GTX 1080 HDMI port doesn't auto-detect the monitor

I am running a GTX 1080 with 3 monitors. 2 of them are on displayport and one is HDMI. The one on the HDMI cable will not auto-detect the input after waking the computer from sleep or after turning the computer on after it has been off. I have to power-cycle the monitor itself in order for the display to work.

All 3 of my displays used to work fine, however. This particular issue only started happening a few weeks after I got my card. Has anyone experienced a similar issue with the GTX 1080 or 1070 with HDMI ports?

I've tried multiple cables and tried the cables on all 3 monitors. Each time, the HDMI connection doesn't wake the monitor and I have to power-cycle it.
