Samsung 2343BWX

I just picked up a Samsung 2343BWX monitor and opensuse 11.1 - x windows didn’t appear to have a device description to support 2048x1152 60Hz. This is a 23" QWXGA 16x9 monitor. I created a custom xorg.conf to support this and am posting the relevant sections for anyone else that might have this or similar display.

Thank you for taking the time to post this information. I have been trying to get a Samsung 2343bwx working at native 2048x1152 with my older ATI Radeon 9000. Your post was the only information I found with enough specific detail to get my setup working at its potential.

The final key to getting this to work was to use probed data in /var/log/Xorg.0.log about 50% of the way down where the Radeon reports a “Supported additional Video Mode”. That gave me the info to fill out the modeline.

Here’re my relevant xorg.conf sections:

Section “Monitor”
Identifier “Monitor0”
VendorName “Monitor Vendor”
ModelName “SyncMaster”
DisplaySize 510 290

Comment all HorizSync and VertSync values to use DDC:

    HorizSync    30.0 - 81.0
    VertRefresh  56.0 - 60.0
    Option      "dpms"
    Option "PreferredMode" "2048x1152"
    UseModes     "Modes[0]"
