Get the right monitor or set the resolution down - Linux just looks too small on a large hi-res monitor of today. I went to the electronic surplus place and got a couple squarish 19" LCD monitors (2x1280 x 1024) so much easier on the eyes.
Also, I'm using a laptop for my Linux install, there is no scope for an external monitor. The requirements really are quite simple. A UI that isn't bulky.
