My main point here is really that the interpolation issue was irrelevant, at least to the eye anyway.

Even your 768p display must interpolate lines worth of pixels in order to fill the screen. If it did not, there would be more than 61k black pixels on your screen (>6%). I believe "the eye" would notice.

I believe I wrote you should look a screen greater than 50" (50+"). However, "A 50-inch 720p display, at a distance of 9 feet or so, can look similar to a 1080p displaydepending on factors such as the viewer's visual acuity (ability to resolve pixels) and the nature of the content. . . .Moving closer to the screen reveals the details 1080p brings out because the image fills more of your field of vision." http://www.electronichouse.com/artic...out_1080p/C204 . My viewing distance is just under 8'.

Here are a couple more data points.

It doesn't show a difference in angles for 1080p or 768, just the last line shows the recommended distnce for 1080x1920.

According to Sonystyle.com.... the same size LCDs have this viewing angle
1080p - 178° wide viewing angle LCD display panel
768p- Viewing Angle --- Right/Left: 178°, Up/Down: 178°

A screen with smaller, denser packed pixels (1080) with not fade, lose contrast, experience color fade, etc. as acutely as the same size screen with larger pixels. Try it out with your CC bud, you will see a difference.

BTW who died and made Sony king? They appear to be your favorite source. They are but one company of many out to sell a product. And based on some recent issues with some of their sets, not necessarily one of the best.

I might be on the borderline if I should upgrade to a 1080P. I sit 9ft away with a 42" Samsung Plasma. The picture is awesome but I want a bigger screen. Thinking about the 50" 1080P plasma or the 52" Sharp/Samsung LCD. Do you guys think I will see the better picture? I do have a blu-ray player...

You really are borderline. The best advise I can offer is to view both sets and just buy the one that looks best to you. If you can stand back 9' and don't notice the pixel structure on a 768p set then it may be the right set for you. It should certainly be less expensive and the difference in resolution may just be a toss up. A down-rez'd 1080p will still look pretty awesome. Remember, display resolution is 4th on the list of items that contribute to picture quality.

Where did I say that the 768 set did not interpolate?
What I was saying is since all the tests said that there was no difference with a 1080 signal on the 1080p set and on the 768 one, the interpolation of the 768 set proved to be irrelevant.
Please read what I was saying, and I agree with the articles you provided, I said all along my point was for the distance of around 10 feet for a 50 inch set.
A far as, do 50 inch sets display a poorer signal than a 40? That is another topic for another thread.
I'm talking 1080p 40 inch vs 1080p 50 inch as well as 768 40 inch vs 768 50 inch.

Thanks for your help. Another reason why I might just get the 1080P is justifying spending 3,000 grand for a T.V.

if you're spending 3,000 grand ($3mil) on a tv, i would expect much better than 1080p!

Not "on an angle" but rather your angle of viewing. This is not so much the rocket science as you are attempting to make it. In other words, at 10' viewing distance on a 50" display, you will only achieve a 20.9 viewing angle. No good for a home theater experience, and at that distance hard to enjoy any benefit from 1080p. But if you bump up the size of your display to 60" and view from 10', then your angle of viewing increases to nearly 25 degrees. Not perfect but enough to eliminate that postage stamp viewing experience and enough to enjoy the added resolution of 1080p. So if you are truly interested in achieving a home theater experience use THX & SEMPTE "viewing angle" recommendations or something close to it, and you will also be able to see the added resolution of 1080p.

Yea I see your point,
If you want to sit to close enough to a set see the full 1080p your angle of viewing increases with a bigger set like 60 inches.

Doesn't really have too much to do with my point about the max resolution of the eye at 10 feet for 720p, but I'm glad you made it clear anyway.

Thanx

The human eye can resolve far more than 720p from 10'. Your "10 feet for 720p" comment is valid only for people with average vision watching a 50" or smaller screen. If someone prefers the more "theater like" experience offered by a 60" or larger screen, then they can resolve more than 720p from that distance.

I did reread and it still says the same thing to me......."My main point here is really that the interpolation issue was irrelevant, at least to the eye anyway." We just have a failure to communicate. No biggie

Hi Folks,
I am a newbie poster but a longtime reader of this forum
about ready to buy a 720p LCD, (JVC 42E488) .

