I finally upgraded my monitor this week and I'm suddenly coming across some weird issues with Opencore. Firstly Opencore now boots in a really low resolution (the new monitor is 4K). My first thought is that it's using the resolution from my old monitor which was 1080p, but I don't even think that's it because it looks even lower. I've already tried resetting NVRAM to no avail and both UI scales, but neither was correct. Had a look through BIOS settings as well but can’t really find anything.
Another thing that now happens is that I lose signal during macOS boot. I've managed to get around this by simply unplugging and reinserting the DP cable, and then I'm greeted by the lock screen but not ideal - any ideas why this might be?
A bit of background - I'm currently only using the iGPU (with wegnoegpu), as the only graphics card I've managed to procure is from Nvidia and I have a sneaking suspicion this has something to do with it. I also get the occasional stutter during use, but I can't tell if this is an unrelated mouse connectivity issue or the iGPU struggling with 4K - just thought I'd mention it just in case.
Any help much appreciated!
