Sonic Adventure - Sega Dreamcast

<- Back

These are screenshots of Sonic Adventure from the Sega VGA box's S-video Output compared to the regular Sega brand S-video output, and the Sega VGA box S-video stretched to 16:9 by Ati's MMC software. The supposition is that the aspect ratio of the widescreen image is similar to how it would look on an HDTV when using an upscan box to create a 720p image from the VGA box output.

The Naki VGA box's S-video output creates a dithering effect not present in the actual DC's output. This dithering is also not present when using the VGA output. However, the Sega brand VGA Box's S-video out (for regular televisions) does not feature any image quality differences from the regular Sega brand S-Video cables for the Dreamcast.

These S-video shots are also not representative of the image clarity of the VGA output. The VGA box's clarity is incomparible to the S-video outputs in either the Naki or Sega brand VGA box's case. S-video seems to add a bit of blur to the image, roughly that of a single "blur more" in Photoshop. Aside from that, both the Naki and the Sega brand VGA box seem to have the exact same image quality output, which is good news for any gamers out there who might want to try to play their Dreamcast on a monitor or an HD TV in 720p.

These are some snapshots of Sonic Adventure 2 taken with a digital camera from my Toshiba RPTV. The image is running through my VGA box, into a VGA to Component converter and then stretched to 16:9 by the TV set. As can be clearly seen, Sonic is not abnormally stretched wide, the screen looks fine. Obviously, the digital camera failed to catch the image quality though, on screen it looks better than the screenshots from S-Video on this page.
