A:Answer This card will recognize only 4 monitors at a time MAX. Yes, it has 3 Displayports, 1 Hdmi, and a USB C... but the computer will ignore any monitors past the 4th one. For example, I have 3 monitors on Dp and 1 on USB C. I also have HTC Vive on HDMI, but have to disable or unplug one monitor for my pc to recognize the Headset. Windows considers your VR headset as an additional monitor.
This is a year late, but applies to most NVidia cards. Just keep in mind that # of ports does not equal # of monitors. Hopefully this response will help someone in the future.
