Default PC to Plasma TV. Two video cards or One with dual output?

* Paul:
The board should have been able to interface to a PCI video card.
But the thing is, PCI has a bandwidth of 133MB/sec, which is pretty
slow. If you had a big bitmap on the screen to update, it could be
slow.


Not really. PCI is fast enough for 2D even on high resolutions.

(I've tested that on a computer here. With a PCI video card,
a lot of stuff actually works pretty well. What doesn't work well,
is poorly written software that redraws its window over and over


Not really. It doesn't matter how often a Window gets "redrawn".

again. The window "stutters" as it is moved across the screen.)

A "stuttering" window is not a problem of the bus, it's clearly a driver
problem (i.e. DirectDraw not working properly) or a problem with the
hardware. Windows also often has problems with hardware acceleration if
multiple gfx cards using different drivers (i.e. cards with GPUs from
different manufacturers or different series).
