Microsoft Windows 10 will soon benefit from a patch that fixes the behavior of screens when they wake up. Users complain that the operating system messes up by putting all the windows on one screen. The fix is already available for Insiders.
Some erratic Windows 10 behavior can be frustrating. Among these problems one of the most annoying is undoubtedly what happens with when waking up from sleep with certain external screens. Imagine, you are working on a complicated project, and to facilitate your work, you have organized in a clear and hierarchical way on two screens some fifty web pages. You then take a short coffee break. When you return, the computer is on standby.
You move the mouse and there, horror: Windows 10 decided to paste all windows on one screen. All your efforts go down the drain and you have to start over, disabling standby for safety first … Many Windows 10 users have been complaining about this erratic behavior for some time. And it seems that Microsoft is finally determined to tackle the problem head on. In the latest Insiders builds (21287 and later) your windows now always stay in place regardless of the screen when you wake up.
Microsoft Windows 10 finally fixes the bug that displays windows anywhere when waking up with external screens
Microsoft is expected to push the change to more machines by the end of 2021. On its blog Microsoft explains that the problem only occurs when the external display is connected with a DisplayPort cable rather than HDMI. The bug is related to a feature known as Rapid Hot Plug Detect (Rapid HPD). In the meantime, if you find the situation on your machine too frustrating, there are two options available to you.
The easiest way is to replace the DisplayPort connection with an HDMI connection when possible.. Obviously some will see this as a regression: DisplayPort is much more versatile than HDMI cables. It is possible to connect several monitors “in daisy-chain” – moreover DisplayPort is compatible with technologies like FreeSync from AMD and G-Sync from Nvidia which avoid graphic artefacts at high resolutions.
You can also join the Insider program to install a newer build. Note, however, that it is not recommended to do this on machines that you use every day in the course of your work. Indeed, it is possible that the Insider version of Windows 10 fixes the display problem, while causing other problems elsewhere.
