I have a very slow Internet connection (5 Mbps down, and even less for upload). Given that, I always download movies at 720p, since they have low file size, which means I can download them more quickly. Also, I don’t notice much of a difference between 1080p and 720p. As for 4K, because I don’t have a screen that can display 4K, I consider it to be one of the biggest disk space wasters.
Am I the only one who has this opinion?
Completely true, but also compression can make anything bad. I’ve seen 480p better 1080p simply because the 480p was using more bitrate, where the 1080p is encoded without enough relatively speaking.
Yes, resolution is not the only factor. Bitrate is equally if not more important.
