I am running a triple monitor setup (three S2817Q) off of an Asus ROG Poseidon GTX 1080 Ti video card. This card has two DP ports (DP 1.4) and two HDMI ports (HDMI 2.0). But in Windows 10, when I select the S2817Q that is on the HDMI port, 30Hz is the maximum refresh rate available. I have seen in the specifications that this monitor is 4k and HDMI 2.0 but not sure why I cannot select 60Hz refresh rate.
For my notes, send me via Private Message the HDMI connected S2817Q service tag number.
The S2817Q HDMI "out of box" will operate at 4K 3840x2160 30Hz
