Getting X to work with LCD Monitor / Screen In Mandrake

Hello,

I just got a new LCD monitor, Planar 191M from Dell. The monitor works great with XP and nearly great with Mandrake 8.0. There is a strip at the top about 30-40 pixels wide that is shifted right about 7-10 pixels.

I am set at 1024x768x16. I used custom setting at Horz. 31.5-67 and Vert 50-71.

Using the plug and play setting or various other generic settings don't improve anything.

The rest of the screen is fine. I don't get it. :?

What could cause this? Help, please.

Dell online support seems to require a system number, since I only bought a monitor, I don't have a system number and Planar says they don't support Linux.

Thanks

I found the problem. Apparently if you have an ATI, which I do, you have to put an option in for the card, not just the monitor. The following fixes the problem, in the section

Section "Device"
Option "composite_sync" "False" # this line fixes all
...

Putting that option in fixes a sync problem. I did this and WHAM, great screen. It seems that the ATI cards don't sync well with composite sync to an LCD screen, :roll: any LCD screen. I read where someone else had the problem with an ATI Mach 64, I have the Radeon, but both use the ATI driver.

It be happy :D

Glad to hear you got it working.

And I'm sure it was much more satisfying to fix it on your own! ;)

I found the information when I was looking for someone who sells computer case power switches, (the one on the front, not the supply). Go figure. :roll: I don't know X well enough to have figured that one on my own.
