Dual desktop with 37" Lcd

I have my desktop hooked up to my main 22" monitor through VGA (DVI output on my monitor went kaput :frowning: ) and my secondary monitor is my sharp 37" LCD through HDMI.

If I boot up into openSUSE 11.1 with the secondary monitor (tv) Hooked up, the fonts are extremely small on my main monitor and the only way to correct this is to detach the HDMI and just boot up using my main monitor.

Any idea how to correct this font size issue?

Changing the resolution changes window size and button size as it should but text remains almost unreadable.
