Helpful chart for choosing TV size/resolution

[leov36]

i agree with the people mentioning the quality of the tv making a bigger difference than resolution alone.
i have a 720p projector, using a 84inch screen from 10 feet away, when my buddies come over they say, wow, is that 1080p?, i say sure. lol
i KNOW if i were to have a quality 1080p projector set side to side with mine, the 1080 would win hands down, but theres not one there, so im happy with what i got, and you should be too

Something else about the resolution differences is that some things are more noticeable in improvement from 720 to 1080.

I did a mockup of a 1920 wide promotional screencap image of the Joker from The Dark Knight, and I was going to post it on another forum to show off how much better 1080p is than resolutions, but the 720p equivalent resolution version I threw together looked amazing already (although I must admit the low res SD mockup looked terrible). I honestly couldn't tell the difference right away and it took me switching back and forth to notice the faintest difference in the depth of the wrinkles in his forehead as the only cue I could pick up. This was using my 42 inch 1080p screen as a computer monitor from a distance of about 3 feet. I made a sample image specifically made to show off the difference in resolution, and that showed through well, but in actual practice of displaying real film footage, 1080 simply doesn't have that much of an advantage.

It's kind of absurd really. The technical advantage of 1080 over 720 is greater than 720 over 480, but the simple fact is that 720 looks great already. When it becomes commercially viable to have 4K TV sets, will people crucify others for only having 2K or 1080p sets? It's just crazy. Especially for smaller size sets. The added cost to get 1080 on a small set that's going to be watched from relatively far away anyway is absolutely not worth it.

That's because your TV is failing either 3:2 cadence detection or de-interlacing. Most 1080i broadcast sources come from a 1080p source that is converted to 1080i using 3:2 inversion.

Progressive scan just looks great period. Quality of picture is of upmost concern and 1080P is the only way to go if you have Blu-ray.

Not necessarily:

A 1080p SOURCE will provide the better overall picture, not necessarily a 1080p TV as this shootout shows - http://www.hometheatermag.com/lcds/208hdface/

6 of the best 1080p sets vs. a 768p Pioneer plasma.

That 768p plasma is now discontinued, however it was at a nice price and passed both interlacing and 3:2 tests meaning your HD 1080i broadcasts will look better on it too than 720p of the same source.

If you take a 1080p set that fails deinterlacing tests, lets say for instance it discards all the even lines and doubles up the odd lines, and put it beside a 768p set which passes deinterlacing (and 3:2) and display 1080i content on it, chances are you're getting MORE resolution and a display truer to the original source on the 768p set than you are on the 1080p set.

With Blu-ray at 1080p24 of course it's a totally different story as very little processing is required. However given that some sets get down to under 500 lines of motion resolution there will still be times when the 768p plasma is still resolving more resolution.

My parents have a Sony 43 inch, 4:3 aspect projection HDTV from around 5 years ago. It is 1080i. I notice a pretty big difference in clarity when watching HDTV broadcasts on their TV compared to watching HDTV broadcasts on my Sharp 46 inch 1080p LCD. But that probably has more to do with the fact that I got my TV in 2008 while they got theirs in the early 2000's. Or perhaps 1080i just looks like crap. I will admit that when I watch special features, such as the Gotham Tonight features on the TDK Blu-ray, you can't really tell much of a difference between 1080i content and the film content at 1080p. Then again, the TV supposedly upconverts everything to 1080p in the first place. But if you have 1080i or 720p content with a high bitrate and a good codec (VC-1 or AVC), it will look excellent.

@..."Thankfully, being that this is an LCD TV, it wasn't a permanent burn in like with some Plasma displays. But it took a while to get rid of it, and it freaked me out."



^^^^^^ Hows that "special bus".....? And oh ya, thank the lord....

1080i is the same resolution as 1080p, there is no upconverting involved, just deinterlacing.

The absolute pits is switching between playing a game on the PS3 (720p) and playing a game on the Wii (480i...gag). It's almost unbearable to look at.

Ah yes, that is true. I have a 1080i HD DVD player but it is deinterlaced to 1080p with my TV.

