Im using a HP 800 G1 SFF PC – designed for businesses so it has two display ports, only. Its connected to a 4K Samsung Monitor.
I once tried to run a hackintosh on this and ran into the exact same issue with no hardware acceleration. Its just an intel i5-4670 with the standard integrated intel hd graphics. it runs fine on Windows 10, but Linux + Mac just dont run right. System overall is okay, when a browser is opened or a video is played, the issue is apparent – extreme lag.
Ive just updated the BIOS to the latest revision, and there is no difference. Linux Mint, and Ubuntu (both LTS and latest version) all suffer the same issue.
Is there anything I can do besides having to buy a graphics card?
