I'm using the latest Debian stable. I have:
HM903DT IIyama Vision Master Pro454 monitor
nVidia Quadro FX 1300 video card
I have searched around on google and in the forums for answers to my problem. I've seen a couple similar problems, but they were either resolved via things that haven't worked for me or no one posted an answer.
I'm using the latest nVidia drivers. When I start X, my monitor refresh rate is limited to 85 Hz regardless of the resolution. My monitor, according to the specs, can do 800x600 at 200Hz and 1024x768 at 162Hz. I have tried adding various mode lines to my XF86Config-4, but these invariably result in problems around the edges of the image. Here are the relevant sections of my XF86Config-4:
Code:
Section "Device"
Identifier "Videocard0"
Driver "nvidia"
VendorName "Videocard vendor"
BoardName "NVIDIA Quadro FX (version 1.0-6106)"
Option "Stereo" "1"
Option "UseEdidFreqs" "1"
EndSection
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Iiyama HM903DT B, VisionMaster Pro 454"
DisplaySize 360 270
HorizSync 30.0 - 132.0
VertRefresh 50.0 - 200.0
EndSection
When looking at XFree86.0.log, I see several lines like this:
Code:
(**) NVIDIA(0): Default mode "1920x1440": 341.4 MHz, 128.5 kHz, 85.0 Hz

(**) NVIDIA(0): Default mode "1400x1050": 155.8 MHz, 81.5 kHz, 74.8 Hz

(**) NVIDIA(0): Default mode "1280x1024": 135.0 MHz, 80.0 kHz, 75.0 Hz
None of the vertical refresh rates breaks 87 Hz.
I am told that I need to be able to get at least 120 Hz to use the stereo capabilities of the video card correctly. I am looking for some suggestions on things I might do to enable higher refresh rates or pointers to areas with more information about EDID, monitor refresh rates, etc.
