Does anyone have a link to the 1080p version if this is something that even exists? I only have a link to the 4K version which I cannot play on my TV
As far as I know, a 1080p-Version does not exist. Your only option is to convert the video file. Maybe try to convert to different codec (H264)? The 4k-Version uses HVEC/H265 which not all TVs/Players support.
