So Ive noticed that the industry standard for image resolution for photos from paysites these days seems to be around 8000 X 5000 pixels. Which usually brings the size of the image somewhere around 8MB which is high compared to just a few years ago. I know these images could be half that resolution or even lower and I wouldn't notice a difference on my 50 inch 720p t.v. Im wondering what the max image resolution needs to be for an image to register well on a 65 inch 4k t.v. ? Anybody know?
