts a compatible analog signal to digital video for the TV. The complete path is:
- Check which video output your Genesis model supports.
- Connect the console to a scaler with a cable that matches both the console and the scaler’s input.
- Connect the scaler’s digital video output to the TV.
- Power the scaler as specified by its manufacturer. The RetroTINK-5X Pro, for example, calls for a USB power source capable of 5V/2A.
Composite is a straightforward connection when compatible, but RetroTINK says it produces lower-quality video than S-Video, component, or RGB. A better signal is only an option if the particular Genesis model supports it and you have the matching cable and scaler input. An HDMI cable by itself cannot bridge the console’s analog output to the TV.
Choosing a scaler
RetroTINK-5X Pro: broad input support and output options
The RetroTINK-5X Pro accepts composite, S-Video, component, RGB, and SCART input and provides digital video output. Its manufacturer lists support for 240p input and output modes up to 1080p standard. RetroTINK publishes latency specifications of about 0.25 frames in Framelock mode and 0.25–1.25 frames in Triple Buffering. Those are manufacturer specifications, not independent test results. See the RetroTINK-5X Pro product page for the supported connections and modes.

- RGB SIGNAL REQUIRED, WHICH RULES OUT CLONE MACHINES: This adapter reads the RGB signal that an original console puts out, so it needs an unmodified original: for Sega Genesis Model 1, for Sega Genesis Model 2 or for NEOGEO. A clone, a replica or a heavily modified unit generally sends composite only, and the result there is sound with no picture. The adapter is also not built for Sega Master System or for Sega Saturn.
- TWO CONVERSION CABLES COME WITH IT, WHICH IS THE POINT: Those consoles do not all use the same video port, and a cable that will not physically reach the socket is where most orders for this kind of part go wrong. Two conversion cables ship with the adapter for exactly that reason, so one purchase covers all three machines instead of sending you back for a second connector.
- TWO BUTTONS SIT ON THE BODY OF THE ADAPTER: One steps the picture between the classic 4:3 shape and 16:9 widescreen, and the other steps the output between 720p and 1080p. Both are pressed on the adapter itself rather than buried in a television menu, so you can try the combinations on your own screen and settle on the one you like.
- WHAT ARRIVES, AND THE ONE PIECE THAT DOES NOT: The box holds the adapter at 7.5 cm by 4 cm on a 43 cm lead, two video conversion cables and one micro USB power cable. The adapter takes its 5 V over that micro USB lead, and the wall plug for it is not included, so count on a spare USB socket on the television or a charger you already own.
- PLUG IT IN AND PLAY, WITH ONE THING WORTH CHECKING FIRST: No driver, no software and no menu setup stand between the console and the television, so the adapter starts working as soon as both ends are connected. If sound arrives but the screen stays dark, the two usual causes are a console sending composite rather than RGB, and a micro USB lead that is not actually carrying power.
RetroTINK-2X Pro: check the Genesis composite warning
The 2X Pro accepts composite, S-Video, and component, and line-doubles standard-definition signals. RetroTINK describes it as a legacy product and warns that Genesis composite output may be off-spec and may not work correctly. For Genesis, the manufacturer recommends HD Retrovision cables. Confirm that the cable fits your exact console model and the scaler’s input before buying. Details are on the RetroTINK-2X Pro product page.
Why not assume a 2X MINI or generic converter will work?
RetroTINK explicitly does not recommend the 2X MINI for Genesis, noting that Genesis—and possibly PAL Mega Drive—composite output may be off-spec and may not function correctly. That warning is a useful reminder that compatibility depends on the console’s signal as well as the adapter. Do not assume a generic composite-to-HDMI converter is compatible without checking its documentation for your exact console and signal. See RetroTINK’s 2X MINI compatibility information.

Using a Genesis or Mega Drive Mini 2
If you are happy to play the games included with a separate mini console rather than use original cartridges, the Genesis/Mega Drive Mini 2 avoids the analog-to-digital setup: it connects to a TV over HDMI. In its 2022 announcement, SEGA said the Mega Drive Mini 2 would include over 50 titles and listed a high-speed HDMI cable among the contents. Regional naming and bundles can differ. This is a standalone console, not an adapter for an original Genesis. See SEGA’s Mega Drive Mini 2 announcement.

| Option | Use original cartridges? | Connection to TV | Key consideration |
|---|---|---|---|
| Original Genesis with compatible scaler | Yes | Analog console output to scaler, then digital video to TV | Match the console’s output, cable, and scaler input; higher-quality analog connections may be available depending on the model. |
| Genesis/Mega Drive Mini 2 | No; it plays its included library | HDMI | Simpler setup, but it is a separate console rather than a way to connect cartridges. |
