My Surface Pro 4 screen started shaking on Wednesday, 21st March 2018. Over the past two days, the issue has developed from a slight 'blur' to a visible shaking of the screen, and it usually starts within 5 seconds of my inactivity - i.e. after I stop moving the mouse or typing.
On a rare occasion, the screen works just fine. For instance, Task Manager's pop-up window seems to 'prevent' the screen shaking, and I think I remember other pop-up windows having the same beneficial effect -- which is strange for a 'hardware issue', isn't it?
Having read several user reports on their failed attempts to rectify the issue, I decided not to go into trouble of reinstalling Windows or Intel display driver. All I'm hearing is 'hardware issue', so why bother playing with software?
My Surface Pro 4 with Intel Core i5-6300U and 8GB RAM is running Windows 10 64-bit.
On an average day, I probably use my Surface for 3-4 hours. I keep it on 'Best Performance' setting when plugged in, and on 'Recommended' setting (like 33%, or second 'notch' from the left) when on battery power.
