Topic: Panasonic Plasma 2012

[barrister]

iirc, ang mga 50in plasma few years ago, resolution nila is 1366x768. Ngayon kahit mga 50in, if not full hd, 1024x768 na din. I wonder why, cost cutting?

Looks like Panny wanted to limit it to 2 resolutions.

They used to have 2 resolutions: 852 x 480 (EDTV or "Extended Resolution TV") for 42"; and 1366 x 768 (WXGA or "Wide Extended Graphics Array") for 50".  Both of them are 16:9 pixel ratios.

Next, they phased out the 852 x 480 for the 42" and replaced it with 1024 x 768 (XGA or "Extended Graphics Array").  This time, they had 3 resolutions: XGA 1024 x 768 (42" only); WXGA 1366 x 768 (50" only); and Full HD 1920 x 1080 (for all panel sizes).

I think it was in 2010 that they phased out the 1366 x768 resolution and also replaced it with the 1024 x 768 resolution.  So now, Panny plasma resolutions are cut down from 3 types to the 2 that we have now: XGA 1024 x 768 and Full HD 1920 x 1080.  Both resolutions are available in 42" and 50" sizes.  But any panel size larger than 50" always comes with a Full HD resolution.


=============================


For panel sizes larger than 50", you'd think that resolutions have nowhere to go but up.  ... Not.

Surpisingly, in 2012 Samsung came up with two 60 inch plasmas that are not Full HD --- the 60 inch PenTile panels of the 60E550 and 60E530.  It's more power-efficient, but expectedly produces an inferior picture.  What's more puzzling is that Samsung won't even tell us what the resolution is.  All they're saying is that it "reproduces FHD-like experience." 

http://ramsaysmarthomes.ca/info/Samsung%202012%20Panel%20Chart.pdf

The footnote reads: *Samsung’s Pentile Panel reproduces FHD-like experience utilizing sub-pixel rendering technology, making it 40% energy efficient over last year’s 59” comparable model.

http://en.wikipedia.org/wiki/PenTile_matrix_family

I've searched all over the net but I can't find any info as to why the pixel structure on the Panny X50 is different from their older 720p plasmas.  Maybe it's because no enthusiast seems to be interested in those low-end models.

I don't know if the Panny X50 is using PenTile displays.  It's a theory I have, but so far, I haven't found anything to back that up.

^Now that's messed up..  Kaya talon ka na din Sir Barrister sa VT30 bandwagon.

Maganda talaga ang VT30 sir, but if I get a green and pink issue, I think I'm going to regret it, especially now that we're so close to getting the ST50.

Somebody finally saw the green and pink on a 2011 model.  And he saw the same thing on 5 sets, no less:

I bought a 50VT30 a week ago but had to send it back for a refund because of the dreaded green and pink tint issue. Thinking that it was limited to my set, I tested 4 other panels of different manufacturing dates but all exhibited the same problem. It's a beautiful TV and I'm aware that there's no such thing as a perfect set but the color uniformity issue is just significant and something that I can't live with.

Also read this from the other thread, I think it's unfortunate that it has come to this.. Purchasing TV shouldn't come down to lottery where we're lucky if we can land a decent issue/(s)-free screen. Not to mention we are spending a huge fraction of our savings for this.

I for one, am a very happy VT30 owner. As I mentioned to you before in a PM, I saw the green tint during a FW update. But after watching a whole NFL game in HD, have not seen it since.

But yes, patience, more often than not, draws its own reward! Good luck sayo Sir!

I remember you said "green tinge" in the PM, so I assumed it was just a slight green tint all over, and not a prominent green blob in the center of the screen. 

Unlike yung kay sir Tonmeister, which I understood to be a real green blob.

But either way, if it's no big deal to you, then everything's fine.  After all, the 2012 panels are not perfect either --- they have their own set of issues as well.

Panasonic TX-P42UT50B Plasma 3D TV Review
By David Mackenzie • 25 September 2012 • Verdict: Highly Recommended • Typical price: £550



...Without any strong light to wash out the picture, the TXP42UT50B gave us a measurement of 0.009 cd/m2 on both a full black screen and on an ANSI checkerboard test chart. That’s equivalent to the company’s VT50 flagship plasmas which cost many, many times more than the UT50. This is extraordinary performance for a display of this price.

...Before we reviewed the Panasonic TX-P42UT50B, we had the idea that the UT50 series’ picture quality would be essentially the same as the excellent ST50′s, factoring in the omission of the antireflective plasma screen coating on this cheaper display. That assumption turned out to be right on the money: provided you’re in a dimmer environment where its deep blacks won’t be washed out by light hitting the screen, the TX-P42UT50 produces the same outstanding picture quality, and in the right environment, it’s frankly hard to tell it apart from the very best.

Panasonic TC-P50X5 review
By Ty Pendlebury

... This is the only Panasonic plasma I don't recommend. In fact, much like many of the company's LCD and LED TVs, I encourage you to actively avoid it.

... After hogging the headlines of our plasma TV reviews all year, the company's luck had to end somehere, and that's here. ...The Panasonic, unfortunately, is mediocre. After good performance from the U50 I was curious to see how deep the rabbit hole went, and it seems in this case not that far -- it's more of a pothole here in Panasonic's "X" series.

[DTNS]

the X series is really the one to avoid.      the UT, ST, and VT are good choices though. 

[barrister]

On the cnet First Look video, Ty Pendlebury says "this is the worst plasma I've seen this year." 

