Still confused about VertRefresh and HorizSync :(


Hiya,

I've just been given a HP Pavilion F1903 - Tech details at:

http://h40013.www4.hp.com/me/eng/con...627a_tech.html

I am running it at:

Resolution: 1280X1024, Horz Freq.: 63.98 kHz, Vert. Freq.: 60.02 Hz

Looking at the Tech details, it says:

Horizontal Scan Rates: 56-76KHz vertical, 30-82KHz horizontal

In xorgconfig, I get the following options:

hsync in kHz; monitor type with characteristic modes
8 31.5 - 64.3; Monitor that can do 1280x1024 @ 60 Hz
9 31.5 - 79.0; Monitor that can do 1280x1024 @ 74 Hz
10 31.5 - 82.0; Monitor that can do 1280x1024 @ 76 Hz 0

Here I think I enter 10. since my horizontal refresh is 30 -> 82 Hz

However, what am I meant to enter in this menu:


You must indicate the vertical sync range of your monitor. You can either
select one of the predefined ranges below that correspond to industry-
standard monitor types, or give a specific range. For interlaced modes,
the number that counts is the high one (e.g. 87 Hz rather than 43 Hz).


1 50-70
2 50-90
3 50-100
4 40-150
5 Enter your own vertical sync range

56-->76, should I be going for option 1? Should I go to the maximum frequency or is it not worth risking damage to the monitor?

If anyone could clear this up for me it'd be great

Thanks

Steve

why not choose 5 and enter your actual rates?

Hmm, good plan :P

I just edited my xorg.conf to read:

HorizSync 31.5 - 82.0
VertRefresh 56-76

Now the monitor reports:

Horz Freq.: 79.98 kHz
Vert. Freq.: 75.03 Hz

Cheers

Steve
