Re-detect display devices keyboard shortcut causes black screen.

I've tried searching the forums and the web but haven't found a solution to my problem. :(

Whenever I click the keyboard shortcut super+P (The default for Re-detect display devices); my screen goes blank, and I get a "no signal detected" message on my monitor. If I press the shortcut again, the screen turns on again and everything starts working as normal.

This wouldn't be much of an issue, if it also didn't happen directly after boot/login. Whenever I restart my computer, the screen goes blank directly after login (I have auto login enabled as this is a HTPC) and I have to press the key combination.

This issue strangely appeared when I accidentally pressed the shortcut once by mistake due to my keyboard having this shortcut pre-programmed as a custom button (Pressing the custom button sends a super+P combination to the computer). In that situation, I just pressed the button again and didn't think more of it, until next time I rebooted the computer and the screen went black again.

Anyone having any ideas why this is happening?

Thanks :)