720p may work out fine for me ( 42", 8ft typical viewing
distance, mostly TV - will spend half my budget now to
get my first HDTV, then in a few years upgrade like many
of you guys have been doing for quite a while now ...
the 720p set will then become my "perfect" bedroom set,
while my new set should be 3x better , 1/2 the cost, and
contain more mature technology (hopefully).

Unfortunately, none of the stores in my area have a PC
connection demo and I don't have a laptop so ...

My questions are : What is the expected performance
of 720p sets when hooked up to a PC. How "readable"
will my email be from 4 ft - 6ft ?(keyboard on coffee table)
Will I be able to search the Web and read the static
text clearly from 4 to 6ft ? What is the distance limit for
this situation with 720p and 1080p ?

( I suspect 1080p will be better, but will 720p be OK ?
Please note that I am not a gamer since then the answer
would be very obvious ! )

Setting aside issues like overscan, are there any guidelines
or suggestions for viewing distance vs screen size for 720p
and 1080p when using a PC hook-up for reading text ?

THANKS !!

My points are for people with 20/20 vision, the charts have been provided. Yes 50 inch sets were used for examples. But the point is what mainstream considers normal viewing distances for big screen sets. Go out and ask 2000 people that have a 60 inch set how far they sit from their set.
For a 60 inch set the distance to pull in 1080p is 7.8 feet. The mainstream world does not sit that close for a 50 inch set, and I don't on my 40.
So please come back and tell me you have greater than 20/20 vision or that you pull a chair under 8 feet for your 60 inch set. This is what I wanted from the get go.

Would that not be a great advertising slogan?

"For the same screen size, (article addressed a 50" set) the benefits of 1080p vs. 720p start to become apparent when closer than 9.8 feet and become full apparent at 6.5 feet. " http://www.carltonbale.com/2006/11/1080p-does-matter/ So it seems there is a 'gray area' where one can detect higher resolution but you do not get the 'full' impact unless you sit nearer to the set.

BTW, I sit less than 8' from my set. I bet others do too. We don't all have large family rooms.

Set up my 64" CRT RPTV (Philips 64PH9905) ~7 years ago, before plugging it in, for what seemed like 'immersive' widescreen viewing. Wasn't until a year or so later I calculated my ~8' viewing distance was about right (8.4') for 1080i/p and screen size. While many may not sit close enough to benefit from HD's key purpose, wider more-immersive picture angles (~33 degrees), they can be educated to the benefits of more lines/rows of resolution. A long-time HD advocate outlined HD benefits and misconceptions. All my viewing, and that of many other CRT-display owners (still quite numerous), is at 1080/60i (30i), not 1080p. My cable STB converts 720p and 480i to 1080i. -- John

Closer than 9.8, so it not 9.8 feet... it's his write up.. he also says fully apparent 6.5 which contradicts the TXH distance of 5.6 feet.

Although he never says from his perception where the difference may start to begin under 9.8 feet it does not contradict my statement that for a 50inch at 10 feet the max resolution of the eye is 720p. You could try to pull 1000 rabbits out of 1000 hats and that has been my point from the get go.
As far as you telling me that you sit closer, you proved my point. The full HD thing gives people the perception that they are really not getting what HD should be hd with 720.
In reality, and I say " FOR ALL PRACTICAL PURPOSES" in average conditions and where the majority of people sit when watching tv, they will not benefit from watching a 1080p set, and the article you provided verifies that.

"So, most consumers will not be able to see the full benefit of their 1080p TV."

Ahhhhhhhh but MOST consumers WILL see benefit over 720p (on a 50" set) when they sit 9.8 feet or closer. He even provides you a nice chart. And you KNOW for a fact that MOST sit more than ten ft. from their set? Where did you discover this?

Please do your homework. THX for a 50" display with a 26 degree viewing angle, is 7.9 feet and a fully resolved 1920x1080 is 6.5 feet, right in line with the article I quoted. http://www.myhometheater.homestead.c...alculator.html

What this tells me is that "most" consumers need to be educated on HDTV and home theater in general. A person may learn that they need to rearrange the furniture to achieve proper viewing distances & field of viewing angle in order to get the benefits of their $4000 TV. Or, they could discover that their room and desired/preferred seating distance requires a 60+" display to enjoy HD and home theater. If you follow those guidlines or close to them, you will want 1080p.

