Game changes screens on me

I use duel monitors, my main (#1) is a 45" widescreen monitor and my secondary (#2) is a 32" monitor. I was playing SWJ Survivor on my main the other night everything was fine. The next day I was playing the game and all of a sudden it switches to my #2 monitor WTF? I have tried everything I can think of to get it back to my main (#1) screen but nothing works. I cant find anywhere in game were I can choose which monitor to play on. I have also tried putting it into windows mode and dragging it back to the main screen. But when I release it it ALWAYS jumps back to screen #2.
Any Ideas?

When things like that happen to me, I try to find info via Tom’s Hardware which is a site that actually helps folks with electronics and issues they have. I’ve used them for years for so many different things and they have always been helpful.

Just type in Tom’s Hardware?

Here’s the link for you: https://www.tomshardware.com/

Can you turn off the second monitor and then start the game and see if it shows up in primary screen. If that works, can you then turn on the second screen and see if it jumps back.

Also check the connections to your primary monitor, since Windows tends to switch it’s “primary” display when a connection fails, depending on what kind of connection it has. (DP vs HDMI have very different reactions)

And the “failure” can be anything from a video driver crash, to a millisecond disruption to a signal due to a cable being somewhat wonky.
