Panasonic TX-P42g15b

It's fair to say this generation of Panasonic TV's has had a bit of a rough ride, with model after model garnering lukewarm verdicts. We're sorry to say that the TX-P42G15B continues the trend.

It does kick off with a rather exciting specification, though. It boasts not only Freesat, but 600Hz sub field drive motion processing, internet connectivity and network streaming via its ethernet socket, as well as four HDMIs. It's one of Panasonic's high-end. NeoPDP plasma panels, too.

Impressive black levels

That panel certainly has its benefits. Play The hurt Locker on Blu-Ray and its recreation of blacks lends extra foreboding to the night-drenched streets of Iraq as the soldiers search for bombs. The Pana's insight means we see virtually everything, and when they open fire, muzzle flashes are realistically bright and punchy.

It's not all good news, though. Even on the "cool" setting, colors are warmer than they should be, with a touch of pink to whites tones.

Generally speaking, this isn't unpleasant, but on occasion it can add an unnatural vividness to skin tones. The other disappointment is that its 600Hz processing makes so little difference to motion: it's decent, but not as stable as the best on test.

Detail levels are marginally lower than the best when playing a Blu-ray, but the gap widens when you switch to standard-definition DVD the characters and sets of Funny People look a touch on the soft side, expecially in comparison with the Samsung. 

Having said that, the picture is certainly clean and stable, and black levels continue to impress.

When it comes to the Freesat and Freeview tuners, the result is as we'd expect: there's not much to choose between the two. A little extra control alongside HD content will ensure those with a satellite will opt for Freesat, but both tuners are respectable, if a bit over-exposed in colors  when pushed.

Like the rest of the performance, the Panasonic's sound is reasonable, if unexciting.  And, that's the best way to sum this TV up:  it won't annoy you, but it won't excite you too much, either. Panasonic fans will be hoping the company's next generation puts them back among the class leaders.
 

CES 2010: TVs, HD and 3D dominate

As predicted, the annual Consumer Electronics Show in Las Vegas 3D hogging the timelight, but there was plenty more TV tech to get excited about, too

The agenda for the year in AV was once again set at CES in Las Vegas, as all the big hitters in the industry gathered show off their wares and trumpet the technologies of the future.

Of course it's not all TVs and 3D (though it's fair to say that's a considerable chunk) so turn to p26 to get the lowdown on the top 10 technology titbits for the next 12 months.

Still, there's no denying that television dominated proceeding. The likes of LG, Panasonic, Samsung, Sharp and Sony all have a wealth of TV products on the horizon.

Expect the next generation of flatscreen of TVs to be super-slim yet ultra-connected, with wireless internet bringing apps for Skype and Twitter to your TV.

LED will continue to muscle in on traditional LCD screens, while OLED lurks on the horizon, and Freeviews HD will join Freesat HD in the world of non-subscription, high-def. Oh, and did we mention 3D? The screens and the content are on their way.

LG's new sub-brand Infinia will hope to enter our consciousness in the same manner as Bravia and Viera. The top-of-the-range LED series boasts local area dimming from sets just 23mm in depth, as well as 480Hz motion processing. Half of the staggering 70 TVs set for release will boast Freeview HD, while the LD360 will be LG's first 3DTV.

Panasonic's American range of sets was similarly well-endowed, with as many as 203 DTVs set to be released this year.

They'll be joined by LED-backlit screens, too. Panasonic has also grabbed a number of the engineers responsible for Pioneer's legendary Kuro range - promising news for its 2010 range.

Samsung will bring the world's first HD app store offering free and paid-for-TV applications. The initial raft will include apps for eBay, Facebook, Netflix and YouTube among others. 3DTVs and Samsung's thinnest ever sets, at 23mm, will also arrive.

Sharp, meanwhile, eschewed 3D in the main, focusing instead on the company's new QuadPixel technology.  Adding a fourth primary color to sets - "RGBY" - the TVs promises more than a trillion colors.

Last, buy by no means least, is Sony. There's a new "monolithic" design for a host of wi-fi enabled TVs, 75 per cent of which will have Freeview HD tuners. There'll be plenty of 3D TVs as well as sets with integrated BD and DVD players. It certainly looks set to be an exciting year in the world of TV...

Displays with local dimming system are the new frontier in Liquid Crystal devices, performing an amazing contrast ratio and the darkest black ever.
Do you remember when LCD televisions were looked down as the “poor relatives” around image reproduction, crushed by plasma models and by the good old cathode ray tube
Those times are technologically far away, even though not so many years have gone by. Liquid Crystal Technology has definitely filled the gap that was separating it from its competitors and at the moment it seems to have the weapon of choice to be the winner in the war on quality.
The ace up the sleeve is called “Local Dimming” and it works with a LED backlight.
It makes look old and tired not only the plasma devices (being the Crt TV out of the scene) but also the LCD displays begin to look not so fit anymore...

The technical aspect that anybody wanting to buy a LCD television is concerned about is most probably the contrast ratio, since it's clear that the higher it is, the better the performance.
To be precise, there are two kinds of so called “contrast ratio”. The first is the static contrast which is the ratio between the brightness of the white and the brightness of the black. It is a value that shows how much the liquid crystals in the panel are capable to block the light coming from the backlight lamp.
The second kind is the dynamic contrast, which doesn't only depend on the liquid crystals, but on the backlight too. As a matter of fact it is the ratio between the white calculated on the maximum backlight and the black calculated on the minimum backlight. This dynamic ratio is thus much higher than the panel static one.

Plasma vs. LCD

The common debate in the world of television these days is plasma vs. LCD and what is the better way to go. Well, it’s not real simple since both technologies provide almost the same results amazing color and crystal clear images, and a dizzying array of available sizes, but the truth is you are really taking about two competing technologies in which LCD seems to be winning the TV display war. They are technically very different technologies with LCD being rear projection style TV’s and plasma using natural gases which are excited by electric current to form the pixels that make up the picture on a plasma display.
