1080i vs 720p

[desertbird]

With the buzz about 1080p coming out now, There are some great deals on 720p HDTV's in the 50-60 inch range right now.
Now, for a few dollars more, I can find a 1080i set. Anybody ever notice the difference? Some of the HD stations broadcast it, (CBS, NBC, ABC, FOX) and others (ESPN) broadcast 720p. What's the skinny?
I ain't a baller like some of ya'll on here, so I ain't droppin G's on a 1080p Plasma right now. I will spend about $1500 for a nice LCD rear projection though. :crossx:

Pixel diffrents. Higher res on 1080p. Diffrents would be 720 lines opposed to 1080 lines. 1080 is better.

1080p with HD is the only way to fly. :)

720p for sports and fast action
1080i for movies and slower type material.
I would not purchase a 720p micro displays though, 90% of the 720p micro display do not convert 1080i to 720p correctly, leaving you with a DVD quality picture. And there are more channel transmitting in 1080i than there is 720p. I know this is going to ruffle a lot of feathers here, but here are two articles on how it works.

If 720p and 1080i are converted correctly, then YES.

[MR HARLEY]

If 720p and 1080i are converted correctly, then YES.
Converted?? Not familiar.
All my T.V.'s are 1080p hooked up to Dish HD boxes, and I could'nt be happier with the results, especially my locals and Espn.

I've seen this TV at Circuit City and Best Buy. Incredible picture. Also their prices were about $400.00 more. This company will drop ship to the house. Shipping a little expensive but probably worth it. This the 50". The 56" is $350 more and worth it. (2nd link)

When a 720p or 1080p display receive a 1080i signal (from NBC, CBS, KTLA, HDNet, HDNet Movies, Discovery HD, Universal HD, HBO, and some other channels) they don't always convert it to 720p or 1080p correctly. 1080i is two fields of 540 lines (2 fields of 540 lines of resolution make up 1080i) of resolution, instead of the 720p and 1080p displays to wait and received both 540 (1080i is true HD, 540 is not) fields to convert it to 720p or 1080p, it converts 540 lines of resolution to 720p, 1080p. So the 720p, 1080p display is only only converting half the resolution leaving you with a DVD quality picture, not true HD the way it is suppose to be.
Now those same displays get a 720p signal (ABC, Fox, ESPN and others) the 720p and 1080p displays look real good. Hope I did not confuse you.

I read some where that DLP TV's are not selling as good as the LCD TV's.
The sony sxrd is supposed to be the shiz for projection tv's.

Yes, the Sony SXRD has taken the LCOS technology and taken it a step further. Right now though, it is between the LED DLP technology and the SXRD technology. If the SXRD sets are made with the LED light engine instead of the light bulb, then that would be the icing on the cake. LCD's sell better because they usually are less expensive, but LCD sets have the worst picture quality.

Just ordered the the 32" 720i from Costco.com for $660 with shipping and tax. I figure if it sucks, I'll just use it for the tailgates or hang it in my garage. The 37" 1080i on Costco.com was $1299 plus tax and didn't want to spend that coin right now. :cool:

I have the 50" Sony SXRD with HD DirecTV and it is a damn good, clean picture...

[Chromegorilla]

C'mon...would ya rather have 1080 HP or 720 Hp....... :crossx: Need to put it in boat terms...more is better! :rollside:

[boatnam2]

i just put the 40" sony s series lcd in our bedroom with dish and i love the pic.i think i payed 1599.00.

That's what I have the "A" series 55" . Now I just need more HD channels out of Direct.

[desertbird]

OH yeah, now I am thouroughly confused. I have a failry good understanding of interlaced vs. progressive and the pros and cons of each.....well maybe not.
I think progressive is always better, as there will never be "combing" or "Flicker" then I am told that at 1080i, the resolution is too fine to notice the combing or flicker......
I guess my real question was, if I go with the 720p LCD (for the price of $800 less) will I be happy with the results from a 1080i signal?
Secondly, do most of you let the TV convert the signal to it's native value or do you use the Cable/Dish box to supply the converted signal?
I watch more CSI and DVD movies than I do football or golf, if that helps......
who's on first? :boxed:

[Parker Dreamin]

Just buy it at COSTCO and return it if you dont like it a year or two later.

