Windows 7: Secondary Monitor Resolution Problem

Secondary Monitor Resolution Problem

Im having an issue with my second monitor and can't seem to figure it out. Hopefully someone here has an idea.

Im running Win7 Ultimate and have just installed a new Sapphire Radeon 5850 video card with dual DVI. I hooked up my monitors, and the first monitor runs correctly and is detected as PNP, while the second (Acer AL2216W) is detected as a generic non PNP monitor.

The acers resolution is locked at 640X480 making it completely unusable. The default resolution of this monitor is 1680x1050 I believe.

Ive installed the latest catalyst drivers several times to no avail. I can not locate a 64bit driver for the monitor itself. Ive tried to install the 32bit driver for the monitor off of the Acer website, but when I go to update the driver, Windows tells me the current driver is up to date, and doesnt install anything.

Is there something Im missing? Both monitors worked fine with an old Nvidia 7900GT that I was previously using, but that card has now died. So whats the trick to getting this monitor to work?

Issue Resolved. Went through the monitors on screen menu and found that it was set to analog input for some reason. Strange since it was on DVI before and working fine. Anyway, changed to digital and the monitor now shows up correctly and is displaying at its default resolution.
