I have a case where I need to set up a situation where the user has a 22" & a 19" monitor facing her, and a 19" monitor facing away. I've got the first two plugged into the r5 240 card, and the 3rd one plugged into the motherboard. I can recognize all three and create one extended screen. What I want to do is duplicate the image on the two 19" screens. I can duplicate the 22" (primary) and one of the two 19"'s, but I want to duplicate just the two 19" screens. Any suggestions?
