Bigger is Better

I play on a 23 inch screen. I also use my laptop monitor (15 inch) as a secondary screen. However, I find it very annoying to use both screens for poker. I primarily play on the 23 inch, then run lobbies and iTunes on the laptop. I play 6 games at a time, but I want to do more. The problem is that if I go up past 6 games, the size of the games shrink considerably... to the point where it is annoying and I'm constantly squinting. I'd be curious to know what monitors people use and how many games they multitable on those screens. After staring at a computer monitor at work all day, it's hard for me to squint at tiny poker tables...
