New lcd monitor out of range error fedora core 1
 

Hello,

I have been running Fedora Core 1 for quite a while (should update to Fedora Core 4 soon) and just bought a new lcd monitor (BenQ T705). When I try to log on to Fedora I get an "out of range" eror from the monitor. I looked up the specs for my monitor and added to the lines

HorizSync 30-83
VertRefresh 56-76

to my XF86Config.new file under the "Monitor section and tested the new config file, but still got an out of range error. Any guesses as to what I should do next?

Sincere thanks for any help!

I would put the old monitor back on the system and upgrade to FC3 or 4....then put the new monitor on and it will most likely work...

Do an upgrade of FC1 (as opposed to a fresh install) and you won't lose any data !!

Hi Rob,

Thanks for replying. Unfortunately I don't have the old monitor anymore, but that a good idea otherwise.

I'm running dual boot with win XP, is it an easy matter to simply upgrade to FC4? I've heard that sometimes upgrading directly from one version to a newer one can cause problems, and that the safest cleanest bet is to back-up data, wipe the partition, and do a clean install of the new version. Is this correct?

Any other suggestions?

Thanks again

I haven't tried doing an upgrade FC1 to FC4 due to my ancient computer....however....I did upgrade Mandrake 9.2 to 10.1 without any problems arising !!

Of course....backing up all of your important files is always a good idea whenever doing a major procedure on your box...

Hi,

I decided to upgrade my FC1 to FC4, and it seemed to go fine. However it still hasn't fixed the problem with the monitor. I still get an out of range error from the monitor when I try to log in and can't see anything. Any more suggestions?

I was hoping that FC4 woudl have the needed driver for my monitor, but alas that doesn't seem to be the case.

Thanks

Monitors don't need (have) drivers. The only thing that the 'driver' is, is a list of the resolutions and frequencies.

Does the monitor give frequencies during the 'out of range' message?

Sounds to me that the new config is not used by X (or not correctly used by your video card).
1)
How did you tell X to use the new config file; maybe it still uses the old one. I usually copy the existing one to a backup and modify the existing one.
2)
Are you using the correct driver for the videocard? What card do you have and what driver do you use.

3)
Make sure that there are no resolutions in your X configuration that are not supported by your monitor.
4)
You can try to set a lower maximum vertrefresh or lower horizsync.
5)
You can try to lower the max used resolution.

I guess that 4 and 5 is not what you want, but it's just to check.

run this command from command line


system-config-disply --noui( If u r using RHEL4).

This will create a new xserver config file for you.

ok....
