Uhhh... not use a 1280 x 768 monitor?

My 30" is 2560 x 1600. Your 37" screen is LOWER resolution than a 17" monitor (which is 1280 x 1024). No wonder it is hard to read!

I don't understand why people feel the need to play games on "HDTV" monitors or why they think they are suitable for video games. They aren't!

You only have 640 x 768 per WoW. On a 37" screen.

You can try fiddling with the fonts but my suggestion is to use a real computer monitor (doesn't have to be 30" but it needs to be higher resolution than that).
