2 Monitors, PUBG switches to secondary Monitor after loading.

[M3SA]

Just as the title suggests, I have 2 monitors same resolutions. 1920x1080.
When I start the game it is on the correct one, then after the splash Logos disappear it moves to my secondary monitor..
Ive already made sure the monitor in Windows is the "primary". Ive used Win+Shift+ --> arrow to move it to the correct one but after you start a match it switches again to the other non default monitor, after match ends. Its tedious..

HDMI is plugged from primary to GTX1080
DVI is plugged from secondary to GTX1080
I have to unplug or disable the secondary to get this game to work right.(obviously)
Ive read recently people think it may be something with the Unreal Engine and or Windows 10. Or both..
I just today got a displayport cable in hopes that it will look to that as the primary in PUBG, but it didnt change anything.(worked for others I guess)
I literally hate this game only because of this issue.

in a nutshell ive tried...
-Deleting TSL config file
-Reinstalling
-Trying different Cables
-Updated my ASUS Monitor Firmware so it shows the name in Windows, instead of 'Generic PNP' monitor.(or whatever it says)
-Borderless Fullscreen Force to primary

This also happened after a patch probably in Feb '18, so im feeling like its on the game side more than Windows. All my other games(roughly 50) work ok. The ONLY other game that is doing something like this is Last Year: The Nightmare, which is where i scratch my head and think maybe it does have somethign to do with Windows or games using Unreal Engine.

If anyone has any Ideas please share. Thanks
