Hi, I have recently upgraded from a Surface Pro 3 i5 to the new 4, and just wanted to see if anyone else was experiencing a similar screen issue. The screen has a couple dark patches left and right that start from the outside edge and run vertically too the top. You only notice on a light colour/white background, and it could be due to the speaker placement applying pressure to the screen. Didn't notice anything similar on my previous Surface Pro 3. I have attached an mockup image of the issue. Everything else about the unit is good, so a little apprehensive about changing for a unit that could be worse. Thanks.
