I have Desktop with configuration Pentium 4,945 intel chipset board,dual booting with win 7 and ubuntu 10.10 (no graphics card) Recently i purchased Dell IN2020M 20" with native resolution of 1600x900 but my display allow maximum of 1024x768 because of this when i play any video in full screen mode it doesn't play smoothly or frames are refreshed jerkily

I have tried updating my VGA driver but its doesn't helping me much. Is there any way to solve this problem ?

1>if i want to replace monitor what maximum resolution should i buy ? 2>if i want to upgrade(graphics card/motherboard) my desktop what is the minimum configuration to support the current system.

Thanks in advance

You could try if anything changes when you install the dirver for the monitor (yeah there actually is such thing). It should be shipped on a CD with the monitor or you can download it on the dell website ( ??)
