Intel HD 4000 Glitches and bad resolution

[Andyapple]

Hi, I have installed successfully macOS Mojave on my PC with GA Z77x UD5H but I am having a lot of graphics glitches and problems with resolution. Graphic card is Intel HD 4000.






How can I fix this? Thank you. I am attaching files as said in Problem Reporting FAQ.

My monitor is a 4k, 3840x2160 connected with HDMI to Intel HD 4000. (I think I'll need help to force an higher resolution as 4k, because I think that intel hd 4000 supports max 2560x1440)

According to your hardware, Intel i5-3570 has Intel HD 2500 graphics:

The Gigabyte GA-Z77-UD5H has a maximum HDMI resolution of 1920 X 1200 (even with HD4000 graphics):

The biggest issue will be that macOS supports a maximum of 1920 X 1080 via a HDMI 1.4 port. To get higher resolution to suit your monitor a DisplayPort cable and a supported graphics card would give you the best solution. A non XFX branded AMD RX560 will give your support for DisplayPort connection and the 4K resolution for your monitor.

Thank you for your answer.
My CPU is intel i5 3570K, i could not write K in the build signature.

Oh i hope i could use 4k


Yeah I have a GTX 1050 Ti with DP cable that i use on windows for 4k.
I used it also on Sierra in 4k and it worked perfectly. Now on mojave, without nvidia drivers i was trying to use intel hd 4000,

Thank you
