1920x1200 problems on 2nd Monitor

[drleo]

Hello:

I am trying (like many on this forum) to get my brand new 24" Monitor (V7 D24W33) to work. From the other postings, my problem seems related to "maximum clock speed". Even though the Max clock speed of my monitor is 165Mhz (as required by the HDMI standard), the Xorg.0.log file reports it as 135Mhz. I added to xorg.conf:

Modeline "1920x1200R" 154.00 1920 1968 2000 2080 1200 1203 1209 1235 +hsy
nc -vsync

along with:

Option "ModeValidation" "DFP-1: NoMaxPclkCheck"

and even a new 16x10 Modeline under 135Mhz (generated by cvt):

Modeline "1600x1000_60.00" 132.25 1600 1696 1864 2128 1000 1003 1009 1038

but nothing seems to give me anything better than 1280x720. All modelines get invalidated (Xorg.0.log):

...
(WW) NVIDIA(1): No valid modes for "1920x1200R"; removing.
(WW) NVIDIA(1): No valid modes for "1600x1000_60.00"; removing.
(WW) NVIDIA(1):
(WW) NVIDIA(1): Unable to validate any modes; falling back to the default mode
(WW) NVIDIA(1): "nvidia-auto-select".
(WW) NVIDIA(1):
(II) NVIDIA(1): Validated modes:
(II) NVIDIA(1): "nvidia-auto-select"
(II) NVIDIA(1): Virtual screen size determined to be 1280 x 720
...

I have attached my nvidia-bug-report.log. Can someone help?

TIA,
Leo.

This means your CARD has a limit of 135 MHz, not your monitor.
You can add an option to ignore the card limit (see README.txt), or get a new videocard.

Thanks pe1chl. Could you be more specific? You said:

> This means your CARD has a limit of 135 MHz, not your monitor.

so I searched the 5902 lines of the README.txt file for "ignore", "limit", "speed", and couldn't find anything useful, except for

Option "ModeValidation" "NoMaxPclClock" which I already have set in my xorg.conf (please see the log file I attached to my first message). Is that the option you were referring to or is there something else I missed?

Thanks,
Leo.

Yes that option should be used, but I think you should omit the DFP-1.
