Our Score:


Yeah, yeah, I know: yet another bloody Panasonic TV. But actually, I'm not in the least bit apologetic. For it's hardly my fault if Panasonic has such a huge range of screens coming out this year for us to cover. And nor is my fault if Panasonic is more proactive than any other brand when it comes to providing us with test samples. What's more, today's Panny model, the TX-P46G10, is anything but ‘just another plasma TV'. For it's the first model we've seen that employs Panasonic's new NeoPDP technology.

NeoPDP screens are claimed to be the results of Panasonic going ‘back to the drawing board' in search of ways to significantly boost the performance of its plasma panels, with particular focus on its IC and panel structure technologies. And they include new phosphors and cell designs to boost the efficiency of each plasma chamber's discharge cycle, as well as new circuit and drive technologies to reduce by a staggering 50 per cent the amount of power needed to produce their pictures.

Panasonic has actually used this huge improvement in power efficiency to provide the option of achieving the same brightness levels as you get with last year's plasma screens while using far less power, or else using the same power used on last year's screens to produce far brighter images.

The fact that the NeoPDP panels are more energy-efficient than their ancestors will inevitably prove helpful in countering LCD's ‘plasma isn't green' mantra. But you know, much as I love our green and pleasant planet, I have to selfishly admit that I'm really more keen on the other benefit that Panasonic's NeoPDP panel should bring: improved picture quality. Or more specifically, improved motion performance thanks to a faster (0.001ms!) response time, better colour reproduction, and last but not least, enhanced contrast.

Regarding this latter potential improvement, Panasonic has actually stuck the ‘infinity' symbol on the TV's marketing blurb to describe its contrast talents. Admittedly underneath this symbol are the words ‘over 2,000,000:1' by way of qualification. But the bottom line is that the P46G10 should be serving up the single greatest contrast performance of any Panasonic plasma to date. In fact, it could even deliver black levels to better any rival TVs from any brand, including Pioneer's legendary KURO models.

You might think that all this fancy NeoPDP stuff would be innovation enough for the P46G10, but no. For the set is also Panasonic's first TV with 600Hz Sub-Field Drive Intelligent Frame Creation Pro technology. The show-stopping 600Hz figure included within that mouthful of a feature certainly sounds very impressive when you consider that Sony's only just cracked 200Hz with its much-vaunted Z4500 LCD TVs. But as we discussed when talking about a similar 600Hz claim recently made by LG's 50PS8000 plasma TV, the P46G10's 600Hz figure is actually derived not by increasing the refresh rate to12 times the usual 50Hz level, but by including in the frame rate calculation new image frames - or sub-fields - calculated by the TV to contain the necessary picture information to ‘fill in the gaps' between the real 50Hz frames obtained from a source.

Well done Panasonic.

But John, please don't insult the Pioneer Kuro TVs by comparing them to a Panasonic!!

Pioneer made their TV with a passion that Panasonic cannot hope to copy.

Pioneer made their best TV in 2 sizes with 2 models each (with a media box and without). That's it. The same panel used in all models - their best effort - nothing less.

Companies like Panasonic make several models - cheap ones and expensive ones. Not all of these are their best effort, are they? In fact, some have been delibrately crippled to justify their place at that price point.

Yes, I do own a Pioneer Kuro. And no, I will not be buying this Panasonic.

@ Prem, a little harsh don't you think?


April 1, 2009, 11:55 am


So you are admitting that you are willing to pay 3x times the price for the sake of knowing that nuts and bolts in your panel were screwed on by hand (apart from the fact that they weren't)? Man, you are the perfect marketing target.

I own 2 of Panny's excellent Viera plasmas, and i wish that their remotes were less plasticky and generally made better, but i'm not paying 2 grand to get a better remote.


April 1, 2009, 1:45 pm


the kuro may have the best image quality at the moment, but since they're apparently pulling out that tech won't be the greatest anymore, after a time. it's like how my littl vauxhall corsa could outrun an aston martin db5. i wouldn't be suprised if panny's top of the line tv walks away with an editors choice.

@Prem - If Pioneer were so passionate about the construction of their TVs, why did they decide to offload panel manufacture to Panasonic?

The fact is that Panasonic’s plasma manufacturing facility is amazing, and Pioneer couldn’t hope to make that kind of investment itself. I have been to the Panasonic plasma factories and I can tell you first hand that there is no one more capable of manufacturing top quality plasma panels, which is why Pioneer struck the production deal up with Panasonic in the first place.

I don’t think that John is at all misguided in comparing this panel to a Kuro, since any new development should be compared to the best in the market. It also doesn’t surprise me that Panasonic is making such huge leaps forward with its black level response, since I would be amazed if the co-op deal with Pioneer didn’t include some amount of technology sharing.

Yes I do own a second gen Pioneer Kuro. Yes I do love it. But it’s a sad fact that Pioneer will not be manufacturing TVs for much longer, and therefore other manufacturers will eventually surpass the image quality of my TV. That is, quite simply, inevitable.

"Yeah, yeah, I know: yet another bloody Panasonic TV. But actually, I'm not in the least bit apologetic"

Nor should you apolgise, I'd bet most people reading these reviews would give their right arm to be doing your job! :-) Shame you can't do an annual TR raffle to give all these away.


April 1, 2009, 3:30 pm

"Shame you can't do an annual TR raffle to give all these away."

That infers we get to keep them in the first place and I can assure you we seldom do.

Could you kindly consider modifying the features table. The text of the article suggests that there are both HD and SD Freesat Tuners (or at least one that is capable of both) and a Freeview tuner, but the features table doesnt expand Freesat beyond saying that there is one. It would be helpful for quick comparisons if this was clearer in the table and given the future plans for HD Freeview, would also help when this comes about.

