this confirms the fact that normal/cheapo lcds with ccfl backlight are lacking in pq.. Vibrant lcd colors doesnt mean good pq. Dunno how many proponents of lcd actually have led backlight lcd tv?


Added on December 28, 2008, 1:54 pmas for blooming fm led backlights becos insufficient led cluster points due to cost and signal processing. Usually only got 128 points. The top end ones use over 1k points. Dunno how much though.

I've always preferred plasma, but the new LED backlight LCDs really give a strong fight to the plasmas. CNET is saying this technology almost reaches the Kuro's black level, and sometimes wins over in certain scenes. This LED will be turned off automatically in black areas and gives almost perfect deep black. The only issue is the number of LEDs may not be enough to turn off at the smallest pixel area, giving "blooming" effects when a bright object appears within a black background.

But now, there are only 2 LED backlight LCD TVs that I know of, a Sony which costs RM27k and another brand at really attractive price, but it's a Samsung which I'm not really favor off. They ranks at number 1 and 2 respectively for LCD TVs at CNET.

Is the Panasonic TH-PY800H really discontinued? The US version of this model is at second place in CNET ranking for plasma TVs and received the Editor's Choice tag. The newer TH-PZ850H PY locally is at lower rank because of inaccurate color reproduction. But both of them have flicker issue for 24p playback though.

correct me if i'm wrong, but i was told by several salea agent that those Panny G11 plasma with 5 year warranty all "made in Japan" - with the exception of pv80, assebled in s'pore. hmm.gif

Second, isnt the Py800 and py850 is among the recent full HD by panny?? Py850 having more extra feature than py800 e.g. RGB cinema colour??

Are those two really bad in term of PQ - i know kuro is alway no 1. But to say py800/py850 is not good than we have limited choice for plasma - samsung anyone?? cry.gif cry.gif

I didn't say the Panasonics aren't good. In fact PY800 is my choice because I just can't afford the Kuro models of the same specs. PZ800 (or PY here, but without the THX) received an Editor's Choice tag, and is at number 2 in the list, second only to the Pioneer Elite Kuro PRO-111FD. The PZ850, however, got some color issues even though still better than many other brands.

CNET's Ranking:

Plasma TVs
LCD TVs

And of course, reviews and ranks are just guides. They've used specific testing tools (HQV) as well as real source (blu-ray, etc) for the reviews and presented the results, so it's quite useful. But I've also seen the TVs in action, I love the Panasonic plasmas so much, but the Samsung LED backlight LCD is not bad too.

But I keep hearing that the PY800 series will be discontinued, they'll only focus on PY850 now.

The Pioneer's plasma panel factory has been shutdown. The 9th gen Pioneers will be using the plasma panels from the Panasonic factory. Please correct me if I'm wrong.

nothing wrong if they watch mostly DVDs and Astro.. it still gives a very good PQ compared to LCD for these 2 sources..

besides, if you concern about PQ quality, what source do you have? how Blu-rays disc so far?

Then, what say you about Pioneer award winners Plasmas. e.g. the 42in Kuro 428xg also is 1024x768. Does pioneer tried to con the critics and various magazines (including the lame as me and you) that it is "HD" ready but not HD. and yet managed to bit the crap out of every contender in the same class or above and currently hold the best PQ in flat HDTV... rclxub.gif rclxub.gif rclxub.gif If they purposely tried (to con people), then I'm conned all the way (up to my a****). thumbup.gif thumbup.gif

Like i said ealier in my previous post, the most important thing is PQ. All the pixels, connections, sizes, are add up bonuses. Hey, correct me if i'm wrong - you buy tv for watching or for what..?? I dont mind missing the 5% around the edges of the screen in 1080 resolution, or not 1 to 1 mapping. As long as the main characters/scenes/action occurs in the middle - that's the directors intention anyway, delivered through cinema/life-like quality - thats the reason to buy and watch tv. whistling.gif whistling.gif

Actually, I'm just saying kena conned by people who tell them to buy 42" non-HD plasma. Actually, why not
buy 50" plasma. The 50" PV80 is 1366x768. If wanna buy PV80, just buy the 50" one la.... wink.gif

But there's really big difference between 720p and non-720p. Go check out yourselves.

You are right. In the near future, pioneer and panasonic will use the same panel (from panasonic). PY800 and PY850 50" confirm coming from Japan factory. With the current price, I believe it is very attractive. I think if panasonic selling the next rev at lower price might not from Japan anymore (cut cost!)

If you use HTPC, 1:1 pixel mapping is a must and Full HD is useful. The font will be super sharp compare to non-HD model. If you purely talk about movie, then depends on sitting distance. Sit nearly and you can still see the edge is not as sharp as full HD tv (especially curve is not so smooth).

