I feel like I am running in circles with the

on the topic of drivers and videocards for the M10000 and lilliput.
I have the 7" TS and thought that getting a PCI video card would solve any problems with the monitor resolution. Before I buy the M10000, I want to make sure that I will be able to use the display correctly. Is the ideal resolution 800x648 or 800x640? I understand that the native is x640 but does x648 look better?
Can someone please recommend a video card or a way to setup the m10000 so that my display will be as it is intended to be? I am very lost in the whole mess
Thanks,
Joe
