Cant use monitor beyond low resolution
Last modified: 2005-10-31 17:00:50 EST
Description of problem:
I can't use a resolution beyond 640x800 without 1-overloading my monitor (one
of them got fried) 2-Without it my monitor turning of (my flat screen)
I got it work under 640x800 on my Compaq 5017m Flat screen
if i used anything beyond that the monitor says output out of range and shuts
I got it to work under 640x800 with my Digital PCXBV-KA but beyond 640x800 it
squeals, this monitor ended getting overload and stopped working.
How can I get it to work in a resuluton beyond 640x800( I cant see the enough
of the app windows to use them, everything is to big)
What monitor would could I use for 1024x768 or so resolution, I also need to
know how to change the X resolution from the command promt because I cant get
back into the linux GUI, i know how to start it, it is that the resolution it
is at 1024x800 or so turns off or overloads the monitors i have.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install linux
2. Increase the resolution
It varies based on the monitor and the resolution.
Monitor will eather have mulitple images, ghost images, squeals may get be
Computer is running a Micro-ATX MSI MainBoard. I can run Linux just fine in
640x800 but beyond that I can't
You can try the 'lowres' option when you boot anaconda, like:
I can install it under lowres but I cant run Linux above that, I "need" the
larger screen size so I can use the software on Linux. Every program ends up
desplaying out of bounds of the screen.
Assigning to redhat-config-xfree86 which handles post-install X configuration.
But how, i tried accessing that program from the command prompt but it runs but
what command lines do i used
I just tried all these monitors and none will work beyond the lowres at install
or post install for linux 9.0
Compaq:CV735: Mod# C040554
HP:ULTRA VGA 1280: Mod# D2807A
HP:HP MX75: Mod# P1499A
HP:HP ERGO ULTRA VGA: Mod# D1196A
These all work at the resolution 600x400 but above that they will not, i need
to get this machine working, its very critical.
I'm having a hard time understanding exactly what you're trying to say.
1) hook up the Compaq 5017m Flat screen
2) as root, run '/usr/sbin/ddcprobe'. What does the output say?
3) Delete /etc/X11/XF86Config file
4) Run 'redhat-config-xfree86'. Does the program even come up?
5) If it comes up, select "Generic LCD Panel 1024x768" and then select 1024x768
and then restart XFree86. Does that work?
Closing due to lack of information.
