1920 X 1080i or 1080p....as I understand it...if 65" plasma has pixels of 1366X 768 is HD? Does it take advantage of Blu Ray, HD DVD properly? This directly relates to B&O's BeoVision 4. Yes very expensive and better ones out there, I guess. But wanted to ask the question as the dealer kept insisting it would do full HS of 1080i....is this not the same as pixel count. Am I missing something here?
"1920 X 1080i or 1080p....as I understand it...if 65" plasma has pixels of 1366X 768 is HD?"
A quick rule of thumb, as it was explained to me a long time ago. In your example '1920x1080', look at the '1920' number/position of it as the number of interlaced count the display can produce, eg 1920i or 1080i. Look at the '1080' number/position as the "progressive scanned" pixel count the display can produce, eg 1080p or 768p.
To answer your question, the 768 does fall above the 720p figure to constitute HD. So, yes the display can produce a HD 720p signal in true HD.
"Does it take advantage of Blu Ray, HD DVD properly?"
As long as the number is above 1080, then it can display the 1080p HD signals BluRay and HD-DVD can produce. As for the display you mentioned, the answer would be no, because it can only display a signal of 768p or below.
"But wanted to ask the question as the dealer kept insisting it would do full HS of 1080i....is this not the same as pixel count. Am I missing something here?"
The dealer is correct and so are you. The mentioned display (1366 x 768) can handle the 1080i HD signal. This is the pixel count, yes. However, it can not handle the 1080p signal of BluRay and HD-DVD because the second number is not 1080 or above.
I hope this makes sense and explains things alittle better.
Screens are a variety of sizes. All the plasma and LCD etc screens with a pixel count of 1080 to 1380 or so across and 750 to 1,100 up/down are 'native 720p or 1080i" Remember 1080p is TWICE the bandwidth of 1080i. And that 720p is about THE SAME bandwidth as 1080i. To START using 1080p the tv MUST HAVE enough pixels.. This STARTS at (a minimum!) 1920x1080. You could have lots more pixels and still be in the 1080p ballpark, but not less. Anyway, all this is still up in the air as very few TVs and players actually transmit the 1080p data. Between HDMI1.3 and it not even being implemented properly yet, and almost NO screen acepting a true 1080p signal from a player... It is still a total mess out there. I personally do not want to bother with HD until this mess is eventually cleared up (at LEAST two more years) I have my 720 native res Plasma, and my Denon 5910 DVD player via HDMI. I get decent picture quality. Eventually the stuff being manufactured will have to connections and the stability to be worth investing in it. But in the two year time frame, we may go another step up anyway, doubling the bandwidth yet again. Right now buying into 1080p is gonna get you only half of what you expected. (Unless you are using a Playstation 3 as your source??) and you have a screen with a 1080p inputs..HAH HA HA hah ha.....
While I share some of your dismay at the complicated HD market, I strongly disagree with your deduction from these issues.
First off there are too numerous to list sets that DO accept a true 1080p signal, all Sony's 1080 TV's do, as do their front projectors. Pioneer even has 1080p plasmas that yes accept a true 1080p/24 signal.
As for sources that output 1080p, perhaps you've missed the bandwagon..... Your DVD-5910 can even put out 1080p (and is pretty good at it as well I must say having had one for some time now) and many other DVD players scale to 1080p as well, not to mention Blu-ray and HD DVD. If you think these are 'lame' formats and waiting for a side to win, you are losing out on amazing pictures that dwarf anything else you can get to display on any set, the new Bond flick 'Casino Royale' sold over 100,000 copies in Blu-ray in only a few weeks..... I know I onlu bought ONE so there are obviously many more folks out there with these players.
For my money, if you are buying a new display of any kind and you DON'T buy a 1080p capable set I think you are foolish as you will want this feature before your TV dies or you want to buy another one, oh and you don't need HDMI 1.3 to transmit 1080p, you can easily do it with 1.1.
Sorry for the rant, but I am going to go watch something on my 1080p capable 70" Sony on one of the five sources I currently have that output 1080p.......
I agree with Kennyt above, having just acquired a Sony 46" 1080p LCD that puts out a magnificent picture. Even in 1080i it makes my 3 yr old rear projection HD Hitachi Director Series look like something from the 60's!
