CORE SYSTEM:
- Intel Core i7-4790 3,6 GHz
- 8 GB RAM
- Windows 8.1 (latest Updates)
GRAPHICS AND MONITORS:
- Intel HD Graphics 4600 - Latest Intel Driver (16.3.2015, Version 10.18.14.4170)
- Main Screen: ASUS PB287Q - 4K (3840 x 2160)
- 2nd Screen: ASUS VS24A (1920x1200)
PROBLEM:
When the monitor is waked up from energy saving mode, then all movements on the 4K monitor are "lagging behind". The mouse cursor feels slow, like being "sticky". Dragging a window is slow, and during movement, windows also appear as being split into two halves.
I don't know the exact reason, but possibly the refresh rate is out of sync.
EDIT: The OSD of the monitor says that it is always running on 60Hz.
CURRENT SOLUTION:
Monitor needs to be turned off and on again, then it works. Seems like the driver is getting a refreshment signal due to monitor power-off-on.
EDIT: It also works when doing some change on the driver, e.g. turn the picture left, then back again. So in fact it is a software/driver problem.
QUESTIONS:
- Can the driver be configured that the lagging problem does not happen?
- If that is not possible, is there at least some command or shortcut which resets the driver, like it does after turning off and on the monitor ?
