Hello everyone this is my first time, please be gentle :)



the problem;
optimal monitor resolution is 1280x1024 @60hz but i cannot set my refresh rate lower than 75hz which as you can imagine it's a bit much for my system.

my system is a dell optiplex SX270 + E173FP monitor - my dell service tag is 52M871J

I can see my monitor model under
gksu displayconfig-gtk
but won't let me choose 60hz

I kinda know what xorg.conf is, sorta. i want to scream please help thnx

Per - http://ubuntuforums.org/showthread.php?t=199417 - Use "1280x1024_60" in your Screen section of the xorg.conf

If that doesn't do it, can we get a copy of your /etc/X11/xorg.conf ?

cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

nano /etc/X11/xorg.conf

Modify:


Section "Monitor"

EndSection

To look like this:


Section "Monitor"
Identifier "Configured Monitor"
Option "DPMS" "true"
EndSection


(your monitor is an LCD so refresh rate is actually not important - sorry I didn't realize that on my first post)

Change the monitor section to look like this: (make sure to remove "#")

Hello again ^o^/

I did it! I actually managed to get my refresh rate down to 60hz by editing out anything referencing 75hz and adding

Option "IgnoreEDID" "1"
Option "UseEdidFreqs" "0"from the thread you linked me to.

However at the welcome screen it does look sort of zoomed in towards the top left? but does fix itself once logged in.. knowing me i'll probably leave it like that as long as my refresh rate isn't making my poor cpu cry every time i watch a youtube video in fullscreen i'm happy.

My xorg.conf looks like this now.

Um, not following why there is a "Virtual" line in there. That is probably what is causing the zoomed effect. Furthermore, you have 1600x1200 in there multiple times and your monitor is not capable of those resolutions... (if I'm not mistaken) You should really remove those...

I think that monitor did actually support up to 1600x1200 but the optimal resolution was 1280x1024. Anyway it's ok now because i don't have that monitor anymore ): i had to give it back to it's rightful owner.

I'm now using an ancient HP CRT as a temporary replacement which wasn't as troublesome to set up as the LCD thankfully. Good news though! I'll be receiving my new 26" monitor fairly soon so i can watch my digital camera slideshows and HD content in widescreen, of course this means i'll have to buy a new pc because my integrated video card being limited to 4:3 aspect ratio only and i've been advised sternly to build a system instead of buying another dell, which makes sense because i'll only be paying extra for the windows operating system that usually comes bundled.. but you see the thing is, i don't know how to build anything lol.
