I’ve noticed that some files I play via Infuse (on a Sony laser projector) will show blocky/pixillation, usually in dark areas. (Attached photo exaggerates this a bit, but hopefullly you get the idea).
I’m curious – is this just a compression artifact (file type .mkv)? This doesn’t happen on every mkv file – most look great. Alternatively, does it have something to do with the projector or the AppleTV 4k?
