Maybe I'm not searching right, but I can't get find an answer.


I'm about to purchase my first projector set up. I've decided to go CIH but I'm debating the screen size. I have an less than ideal room and a viewing distance of 12.5 feet will allow me to properly place L and R surrounds.

I want to go with a 128" 2.35 screen and a Panasonic AE 8000. My question is, when I zoom a scope movie will I see pixels with this setup at that distance?

Or should I reduce my screen size?

Thanks

Well I don't have the math in front of me, but I am 130" 2.35 screen size, 1st row eye at 10'6", and I don't see pixels, so safe to say you won't sitting farther back at 12'6".
Heck, when I go AT screen in future I'd increase my screen to 140" or so biggrin.gif , bigger IS better after all.

There is also this chart, when I was designing my home theater it was helpful, I overlaid my viewing distance on LH axis and intended screen size bottom axis.
Then you know what zone you fall into.
(yea, being an engineer we do this daily)

More info here Chart Distance x Screen Size - Standards SMPTE and THX

Ok; it's been so long since I used it (2007), I see chart has been updated for 4k, cool.

Those graphs made by Carlton Bale (or anyone else) are pretty wrong (IMHO).

Each person sees different, eye is an optical organ and we need to "compute" the image with brain too.

Have you gone to his website?
He did not "make" them up, rather plotted visual accuity data from objective studies (fact based data, done on statistically controlled sample ) in such a way lay people could grasp its impact.

"S" in AVS is for Science.,,,I see you are a "ISF Calibrator ", implicity I trust you are well versed in fact based data, that is your day job!
You gave subjective data, ....your opinion stating he is wrong.
Can you clarify;
- at what different distances you did your evaluation at
-screen size(s) used
-did you compare 720p to 1080p or?

or simply studies that I can read?

[added info]
I have a 2005 720p 42" Sony "slimline" HDTV in my family room, sit 10 feet or more from it, absolutely no need for me to "upgrade" to 1080p just for upgrade over 720p at that screen size.
However, the newer sets have better PQ than my set, etc, so taking all that into account I might upgrade in 1-2 years.....and go to a 50" also biggrin.gif
