Is it true that you won't get the full effect of 1080p unless you have a 40+ inch tv?

[kramer733]

As the topic states. I've been reading stuff like this for quite awhile now and will be buying my first hdtv tomorrow. Would like to know.

Depends on seating distance.

[Aphanasis]

I've wasted far too much of my life looking at that graph... Having said that, it was the main influence in my decision to get a bigger TV for movies.

It does make me wonder how accurate it is though. I'm sure there's some mathematical way to work it out. I'd be interested to know how it was calculated.

Nope.

I have a meager 32" TV. I must sit ten feet away from it. But I can still notice a definite improvement in sharpness and detail when watching Blu-Rays.

Now, when I'm at my desk 20+ feet away, then I can't tell the difference.

I do want a bigger TV later in life, but I gotta save up for it first.

Are you saying you notice a difference between DVD and Bluray? Or 1080p over 720p? If its the latter how did you test it?

From DVD to Blu-Ray. After a while, I can't help but to notice that most DVDs look kinda shoddy (espcially those older ones that aren't even anamorphic widescreen).

I don't think I have any 720p Blu-Rays. I do have a few 1080i Blu-Rays, which are notably more pixilated.

I do notice that 720p PS3 games are a heck of a lot more pixilated than 1080p games; full HD games are smoother and better looking.

Aside from being at a lower resolution, DVD are encoded with an older compression tech and at a way lower bitrate than BD. And older non-anamorphic discs.... well they suck. I have no doubt you can tell the difference between DVD and BD.

I've never even heard of a 720p Bluray disc. 1080i discs are either a studio being really lazy, or a non film 50/60 hz source.

You can probably force your player to output at 720p. If so, put in a 1080p disc one that looks really great, and have a friend randomly switch the player from 1080p to 720p without you knowing. And see if you can tell the difference.

[DRC72]

IMHO... I think images look a little more jagged on 720p displays compared to a 1080p displays, but I only notice it on 40' inches and up.

[Anthony P]

I don't know what "full effect" means, but even on something smaller then 40" the difference is visible.

[Steedeel]

It is only Apple fans (in my opinion) trying to convince their selves that 720p 4mbps is great quality! People will always try to tell other people what they can and cannot see. Trust your own eyes. I can tell the difference quite easily. I would advice you to go with the full Hd 1080p.

Six feet or twelve feet is matter-less. you will still see some difference.

... or those of us with 720p plasma screens

I can somehow tell the difference between BD quality and say hulu+ or Netflix HD streams, even though I'm watching on a 720p (actually 768 line) screen. Resolution isnt everything.

As things are now, buy a 1080p TV they're only marginally more than 720p. But if you already have a 720p TV, don't feel as though you need to rush out and buy a 1080p set.

I wouldn't touch anything by Apple with a 10 ft pole.

Here's one of them:

1080i discs are either a studio being really lazy, or a non film 50/60 hz source.

Film can also be shot at 25 fps so would need 1080/50i (or 720p50) to be properly encoded on Blu-ray.

Here's one calc (for max viewing distance for fully resolvable resolution):

max viewing distance for 720p tv [ie. 1280x720 fully resolved] = screen width * 2.7

max viewing dist for 1080p tv [ie. 1920x1080 fully resolved] = max viewing dist for 720p TV / 1.5

I sit 3 feet away from a pioneer 151fd thats trained to kill me with its 1080p panel

The only film shot at 25p is made for television in 50Hz countries. And (I'm nearly 100% certain on this) any 50/25fps sourced material is converted to 1080i60 for release in North America.

Also some European feature films are shot at 25 fps (eg. to make it easier for when they are broadcast - according to one cinematographer).

And (I'm nearly 100% certain on this) any 50/25fps sourced material is converted to 1080i60 for release in North America.

Or converted (slowed down) from 25 fps to 24 fps (23.976 fps), eg:

Planet Earth - the Complete Series 24 fps.
https://www.blu-ray.com/movies/Plane...h-Blu-ray/384/

Pride and Prejudice 24 fps.
https://www.blu-ray.com/movies/Pride...-Blu-ray/1201/

But things like that also happen with a lot of (incorrect) European releases too.

I'm just now reading this post days later, but I want to add my strong views on this.
I'm a long time photographer and former photo technician.
Short firm answer is "Yes!". It is true that you won't get the full effect of 1080p unless you have a 40+ inch TV.

I consider 40" to be the minimal size screen for anyone who wants to have all that's there for the seeing. Be sure that whatever set you buy, to optimize it.
Ground rules: Minimum sharpness setting-- just to where you can it start to work, view in dim light, use about 60% backlight and
the Cinema setting, also called Movie. This is the correct standard mode.
Then buy a Disney WOW disc and follow the basic instructions. You will find you have never actually seen HD till you done these things.
720 is not true HD. No matter what is said about viewing distance, it can't show what's on a BluRay disc. It has only half the detail.
Forget the chart.
The optimum viewing distance is just far enough away from the screen for the pixels to 'disappear'. The HD experience is best when the screen fills your forward vision. This is what makes 'home theater'. If you can afford it go, bigger than 40'.

My room is 8 X 11, I sit about six feet away from my Samsung and I wish I had a bigger screen. But never a day goes by I am not some level of amazed at what I see. I seldom go to the movies because it's such a big step down.
I hope you got something nice.

You haven't included viewing distance in that statement.

Viewing a TV less than 40" from closer than the 40" TV could allow you to resolve more than viewing the 40" TV from further away.

It's the screen size and viewing distance that you need to take into account (and pixel resolution of the screen and amount of resolvable detail in the content).

[Atreyu]

We had a 37 inch in the living room before getting our 65 inch and I noticed full 1080p. Just as much as I do now. Granted we sat a lot closer to the se though.

[Steedeel]

Botton line, always go for full HD regardless of distance.
