Hi and Merry Christmas! I just got a new monitor to add to my other two monitors (3 total) and I can't seem to get all three of them to work. Only two work at a time no matter what combination of cables I use. I tried getting different drivers with no luck. I am using a 7870 for all three displays. The 7870 is in crossfire with a R9 270x. I really want to use all my monitors so any help will be greatly appreciated. Thanks!
