I agree with this comment if the person is trained to see those artifacts. Most folks are not, so no matter the screen size - they can miss even the obvious artifacts on any size screen.
If this is the limit of your exposure (or space), this is the limit of your perspective. My focus was not on 65 to 75" panels, that would be FAR, FAR, FAR too small for the rooms we are shooting for. I am talking about screens twice the size of what you suggest in rooms much larger than a 65 or 75" panel can support. Context and detail are more important than blanket statements without either. I attended a demonstration of the Christie Eclipse projector on a 200" screen, and no panel on this planet could keep up with that. It is approved for DV, can get FAR brighter than any panel, can produce blacks as dark as a QD-OLED, and can produce 100% of both the P3 colorspace and the BT.2020 colorspace. Exposure to something more than a panel is important here, and no panel can do what this projector can.
This is a prime example of a hyperbolic statement (which shows a profound lack of understanding of screen size and resolution vs proper viewing distance) with no grounds in reality. Who in their logical right mind would sit 3 feet away from a 200" screen? Please, do better than this so you do insult anyone's intelligence.
