screen resolution ? (newbie needs help)

Hi all,
I am new to linux/openSUSE.
I am dual booting with windows,and using a 32"lcd hdtv screen as a computer monitor.
I also,have a 8800gts with the lates drivers installed in openSUSE. I have openSUSE screen resolution set too,1360x768 pixils. The problem i’m having is that the icons,web browsers,email etc are way to big.
is there away to fix this problem? not sure what to do since i’am new to linux. any help would be appreciated.

Desktop Config/settings
depends if you are kde 3 or 4 or gnome

when i install openSUSE,I think i pick kde 4.

Configure Desktop - Appearance - Icons - Advanced Tab
