Higher than native monitor resolution?

garlick · 05-25-2004, 12:11 AM

I have a Dell Dimension 8300 running Fedora Core 1. I have a Dell 1901FP flat panel display monitor whose "native resolution" is 1024x1268. I had to install the ATI driver to get this monitor to work in the first place.

Is there any way to get a higher resolution like say 1200x1600? At 1024x1268, I can't cram as many windows apps on my screen as I am used to. I feel like one of those Windows users who makes their browser take up the entire desktop!

I have tried adding the higher resolution to my XF86Config-4 file (via the ATI config program), but it seems to skip it when I cycle through the resolutions with ctrl-alt-+. Here are the relevant sections from XF86Config-4:

well your screen section looks fine to me. don't know about the viewport 0 0 line in the Display subsection, though. i don't have that in my config file (but i'm also using nvidia). anyway, have you tried restarting X? ctrl-alt-backspace.

Yeah, I've actually been using this setup for about a week now, so the system has rebooted a bunch (thereby restarting X).

Maybe the question really is, can you even get a higher than "native" resolution out of the hardware of the monitor? Or am I stuck with 1024x1268?

Thanks,

-Tim.

if your monitor can make more than 1024x1268 and the vgacard can do so also there should be no problem. look at the tech sheet that was supplied with your pc or search the net. there should be something like "maximum resolution" for your monitor. for your vga-card you'll have to look at the documentation for that driver. if the fglrx-driver is from XFree86 you may find it there.
