I have a real 4k monitor (LG31MU97) with a resolution of 4096x2160 @ 60Hz and was hoping I could switch with that but the monitor just sees black/no signal. If I resize it to 3840 x 2160 it works, or if I reduce it to 50Hz. It doesn't seem to do the full DP 1.2. I like the remote switch, but the display ports don't seem to support true 4k.