[blown65]

I have the 60" SXRD with a HD-DVD player. LOVE the picture on it.
Actually when you look at it, the Samsung and the Mits side by side with the same feeds, for me it was pretty easy to pick the winner.

Progressive is better if you have better than 20/20 vision and sit real close to the TV. Even then it is hard to tell because interlace is refreshed so fast that it is hard to tell.
For $800.00 and if the display is smaller than 32 inches and sit more than 6' away, then I would say do it. Just remember, it is an $800.00 set so don't expect terrific results, mainly in color accuracy and and film smoothness, the contrast ratio probably will also be lacking and LCD is the weakest of all the technologies out there.
There is no longer any displays that lets you watch in its native broadcast signal/resolution, if it is a micro display (LCD, DLP, LCOS, SXRD, Plasma) it will convert it to its native resolution, which is 720p or 1080p. You can tell the cable box or Sat receiver to do native, but once it gets to the TV, the TV will covert it to it's natural resolution.
The only 1080i sets left are CRT displays, but nobody likes them because of there size, funny thing is though, they have the best picture quality out of all the technologies out there. All CRT displays are 1080i now, even if they say they can display a 720p signal, it converts it to 1080i, they do a real nice job converting it though.
Good luck with what ever technology you decide.

I was looking at the Mitsu 50' rear projection units, identical other than one was 1080i the other 1080p. Both had good pic quality to me but the 'p' seems to be slightly sharper. Was ~$800 difference between them........for an old guy like me I was leaning towards keeping some of my money. What do ya think Juan? I just run basic cable, no HD or any other fancy shit. :p

If you have the room, definitely a CRT/1080i display, nothing converts 480i/ analog broadcasting better than CRT displays. Micro displays do tend to be a little bit sharper and I am sure edge enhancement was probably turned on as well. I always turn that off and turn the sharpness down as the tend to display false lines and over saturate the display with noise.

[Cat & Mice]

Just to be clear
Best to worst
1080p
720p
1080i
720p is better then 1080i

[Jyruiz]

720p is not always better than 1080i, it all depends on what you are watching. When you're talking about MOVIES, Movies are filmed at 24 full frames per second. Which is to say 24p, ie Progressive. If you scan the movie to full HD you get 1920x1080p24, then to convert it to american broadcast standards which is 60hz you do a 3:2 pull-down and then splits up the fields into 60 fields per second which exactly converts the 24p to 60i, interlaced. This means that for all movie content, a 1080i60-signal will deliver exactly 1080p24 quality if you treat the signal correctly.
Now, I am not saying 1080i is better than 720p, but if the source is a movie, even if it isn't a movie, there's still more information in 1080i because 1080i equals to 2.073.600 pixels and 720p equals 921.600 pixels.
So it all depends on what you are watching, most of the time anyway.

Well...since you put it that way...
Dammit, someone just tell me what TV to buy if I watch sports and movies, use a cable box, want at least 50", and will sit about 18' from the set... :cry: :cry:

[TrojanDan]

Just buy it at COSTCO and return it if you dont like it a year or two later.
The rumor mill from "inside sources" says this will come to an end for all "Majors" at Costco. Costco is rethinking their return policy on all "majors" (i.e. computers, appliances, tv's, vcr's, stereo's - you know, all the crap in the front section of the store). If it goes in effect, it will happen Jan '07 so return that 4 year old tube tv now. :D All other stuff will have the normal return policy.

If you are going to sit that far back, I suggest something bigger than a 50" set. On the plus side, if you choose not to go with something bigger, then pretty much any set you choose will be fine. Hard to tell the difference when you are that far back, unless you have eagle eyes.

[Danhercules]

Roz hooked me up with a Samsung 61" DLP that is capable of the 1080. Its the bomb!!!

[ROZ]

720p is the minimum resolution in the "HD" range....
