Just put in a brand new XFX RX 580 XXX Edition, 3 DP ports. Trying to run triple monitor set up, 1st and 3rd DP ports connected to 27" Asus and 24" Asus monitors respectively. These two monitors work correctly, recognize in Windows, extend, etc. The second port is DP connected with a DP to HDMI cable to my 40" TV, yet it does not recognize no matter what I attempt to do. Does this card truly not run 3 monitors from 3 ports? Thanks!
