Annoying application window resizing after sleep

[Vicljh]

I use a host + monitor. Whenever I wake up the computer after a period of sleep, the application windows on the desktop will all become smaller and concentrated in the upper left corner of the monitor, which is very annoying. I have searched for many solutions, but still can't solve it. I guess the root cause is that Windows disconnects the monitor after sleep, and when it connects again, it first connects to this 640*480 virtual monitor. I deleted the virtual monitor, but it automatically appears every time after sleep. The virtual monitor is created by the Intel graphics driver. I hope Intel can provide technical support to improve this problem.

I am using a 13th Gen Intel® Core™ i7-13620H processor with Intel® UHD Graphics.

Hello Vicljh,

If the Displays are turned off when the computer goes to Sleep (also known as S3 or Standby) and then switch them ON again all the opened windows are resized and possibly moved across or between available Displays.

Intel has concluded that this situation occurs due to an Operating System (OS) design. The OS is not storing and persisting the window size and placement upon the disconnection of some display devices. Our driver is reporting a plug event correctly to the OS, but without persistence windows shift and move to the primary display. Other manufacturers may work around this through their own driver implementations.

Intel recommends reporting this issue directly to Microsoft.
