Game appears on wrong monitor

[Cynicide]

This game constantly opens on my second monitor, I've checked Windows and:

My primary monitor is set as my main
My primary monitor is monitor number 1

Things I've tried:

Going into windows mode and dragging the screen to my primary monitor then fullscreening... no good.

Running windowed... no good, my mosue often moves outside the window and clicks things on my desktop.

Using the Windows + Shift + Arrow key to move the window... no good.

Any ideas?

Somewhat of a solution here, but not a great one. Look at xmak's post from Nov' 2019 here: https://forums.unrealengine.com/t/start-game-on-particular-monitor/69483/4

You need to tell Unreal what the first pixel of your main monitor is. Because I have a 1680 x 1050 secondary monitor to the left of my main monitor I had to add -WinX=1680 to the command line. This number will be different for you based on where your monitor is located in relation to your main monitor. I also had to set the game to Fullscreen and click the Settings button once I was in the game.

Go to your game's launch settings in Steam and type -fullscreen. Your game should start in Fullscreen on whichever display is marked 1

@Cyanicide Did this solution (using -WinX=-1920) actually work for you? It seems to not do anything no matter how I type it.
