zlhr If you think that disabling DWM theme and using classic mode will help you, I maybe have a possible solution for you.
Someone figured out how to make a "true" classic theme working and usable in windows 10 and made a program to simplify things:

Keep in mind that in requires .NET 5 redist and might or might not completely disable DWM
I'm a long time member of that board but with a different username
There are 2 methods to get "classic mode" on Win 10, one is winlogin based which doesn't help as it retains DWM, the other is to eliminates DWM but this results in an unstable system
I am trying the Dasung 13.3 inch einkmonitor right now, it's only been an hour or so but it seems decent. It is annoying to use being so small and grayscale, they have a 23 inch version releasing this year though. I'm going to give it a week. I am also going to try a new BenQ monitor any specific model recommendations?
