How can anyone with a 50" screen sit 5.6' from it? That's just lunacy. My eyes would jump out of my sockets and yell at me if I did that.
Nemo, a lot of people seem to say this kind of thing. I believe, if what you say is true, that you cannot ever enjoy a movie theater. Even from the back row.
I just saw two movies (and it's been a year or so since I last went). Both movies were in different digital DLP projector theaters.
I saw UP from 1/3 from the front. I saw Terminator from about 3/4.
3/4 back from Terminator was nearly identical in viewing angle to my front row, which is 42 degree viewing angle, or only 4.7 ft from a 50" TV.
UP from 1/3 back was significantly more immersive than my front row. I will guess 4ft from a 50" TV to be similiar. Give or take a couple of inches.
Do your eyes jump out of your sockets and yell at you in the theater?
Now, I am somewhat confused as to what exactly the THX rec of 36 degrees applies to. For many, for a while now, I think people believe it to be the middle row of a theater. However, I've been told by videophiles that 36 degrees is the THX recommendation for the BACK row of a theater.
Therefore, 5.6' from a 50" TV is the back row of a THX spec'd theater.
Just want to put this in perspective for those who think this way.
EDIT: I was going to attach a diagram here that I've posted before, but it appears to have been deleted.
