I have a 3 monitor setup, I use the center monitor as my Main / Default Monitor, I have all my streaming stuff on my right monitor and web browser / other crap on the left side with the task bar. Every other Game I have launches on the Middle / Default Monitor automatically by default every time without a Issue except Arma 3, it keeps launching on my left monitor, monitor # 3. I haven't figure out a way to change / fix it yet.
Thanks.
Launching the game it is as simple as that
ive tried putting the game down to window mode and dragging it to the middle monitor and then making it full screen / full screen windowed again but it just goes back to the left monitor by itself once it changes to full screen or full screen windowed.
I am having the exact same issue. Odd side note: yesterday it worked fine this problem only started today.
