[SOLVED]Help setting a custom modeline

Rubbishbook · 2012-02-29 23:32:37

Hi,
I recently bought a Samsung SyncMaster B2030 1600x900 monitor, at it needs a custom modeline to work at 1600x900. I've tried cvt and other modeline generators, but I specifically need a modeline that has the horizontal refresh rate as 60 Hz and vertical refresh rate of 60Hz. All the calculators I've tried have set different values for the refresh rate.

I have a dual screen setup, with Radeon HD 3850, running ati catalyst driver if it's any help.

Found an 'inf' file for the windows driver which I think contains the information I need... But I don't know which numbers are which.

Why do you need that?

What's xrandr's output?

Rubbishbook · 2012-03-01 03:04:58

I needed the modeline to set a new resolution as xrandr didn't show up the needed configuration, but switching the Samsung into the VGA port (instead of DVI) made xrandr recognise it. But found that out *after* I found the modeline (see below).

Managed to use PowerStrip on windows (which has a driver for said monitor) to obtain it. PowerStrip outputs the linux modeline:

Linux modeline parameters:
"1600x900" 108.021 1600 1624 1704 1800 900 901 904 1000 +hsync +vsync

found from http://www.x.org/wiki/FAQVideoModes#Obt … PowerStrip

Arch Linux