Think of it this way. your tv is graph paper.
720p is 1" squares, just to make it easy.
1080p is 1/2" squares double the resolution.

Squares and Viewing Distance:

720p is about 1,000,000 pixels and 1080p ~2,000,000, so 1080p is 2x over 720p. 1/2 +1/2 = 1 in a linear realtionship, as in a number line, which are powers of 1. But we are dealing with an area which is a power of 2. So there would actually be four 1/2" squares fitting inside 1" squares on the graph paper, suggesting 1080p is 4x over 720p, which it is not. Look at the image below of a 4X4 image upscaled to 8X8. You can also see why I would rather convert 480p to 960p with black bars on all 4 sides of the image rather then filling entire screen of a 1080p set.

Square Numbers
The Number Line
Cartesian Coordinates

To get two equal squares to exactly fill the area of a larger square, we have the formula for doubling a square with side of length 'a' for a square of length 'x': x^2 = 2a^2

However, the idea of squares is interesting. If you are at some optimum viewing distance n from your square pixel 16:9 1080p set and cut that distance to n/2, you would need a set with 4k resolution. n/4 would be 8k. The amount of information you can see goes down when you increase distance, and goes up the when you dicrease distance, following the point-source Inverse-Square Law

I know that there is a certain size that HDTVs actually reach 1080p and anything below that size is just 720p. I just want to know how many inches is it onwards that HDTVs are actually 1080p.

Thanks in advance.

Pretty much 32+ all LCD and none are cheap.

Theres been a couple 32" 1080p tv's out along with some 37" 1080p , at that size it's a waist of money, IMO. Anyone who ownes one will tell you differnt (of corse)...

[undertaker76]

it has somthing to do with seating distance as well. however one example on a graph said for me to see 1080p on my 40" sony v series i'd have to sit 5ft away. but at almost double that i CAN see a major diffrence between 720p and 1080p. but the common screen size for 1080p is 46" according 2 many people here .but i had a 720p 50" rear projection tv and was amazed how much more detail i saw on my new 40" 1080p .my experience says big screen big grain its amazing what 10" diffrence make as i tell my wife lol

ps. lord vader your damn right. ilm should be mandatory in all movies.
if its not star wars it's no good
lets see spock try and take on a wookie

The reason why a 1080p screen might be desired on a smaller size wouldn't just be for a sharper image.

but at almost double that i CAN see a major diffrence between 720p and 1080p.

You're glossing over one of the major good points of 1080p when you think the way you are.

It's not just higher resolution image. It's also smaller pixels.

The specific content also has to be considered. Some things show 1080p's strengths more than others. I know I made a mockup image to compare a while back and I couldn't EASILY tell the difference between the 1080p native image and the 720p upscaled image. Both looked good.

But I was still looking at the 720p equivalent image scaled up on a 1080p screen.

Either way, the real thing to consider here is if you're willing to cut corners to get a much cheaper price, or if you're rather pay top dollar for the best-there-is (even if the "betterness" of it isn't constantly apparent). But remember, even though 1080p is technically better, 720 is still HD too.

It is indeed. And it looks terrific on my Panny 42".

But we all don't have the same vision. I sit where I feel is best while viewing. Best chart for me!

[Pelican170]

Seems the that 1080i/p section is about right. I just got a new tv saturday and the manual says for a 50 inch, 7 ft away...

I really don't see the point of the question? You can get 1080p or 720p (768p) on just about any size set you want. There is no "under this size TV, all are 720p" type of size. You can get 1080p in a 22" set, if you want.

By this, you mean you've viewed the exact same content on the same brand TV's, one being 720p and the other being 1080p at the same viewing distance? If you simply mean that you could tell a difference between 720p and 1080p content on the same 1080p set, then this has nothing to do with the chart to which you are referring.

[MoPe]

Smallest 1080p TV I know is 26".

There are also the Samsung TOC series monitors with HDMI, HDCP, and TV-tuner at 22" and 24" that are 1080p. Price is $400+ for the smaller.
