    I have a CTX P922E 19 Inch 1280x1024 LCD.

    This LCD only goes upto 1280x1024, it is designed that way.

    I just reinstalled my graphics driver. I ran driver cleaner in safe mode, booted to windows and Installed Ati (Omega) Catalyst 6.5.

    It rebooted, and to my total surprise booted into windows at 1600x1200.

    (I'm a graphic artist, I know 1600)

    The LCD was displaying the little OSD (hardwired) text saying range out of 1280x1024x85hz. But it was displaying 1600x1200! (one one screen!, i.e. no scrolling)

    Unfortunately catalyst drivers when they are first booted after install run some tests before they adjust themselves, i.e. resolution, etc etc. So after a few seconds and a few blinks of the display I had a normal 1280x1024 display, and surprise surprise the slider in display properties only goes upto 1280.

    Does anyone know how to force a higher resolution that in display properties?

    I.e. editing the .inf file of the driver maybe?

    The obvious question is how the hell does a 1280x1024 19" LCD display 1600x1200.

    I was real surprised to see that.

    Catalyst Omega 6.5
    P4 3.2 Ghz
    800MHZ FSB
    512 Ram
    Ati Mobility Radeon 9600 Pro 128 Mb

    While it squeezed stuff to appear like 1600x1200, the quality would suck, since it really only has 1280x1024 pixels to display the image.
