U3100 refresh issues

[KingRyan]

I'm building my first cocktail cabinet and I'm using the Wells U3100 from the onboard video card in my Dell PC.  I can only get 640X480 at 60Hz to work properly, and in this setting I find many games don't work properly, as well as 800X600, in both cases the screen is all out of whack and everything is a blur, I end up having to plug a PC monitor in to see well enough to change it back to 640X480.  I've read many people say that they get great results at 800X600 at 56Hz, but I can't seem to set my refresh to 56Hz.  Do I need another video card?  If so, which is the best one for me to use?
Thanks!!!

Yep, a lot of video cards don't let you choose 56Hz.  I used a Matrox g400 with mine and it worked really well.  I also had fine results with an ati rage128, but you need to be careful when choosing that card, there are so many different versions and some don't have 56Hz.

hope this helps.

Yeah, that's the confirmation I needed.  I'll get an ATI and see how it runs, I appreciate it!!