For the last time Nmlobo , learn to read what people are saying.

Nmlobo stated....
You said this
"Ahhhhhhhh but MOST consumers WILL see benefit over 720p (on a 50" set) when they sit 9.8 feet or closer. "


He did not say at 9.8 feet,.... he said closer than 9.8 feet... Don't attribute words to people that they didn't say.
You will not resolve 1080p on a 50 inch set at 9.8 feet... or any 1080p benefits at exactly 9.8 feet... 9.8 feet on a 50 is 720p viewing,,...again he said closer.... you will see some benefits.
9.8 feet is about the max resolution of the eye for 720p on a 50 inch set...
What he appears to be saying is you have to get closer of this 720p distance on a 50 inch set. to begin to see some benefit of 1080p.. not full HD until you get to 6.5.
9.8 feet for a 50 inch is for max 720p viewing not 1080... this is why he is saying you have pull closer... here they round it off 768p viewing to 10 feet.

"In a 50-inch plasma display with an array of 1366x768 pixels, the pitch of individual pixels is typically less than 1 mm (about 0.9 mm), which equals 0.039 inches. Do the math, and you'll see that standing 10 feet from a 50-inch plasma means you can barely perceive the HD pixel structure, and that's only if you have 20-20 vision."
http://proav.pubdyn.com/2005_January...rallaxview.htm

So move closer from this max 9.8 feet for 768 distance on a 50 inch set to start and you will not see 1080p until you get to 6.5

This is the second time you misinterpret what I say and now you're doing it with articles. He is saying you have to get closer to this 720p distance to start...
But you are not fully resolving 1080p on a 50 inch until you get to 6.5 feet.
The 7.9 foot angle is for 50 inch sets regardless of what the resolution is.
It is only the last line of that calculator that refers to 1080p viewing.

You did this the other day as well when you said that I said 768p sets don't interpolate.

Please take your time in reading something before you respond.

Your comment or question..

"And you KNOW for a fact that MOST sit more than ten ft. from their set? Where did you discover this?"

My friend, use your common sense

1080p advocates or not... I don't think you will find much support in people saying that the majority of the people who own 50 inch sets sit closer than 10 feet from their sets. I don't think you find many saying they sit under 12 feet.
It was he that said this
"So, most consumers will not be able to see the full benefit of their 1080p TV."
http://www.carltonbale.com/2006/11/1080p-does-matter/

You're trying to twist his words into saying most people will see that difference when he said the opposite.

"Nmlobo stated....
You said this
"Ahhhhhhhh but MOST consumers WILL see benefit over 720p (on a 50" set) when they sit 9.8 feet or closer. ""

If that is not a spin on someones words nothing ever was in this world.


You can't see from that statement he made he is talking the majority of people ...won't see a difference?
I'm not saying this to be cocky but you have a very strange way of interpreting peoples statements and what they are trying to say or twisting it.

That is not the point of where people are going to see benefits... he saying that the majority of people will not see benefits because they don't sit close enough to the set.

This is like saying... the majority of people that sit at 6.5 feet from a 50 inch set will see full 1080p. Of course they will... but do most people, the article is leading to no they don't.
I never said that 1080p will not have benefits at the right... or close distance.

What are you trying to pull a lawyers tactic?
All the people will see benefits if they sit close enough. Not is not the point. The point is WHERE DOES THE MAJORITY SIT.

The comments about most people is not if they sit that close they will see a difference.... but WHERE MOST PEOPLE SIT, and where most people sit they will not see that difference. This is what he is saying.

Re read my statement as well... I said from 10 feet with a 50 inch set.... people will not see a difference.

Not going to waste much more time with someone who can't interpret peoples statements.

Sole_Survivor, I am not trying to argue with you - only explain. I believe you were nit picking but okay, if you sit at 9.799999 feet (not 9.8') you will START to see the benefit of 1080p over 720/768p.

