Unable to Change Monitor's Resolution

Unable to Change Monitor's Resolution

Post by Rajesh Rajesh Radhakrishna » Mon, 19 Jul 1999 04:00:00



Hi,

I bought a 17" Proview (EMC) SA-769 monitor that said it could run at

2048 Kbytes of video RAM.

I am unable to get it to run at 1280x1024 or even 1024x768. I am running
at the X server's default  resolution 640x480.

All I get is a blank screen with the 1000+ resolutions and Ctrl-Alt +/-
doesn't help at all.

I previously had a 14" monitor with which  I had no problems running at
its max resolution.

I have run out of ideas. I have tried XF86Setup, Xconfigurator,
xf86config and hand editing the XF86Config file.

Is there a problem with my video card/monitor. any errors or warnings to
look out for....

Any suggestions.

Thanks in advance
Rajesh

Are u using the correct horz and vert refresh settings ?
they would be listed in the manual accompanying the monitor.
Also .. check if is ur trident card is capable of handling the 1280x1024
resolution ?

Here, I think, is the problem...what color depth (bpp) are you trying to
run in? For 1280x1024 with only 2Mb of RAM, the best you'll be able to get
is 8 bit color, or 256 colors. If you go down to 1024x768, you can get 16bit
color, and so on and so on.

here, use my /etc/XF86Config file.
for RedHat its /etc/X11R6/XF86Config
its set to 1024x768.
if it works use it.
if you want to use that trident card to get a resolution of
1280x1024 you will have to run that old 16color vga.
and you dont want that.
1024x768 uses 8bit color which gives you 256 colors at 2MB Video Ram
which you have.
so go and edit that XF86Config file.
change your mouse settings only.
leave the rest alone.

Unable to Change Monitor's Resolution

Post by Rajesh Rajesh Radhakrishna » Wed, 21 Jul 1999 04:00:00


Hi,

I finally got my X windows to work at 1152x864 (17" Proview Monitor,
Trident TGUI9660 2MB video memory)

You certainly need a lot of patience :)

XF86Setup, Xconfigurator, xf86config didn't help at all. I only used
them to create the 'XF86Config' file then played with the XF86Config
file to get the max resolution that could handled by my video
hardware. Used 'SuperProbe' to find out my video memory.

I later found a 'comprehensive' XF86Config file on the Web which had
far more Modelines that the ones generated by XF86Setup,
Xconfigurator, xf86config.

The problem is to find the correct Modeline. For example, there will be
several Modelines 1024x768 but only one or two can be handled by your
video hardware configuration.

It helps to remove Modelines like 320x200 etc the ones which you will
never use and name the various Modelines that you are going to use
with seperate strings "1152x864A" "1152x864B" "1152x864C"  as shown
below (thanks to Dale for this great idea!),

Then type,

bash$ startx &> output_file

(the above command will not work on tcsh)

If it blanks  press Ctrl-Alt-backspace to quit X-windows and view
'output_file', you will see what went wrong. If none of your modelines
worked look around the web for other Modelines from other XF86Config
files. You will be surprised how many people have posted their
XF86Config files on the web.

Hope this helps.
Rajesh
