Connecting the Sega Dreamcast to a modern TV
The Sega Dreamcast supports multiple video output options: composite, S-Video, VGA and (via an adapter) HDMI. VGA gives the best image — progressive and sharp — and is the recommended option if your monitor or TV has a VGA input.
What you need {#what-you-need}
Option A — VGA (best quality, if your monitor/TV supports it)
- Dreamcast VGA Box or VGA cable
- VGA input on your monitor/TV or a VGA-to-HDMI adapter
Option B — HDMI adapter (easiest)
- Dreamcast HDMI adapter (several brands)
Option C — Composite (works everywhere, lowest quality)
- Dreamcast AV cable (composite) — usually included with the console

Why VGA?
The Dreamcast is one of the few consoles of its generation that supports a progressive VGA signal. The result is a sharp, flicker-free image that looks surprisingly good on a modern monitor. Not all games support VGA — but most do.
Connecting via VGA
- Connect the VGA Box or VGA cable to the AV output of the Dreamcast
- Connect the VGA connector to your monitor or TV
- Also connect the audio cables (VGA carries no audio)
- Turn on the Dreamcast — most games start directly in VGA mode
No VGA input on your TV? Use a VGA-to-HDMI adapter (note: you’ll also need a separate audio input on the adapter, or use the composite audio cables).
Connecting via HDMI adapter
- Connect the HDMI adapter to the AV output of the Dreamcast
- Connect an HDMI cable to your TV
- Select the correct HDMI input and turn on the Dreamcast
Connecting via composite
- Connect the composite cable (yellow/white/red cinch) to the AV output
- Connect to the composite input on your TV
- Select the AV input on your TV
Note: not all games support VGA
Some Dreamcast games (particularly those using interlaced video) don't work via VGA. In that case you'll see a black screen or an error message. Connect a composite or S-Video cable as an alternative in those situations. A VGA Box with a switch makes this easier to manage.
Done
Via VGA or a good HDMI adapter the Dreamcast looks impressive on a modern monitor. Many people are surprised how sharp the image is compared to composite.
