Yes. A Sega Genesis can connect to a modern TV using a compatible analog input, or an analog-to-HDMI scaler if the television lacks one. The right setup depends on your Genesis model, its AV connector, and the signal format the TV or scaler accepts.
Check your Genesis and TV before choosing a cable
The Genesis does not output native HDMI: its original video connections are analog. Start by checking the model printed on your console and identifying its AV connector. Genesis family models can use different connector styles, so a cable that fits one model may not fit another. Then check your TV’s inputs or manual to see whether it accepts composite video and audio.
Do not assume a yellow RCA-style input is available, or that a component-video input will also accept composite. TV inputs vary, so confirm the exact input type before connecting anything.
Connect with composite when the TV has the right inputs
For the Genesis Model 2, SEGA’s instruction manual documents a composite AV connection: the console-side plug goes into the console’s AV output, the yellow plug goes to the TV’s composite video input, and the white plug goes to an audio input. Then select that input on the TV. The manual says: “Insert the yellow plug on the Audio/Video Cable into the composite TV or monitor’s video input jack (or into the VCR video input jack).” (SEGA, Genesis Model 2 Instruction Manual)

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
This is the simplest route when the TV has compatible composite inputs. The manual also describes connecting through a VCR, but that is mainly a legacy option.
Use an analog-to-HDMI scaler if the TV lacks analog inputs
If your TV only has HDMI, use a scaler that accepts the signal from your Genesis cable and outputs digital video over HDMI. A scaler is not just a passive cable: it processes an analog signal for a digital display. Check the scaler’s listed inputs and its Genesis compatibility notes before buying.

RetroTINK describes the 2X Pro as line-doubling standard-definition analog inputs into digital video. Its input options include composite, S-Video, and component. However, its product page warns that Sega Genesis composite output may not work correctly and recommends HD Retrovision cables for Genesis (RetroTINK-2X Pro product information).
The RetroTINK 5X Pro page lists composite, S-Video, component, RGB, and SCART inputs, with digital output for HDTVs; it advises higher-quality connections for best results (RetroTINK 5X Pro product information). These are device-specific details, not a guarantee that every scaler will accept every Genesis signal.

Consider RGB or component for a cleaner picture
The Genesis can provide analog RGB as well as composite video. A compatible RGB cable connected to a scaler can provide an alternative to composite; some cables convert RGB to component for a scaler that accepts component input. These cables and connections are not universal: verify the console model and region, cable connector and wiring, and scaler input before purchasing (Genesis connection guide, RetroTINK-2X Pro, RetroTINK 5X Pro).
Be wary of products described simply as “HDMI cables.” The key question is whether the full signal path converts the Genesis’s analog output to a format your TV can display. Match the cable’s signal to an actual scaler input rather than assuming a cable alone turns analog video into HDMI.

Choose a connection path
| Option | When it fits | What to check |
|---|---|---|
| Composite AV cable directly to TV | The TV has compatible composite video and audio inputs. | Genesis model and connector; confirm the TV input is composite. |
| Composite cable to scaler, then HDMI | The TV is HDMI-only and the scaler accepts the signal. | Check the exact scaler’s Genesis composite advisory; some devices warn it may not work correctly. |
| RGB or component cable to scaler, then HDMI | You want a cleaner analog signal and the scaler accepts that format. | Verify console model and region, cable connector and wiring, and the scaler’s RGB, SCART, or component input. |
What to do if there is no picture
- Confirm the TV is set to the input you used and that the video and audio plugs are in the matching inputs.
- Recheck that the cable is designed for your exact Genesis model and connector.
- If you are using a scaler, confirm it accepts the cable’s signal format. A Genesis composite signal may be incompatible with a particular scaler; consult that model’s manufacturer notes.
- For a TV with HDMI-only inputs, verify that a scaler is in the signal path and that its output is connected to the TV’s HDMI input.
The specific TV, console revision, and regional video standard are not established here, and can affect which cable and scaler are suitable. Check the manuals and compatibility details for the exact equipment you own.
