Hello, thank you in advance!
Source is PC with 1 hdmi to splitter > capture card > pi > leds. I Also use splitter to go direct to TV. This works no issue.
Where I run into an issue is if I connect an extra DP output from my PC to a monitor. Windows then sees 2 displays (monitor is 2k ultrawide and hdmi splitter 4k downscale to 1080p); and the lights just show on the left & right sides.
Swirl effect still works np and confirmed all layout is working, and that root issue is somewhere in capture card area.
Anyway, if I duplicate the displays and set resolution to 1080p,the lights work around the entire TV (but of course my monitor is wrong this way).
-- I'm confused where the root issue is because splitter should be sending correct resolution to capture card regardless of an extra monitor connected to my PC
