Cant change monitor resolution

Postby Antony » Tue Apr 04, 2006 5:05 pm

Hi all Im running Debian on a Compaq Proliant ML370 server. I have a Compaq SVGA (472p) monitor attached to it. For a reason I cant fathom out I can only get a resolution of 640x480. I know its capable of more as I had it running fedora 4 at 800x600. Can anyone help please? (Make it nice and easy as Im a newbee to Linux. The following is part of the XF86Config-4 script:

Extracted from the monitor3.inf file:

Code: Select all
[SVGA.AddReg]
HKR,"MODES\640,480",Mode1,,"31.5-38.0,60.0-72.0,-,-"
HKR,"MODES\800,600",Mode1,,"35.2-38.0,56.0-60.0,+,+"


It would suggest that your HorizSync and VertRefresh values are wrong.

Try:
HorizSync: 35.2-38.0
VertRefresh: 56.0-60.0
