I got a nice HDTV lately and I wanted to connect it to my computer that already has 2 tfts connected. So i bought a HD 4350 PCI to run all three displays simultaniously. Using a 2nd PCI-E card would block the vent of my primary card, so I decided to buy a PCI card. Well it has just the purpose to either run the display of the 2nd monitor, or the HDTV, so i thought, that this would work out.
I connected the card, updated all drivers (catalyst and asus board drivers) and both cards are working.
The problem is, that the display of the PCI card is underperforming. When I just scroll this website up and down, it lags and the activity shown in the catalyst control center goes up to 90%. I can't display movies (on the 1440x900 display) without staggering.
I'm aware that the PCI bus is not suitable to display massive 3D action, but as the card is promoted as "FullHD ready" and "an ideal solution for home cinema" i thought, that it should at least suit to run the secondary display (browser, teamspeak, 2D tools) :-(
Maybe there is a bottleneck in my hard- or software configuration i couldn't figure out yet. Any advice is welcome