Thank you very much

When do you expect to review the Z1, V10 or G15 series as I'm very interested in those as they hopefully come with Viera Cast technology for some internet sites vid streaming.

Thanks for another great review as well.

@Riyad - It's kinda sad that when I read the word 'inevitable' I can't help but read it in my head as Agent Smith.

Perhaps its sad too that I don't have to explain who I mean when on this forum.

Nah, screw it, that was a great trilogy. I'm beginning to believe!!!!

I have a 50" Panasonic Viera and Pioneer Kuro plasmas and whilst there is no doubt the Pioneer has the better picture quality I wouldn't say that the Panasonic was poor. There is always a compromise whichever you choose.

I agree that the Panasonic has the better user interface, remote and is quick to respond to button presses along with a great EPG. The Pioneer is slow to respond to button presses, has a terribly slow EPG that does not allow you to hear the TV audio while viewing and other such annoyances but it's picture is outstanding and for the pure visual experience cannot (yet) be beaten.

If you want a television with good picture and control over the programmes get the Panasonic but if you want the best picture and control over the image get the Pioneer and use an external tuner/DVD recorder/satellite unit.

@M7S - The Freesat tuner is both HD and SD. There are only two high definition channels on Freesat after all :)

To be fair I am feeling a little relieved that Panasonic have started to release panels getting close to the Pioneer quality. I eagerly await TR's review of the V10 to see if Panasonic has at last caught the mighty Kuro. After all if they mess this up what will people seeking the Kuro panel when they are no longer on the market.....and as they stop manufacturing them on April 11th....there won't be many left any time soon.

If Panasonic can deliver a V10/Z1 panel that equals or heaven forbid out performs the Kuro....straight out of the box and with little / no menu fiddling then I don't care what they do with the rest of their range.


April 2, 2009, 12:36 am

Hi Riyad,

When you say blacks approaching that of the Kuro's, I take it you mean the G8 Kuro's and not the G9 ones? Did you by any chance get a calibrated figure for the blacks in say cd/m2 or fL? I would be extremely surprised if they even came close to a G9 Kuro tbh! How does the shadow detail and off air SD performance also compare to a 5090 or KRP Kuro? What were your impressions of Veiracast - apart from just a few select websites, is there an option for selecting from a choice of widgets?

@Ed "That infers we get to keep them in the first place and I can assure you we seldom do."

Which is why I used phrase "shame you can't" as I figured there was very little chance of you keeping the review units. Still, keeping them or not the opportunity to play around with the latest gadgets leaves me green with envy although the work that goes into the reviews does not :-)


April 2, 2009, 3:37 am

@Baz - I didn't review this TV, John did, so I can't really answer your points. I know that I've yet to see a screen that compares to my G9 Kuro when it comes to black level response, but as I mentioned above, I don't expect that to be the case forever.

I hope the quality of this 46 incher extends to the 50 as I have just pre-ordered one.


April 3, 2009, 12:48 am

Oops - what did I start....???

What I'm saying is that whilst the Panasonic is a good TV, it does not beat the Kuro. There's more to picture quality that the blackness. There's motion, SD material, etc.

The Kuro is Pioneer's best effort. They didn't make a low spec model and then say after a few weeks, here's one a little bit better, etc. There's only one quality and 2 sizes.

You will note that I do not have the same passion for their disc spinners or other AV kit.

There's no one here who would buy the Panasonic over a Pioneer, if money was not the issue. That's a big IF I know but I'm just trying to say that the Pioneer Kuro is something very special.

Sorry if I offended anyone - not my intention. And no, I'm not the perfect marketing target - I just like the best (when I can afford it!).


April 4, 2009, 6:43 am

Sorry to be off topic - but it is about TV's

What does everyone think is the best freeview TV for not more than 𧹈 ? All round package more important than just sheer size....


April 7, 2009, 3:31 am

Hello Everyone at TR. I'm from the Netherlands and reading the reviews here with very much interest and enjoyment! I'm also looking at the 2009 Panasonic models. The thing, on paper at least, that I like most about it is the reduced power consumption, which John briefly mentioned. I was eager to read on, but soon disappointed not to see any hard figures to evidence these claims. Maybe it would be a good idea to elaborate a bit more on this topic, in these times where energy saving is drawing more and more attention.

Can't wait to see the V10 review, by the way. Keep up the good work guys!

WOW - got my 50" panasonic, it is awesome.


May 4, 2009, 4:05 am

I have a problem choosing between sony 46w5500 and the panny 46g10, read both reviews now confused even more. any advice would be appreciated


May 5, 2009, 3:50 pm

Would you please let us have your views on the sound quality and output, as I understand that the speakers are placed at the bottom of the set facing downwards?


May 17, 2009, 1:13 pm

Hey John/Riyad. I have a bit of a dilema. I'm stuck between the choice of buying the Samsung PS50A756 and the Panasonic Viera TX-P46G10.

I can get the Samsung a little bit cheaper and of course its 4" larger. (Mind you the couch is at 4 - 5m distance from where one of these baby's will hang on my wall)

My question is, Is the panasonic picture quility : black level/0.02s refresh frame rate/600Hz Sub-Field Drive/ Neo PdP/ etc...etc... worth going a tad more expensive but 4" smaller in tv size.... (even though I love the design of the Samsung, I would aways prefer quality of picture than quality of design)

Aaahhh the tyranny of choice... Could you put me out of my misery!! Oh yeah....great work on the reviews, best site out there!!

Some G10's in Denmark has been measured to output 24hz bluray with 60hz on the screen, which then produces jidder because of pulldown.

Anyone noticed anything about this?
