Except that would only make it more noticeable. Plus, the HD football game i was watching looked very good. I did not see any compression artifacts. What it comes down to plain and simple is that the chart is wrong. Myself and several other have noted that there is a VERY LARGE difference between SD and HD content at 15 feet on a 42in TV. With that chart i should not even be able to see 720p much less 1080 and yet i clearly could.

I've noticed this as well...THX has similar screen requirements, but they gear it more towards "the fulfillment of the theatre experience" So they more or less say that at a certain SIZE and DISTANCE, the screen will fill your vision closely to a movie theatre screen.

These graphs that say you don't discern any difference in quality are interesting...because I wonder if they just sort of guesstimate the ability to discern pixel sizes with 20/20 vision without any real world testing.


I will say though, at 10 feet, my old 42" TV, it was difficult to really see the difference between 720p content and 1080p content.

I will actually agree that 720p > 1080p is much harder to tell, and i would probably not be able to tell the difference at 10 feet, but 480 to 720p or 1080i is a huge jump.

Try comparing with 480p vs 720p video files instead of heavily compressed cable and see if it changes.

Oh, I know there is something to it. i remember the first time I saw a BR movie playing at Sam's Club on a big TV. My daughter and I were standing about 2 feet from the screen slack jawed. I had a similar experience a few weeks ago looking at a 4K TV from a couple of feet away. I don't get that same experience at home so I know I am not seeing the full glory of 1080p like I could be.

It's all about format and scaling. If the format to the set is lower quality than what the set can do, it makes no difference. If you've got an image feed coming in at 1080p from bluray or another source like a PC video card or gaming system, you might see some benefit if the screen is large enough. Otherwise it makes little difference. Obviously, if you have a larger screen, you'll need a larger room to compensate. Considering how Comcast and DirecTV are handling HD now, I doubt they'll be making changes anytime soon to move up to the 4k stuff...

Yes, this is an old graph if you've done any resolution/tv research in the last 3-4 years. Somewhat useful though. I am about 12~ feet from my 144foot screen. I noticed a nice jump going from a 720p to 1080p projector. I imagine if 4k ever becomes reasonable in a projector i'll bump it to that, but 1080p looks splendid as it is.

My 50" 720p plasma also looks great at about 10 feet still. Would not mind getting something ligther, but it doesn't look like TV's have gotten any lighter, haha.

Found this while trying to evaluate getting a new plasma vs. a 4k TV.

that chart is full of crap.

I wonder... I get the gist of the chart and how it works but wondered how it might change from one person to another based on their eyesight.

Found something on AVS that is related, got my interest, but haven't read it yet:

http://www.avsforum.com/forum/25-hd...e-chart-720p-vs-1080p-vs-4k-vs-8k-beyond.html

Ignore the 2nd post from the person mis-reading the axes. So the chart may not just be off per person but may be off by a factor of 2? Hmm.

My screen is ~100" now and I sit about 8-10 feet away. It's kind of close, but I can't go any farther back and I don't feel like making the screen smaller. Works for me.

I'm at 106 inches and sit 8 to 9 feet back. 1080p looks good.. but move 2 feet closer and screen door effect is really bad.
