(newbie) how can I change the display resolution???

[c-3]

Hi!

Can anybody help me how to change my display resolution?
Right now I just have 640*480 with (I think) 16bpp, but I would like 
to have 1024*768 with at least 16bpp.
Is it right that I just have to change something in the etc/XF86Conf ?
I didn't change the values so far, because I don't want something to 
damage.

I'm using a Diamond Viper 330 with 4MB RAM and a Fujitsu 17" 
Monitor (Type "TE767B")
with a sync range of 100-240 (hor) and 50-60 (vert) (at least that's 
printed on it's label).

Thanks in advance for any help!
