I have a sapphire 7950. It runs two monitors fine but when I try to add a third in the screen resolution settings it tells me that it is "unable to save display settings."
The monitors that I currently use are a Samsung T22B350 and a BenQ G2255. I'm trying to add a Phillips 170C. It's an old one that I'm going to use to keep track of how my machine is running.
So the card has two DVI ports and one HDMI port, the HDMI and one DVI (once changed to VGA) is used for my existing monitors (The Samsung and the BenQ). The second DVI goes (unchanged) into the Phillips.
All monitors work but I can only get two of them displaying anything at any given time. What can be done to make all three display at the same time?
