There are 4 identical Android TVs. The SpaceDesk server sees them, but does not collect them into one video wall. TV resolution 1920×1080, video wall 2×2, video wall resolution 3840×2160. I don’t understand what the problem could be. USB didn’t work at all, not 2.0 not 3.0. Windows sees a 3840×1920 screen, but the TV only displays the desktop, each TV gives the same picture.
