<< Solved >> How to enable 4K on i3 8100T with DVMT 32mb in Mojave 10.14.6

[fungcie]

My system is dell optiplex 3060 i3 8100T with single channel 8 gb memory and 500 gb samsung evo pro 970 ssd. It suffers from DVMT setting that is fixed to 32mb.

I already fix all the igpu problem and everything is working normally, including graphics acceleration. But what ever I do the highest resolution is 2560 x 1440 pixel. I already insert the enable-hdmi20 to enable 4k without any luck.

Can anybody help me with this?

Don't mind about my stupid question. To have 4k res you have to edit DVMT pre allocation in the bios. You can find it somewhere in the forum.
