Shouldn't lose windows then as it's just extending your current 4k TV. ]]> https://www.displayfusion.com/Discussions/View/can-i-effectively-disable-a-second-monitor/?ID=dad723af-0432-43ba-88c4-2ba1e552a78c#2 Thu, 06 Sep 2018 00:21:39 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/can-i-effectively-disable-a-second-monitor/?ID=dad723af-0432-43ba-88c4-2ba1e552a78c#2 DisplayFusion There isn't really a way to "virtually" disable the monitor, unfortunately. What you could do is assign a key combination to the "Move all windows to current monitor" function on the Settings > Functions tab. After exiting your game, if there are windows stuck on the non-existent monitor, you can press the key combo to move them all back to the monitor that the mouse cursor is on.

Hope that helps! ]]> https://www.displayfusion.com/Discussions/View/can-i-effectively-disable-a-second-monitor/?ID=dad723af-0432-43ba-88c4-2ba1e552a78c Mon, 03 Sep 2018 18:16:41 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/can-i-effectively-disable-a-second-monitor/?ID=dad723af-0432-43ba-88c4-2ba1e552a78c DisplayFusion Ok, so I have something of a wierd set up. I bought a 4k TV and needed to get a DisplayPort to HDMI adapter to be able to run 4k@60hz. Unfortunately, MSI's displayports don't allow 7.1 channel audio over display port, which means I have to run an HDMI cable to the reciever, purely for the purposes of audio.

SInce running audio over hdmi requires video, I'm stuck with a second monitor that I can't see and occasionally lose windows too.

The biggest problem is that if I run a game at 1920x1080, than Windows moves a lot of the windows to the second monitor. And it's hard to get them back.

Things I've done:
On startup lock cursor to current monitor.
On window create: move to Monitor 2
On window restore: move to Monitor 2

Those help a little bit, but they don't seem reliable and I still lose windows to other monitor.

I was wondering if anyone had any advice on how else I could resolve this?
Thanks! ]]>
