mirza Let's try to make booting more verbose by adding the -v parameter
Please, try to input
sudo nvram boot-args="-v enableDither=0 PE_i_can_has_debugger=1 iomfb_RuntimeProperty_enableDither=0"
Then make sure the boot-args was accepted:
nvram -p | grep "boot-args"
The output must be the same as the previous input.
Reboot your laptop.
run the command
log show --process 0 | grep "IOMobileFramebufferLegacy"
Same issues unfortunately. And, just to be on a clear side, I'm pluggin my external monitor back and forth with PC and MBA, while closing MBA, just to make sure. For hours I'm using my Benq without any issues, in fact feels relaxing on the eyes, I plug it to MBA, wait 5 mins or so, eyes start to burn a bit, light headache, and whole nine yards. But please, do keep trying Maybe you will be the one to solve hundreds or thousands of people's issues. I mean, it has to be software issue, otherwise it doesn't make sense from this I wrote above…
I read somewhere (I think macroumors) that temporal dithering is not used at all on macbook air m1… Is that a possibllity? Then what is generating this problem?
sorry lost it, how to write it?

mirza If you really use macOS ventura, it explains the weird things I noticed (you don't have any mentions of 'IOMobileFramebufferLegacy' in the kernel log).
The macOS Ventura changed concept of using of the kernel extensions. I don't familiar with the technical details.
The folder you dropped just doesn't have the drivers which existed on the previous macOS versions.
