After reading people's suggestions, I upped my screen resolution to 1280 x 960 and found it to be still readable. (19" monitor.) I had to tweak my Poser settings - menus got stuck off screen, I lost the background color repeatedly - still can't get the right color back, but overall, it's what I want.

Personally, I keep the dials to the left side of the screen as I am right handed. It's less distance between the keyboard and the mouse and I type in most of my dial settings. I spend most of my time with posing dials, so it's more comfortable for me.
