can only run 3 monitors at a time on it. If I plug a 4th monitor in, it will not recognize it. However if I unplug one of the three that are working, the card then recognizes the 4th monitor. Any suggestions!?
Just a thought but, have you tried running your screens at 30 Hz? The card is designed to run 3 4k panels @ 60 Hz or 4 - 6 4k panels @ 30 Hz. It could be that even if you're not using a 4k resolution, you still can't go beyond 30 Hz at more than 3 panels.
