Use the command:
system-config-display

You will need the root user password.

Please post your video card chip set and brand+model of your monitor.

IMPORTANT: you have to prepare to edit the configuration files like xorg.conf manually in text mode via an editor like vi because if you mess up, you will not be able get a correct display to change your settings via a GUI. And I am no expert in xorg.conf.

It is possible that your monitor type is not detected correctly and thus your screen resolution is limit to 800x600 or your monitor simply do not support 1024x768 for a refresh rate 60-70Hz.

xrandr -s 1024x768

The problem I have is similar, but MY monitor runs best at 60 Hz refresh rate for 1024 x 768. And as far as I can figure on this, while my monitor will work at 85 herz, it works best on the 60 (starts squeeling about 20 minutes to an hour on 85 hz). But I can NOT find out which file needs to be edited to correct this. xorg.conf while showing the window or the refresh rate, does not seem to show a way to correct the problem.

On initial install, fedora 7 DID use the correct refresh rate, but at some time during the updating, it changed the refresh rate and the gui for resolution shows 85 hz as only option. And resolution disparity between screen and monitor. Not the same.

So plenty of room for almost any uses. But monitor and card are not identified correctly anymore. Ideas anyone?

Thank you.

"vesa" means the your video card is not recognized. You might want to try the ATI website for driver.

I think "Monitor 1280x1024" means you have a generic monitor capable of 1280x1024.

My personal experience:
I have a very old CRT. While my old on-board video card was detected properly, my monitor wasn't and I ended up having 800x600 as the max. I changed the monitor type to something like "generic CRT 1024x768" but then I saw multiple images! Then I tried to change the VertRefresh to something like 50.0 - 60.0 and it works for my monitor.
After I upgraded my motherboard with newer on-board graphics and install Fedora 7, I can't get it working. Poor me, I am using 800x600 at 60Hz right now. Anyway, my OLD monitor made high-pitch tone even back in the days I can use 1024x768 at 60Hz in Fedora Core 6.

@hferretluv
Set the maximum for the VertRefresh to 60 Hz in your xorg.conf and test. If that is not enough, add Option "UseEdidFreqs" "FALSE" to the device section in your xorg.conf.

No solution to Fedora 7 Resolution
 
I've searched and searched for a solution to this problem.

I am restricted to 800x600 resolution in Fedora 7

Dell XPS 410

ATI Radeon x1300

Tried ATI drivers, both ATI and Livna,

Tried editing the xorg.conf

i think i've tried everything, would love some expertise on this, great hardware system, great Operating System.

I have Planet CCRMA installed providing a custom kernal, i assume that might cause issues.

Any help would be most beneficial.

Regards
