How do you increase refresh rate from 75 Hz to 85Hz?

How do you increase refresh rate from 75 Hz to 85Hz?

Post by a » Thu, 01 Apr 1999 04:00:00

I think I need to modify the monitor section of my /etc/XF86Config file.

I'm running Mandrake 5.3 (essentially Redhat 5.2 + KDE 1.1) and kernel
I got the following info from my /etc/XF86Config file.

My 17" monitor can handle:
HorizSync 30-85, VertRefresh 50-120.

The modeline:

Modeline "1024x768"    85    1024 1032 1152 1360   768  784  787  823

is being used because the "best standard mode that your monitor and
video card can support for a given resolution is automatically used".
My monitors flip-down control panel shows horizontal sync is 62.2 kHz
and vertical refresh is 75 Hz

My question: Would modifying the mode line increase screen refresh
rates? If so, how would I change this mode line to give 85 Hz? I read
man XF86Conf and a few other sources but can't seem to find how to do
this. Thanks in advance for any help.


1. refresh rate 85hz in windows but only 75 in linux?

I have an AOC 19" flatscreen, with an sis 730 on board graphics card, i am
using kernel 2.4.20, and Xfree 86 v.4.2.1.

linux, only at 75hz, is this because the vid card driver is not perfect,
or is it the monitor, correct refresh rates are in the x configuration
file, 30-95, and 50-160.

how can i make the refresh rate higher?
