Helpful chart for choosing TV size/resolution

[laddie]

Excellent Chart.

Excuse my ignorance I am a rookie at this. I have seen the posting of America video and did check out a Gizillion postings before jumping on this one.

Qn ....If all bluray disks are, or will be filmed in 1080p, is their a huge risk in buying the lower resolution TV screen 720p??

And is 1080i equivalent to 720p ??

[U4K61]

1080i can be similar to 720p depending on setup and source. Correctly deinterlacing & scaling 1080i from 24fps film to 720p to be displayed on a 720p set makes 1080i similar to a native 720p signal only because most sets are not native 720p but rather 768p. But you can't go from 720p to 1080i without a loss of PQ over a native 1080i source because 720p is not bi-directional to 1080p/i, meaning it does not map 1:1, so they are not equivalent. Or in simpler terms, 720p does not have the same number of data points as 1080p or 1080i correctly deinterlaced to 1080p.

If you have a 720p TV, I would first try and see if it hand-shakes with 1080p, if not, 2nd best 720p/1080i, where then it becomes a question which does a better job, the TV or the STB. There were issues with early Blu-ray players doing poor down conversion from 1080p, so in these cases, 1080i provided the better PQ.

A trap is 480 DVD upscaled to 1080p and then downconverted to 720p. The PQ will be lower then if we just set it as native 480p.

A 1080p set should be fed 1080p, but if it's getting 1080i sourced from 24fps film, it can be de-interlaced correctly back to 1080p. As just mentioned, converting 1080i/p to 720p and then scalling it back up to 1080p is not the same as a native 1080p signal.

A formal look at equivalent

this is the same chart we use at circuit city pretty much

Last year i got a SAMSUNG 42" Plasma HDTV w/ ATSC Tuner HP-T4254,
I have a ps3 and about 50 blu-movies. They all look amazing on my TV, I know that it is not 1080p. but how much better is 1080p over 720p?
btw i do plan on getting a 1080p set in a few months.

[ixlegitballinxl]

imo, 1080p is a must have if your into blu rays... better PQ due to more resolution... crisper picture, plus 1080p gives you a lot more room to work with seating wise > can be further away from tv if needed

[BTBuck1]

i just prefer it period, be it a computer monitor, cable HD or BD i can see the increased resolution.

720p has the screen door effect to me now when i see it.

[tbizzle]

1080p is the only way to go. Really, once you get a nice 1080p set in your home, nothing else compares

[FendersRule]

Most PS3 games are 720p.

However, 1080p is still the screen to get.

[Midnightsailor]

I love 1080p.

[mophious]

If u play Call of Duty 4 or 5, You can feel difference with 720p and 1080p.

[forumid]

I was going to post this same question but hadn't had a chance to search the forums to see if it was asked and answered yet. Now that I see it posted, I will jump in (not to thread-jack but to ask more of the same).

BTBucks "screen door effect" comment is the type of feedback I'd like to see. I too have a 720p screen and just by looking at the numbers, I know a 1080p screen will look crisper and sharper. However, what I want to know is what is the difference in the real world? How much sharper is it really? Are people bleeding from the eyes it is so much sharper than a 720p picture?

FendersRule comment also made me think. I don't have a PS3 but from what I understand, HD broadcast channels do not broadcast at 1080p either. All are either 720p or 1080i (which my screen can also handle). So is the purpose of getting a 1080p screen is to scale up the 720p to 1080p and de-interlace the 1080i or just for the benefit of blu-rays and and up-converted DVD's?

I look at the 720p and 1080p screens playing next to each other at the local best buy or circuit city and they just don't look like a difference worth shelling out another 700 to 1500 or so from my pocket.

By the way, I am not trying to dampen anyone's spirit on 1080p. It is definitely better, I know that. I just want to know what the specific differences are that people notice from one to the other that I don't know about or understand. Thanks.

Being Your TV is 720p it will accept a 1080i signal,but you are not getting 1080i resolution

so 5 is in 1080p, thats a bonus over the 360 version.

[UFAlien]

But Call of Duty 4 only runs at 640p... it'll upscale, but I can't imagine the difference is that impressive.

[Bourne1]

I'm looking at the back of my COD4 box and it says "Supported HD video output: 720p, 1080i, 1080p". When I first started playing this game, my PS3 defaulted to 720p. For about a week I was playing at 720p until I finally decided to only set my PS3 video at 1080p. The difference was huge for me, it was more crisp, especially looking at the opponents at further distances; I was getting more headshots from across the maps.

The main difference between 720p and 1080p will only be noticeable if the TV is a 46" display or higher. Once you breach the 46" scren size barrier, that's when lower resolutions begin to show their true natures. So, for any TV under 46" in size, there is no need to worry about the difference between resolutions.

* At normal viewing distances of 8-10 feet.

It is very noticable even on laptop displays given the proper viewing distance.
Same goes for desktop computer monitors at their ideal viewing distance.

One does not need a 46"+ display if one is not 10 feet away from it.

First off, to get 1080p does not cost 700-1500 dollars more nowadays. Maybe $200-300. The deciding reason for me to get the 1080p and not the 720p of my TV was the contrast ratio, which was 20,000:1 opposed to the 15,000:1 in the 720p model. It is a nice feeling when you want to show people Blu-ray, and they are able to walk right up to the TV and be impressed.

[Blu Man]

I have a 720p projector. But 1080p is better.
