Alternative title: Does 900p vs. 1080p Really Matter?
They all agreed on that, so I went with the title "The naked eye cannot perceive a difference between 1080 and 720 before 50 inches"
(I was prompted to include that this was said on their Xbox Podcast)
If anyone has the names of these guys, I will fill them in. Updated.
The first question on anyone's mind when it comes to perception and resolution on such a statement is? "At what distance?"
It's a pretty definite statement being made, but it's incomplete.
The assumption in here is probably average human visual acuity, so I'm not going to be pedantic about that and use perfect visual acuity the way 4K proponents use. (0.6 arcmin, but rather 1 arcmin which US citizens know as 20/20 vision.)
Edit:
According to carltonbale.com whose resolution chart I think is the best when it comes to this topic as it deals with 20/20 visual acuity says the following:
You need to sit 4 feet (1.22 meters) or closer at 27"
You need to sit 7 feet (2.13 meters) or closer at 50"
This is when we're talking about film though, which is not 100% analogous to games, because of the aliasing inherent in games. Movies have an "automatic" anti-aliasing built-in because of the quality level they are recorded and then mastered.

Destin Legarie said:I think you need a TV that is larger than 27 inches to even take advantage of 1080
Ryan McCaffrey said:Oh, more than that.
Mitch Dyer said:The naked eye can not perceive a difference between 1080 and 720 before 50 inches
Ryan McCaffrey said:Exactly - That's what I heard. That's my understanding as well.
Destin Legarie said:So it doesn't even matter because your TV can't even handle it.

Alright, fine, let's do some optics calculations.
I'm sorry, IGN, but you'll need to retake this class. I'll be giving the lectures, and I'm requiring you to sit an additional 10.171 feet away from the whiteboard.
- A 50" screen with a 16:9 aspect ratio is about 43.579 inches (1.112m) wide by 24.513 (0.623m) tall.
- At 1920x1080, the pixels would be 0.0227 inches (0.579mm) wide and tall. At 1280x720, they're 0.034 inches. (0.864mm)
- The typical resolution for a human eye with 20/20 vision is about 2 arcminutes per line pair.
- This means a feature is no longer resolvable when it's 10,801 times further away from the eye than it is tall/wide. (2 arcminutes / 360 degrees = 10801.08)
- On a 50" display with a 1080p resolution, individual pixels can no longer be resolved if the viewer is 20.432 feet (6.228m) away from the screen. For the same display at 720p, it's 30.603 feet (9.328m).
