Inverting monitor resolution.

iamnobody · 01-22-2007, 09:42 AM

Hello,

I am using Fedora core 6 on my Asus M2N-MX which has nVidia 6100 chipset on board.
I have Samsung 540n LCD monitor which has a native resolution of 1024x768.

The chipset was detected during install and the driver is specified in xorg.conf as 'nv'. Everything is fine at 800x600 (except for fonts which appear a bit blurred.)

But if I select 1024x768 as the resolution my desktop appears stretched out vertically. I see black strips at the left and right edges.

I guess this is happening because the system is rendering the desktop at 768x1024 instead of 1024x768.

Can somebody please tell me how to invert the system's resolution??

Thanks for your time.

I would suggest checking that the proper monitor settings are in the /etc/X11/xorg.conf file..

Monitor specs for your monitor state these values should be

Code:

Horizontal: 30~61kHz
Vertical: 56~75Hz

Verify these are correct in the "Monitor" section of your configuration file.. correct them if they are wrong and restart X

Code:

Section "Monitor"
        Identifier      "Section "Monitor"
        Identifier      "Samsung 540n"
        HorizSync       30-61
        VertRefresh     56-75
        Option          "DPMS"
EndSection

Did you try running xvidtune as root?

Hi,

I made the changes suggested in xorg.conf and voila it works!

I should say that I did not have any idea that refresh rates have something to do with resolution.

Thanks guys.