Your statement "So move closer from this max 9.8 feet for 768 distance on a 50 inch set to start and you will not see 1080p until you get to 6.5" is only partially correct and misleading. Had you wrote that you would not see FULL 1080p resolution until 6.5 feet would be correct. You would see an improvement over 720/768p at 9.799999 feet that progressively increased in resolution as you moved closer to 6.5 feet. At 6.5 feet you would realize the FULL effect. Do you think 1080p resolution just magically snaps into view when you reach 6.5 feet? Reread the article one more time and you will see that the author wrote the benefits of 1080p vs. 720p start to become apparent when closer than 9.8 feet and become full apparent at 6.5 feet." http://www.carltonbale.com/2006/11/1080p-does-matter/

The author's statement had a qualifier which was In my opinion, 6.5 feet is closer than most people will sit to their 50" plasma TV (even through the THX recommended viewing distance for a 50" screen is 5.6 ft). You quoted the last sentence onlySo, most consumers will not be able to see the full benefit of their 1080p TV. Which, when quoted alone is misleading. Together, these sentences mean that in his opinion most people sit further than 6.5 feet from their 50 set and when they do, those viewers will not see the FULL benefit of their 1080p TV.

You are correct that his focus was viewing distance. And he wrote So pick your display size, then measure your seating distance, and then use the charts above to figure out if you would benefit from the larger screen size. IMHO many (notice, I don't use the word majority - unlike you, I don't know how the majority of viewers watch TV) many people use charts like the one in the article and try to arrange their seating to get the most impact.

Several folks on this forum have attempted to explain things to you. I see you are a newbe but when the "majority" of folks seem to get it, one would expect the light to come on or that you would at least pay attention. You've been a member of this forum less than two months. You've made 66 posts and all of them within this one thread. There is more to HDTV than 1080 vs 720. Some like it, some don't. Resolution is #4 on the picture quality list

1) contrast ratio
2) color saturation
3) color accuracy
4) resolution

Its not that big a deal. Get over it.

I'll modify your closing.......Not going to waste much more time with someone who can't or refuses to understand.

The distance viewing/screen size numbers are rather sloppy and vary a lot by a zillion factors. Meanwhile, screens are sold by diagonal size and it's a pain to do the math. So I usually prefer to just say you might (or not) start to see some benefits to going beyond 720p if you sit closer than about 2 screen diagonals away. That is about 4 screen heights It works out to give similar results and is probably close enough for government work.

Closer than 3 screen heights would really be the place where we would start discussing even greater than 1080p and the economics don't justify that yet for most of us.

edit: note we are trying to find the place where we can't see any of the pixel/raster structure, not where we can. We don't want to see any of it because it is obviously artificial and distracting.

Why don't we power our electric cars from greener, cheaper

How many posts I made or how long I been here is irrelevant to what the truth it.
Yes I posted on just this thread, perhaps I came here to prove something, and when we agreed to disagree about a month back, I have.
I think it is obvious to everyone that it is you who continually misinterprets articles and posts.


You stated
"You would see an improvement over 720/768p at 9.799999 feet that progressively increased in resolution as you moved closer to 6.5 feet. At 6.5 feet you would realize the FULL effect. Do you think 1080p resolution just magically snaps into view when you reach 6.5 feet."

But it is not clear what benefits or what you will see at say 8 feet with a 50 inch set. You are failing to realize that.
For all practical purposes it is pretty easy to see what he is saying.
9.8 is the max resolution of the eyes for 720p for a 50 inch, obviously if you have a 1080p set the closer you get after this point you're going to see more detail, it doesn't take a rocket scientist to understand that. It's how much more will one see when closer than 9.8 & further than 6.5 (not even going with the THX 5.6) is undetermined. It is common sense the resolution starts to increase over 720p when you start to move closer than 9.8 feet for a 50 inch set. Will a distance of 9 feet from a 50 inch allow your eyes to resolve 780p? We don't know
20/20 vision will not resolve a pixel resolution of 1080x1920p according to THX at more than 5.6 feet, and according to the authors article 6.5.

I spoke to a lot of 1080p proponents throughout this thread as much as they may agree to disagree with a lot of what I said, I really doubt that you will find many people that will disagree with me when I say that the majority of the people in this world that watch 50 inch sets in their houses do not sit closer than 10 feet.
That has been my point from the get go.
This why the article stated most will not benefit from 1080p. He is talking the majority of the mainstream world, normal conditions, and as I have said, for all practical purposes, there is no difference.

