Good day gents,
Upgraded yesterday from kaby lake to coffe lake as per my signature
After installing High Sierra 10.13.4 can not manage to have a 4K 30hz output from integrated Intel HD630/HDMI only
Getting a DisplayPort to HDMI adapter on Amazon worked for me - I now have 4k@60hz using the DP output. Also need to make sure you have an HDMI Cable that is certified to 18 gbps.
Please note - I had flickering issue when I updated to 10.13.4. All I had to do was change SMBIOS to 17.1.
Hope this helps.
