IchigoWalker Posted April 15, 2017 Share Posted April 15, 2017 HDMI + HDMI Sound works, but only 4k@30fps cause of HDMI version.Videocard IntelHD 5600 doesn't support HDMI 2.0 so i desided to use Displayport for 4k@60fps, but it just didn't work. So, there is no signal with 1080p monitor. It's a global problem with mdp on laptop.When I plug in the cable - system freeze for a moment, monitor offers to use displayport instead of hdmi (in monitor settings), but after a second - "no singal". I tried to use pixelclock patch, but no result. By the way there is no option in monitor settings to change pixelclock or displayport version.Also I tried this patch, but no results too. Also I tested this repo https://github.com/PMheart/CoreDisplayFixup. No success. Also I tried to attach DP port to the 0306 connector. Patch is working, but no success. All the conversations with RehabMan you can find on tomynac, but dead end there. I'm pretty sure that DP works by IntelHD (screenshot from Windows in attachments).On Windows displayport works properly 4k@60fps. Any ideas? Is it possible to make displayport work?
