There were a very few mainboards made with Radeon chips that could 'partner' with a add in card; but not even all Radeon cards made at the same time as the main board. Only specifically listed cards would work in partnership with the on board chip. Almost all mainboards disable the on board video chip when a video card is detected. You will have to read about your MB video details. My guess is that your will soon be shopping for a pair of video cards that you can double up. It's not just the hardware that has to be compatible, the software has to be written to correctly manage all the monitors.
Sorry, there was a problem. Please try again later.The motherboard's BIOS can only run 1 video controller at a time, recommend; find an add on card that will support 4 monitors. One with 4 Display Ports for instance.
