What size Monitor for Lumidesk?

[main1event]

I've been using lumidesk now for over 1 year. I love its simplicity, however my biggest problem with it is programming. I'm using a 15" laptop and I have to consistently scroll up and down to see the controls on the right. I have a 17 channel fixture and now I'm considering moving to a 35 channel fixture. However, I can't go on this way. What size monitor would display most of the controls? I was checking out a 22" HP touchscreen computer yesterday.

I use a 17 inch monitor for playback and most of my programming and don't have an issue. Some programming I do offline and on my office computer with a 21 inch screen and almost everything is visible with a 17 channel 5r profile.
