Help with screen on Dell 8600

[gibs]

Just got my new Dell 8600 with 1920x1200 max resolution. I opened up four tables in PokerNow to see how it would look, but the four tables would not all fit on the screen (Yes I am sure the settings are set at 1920x1200). First off, when I open up a table, the table is smaller than the window that opens up, so there is an inch or so of black that goes around two sides of the table. Even if I position the tables so that they cover up the black part, they still don't completely fit. Can anybody help me with this? If someone can tell me how to post a picture I have a screen shot that I could post so you can see what I'm talking about.
