Screen Distorted
 

I have a Philips LCD monitor Model 150E.
When I installed FC4, everything was fine. I updated the installed rpms using "yum update" command. Now my screen is all screwed up. If I set the resolution on 1024 x 768 the screen is too skewed on the right, if I set the resolution on 800x600 the screen is too skewed on the left. Manufacturer's recommended setting is: 1024x768 and this is the resolution I was using before update too. The HorizSync and VertRefresh rates are as per manufacturer's specifications

One more thing: The refresh rate is set at 75 Hz, which I cannot seem to change!, whereas the one recommended by manufacturer is 60 Hz

The xorg.conf settings are:
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Philips 150E"
DisplaySize 300 230
HorizSync 30.0 - 61.0
VertRefresh 56.0 - 76.0
Option "dpms"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 16
Modes "800x600" "640x480"
EndSubSection
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1024x768" "800x600" "640x480"
EndSubSection
EndSection

So how do I solve this problem ?

Adjust you monitor. Do not worry about the X config.

You need to use the buttons on your monitor.

To change your resolution

Goto

Desktop ---> Preferences ---> Screen Resolution
