Not sure if this is the right place for this thread, so please point that out if it's not.

I have a f10 64bit, a 1280x800 screen and an nvidia 84000 gpu, which is beyond adequate for Fedora's purposes I think. What I don't get it that when I go to system>preferences>harware>screen res, the max refresh rate is only 60 Hz whereas I thoght Fedora could go much higher.
Question is, is this refresh rate normal for my screen? Or can I make it go higher, say 85 Hz?

If you use a flat panel, TFT monitor, you should leave it as it is.
if you have a big old CRT monitor, you may want to change it, but i think there are no CRT monitors with that resolution. ...

It is normal, no need to make it higher.

Use xrandr utility to check available screen resolutions and refresh rates:
xrandr -q

Current marked with asterisk. To change on-the-fly:
xrandr -s ABC[D]xEFG[H] -r XY.Z

EDIT: Takes effect immediately when you press <ENTER>.

best use the nvidia driver and nvidia control panel to setup nvidia graphics.

Nvidia driver requires a flag to be set in xorg.conf to enable certain xrandr features.

As LaKing says, LCD displays have a native refresh rate just like they have a native resolution. You should only ever use that refresh rate setting. LCD displays don't work like CRTs.

yes, I do use an LCD monitor (well, a laptop screen).
So I'll just leave it as is. Thanks for al the replies guys.
