Monitor Resolution


FC14 running Kernel 2.6.35.13-92.fc14.i686 with Gnome and KDE desktop environments.

I have only one choice for my monitor resolution in my preferences 1024x768. It reads: "Monitor Unknown". I would like to run a higher resolution. Something in the 1920x1080 range. How can this be done? Do I have to change the .conf file? If so, what is the necessary command.

lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)

Thanks in advance.

Your config file has nothing to do with the capabilities of your monitor. If your system is seeing the monitor, it's going to identify the resolution it can do. It has. Your choices are: enjoy 1024x768, or buy a new monitor.

Would help if you told us what exactly your hardware configuration is...kind of video card, in what system, and what kind of monitor you have.

"Monitor Unknown" basicly means that EDID has failed, so its not IDing the possible resolutions avaible.

If the monitor supports higher than 1024x768, you might be able to play with the xorg.conf file to get higher resolutions.

+1 to TB0nes question, "what kind of monitor do you have".

My apologies, but I figured since it was a laptop it really didn't matter. But it's a Dell Inspiron 1545. But I know for a fact it supports 1920x1080 resolution, when I ran Windows 7 the resolution was never an issue.

Thanks again,

If it's just an EDID problem, you can easily create a new modline using gtf 1920 1080 60

EDIT: If TBOne is correct (post 6), use "gtf 1366 768 60".

Obviously the hardware matters. You never TOLD us it was a laptop, or what model, and you didn't say if you were using an external monitor or not.

Since you did, a quick Google search turns up that the highest that screen can go is 1366x768.

http://www.trustedreviews.com/Dell-I...on-1545_Page-2

Apparently, both Samsung and LG have made the screens for that laptop. These threads:
http://forum.nginx.org/read.php?30,158380
http://forums.fedoraforum.org/showthread.php?t=262768

have potential solutions, since your EDID isn't being correctly identified.

Yes, but that means little. You can look in most any forum, and find questions that don't belong there. Also, even if one assumes (always dangerous), that it's a laptop...not knowing what KIND, or what kind of monitor (external? Connected via VGA, HDMI? Or internal?) leaves out the important bits.

In all fearness, since he did mention Intel, I fail to see the dangerous advice.
I'm rather familiar with xorg and don't see any danger for the monitor (his info was imho enough if he didn't mention the wrong max resolution).

Creating a new xorg.conf using the result from "gtf 1366 768 60" should be enough.

"Assuming" is dangerous. The advice is very sound.
