So, there’s a bug with the graphics drivers at work, where if the 4K displays go to sleep, all the windows are on the primary display when I get back to the computer. It’s super annoying, but nothing worked to stop it.

In the end, I bought a little gadget that stops the display from going to sleep. It is a small USB device that moves the mouse 1 pixel every 10 seconds. While it solved my problem, it is designed for your exact use case: amzn.asia/d/cyeA6qH

It presents as a USB mouse to the computer, doesn’t need any software. It keeps you “available” all day. Just thought you might like to know it exists. 😉
