viewing distance.

[Calgaryman24]

Just wondering if 6-7 feet is a good viewing distance on a 32" lcd. 1080i. Is there a magic number with viewing distances, or is it more average preference that is used as a standard reference?

[theknub]

i think standard viewing would prob be 2 or 3 picture heights distant. however, i know of someone in particular who i believe prefers around 1.5. this comes from an old thread and is prob a good rule of thumb

there is a graph on there that can be pretty informative.

SMPTE (Society of Motion Pictures and Television Engineers) recommends a field of view of 30 degrees.

THX, similarly, specifies that the last row should have a angle of at least 26 degrees and the optimum being 36 degrees.

Here's a Web site that has all the explanation and a calculator.

gracias, even better

My sitting distance is 7.7 ft. Should I get a 46" lcd tv or a 40" one? Given the fact that both would be only 1080i maximun capable, Will I be better off with a smaller tv in order not to struggle for 1080p?

How about that info stating that the qualities for chosing a good tv are in order of importance contrast, refresh ratio, and finally resolution, is it true?

[MouseRider]

Viewing distances are determined for perceptive effect and doesn't deal with resolution.

1080p or 1080i isn't going to affect your viewing distance.

Digital displays will all display progressive pictures in the end so the biggest difference between p and i is how good your de-interlacer is if you're using 1080i.

great chart i was wondering why i noticed a great difference between 1080i and 1080p

looking at the chart did you notice 1440p

HD-DVD can't do 1080p with uncompressed PCM like BLU can, due to space limitations now

R.I.P. HD-DVD

this strengthens the arguement for BLU-RAY

The optimum viewing distance is about 2-3 picture heights. Beyond that, it is mush IE the projector can be out of focus a bit and you can't tell much difference. The same rule applies at home.

At 46", the width of the TV is 40.11". Watching 1.78/1.85 movies, the picture height will be 22.54". Watchin 2.40 movies, the picture height is 16.77". So minimum distance equals 2 PH of 2.40 movies is 33.54"/2 feet 8 and maximum distance is 3 PH which is 50.31"/4 feet 2.

ROT is 2x tv width

3. Viewing Angle

a) Horizontal

The angle subtended by the left and right edges of the Cinemascope image and the farthest seat in the auditorium is recommended to be 36 degrees.

That's 3.6 PH for a Scope movie. Means that the farthest you should watch Scope movies on a 16:9 display is 1.33x the diagonal of the 16:9 screen to get that theater last row viewing angle. Remember that's the farthest.

THX and SMPTE recommendations aside, are these recommendations for SD or HD? One could get closer to an HD screen without seeing pixels, for example. (Conversely, with SD, you'd want to be at least xx feet away, to avoid seeing pixels.)

got 52" lcd bravia xrb2 i see at around 8 feet
