NO 1680 1050 in my HD4200

I'm using winXP x32, a mon with resolution of 1680 1050 and HD4200(integrated)
The latest driver was installed; however, 1680 1050 still not exist in Windows Display Property and CCC.

I tried to connect the pc to mon by using both D-sub and HDMI(DVI is not supported ).There is no difference
The CCC provides form 640 to 2048, including 1440*900 and 1600*1200, but 1680*1050 is not provided.

I also connected the mon to another PC(win7).It was OK, so I think there is no problem with the MON.

Can anyone guess what the problem is?

  1. If the monitor worked on another PC how do you come to the conclusion that it is a monitor problem?

    It works on Windows 7, and doesn't work on Windows XP correct?
  2. Open Catalyst Control Center, Click on My VGA Displays -> Properties (VGA Display) and, uncheck "Use Extended Display Identification Data(EDID) or driver defaults", and set max resolution and refresh rate according to your monitor, and click apply.
