About a few days ago, the screen on my Surface Pro 4 started intermittently looking like it was 'vibrating'. That is, the images on the screen, including lines, pictures, and text, seem to be moving or duplicate just a pixel or two to the top/bottom.

What is an inclined vibrating screen? Inclined vibrating screens have no horizontal layers, being designed at a certain angle. The screen sits on springs mounted at the four corners of the chassis. The screen body is driven by the vibration system. For which processes/applications are inclined vibrating screens used?

The vibrating screen is driven by a vibrating motor. The frequency of vibration depends on the speed of the vibration motor. The speed of the vibrating screen is reduced, or the reduction ratio of the transmission system is increased. Large, can reduce the vibration frequency of the vibrating screen.

The image on my screen is vibrating/shaking/scrolling up and down very quickly about 1 mm. It's the whole image (including the taskbar) which moves up and down. The problem is not isolated to a particular app. It seems to affect everything - also e.g. task manager and the screen clip application, which usually freezes the image.
