When I plug my Samsung 906 BW flat screen using the DVI connections, for the first time, I appear to get a good digital connection, meaning sharp letters and the information screen on the monitor shows a match with the resolution/refresh rate shown on control panel. However, if I slide the resolution to a different value, the screen goes fuzzy and the monitor info readout does not match the computer resolution. It seems if I plug into the other digital port it will sometimes work. However, when you reboot, you get fuzzy. I have the latest driver for the 8800 GTX, but I didn't load any monitor drivers. I did that before I had to replace the hard drive, and that didn't make any difference.
