I noticed a strange issue with my new Philips Brilliance 242B7 (23.8") monitor: more or less every 5 minutes, the image moves 2 pixels vertically or horizontally.
The problem is that when the image moves, the border in that direction is cut off by 2 pixels.
Here's some picture (taken obviously with a smartphone, since a screenshot from the OS wouldn't show the issue).
Lower border normal:

Upper border normal:

Left border normal (this is an icon left-aligned on the desktop):
Left border cut:
Switching the monitor off and on again solves (temporarily) the problem.
There is no "adjust picture" or similar option in the monitor settings that I could try to use.
The monitor is set to 2560×1440 (native resolution) and is connected to the computer via DisplayPort. The computer has a NVIDIA GeForce GTX 1080 graphic card.
I run Windows 10 Home, and here's is a post from a Mac user having the same issue on a Philip Brilliance 258B6QJEB monitor: http://www.insanelymac.com/forum/topic/315894-weird-issue-with-my-gpu-or-monitor-image-moving-1-px/
What could be the cause and how to fix it?

Based on nothing more than an educated guess - & not remembering the actual technical term of it initially - this would appear to be a hardware feature of the screen itself...
Pixel Orbiting.
A screen-saver mechanism intended to prevent burn-in on static images.
It's accessed via the OSD according to the manual, page 8 - available from Philips https://www.download.p4c.philips.com/files/2/242b7qpteb_00/242b7qpteb_00_dfu_eng.pdf
