Bigbox Marquee on Wireless Secondary Display?

[Prick Slickfield]

So I repurposed an old tablet to be used as a wireless secondary display in Windows using Spacedesk, with my primary screen being a 55" 4K TV. However I'm not able to get the marquee screen in Bigbox to show up on the tablet display. When I alt tab I can see the marquee window open on the primary screen but I'm not able to click into it and drag it to the secondary display, nor can I use the Windows key + Shift + cursor key combo to send it to that display. Has anyone tried this setup and what settings do I need to adjust so BigBox recognizes and uses the second display as a marquee screen? The tablet resolution is only 1280x800 so i wonder if that's an issue. Is there an XML file somewhere I need to edit?

Thanks

In BigBox make sure you have set your primary and secondary screens and I believe BB needs to see the monitor the same way Windows would recognize it. I am not sure if it will work through a 3rd party program like SpaceDesk. I could be wrong.

Primary and Secondary screens are set in BB (Screen 1 and 2) so it's def recognizing it. It's working with other programs - in Cemu for example I'm able to set the tablet display as the Wii U gamepad screen which is pretty cool. I'll keep messing with it, maybe try a different virtual display app.

Problem solved - ended up messing with the DPI settings in BB properties. Tick both boxes for Program DPI and High DPI scaling override, and select System the dropdown. This was a very productive 7 1/2 hours of my life.
