So I just ran into this problem and noticed that my laptop updated while asleep and stopped connecting to my external monitors. When I reconnected (unplug dock from USB and plug it back in), I got a message about letting windows adjust screen resolution.
I clicked out of it and didn't think anything of it as I've never needed to do anything like that before.
Since I had this problem I was playing around with the display settings and found the below to work. I have a Dell laptop running windows 10.
Close out of InDesign-->Right click on the desktop and choose display settings--> scroll down to 'Scale and layout' and underneath the (possibly grayed out) dropdown menu labeled, 'Change the size of text, apps, and other items' click on 'Advanced scaling settings--> in here, turn on the toggle button for, 'Let Windows try to fix apps so they're not blurry'
That's all I did and fortunately it worked for me. Good luck.