Ya' Kennyt got it. The new Toshiba X2A and even the ps3 actually output 1080p--(I have the older X1A). I have the Sony Ruby and the pq; even with my older X1A is better than my TWC-hd feed. I know we all have different levels of enjoyment/ desires, and budgets.---Pretty much anyone whom is a videophile with the funds has one of the new displays and one of the new format players.---LG just came out with a player that does BD and HD-DVD.--(BD= blue ray) So, as they say you can get into the game and run with the big-dogs or just sit on the porch.---I rent from Netflix--they rent both formats---same price as renting standard dvds.---
HD is 720p or greater resolution, so yes, a 1366 x 768 plasma is a high def TV.
Plasma, like LCD, LCos, and DLP, are fixed pixel displays so they must convert any incoming signal to their native resolution before they can display it. And, if the input signal is interlaced rather than progressive, the set must also deinterlace the signal.
So the plasma in question will have to make a small scaling adjustment to expand a 720p input to display at 768p. In the case of 1080i / 1080p input, then the TV has to throw away some of the information as it scales down to 768p for display (and for 1080i it also has to deinterlace).
HD on TV, cable, and satellite is either 720p or 1080i.
For the two high def DVD formats, the data is stored on the disc as 1080p/24. Please note, this is not the same as 1080p/60. If the source is 1080p/24, then it can be transmitted as 1080i with no loss of information, provided the TV correctly deinterlaces the 1080i input.
Apparently, not all TVs deinterlace correctly. So, if the TV accepts a 1080p input, and you have the ability to send it a 1080p signal like some of the new high def DVD players, then its possible to see an improvement in picture quality. But the improvement is due to a problem in the TV's deinterlacing, not in the fact that it's being sent as 1080i.
All of the above does not apply if you have a true 1080p/60 source, which is different than 1080p/24, but I am not aware of true 1080p/60 sources unless the gaming systems have that (TV is 720p or 1080i, and movies are 1080p/24).
Thanks all. Much more clear to me. I already have a Pioneer plasma 50" that is capable of 720p/1080i...and the vaunted Denon flagship AX1 DVD player. Just bot a house so wanted another set for another room, or more buy an upgraded set and move this one to the bedroom which is fairly large too. It seems to me that I should stick with looking at 1080p capable screens. The Denon is capable of upscaling to 1080P and besides, I think I can take my time with Bluray/HDDVD and see it how it goes in terms of software & new player models availability...but given need to purchase a display anyway, might as well get one that is 1080 ready so as not to regret it down the horizon.
A shame in way. The B&O set up looked really kool. Indeed the motivation for me was actually their speaker set up, Beolab5s. I like that they are not placement sensitive having their own sensors to auto adjust,and all speakers have inbuilt amplifcation so that a power amp is not necessary+ no sep sub needed as the BeoLab 5s have in built subs. Plus they just look interesting. But the problem is their connectivity: to use this system u have to get their processor as B&O uses their own proprierty connectivity methods for the processor/center speaker/display. (the Beolab 5s are not an issue, its the rest of the set up that is)
A sep question. So let's say I get the BeoLab 5s which should really driven via digital inputs (intern DAC/amplification/room equalization)....do think there is way to hook it up with a pre-pro/pwr amp so that the rest center/rears are driven by analogue connections?
Regarding "480p is part of HD. i.e.Can't do 480p without a hdtv", 480p is EDTV, although I don't know if they still sell EDTV sets. But I do agree that a regular TV cannot do 480p, only 480i. You need either EDTV or HDTV to display 480p.
Absolutely agree with Elizabeth. That is why I have still have a Sony HD CRT that can acommodate for a variety of signals. The pixel issue is a big problem until standards converge. If you ever tried using the wrong resolution on a computer LCD screen (i.e. other than the native pixel resolution) then you will know what I mean - it goes all blurred. This means an LCD or a plasma will have an OPTIMUM input signal resolution and will not be as good for signals that do not match this OPTIMUM resolution.
If you still have many DVD's and still watch ordinary TV channels then an EDTV with a native resolution suited for DVD's may be your best choice in the interim (until old signals have disappeared and only 1080p exists)
Downscaling High Def 720p to DVD quality works well. Upscaling ordinary TV signals (less than DVD quality usually) to 720P or 1080P may actually look worse than ordinary TV!
