Changing fonts dpi

Sorry if this is a very "newbie" question! I am trying, yet again, to get the fonts in SUSE9.3 looking decent on my 15" 1024x768 TFT monitor. They are thick and "blocky". I have tried the monitor driver which was selected on installation, the generic LCD driver and the generic VESA driver. Also hinting, and everything else I can think of. On another list, I have read that running fonts with a dpi of 96 could improve things. But I don't know how to change the dpi in SUSE. I can't find anything in the manuals, or in the list archives. Has anyone changed their font dpi, please? If so, how do you do it? Many thanks for any advice Keith
