I have setup LaunchBox BigBox 7.0-beta-15 on Windows 10 Anniversary Edition 64-bit. My GPU is a GTX 980ti.
The marque is set to display on monitor 1 and the BigBox interface on monitor 2. The BigBox UI shows fine on monitor 2, but the marquee seems to also be on monitor 2 but hidden behind the BigBox UI. Monitor 1 just shows a picture of my desktop. You can see the marquee in the Marquee and BigBox.png below. That screen shot shows that the marquee displays in the alt-tab menu.
Some other details. If I change BigBox to show the UI on monitor 1, it just resizes it instead of resizing it a moving it to monitor 1. Monitor 2 is my primary display in display settings. Monitor 2 is also 4k and I use 150% DPI scaling. Monitor 1 is 1080p and does not use DPI scaling.
Any assistance would be greatly appreciated.
