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

Any suggestion?
Thanks everyone

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.

Which adapter did you get?

also isn't the 4k resolution too small? Can you get 1440p scaled hidpi?
