Unable to set monitor resolution

[notmatt]

I'm trying to get the resolution setup correctly on my 24" monitor. So far I'm not able to get any better then 1920x1080. It just goes out of the sync range and the screen goes blank if I manually change the xorg.conf to 1900x1200.

My aim is to have the 24" as the main monitor and then my old 19" as a secordary monitor using TwinView for Dual Screen. I had a similar problem with the 19" monitor when I was using it as the main monitor on 8.04, however in 8.10 it is detected the 19" correctly.

These are the monitor specs:

I've set the sync to the following, it's correct according the manual:

HorizSync 30 - 80
VertiSync 60 - 75

Also I've tried to put a modeline in with the correct settings, but that doesn't seem to help.

I've seen on google a couple of people mention that if you're using VGA cables the H and V syncs are slightly different, but I've no idea how to find that out. Any ideas? Would getting some DVI cables and plugging them in help? I've got a Nvidia 8600GT with a dual head DVI and I'm using DVI to VGA adaptors and VGA cables.

I've tried using gnome-display-properties but the doesn't even come close to the right resolution. So mainly I'm using 'sudo nvidia-settings' and trying to get it right in there, but it won't let me manually input the settings and doesn't give me a chance of selecting anything higher than 1920x1080.

I also tried to use the instructions here:

https://wiki.ubuntu.com/X/Config

But I just got a parse error when I restarted X.

Here is my xorg.conf as it stands. I'd like to have the 24" as the main monitor at 1920x1200 and the 19" as the secondary at 1280x1024. Is that too much to ask? Anyone able to help?

I have tested this out in Windows and I can get the correct resolution, so it isn't the fact I'm using VGA cables and DVI to VGA adaptors.

Any ideas anyone?

This is what I did to get my Dell 2405fpw to output the native resolution of 1920x1200.

That's kind of what I've tried already. I can't get it to do 1920x1200 on it's own either.

Apparently this new version of xorg does away with config files and auto detects everything, which leads me to think that a downgrade might be the way to go. Or even change distros.

Hi

Ok you guys are all going about this the long and hard way,

here is the fix, and tested and works on 2 different Dell Laptops with external 24" Monitors,

Dell models are D630 and D420


all you need to do is ...

# sudo xrandr -s 1920x1200

Go to Preferences-->screen resolution
and then it will ask you if you want to save the changes, say Yes

Thats it.
