A first- and third-party peripheral for the Sega Dreamcast.
How it works
If pin #6 on the Dreamcast's A/V out is connected to ground, the Dreamcast switches to VGA mode [1], displaying 640x480p60 (Progressive Scan, EDTV standard) at 31kHz in RGBHV which allowed it to connect to a computer monitor or EDTV/HDTV with VGA in.
The VGA adapter itself consists of merely a plastic case providing space for the VGA port and AV out (Composite, S-Video, and audio via RCA and TRS).
Competitors
Although there were various first and third-party progressive scan VGA adapters for the Microsoft XBOX, Sony Playstation 2 and Nintendo GameCube, they converted the YPbPr component video signal to the RGBHV format needed by VGA as none of these consoles were capable of producing a native VGA signal.
Unlike Dreamcast, they used YPbPr component video cables for progressive scan output on compatible games, and progressive scan was very poorly supported among PS2 & GCN software.
HDMI conversion
It is possible to convert the VGA ouput of the Dreamcast to HDMI via a VGA to HDMI converter, allowing the Dreamcast to connect with HDTVs lacking a VGA port.
Versions
Third-party versions were identical to SEGA's model, with the exception of the VGA cable by Blaze, which lacked the additional A/V out.
Although the accessory was produced in great quantity, an official VGA box can go for around $50US on eBay, while third-party boxes are often sold for under $20US on eBay and other websites.
Compatibility
Most Dreamcast releases were officially VGA compatible. [2]
There are a handful of European and North-American games that did not include the necessary flag within the boot sector on the disc ('IP.BIN') thus preventing the Dreamcast from booting in VGA mode.
Unplugging the VGA box while booting a game, or boot discs like DC-X can be used as a workaround.
