Xorg, Nvidia and Monitor problem

kzlazy · 2010-10-28 08:14:00

It all started when I saw a strange startup problem (lower resolution than my usual 1366X768) and some startup messages, on my system (Pcc tower plus a Sony Bravia 32' TV, that I use as a monitor. I started this thread https://bbs.archlinux.org/viewtopic.php?id=105910 but soon realised my problem was elsewhere. Reviewing the xorg log I see that xorg is unable to read EDID from the monitor and falls to auto-selection of resolution resulting to a 1024X768 (further on DPI calculation is also affected). So, has anyone had the same problem or has any idea?

I should mention that I use a VGA cable (there is a possibility that I messed things up when I tried an HDMI cable once or twice, not sure though, maybe the problem was already present, I can't remember), and that when running the nvidia settings manager, I do not get the desired 1366X768 option. The best option is the 1024X768. Needless to say that my TV is widescreen. Ideas please...

Have you tried to extract the EDID info from the TV set manually ?

Check out: https://aur.archlinux.org/packages.php?ID=13706

Then you could load them via Xorg command,

Does your VGA cable have all pins? There is also a possibility that your TV does not transmit EDID information. You can probably find the correct information on the internet somewhere (or in the manual), and set it manually in xorg.conf.

nvidia proprietary drivers do have problems to get EDID data. nouveau drivers, for instance, is much better for this.
I had a similar problem with my screen, have a look at : https://wiki.archlinux.org/index.php/Nv … ly_display
