I have E3-1225 v5 with HD P530 IGPU, and my system is macOS Monterey. My monitor is an LG 27UL550, which normally runs at 4K@60Hz. I spoofed Skylake as Kaby Lake and successfully installed macOS Sequoia, but I encountered an issue: the screen randomly goes black for 1-2 seconds, similar to what @NumberVII and @corpGibbron experienced.

I tried many ways to fix this problem, and eventually, I found that lowering the resolution to 4K@30Hz or even lower prevents the black screen issue. However, this significantly affects the user experience. As a last resort, I had to revert to macOS Monterey.

By the way, I'm using a DP connection for my monitor. Is there any other possible solution?

Can you attach the config.plist?

Also, is there any option to change the DVMT values in BIOS?

I used the modGRUBShell tool to modify the DVMT value in the BIOS. The initial configuration is as follows:


but after changing the DVMT pre-alloc value to 128MB, there seems to be no effect. Below is the content of my config.plist file
