I've got a laptop with a UHD display connected via a USB3 dock to a normal monitor with Full HD. This runs Windows 10 professional.
I seem to have a bit of a problem between the scaling of items between the two monitors. Sometimes (but not all the time), icons and displays will get confused as to what monitor it's running on.
To explain this, desktop icons on the FHD display sometimes are scaled at 200%, and other times the icons the UHD display display at 100%. Additionally, certain windows and texts are blurry, almost like they are being scaled up/down and then reduce/enlarged to properly match the display.
I've also attached an image of what sometimes happens when moving between monitors. In this case, I'm moving a window from the UHD display to to the FHD display, and during the time when it crosses both windows, it appears on the larger of the two monitors at 200%, and remains this way until the window has been completely enclosed by the FHD monitor (at which point scales down to 100%).
Does anyone have any suggestions about how to fix this?
