Nvidia driver 8762 refusing to work at 85Hz

hansalfredche · 07-23-2006, 08:13 AM

Hi there

I have an Eizo T57s monitor (CRT) on a Nvidia 6800 graphic card. OS is Mandriva 2006 with kernel 2.6.12-24 and I'm using Nvidia drivers 8762 from PLF. My problem is, wathever I put in the xorg.conf file, the driver refuses to use 85Hz at 1280x1024 (definitely supported by monitor and card, using open drivers I have no problems with this setting). Could somebody tell me how I get the 85Hz back, actually it is only working with 60Hz.

I've already tried putting only 85 in the VertRefresh line, without success. The driver just ignored it.

Here's the xorg.conf file:

Try changing the 'Modes' line to read something like this

Modes "1280x1024_85" "1024x768_85" "800x600_85" "640x480_85"

instead of this

Modes "1280x1024" "1024x768" "800x600" "640x480"

hansalfredche · 07-24-2006, 12:27 PM

OK, I changed it, but now I get 1024x768@75Hz

Is there some way to tell the Nvidia drivers (not Xorg) to use a specific refresh rate?

puntjuh · 07-25-2006, 01:53 PM

I had that same problem when i picked my monitor out of the list. <Using SuSe 10.1>

I now use VESA .. And I can pick all Refresh Rates.. Here's my xorg.conf.

using latest Nvidia driver.. 7600GS

Hi, I tried using VESA, but it didn't changed anything. I only changed the settings for the "Monitor" section, should I have changed other things too?

hansalfredche · 08-31-2006, 11:03 AM

Hi

It seems I finally found the answer. As I supposed from the begining, the driver just overrides the settings in the "Monitor" Section and does as it pleases. Nvidia drivers get the configuration via Edid from the monitor directly. Unluckily some monitors like mine do not seem to give the correct information (or nothing at all?).

What one must do is adding to the Device section: Option "UseEdid" "FALSE"

As a result, all information concerning the monitor must be present (and correct!) in the Monitor section. Mind the DisplaySize option (in mm)

My actual xorg.conf
