Lesser known feature was that the Matrox MGA/G200 chips were capable of delivering "sync on green" via regular VGA cable. This was a specialized format were VSync/HSync weren't transmitted over dedicated pins, but encoded into the green signal. This was required by some (then) older workstation monitors. In the early 2000s, I managed to get a 20" SGI workstation monitor for 20€ at ebay (at times where 20" monitors were above 1000€) - because no one could use them with regular PC hardware. Using a single "sync_on_green" flag in my XFree86.conf file, and it would work flawlessly on my linux box.
