If the monitor doesn't return its capabilities via EDID reliably, the
system will default to 1024x768.  Try "xrandr" and see what you get.
Here's a sample from my system:

[root at prophead tmp]# xrandr
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192
DVI-I-1 connected 1920x1080+0+0 (normal left inverted right x axis y 
axis) 598mm x 336mm
    1920x1080      60.0*+   60.0
    1600x1200      60.0
    1680x1050      60.0
    1280x1024      75.0     60.0
    1440x900       59.9
    1280x960       60.0
    1152x864       75.0
    1024x768       75.1     70.1     60.0
    832x624        74.6
    800x600        72.2     75.0     60.3     56.2
    640x480        72.8     75.0     66.7     60.0
    720x400        70.1
DVI-I-2 disconnected (normal left inverted right x axis y axis)

If you don't see your 1920x1080 in there, then you can forcing it by
trying "xrandr --mode 1920x1080" to see if that'll bite.  If it does,
then you can add appropriate lines to your xorg.conf file.