I'm going to talk to you in lay-mans terms.
Do you have any idea how insane pulling a love seat recliner and long couch say 6 feet to any living room TV will look (never mind a 50 inch)?

The people who visit will think what the hell is wrong with them people, it looks crazy. Even with smaller living room space, it does not look normal.

Your insults or your attempts to take the attention off of your misinterpretations will not work and are obvious to the readers here.

That may be true for the average person. But AVS members are not average, so you can't make those sort of assumptions when you post or recommend displays on this forum. I would not be caught dead with a 50" display from a viewing distance of 10 feet, and I am sure the same can be said for many other members as well.

As far as THX, their recommendations have nothing to do with high-definition. They are focused on the theater experience. Many theaters place their screens and seating based on their recommendations. Obviously, if you buy a 50" for viewing from 10', you don't care much about the "theater experience," because you don't come close to duplicating the viewing angle found at the rear seating area of most good theaters.

Exactly, and I've been trying to get this point across on several posts. If you are an A/V enthusiast, AVS Forum Member or just someone wanting to achieve a home theater experience NO ONE would recommend buying a 50" display for a preferred seating distance at 10+'. If you ARE one of those uninformed individuals viewing a 50" HDTV from over 10', then please by all means educate yourself and realize you need a larger display for your preferred seating distance, otherwise you are missing out on most of the benefits this new video tech has to offer in home theater.

You know if you back up far enough it won't matter one hell of beans if you've got that 1971 Console Color TV or the latest 2007 1080p flat screen TV. But if you don't want that postage stamp viewing experience, and want a more home theater viewing experience for all those Netflix & Blockbuster DVD's or HD-DVD/BluRay disks you're renting, not to mention the HD broadcasted movies, etc. then try to follow THX & SEMPTE guidelines as much as possible. If you do, then you'll want a LARGE display w/1080p.

BTDTV stated.
"As far as THX, their recommendations have nothing to do with high-definition."

Thanks I must have read it wrong....

"Maximum Viewing Distance for HDTV(Fully resolved 1080i; 1920 x 1080)"

"Viewing Distances based on Visual Acuity: These distances are calculated based on the resolving power of the human eye (reference), or visual acuity. The human eye with 20/20 vision can detect or resolve details as small as 1/60th of a degree of arc. These distances represent the point beyond which some of the detail in the picture is no longer able to be resolved and "blends" with adjacent detail."

http://www.myhometheater.homestead.c...alculator.html

50 inch TV

6.5 Feet Maximum Viewing Distance for HDTV(Fully resolved 1080i; 1920 x 1080)

BTDTV stated.
"But AVS members are not average, so you can't make those sort of assumptions when you post or recommend displays on this forum."

What I been saying all along
I said
"This why the article stated most will not benefit from 1080p. He is talking the majority of the mainstream world, normal conditions, and as I have said, for all practical purposes, there is no difference."

This was the comeback I was waiting for and what I wanted the neutral readers to see, this is why I said that, I knew a few would actually come out and say they sit close to their set.
Just one small request please, show me a picture of your living room with the 3 seat couch ... love seat 6 feet from the set with a coffee table between them.
Then again don't, I'll laugh so hard the ambulance will have to come and give me oxygen!

Also keep in mind that if the front of your couch is 6.5 feet from the screen, your viewing distance is over 7 feet once you sit and drop your back against the couch.
For eye distance of 6.5 feet (where your body rests back) you would have to place the seats somewhere right under 6 feet or around that.

This is how far they will go...
The other one is almost trying to illustrate that watching a 50 inch monitor at 10 feet is like looking at a postage stamp.

Far enough... 10 feet was the issue not watching the TV from the next street over.
My points were made!

That's a feature they recently added to the bottom of the table. It doesn't have anything to do with THX or SMPTE recommendations for theaters, it's for informational purposes.

You are preaching to the wrong crowd. Your comments are more appropriate for forums like Good Housekeeping where people are concerned more by form (aesthetics) than function. Here at AVS, a high percentage of members want to re-create the theater experience, and you can't do that with a 50" from 10 feet. Some can't put a big screen in their living room, so what do they do? They dedicate another room -- or build one -- as their HT room.
