Sadly I have the same screen issue. This is it, I have reached the end of the line with my Surface Pro 4, or any other surface device. I'm not buying surface ever again. Beautiful device and specs are quite decent, did well by me for 2 years. Then the microsoft type cover stopped working, and after much hassle I ended buying another brand's bluetooth keyboard that is working until today. Then the battery started to act funny, wouldn't hold a charge, would last less than an hour and would deplete even after complete shutdown. After a few updates it got better, though battery performance never went back to optimal. Now this screen issue just showed up, which I thought would be fixable in some way, but it seems its the final death sentence to my device.
This is supposed to be a premium device
