i've seen a lot of similar queries about this issue but no actual fix, and i thought i'd seek my own answers about it. i've had my surface pro 4 for a little less than 2 years now and suddenly a dead strip has appeared horizontally across the screen. the mouse works fine in it but it doesn't register any input from pen or touch and i'm curious if it's actually a hardware issue or something to do with drivers or software? i updated all my drivers one time and suddenly it was fixed for a whole of 5 minutes before the strip went dead all over again, and now nothing seems to fix it but i haven't wiped my device yet like i've seen with others because nobody actually confirmed that it works. here is a demonstration of the dead strip, i used paint tool sai for this one i looked into it and servicing my device would cost just as much as buying a whole new one, so i'm not really a fan of that solution. if anyone has some idea other than servicing it, i'd love to hear, and thank you.
