Screen resolution

[csd88]

I can't get my resolution above 1280x1024, I'm on a 27" monitor wanting to set it at 1900x1200 but the disc I used previously no longer works.

The maximum resolution you can get is limited by the physical characteristics of the monitor. The size is irrelevant.
What monitor do you have?

Right click on your desktop, and you should see a screen with a range of resolutions that are physically possible.

you said the disc you previously used no longer works--so presumably you had it at 1900 x 1200 before--try updating or uninstalling and re-installing your graphics driver
