I don't think it is as popular here, as you say. In my opinion currently none is, with the exception maybe being the GL2760H (*) that has multiple user reports. However it is very bright. That one not included, I have tried several BenQs now and almost all were pretty much unusable. Only the EW2440L at very low brightness has been usable for longer periods of time. But the bigger model, EW2740L, is truly outstanding, at least for me and provided the input signal is "usable". Maybe you can still find one and try it (it is already hard to get).
You say you use Windows 10 on the latest update. Some of us, at least Gurm and me, have reported Windows 10 has become unusable for us after a certain update.
Or maybe it is your graphics card or its drivers, and maybe on top of the other problems.
You may want to try to isolate the problem based on this info.
What you can also do is try to connect another known-good device to the monitor and see if there is any difference.
(*) Not sure if this is the right model, I tried to search for it but it is hard to search and find anything in the forum
