I think 4k home media is largely a waste. For most titles, DVD is still good.
I read those two things and decided not to read on.
Most movies weren’t made with such detail in mind. Most don’t need that level of detail to tell the story. New movies look great in 1080p, but 720p for HD broadcast for fine for most. For those who sit far across room from the screen and are more interested in the story, 480p is plenty. I still watch DVD’s And I don’t bother with Blu-ray from Netflix. Now a movie like Interstellar… that is a Blu-ray movie. When you watch for the visuals then more pixels becomes important. Vital. I’d love to see Lawrence of Arabia in a 4k or higher projection. But for the latest comedy or a typical silver screen classic… DVD works.
