I bought a Matrox G550. I am using Windows XP Home. With the driver installed, I can go to Control Panel and I have a number of different color possibilities (up to 32 bit, high color) and different screen resolutions are available. But regardless of my choice, the number of colors displayed does not change, and all I have is a handful of basic colors (probably no more than 16). I have tried to change the number of colors with both the Windows XP provided driver, as well as the one on the CD that came with the card. Does anyone have any ideas on how to fix this? Also, if you are using a G550 card, what is the version and date of your driver?
