refresh rate :/

saneone · 2008-02-19 00:18:09

My LCD got broken, so I had to connect my old CRT - iiyama Vision Master Pro 451" 19" Natural Flat, which is capable of doing 1600x1200@92Hz and 1280x1024@107 Hz - few years ago I was using 1280x1024@100 Hz mode in MS Windows w/o any problems...
Now I can't force X to set refresh rate bigger than 75 Hz... I tried to add modelines generated by gtf to the Screen section, but it looks like they are just ignored...

KDE Control Center show only stupid "50" and "54" Hz
nvidia control panel also doesn't show higher frequencies to choose from...

I don't know if this still applies (I actually use TwinView) but this is from the nvidia driver docs:

Option "DynamicTwinView" "boolean"
Enable or disable support for dynamically configuring TwinView on this X screen. When DynamicTwinView is enabled (the default), the refresh rate of a mode (reported through XF86VidMode or XRandR) does not correctly report the refresh rate, but instead is a unique number such that each MetaMode has a different value. This is to guarantee that MetaModes can be uniquely identified by XRandR.
When DynamicTwinView is disabled, the refresh rate reported through XRandR will be accurate, but NV-CONTROL clients such as nvidia-settings will not be able to dynamically manipulate the X screen's MetaModes. TwinView can still be configured from the X config file when DynamicTwinView is disabled.
Default: DynamicTwinView is enabled.

In other words -- try adding

Option "DynamicTwinView" "false"

to the "Device" section in xorg.conf and see if that changes anything.

Now I can see in KDE Control Center two values - 60 and 75 Hz...
I don't see the screen, which I pasted in my previous post in nvidia control panel... only an info that refresh rate is 75Hz

I looked up the specifications for the monitor you are using:

Horizontal refresh rate: 30-115
Vertical refresh rate: 50-180

from http://www.monitorworld.com/Monitors/ii … ro451.html

These are the ranges you should have in xorg.conf:

HorizSync 30-115
VertRefresh 50-180

It doesn't change anything
