OT: How do I increase my screen resolution past 1024*768

[Dr_Jeckyl_00]

I want to try and play 2 tables at once, but I can't get the games side by side. I clicked on the desk top... properties...settings, but it tells me my max screen resolution is 1024*768 pixels. Now this seems weird since I have a flat screen monitor and a special high resolution graphics card (G Force or something). Does anyone know how I can increase the pixels so I can play two games or more at once? Thanks
