I have a pretty elaborate setup and I get if this isn’t the highest priority in the world for you guys… but this may be affecting others and I’m happy to help troubleshoot.
I have 4 monitors. 3x 1920×1200’s with a 4K TV centered above (occasionally on) hooked upto a single GTX 980 Ti. I like to get as much text on the screens as I can comfortably read, so the ‘Change the size of text, apps, and other items’ option in display properties is set to 100% for monitors 1, 2, and 3 (1920×1200’s) and 150% for monitor 4. With this setting, the size of things is consistent and the resolution on the 4K screen looks as though I have 4x 1920×1080 screens at 100% (hope this makes sense).
What I have typically done in the non-UWP versions was use WIN+SHIFT+LEFT/RIGHT to move Kodi to different screens. In the non-UWP version, when I moved from a 1920×1080@100% DPI to a 3840×2160@150% DPI, the Kodi UI would adapt and everything was nice and easy. In the UWP version, when I move the app onto the 4K/150% DPI screen, I see the this:
If that’s not rendering correctly… I see the top left corner of Kodi on the top 4K screen over-zoomed.
… and the rest of the interface, over-zoomed (@150%) spanning pieces of the bottom 3 screens (starting 80% across screen #1 and extending beyond screen #3). I can’t see the top-right corner of the UI at all as the interface is over-zoomed.
The problem exists even without WIN+SHIFT+LEFT/RIGHT… Anytime I try to set the Dispaly Mode to Full Screen #4, it automatically goes to 3840x2160p and I’m over-zooedm.
