Bigbox 4th Monitor

[JohnRofls]

My computer set-up is 3 main 4k desktops and 1 1080p TV. I want to launch bigbox on the 4th montior.

Bigbox sees 4 displays but renders the content of the interface on the primary monitor (display 2 according to bigbox) when display 4 is selected.

Some additional relevant details:

I had 150% display scaling set on monitors 1 - 3 and on monitor 4 I have 100% display scaling.

Setting monitor 4 to the same display scaling as monitors 1 - 3 simply changes the size that bigbox renders the window when displaying on display 2 even though display 4 is selected.

---

Interestingly when I set all 4 monitors to 100% display scaling, bigbox does display appropriately on the 4th monitor. With all monitors set to 150%, it displays fine on 3 of the 4 monitors when toggling but still not the 4th monitor. 4k monitors with no display scaling isn't really usable so I'd love to resolve this so I can keep my primary monitors at 150% display scaling. I don't mind whether the 4th monitor (TV) has to be at 100 or 150% display scaling. Either works for me.

Based on this behavior, I believe this is just a minor math error that's impacting where bigbox displays when a 4th montior is invovled. Can anyone else replicate this issue? Should I submit as a bug?

 

Follow-up: When I set the display scaling back to 150% on the 3 main montiors, bigbox stays positioned where it is. However upon re-launch or toggling through the display positions, it will go back to it's position on the 2nd montior rather than on the 4th monitor when display 4 is selected.

This would further lead me to believe it's a very minor bug in the logic for determining where it should render. It's as if there's just a few scenarios where it doesn't take into account display scaling pixel position. Hopefully this helps.

Additional follow-up: 

To clarify - Bigbox sees 4 displays. 2 of the 4 displays end up displaying the image on the primary display. None of the options display on the 4th monitor.

However, I have confirmed that setting the 4th monitor as the primary monitor will allow bigbox to display on it. In this scenario 2 of the 4 display options display to the 4th monitor and one of the other main displays is excluded. Unfortunately setting the 4th display to the primary monitor is not ideal as I have to revert this setting frequently. I'm trying to create a batch file to toggle this as part of a big-box launcher batch, but this is still a work-around for a bug. Albeit, I realize a non-unique situation of having 4 monitors.
