[Solved] High Sierra 10.13.1 No resolutions over 1080p over HDMI

[knovoselic]

Hi!
I have ASUS Z97M-PLUS/i7-4790K/GTX 970. I just did a clean install of High Sierra 10.13.1. SIP is disabled. Have installed Nvidia Web drivers 378.10.10.10.20.107. No matter what I do, I can't get my main monitor to show picture using 4K@60Hz over HDMI. I have another 1440p monitor using DP and that works fine.
I've tried mac-pixel-clock-patch-V2, but it doesn't work for High Sierra (says Unknown version of...).

I'm really confused as before I had 10.10 Yosemite and 4K display worked perfectly. Is there anything else I can try to get it running?

I've tried the pixel clock patch on High Sierra (didn't work at the time) and on older MacOS versions (both Yosemite and Sierra) - didn't work on any. In the end I read somewhere that HDMI is and will never fully be supported on MacOS, so I just bought

works perfectly dual monitors, sleep, turning monitors off and on.
