Recently all videos I watch from my server that are h.624 feature this nifty new green line at the bottom of the video. This only happens when watching a video on Plex and not any other game/app. I have the ps5 plugged directly into my LG C1.
Things I have tried thus far:
change ports
change HDMI cord
reboot Plex server
force ps5 to play at lower resolution (1080p/720p)
I’ve seen this. Sometimes its on the bottom and sometimes on the right or left sides if the video aspect is letterbox.
As a test try and disable both direct stream and direct play on the plex for playstation app. I’ve found that the ONLY way to get decent playback using a ps4/ps5 is to disable these forcing plex to transcode. Not great but works.
I’d started a discussion a while ago on this but it was auto closed after being ignored. Since disabling the above we’ve not had any playback problem, including this green line.
