720p or 1080p what size screen starts to make a difference

[mike4scuba]

At what size screen do you actually start noticing a difference in picture quality from a bluray player

is it 19, 22, 26 or larger screens

if its say a 26 screen you notice a difference, then buying a 22 screen would be better in 720p i guess in that option a good dvd upscaler would be as efficient as displaying an image as a bluray player

Discussing screen size alone is totally meaningless. What is your seating distance? A 40 foot wide screen is small if viewed from the opposite end of a football field. I have a 17" diagonal screen on my laptop. It's 1920 x 1200 resolution and at times I can detect pixel structure in the image. All I have to do is lean forward a couple of inches in my chair and that resolution is not enough.

High definition video was developed first in Japan. NHK conducted substantial human factors research and determined that a person with 20/20 vision would need a 30 degree viewing angle for a 1920 x 1080 image to look smooth. That's a viewing distance of roughly three times the screen height, or 1.5 times the diagonal. Anything larger would allow the average viewer to detect pixel structure. Smaller viewing angles would all look smooth. There may be a slight variation in visual acuity from one person to the next, but not much for the majority of people.

but i would need a lager screen tv if it was 1080p over a 720p over the same viewing distance

I've always read that 1080p becomes most advantageous on screens 50" or larger (measured diagonally), unless you sit really close to your display. Then 1080p would be advantageous on smaller displays as well. This is just kind of a rough guideline though.

Honestly, if you would of asked me last year at this time, I would of said for anything under 40", just grab a 720 as you probably won't notice the difference. Now, seeing the way these sets are priced now, I say go with the 1080 regardless, because I don't really think the 720 will be around next year in anything bigger than a 22 inch. Not that it makes a difference with the picture, but I think less decisions for the consumer will make it easier for them to make the jump to HD if they haven't done so already. Just my $.02 of course.

Disagree... however it is sentiments like this that keep the price of a 720p at the ridiculous level it is compared to 1080... there are much more important factors in a TV than the resolution...

If you are a normal person who sits 8-10 feet away from your tv, even a 50" will look virtually the same... the unfortunate part is that there are so many variables, and without placing assumptions for those variables, you really have an infinite amount of correct solutions...

Any TV 42" or under I wouldn't worry too much about 1080p. Anything bigger the 42" then I would buy 1080p. You could check out this article:

720p vs. 1080p HDTVs: 2009 update | Fully Equipped - CNET Reviews


Quote from Cnet: "Whether you're dealing with 1080p/24 or standard 1080p/60, doesn't alter our overall views about 1080p TVs. We still believe that when you're dealing with TVs 50 inches and smaller, the added resolution has only a very minor impact on picture quality. In our tests, we put 720p (or 768p) sets next to 1080p sets, then feed them both the same source material, whether it's 1080i or 1080p, from the highest-quality Blu-ray player. We typically watch both sets for a while, with eyes darting back and forth between the two, looking for differences in the most-detailed sections, such as hair, textures of fabric, and grassy plains. Bottom line: It's almost always very difficult to see any difference--especially from farther than 8 feet away on a 50-inch TV."

I disagree with cNet - it does matter.
I find the difference VERY noticeable even on a 22" monitor.

However, panel resolution is really so far down the list of considerations that it baffles me why it's the #1 talking point. As already pointed out in this thread, ANSI contrast ratio, calibration options, video processing, colour accuracy, etc., are all far more important.

You are 100% correct in regards to "ANSI contrast ratio, calibration options, video processing, colour accuracy, etc., are all far more important"

My brother has a samsung 1080p 40" LCD and I have a Panasonic 720p 50" Plasma and the same bluray movies , both played on a ps3 with same settings look noticeable better on my 720p set than his 1080p

This may be a stupid question, but what if a person has difficulty disinguishing some colours from others? I, for example, have a very difficult time seperating black from deep blues like navy. The lighting condition has to be spot on for me to see the difference. Same goes for aquas and turquiose. Does this play a factor?

Size and distance do matter but I'd take a 768p display that has great motion res, color acc, ANSI, deep blacks, video pro & many other things that give the kind of picture I want over a 1080p display that doesn't. As luck should have it, I have a few displays that make the cut. I sit with-in range to enjoy all of there greatness!