He recommends the Samsung 51E450 instead of the Panasonic 50X5 (both are 720p plasmas for 2012).

I agree with him. I've seen the Samsung E450 series plasma, and I think they look decent.

It's the same problem that's in the X20 and X30 models.

[barrister]

Pendlebury mentions pixel structure on page 2:

Like any 720p plasma at 50 inches, it can be possible to see pixel structure depending on your seating distance. At a distance of 8 feet it was easiest to discern the vertical structure on the X5 over any of the other 720p TVs in the lineup, which included a 50-inch Samsung and a 42-inch LG.

Pixel visibility at 8 feet is unacceptable, since that's the viewing distance of the average living room.

On the old 50 inch 720p plasmas, pixel structure was invisible from even 5 feet away.  For the 2012 720p Panny, not anymore.

And note that Pendlebury says the "vertical structure" was easiest to see on the Panasonic X5, compared with other current-year 720p plasma TVs.  This is what I've been talking about for months.  That "vertical structure" is visible as fine vertical stripes, especially on white areas of the picture, and they are visible even from 10 feet away.


=======================================


Also, Pendlebury says the green error can't be corrected:

Looking at the RGB color chart (of which I've added a screenshot below and which is available in full at the bottom of the page) you can begin to see where the green problem comes from. See how that little green dot is way out in.. well... Green-land? That's bad, and unfortunately it's impossible to correct with the minimal controls this television offers. The TV's grayscale is another major contributor; while OK in the brighter areas, it's noticeably green in middle and darker areas.

Our 60st50 as reached Manila na, 1 more week or less it should be home for testing........... Woohoooooo!

Time to get me a pch400, kelan kaya release nyan?

[barrister]

Avforums (UK) member "mtunreal69" suggests a reason for the vertical bands on the Panny 2012 plasmas.

He thinks the bands are caused by non-uniformity in the coating process of film filters.  This rules out firnware updates as a possibe fix.

[timber715]

one thing I know I will not be doing... look for things that would make me disappointed with the purchase. Drawbacks of direct purchase is warranty is an issue

Anyone knows the power consumption of the 42st30. Im getting different values online. thanks

Panasonic TX-P42ST50 review

[stockHT]

mga sir i saw the green/pink issue above but I cannot fully understand and picture out the problem.

Although kinakabahan ako kasi I ma encountering issue with my panasonic 42ST30.

First my connections are:
PS3 -> AVR -> ST30
Measy -> AVR -> ST30

While playing PS3, bigla na lang nagbliblink at may pixelized gray (with other small colors) in the screen tapos mag wawarp then mawawala ang picture total black pero may audio, minsan babalik, minsan hindi. I tired to move the input selection of the AVR and move it back to PS3, sometime bumabalik sometime no.

Same happens when connected to my nmt measy x5.

Also, it keeps on going back to balck with "HDMI" on top left. Parang nagpapalit ng basa ng resolution.

is this a known issue?

[barrister]

No, video dropout is not a known issue for the 2011 Panny plasmas.
 
Look for an HDMI problem.

[halvert]

^hindi po kaya nagalaw lang yung hdmi cable? minsan ganyan nangyayari sa akin pero pag ginalaw ko lang ng konti yung hdmi connection sa tv, ok na.

[Allan_2180]

also happened with my 42ST30 before, connection was PCH->ST30.
ung video signal coming from my PCH-A200 nagiging grainy at nagkakaroon ng
speckles na ngra-rainbow sa edge ng mga images,
nagpalit lang ako ng 400 pesos 1meter na HDMI cable from ACE Hardware, so far di na uli naulit kahit pa nagbago ako ng connection PCH->YAMAHA AVR->ST30.

[stockHT]

i tried to change the HDMI cable from AVR to TV with my handy CDR king HDMI cable. Last night played 3 games of 2k13 and 2 episodes of tv series walang issue na lumabas.

unfortunately this afternoon i tested it again, played 2k13, wala pa sa 3rd qtr lumabas na ulit yung issue.

[Allan_2180]

na-try mo ba na i-connect muna ng direct sa ST30 both media player and PS3?
AFAIK sensitive ang HDMI cables sa bending at pag madalas tinatanggal-kabit sa HDMI ports.

-posible na HDMI Switching ng AVR ang nagca-cause ng video dropout sa ST30?
-posible na may sign of wear na ang mga HDMI Ports.
-posible din na nabend ng matindi HDMI Cable at nagbago impedance ng wires sa loob kya
nawawala na sa timing ang signal pgdating sa Input ng ST30 causing drop-out.

Duda ako sa CDR King HDMI cable mo sir.
 
Chambahan lang pag CDR King HDMI.  Minsan OK, minsan hindi.

sir will do troubleshooting this weekend and update you all.

thanks for the inputs.

[Kier]

available na ba sa mga stores natin ang 42ST50? how much?

[barrister]

available na ba sa mga stores natin ang 42ST50? how much?

Wala pa sir.
 
Pag meron na, siguradong may sariling thread na dito ang model na yon.

[DTNS]

^ would you still recommend getting a 42ST30 or 42VT30 now, even though the ST50 and VT50's arrival in our market is imminent?

[Verbl Kint]

Duda ako sa CDR King HDMI cable mo sir.
 
Chambahan lang pag CDR King HDMI.  Minsan OK, minsan hindi.
 

They either work or they don't.  Best tested at the store before taking home.

[Clondalkin]

If I were in Manila, I would have taken the effort to look for a goooood VT30.  That price is definitely worth the try, at least.
