We have a PC running XPP SP3 with a Gigabyte GA-G31M motherboard. This has onboard graphics and we want to add a PCI Express graphics card so we can view what's on the local screen on a 42" TV at the same time.
We have been able to do this using the external connection on a laptop, but I'm worried the PCI-E card will knock out the signal to the onboard card or if their is an override in CMOS to adjust this.
Anyone know? For a TV how much improvement does a higher quality card give? I'd say the TV is 720p rather than 1080p.
