I had such a problem. When Windows sends monitors to sleep state or monitor is powered off, monitors on DisplayPort connections send hot-plug event and are removed from the system. Windows then moves windows and icons onto remaining monitors.
NVIDIA firmware update [0] solved the problem for me. It seems they ditched the naughty part of DisplayPort standard for good and stopped passing hot-plug events to OS.

- fdkz 7y agoThis did not help in my case. I have 3 DisplayPort 1.2 monitors, and half of the open windows get still tossed around randomly when the monitors wake from sleep, or when the whole PC wakes from sleep.
- HeWhoLurksLate 7y agoI'm in the same boat with my Dell P2210t- it's DisplayPort connection "disconnects" the screen, which is really annoying when you're trying to operate remotely and your config doesn't match its anymore.
- velosol 7y agoA couple years ago the other option was to dump the EDID of the connected monitor (while it was on of course) using Nvidia's display software and then set the EDID data using the same software (overriding the EDID which would apparently get cleared when the monitor sent its hotplug event). If you ever actually removed the monitor you'd have to go remove the EDID data.
