Using the TV display

When I connect the television display and configure the output via Sax2, I have a peculiar problem. The output works, but the fonts (at the desktop,dolphin…pretty much everywhere) are WAY too small to read! I had this problem with openSuse 11.1 , and it’s still the same behavior with my fresh openSuse 11.2 installation (with KDE 4.3.4). Maybe someone knows an easy work-around or fix? Thanks in advance guys!! xDDD
