for -severe- problems i have a laptop setup that works perfectly for me (who otherwise isnt able to use almost any modern device)
but note that it has a rather unique way of getting the software aspect of it working that will lead to a different workflow you'll have to get used to. (using the laptop as a VNC thin client that connects to another device in the same house)
but it's the only setup i've found that's both easily reproducible and actually managed to create a real, consistently working solution to my severe screen sensitivity
i can dm you about it if you want to know my exact setup
for starters, the hardware needed is Lenovo ThinkPad T480 8th gen intel ($240 or less!) and the replacement LCD panel (required) is AUO B140XTN02.D (find a used or open-box one on eBay for $50)
however, it also needs a certain software/OS configuration to get this hardware to work perfectly (i.e. can work for 11 hours straight with zero tiredness and zero issues reading). way better on the eyes than e.g. simply installing Windows 10 onto this hardware. this is what i can dm you about if you feel like nothing else has worked for you