That's a lot of bold statement coming from someone who I presume doesn't even own a LCD TV or Plasma. There's a few things going on here.

The two HDTV resolutions are 1280x720 and 1920x1080.

First, manufacturers use the term "720p display" in their marketing literature loosely and incorrectly. These days, they tend to use it for anything that isn't a "1080p display". So let's put that one to rest first.

The native resolution of a 1366x768 panel is not 720p. If anything, it is 768p, since all input is scaled to the 768 lines. But, of course, 768p is not a resolution that is used in the source material. Only 720p and 1080i/p are used. We should count 480i/p also, for SD material and DVDs.

In the case of plasma, it is fiendishly difficult to make plasma panels with small pixels. This is why 1080p plasmas are so long in coming and why 42 inch plasma panels are 1024x768.

How can 1024x768 be HD, you ask. Many dozens of people have asked that over and over here in the forum. The answer is, the Consumer Electronics Association has decided that any display with at least 720 lines can be called an HDTV and have the logo. There is some basis in fact for this because the human eye is more sensitive to vertical resolution than to horizontal resolution. This has been taken advantage of for years in NTSC because the horizontal resolution of NTSC is really poor. It is also taken advantage of in so-called HD-lite where the video is resampled to 1440x1080 on things like satellite, or maybe even shot with a 1440x1080 camera instead of the 1920x1080 camera you thought the network was using, and you probably didn't even notice.

We have had intense wars about whether that CEA definition is legitimate. Believe what you will, and if you don't think 1024x768 is HD, buy something else. Vote with your wallet. Simple as that.

In the case of LCD, it is difficult to make large pixels. This is one reason why 1366x768 has been used. Also, please do not forget that a lot of HD is in 1080i, so 1920x1080 has to be downscaled to 1366x768. Conversely, 1280x720 has to be upscaled to 1366x768.

To those who say, but wouldn't it be a good idea if the panel were 1280x720 so at least one of the resolutions wouldn't have to be scaled, I say nope! For one thing, you'd be downscaling 1920x1080 all the way down to 1280x720, so you'd lose a lot of resolution on the very format that is supposed to be giving you lots of detail, which is also what most channels broadcast in. For another thing, the extra resolution is really helpful on things like diagonal lines, where you can smooth out the line. If you were in 1280x720 on a 32 or 37 inch display, you'd probably be complaining that the display looks all blocky and pixelated because the pixels are just too big and the diagonal lines have too much stairstepping.

Turns out you can get 1280x720, but you have to go all the way down to 22 and 23 inches, where it works nicely.

Oh, and one other thing that comes up over and over again. The resolution of 1080i is not "540p", it is 1920x1080, dang it. If you were to shoot a still life, you would have 1920x1080 worth of pixels. It's simply that you have to wait 1/30 second rather than 1/60 second to get all the pixels. If it's a live shot. If it's film, it was shot at a mere 24 frames per second, so (inverse telecine, 3:2 pulldown, which is actually reverse 3:2 pulldown) done correctly gives you back your movie.

Do you really have to state the first line?

Anyway, good information there. But as a perfectionist, I would like to see pixel as it is.
So I would rather have 1366x768 with 1:1 pixel mapping. But if not, then I rather have
more pixel than 1024x768.

And 1080i eventhough is 1080 pixel, but its interlaced. In reality, its not perfect 1080p.
You know 1080p is nicer than 1080i.

If your eye can't differentiate, then I can't blame you. There's big different
between PV80 42" and PV80 50". Pls don't compare between your LCD and Plasma. wink.gif

1080i60 with proper pulldown flags inserted can recreate 1080p24 (in slow or still video scenes)
for fast moving scenes, there will be missing information..
of cos advanced motion adaptive algorithms in powerful deinterlacers (better than those built into LCD/plasma HD TVs) can be used to close the gap to rebuild 1080p24 but never 100% due to time differences between interlaced frames

Thank you for your elaborated explaination. It was an educating post.

For me, I'm just looking for the best PQ display to watch movies - day in, day out. At the moment, plasma is my choice. Being contemplating the kuro 428xg or panny 42py800 - cause as u said, my watching distance is merely 4 meter (max).

For other purposes that require a "certain" monitor with "certain" capabilities, i will look for that "certain monitor". I dont really believed in the "ALL-IN-ONE" gadget - something has to be compromised in order to keep all the features, hence, it looses some..

So, help me to decide which to buy - Kuro/Panny

Next, point me to the best price/deal.. thumbup.gif thumbup.gif
