...display or driver problems? My computer is a fairly new Vista Ultimate (pre-installed) with duo core processor and a healthy nVidea video card. But I have a 17" monitor connected to it now. I would like to get a larger monitor. Will their be driver problems? How large should I go? Is there a way I can find off compatibility before buying the monitor?

No Tim,
Just make sure that the connectors on the G-card and the monitor are compatible

if it's a good enough nvidia card then you should have no problems. and the version of vista does not matter. what matters is the hardware, drivers, and nothing else. just set it to the right resolution (find the native resolution of the monitor and set the output to display in that resolution). but if you're worried about drivers, then the short answer would be no. you shouldn't go bigger than a 26 inch (no bigger than a 22 inch for gaming) unless you don't mind videos and stuff being very choppy. but if it's an nvidia 8800 series, then you can go all the way up to a 30 inch, just don't expect to be smooth (or anywhere near that) in gaming.

no driver problems, and if there are (there probably wont be) there should be a driver disk with the monitor. get as big a monitor as you like, compatibility is assured. but watch out for your motherboard! vista has killed 5 computers so far for me by SERIOUSLY overusing my motherboards (ie: pushing its limits for a little bit to long and then KABOOM ( i dont think SP1 has that problem so make sure you have SP1!) your computer (if you did not build it yourself and are a geek like me) will never work again, because OEM's tend to make computers that vista kills right after the warranty expires. If you built it yourself it is simply a matter of replacing the motherboard which is usualy impossible on OEM computers as OEM's love propriatary parts and connectors.
