Blurred artifacts on Debian Etch

CM019 · 02-01-2007, 08:42 PM

I'm trying to change vertical refresh rate on my Debian Etch computer.
I've LG's L204WT LCD monitor. I want debian etch to use vertical
refresh rate of 1680x1050@60Hz(LG recommended). Now it is
1680x1050@57Hz and it is causing blurry effects on visuals and
my eyes are hurting. My video card is GeForce (nvidia) 7800GS 256MB AGP
card. I've given LG recommended horizontal and vertical refresh rate
in xorg.conf file. But I can't go beyond 57Hz. What should I do to
change it to 60Hz? Please help me.

Note:I've installed nvidia driver and can't change the vertical refresh
rate with "nvidia-settings" tool as that particular option is disabled.

What do you have configured for your monitor in your xorg.conf file? It should contain the following two lines for this monitor:

HorizSync 30-83
VertRefresh 56-75

Have you tried using the "nvidia-settings" utility to change it? This is just a thought, but remove the spaces and decimals in your monitor line numbers so it reads as follows and see what happens. Other than that, I don't see anything.

HorizSync 30-83
VertRefresh 56-75

Yes but that particular option is disabled so I can't change it.

I have done that. But still at 57Hz.

"I have done that. But still at 57Hz."

Well, sorry I couldn't help.

Is there no other way of increasing the vertical refresh rate to 60?
