Montior Resoltuions

With a 1600x1200 resolution monitor, you can have four full size (800x600) tables on your screen with no overlap but with 1680x1050 resolution I don't think you can. 1600x1200 definitely gives you more surface area to tile your tables and if you play on Stars then you can probably fit more if you resize them with no overlap. Personally I like playing when tables don't overlap each other so I don't miss any action or do misclicks.

So in conclusion 1600x1200 > 1680x1050 imo.
