Amazing color reproduction

The incredible black reproduction of a Panasonic High-Definition Plasma TV results in impressive contrast and beautiful, natural colors. So you'll get warm, accurate skin tones, gorgeous greens, breathtaking blues and vivid reds. For color that's as rich and bold as life itself, look to a Panasonic Plasma TV.

Consistent brightness from any angle

A Panasonic Plasma combines anti-glare and anti-reflection technology with the natural light-emitting properties of plasma, to give you a super-wide viewing range with a crisp, beautiful image from almost any angle.

Smooth, graceful motion

When you're watching sports or movies with fast-motion graphics, you want a TV that can keep up with the action. With over 900 lines of moving picture, self-illuminating plasma displays eliminate afterimages in fast-action scenes. So whether you're watching a sporting event or an action-packed movie, you'll always get the most impressive viewing experience possible.

1,000,000:1 Contrast

The Panasonic's Real Black system (a pre-discharge suppression system) and improved panel production processes combine to reproduce outstanding blacks with superb contrast. Each image is richly expressive, from bright scense, like scorching desert landscapes, to dark cave scenes. Compare the image produced by conventional HDTV on the left to the Real Black image produced on the right

More Colors

Viera HDTVs support the xvYCC color profile (Extended YCC Colorimetry for Video Applications), or "x.v. color" for short. Standard RGB color space allows the display of a portion of the colors that are viewable to the human eye. The next generation "xvYCC" color space actually offers  an available range of colors that exceeds what human eyes can recognize.
  • Next-generation "xvYCC" color space supports 1.8 times as many colors as existing HDTV signals
  • Lets HDTVs display colors more accurately
  • Enables displays with more natural and vivid colors

deep color eliminates visible color banding

Deep Color

Where x.v. color expands the available range of colors your HDTV can display, Deep Color increases the number of colors your HDTV can display within that range, for smoother transitions from color to color.
  • Lets HDTVs and other displays go from millions of colors to billions of colors
  • Eliminates on-screen color banding, for smooth tonal transitions and subtle gradations between colors
  • Enables increased contrast ratio
  • Can represent many times more shades of gray between black and white.


Viera flat panel HDTVs interact with an array of high-definition devices and services, making it easy for consumers to access and enjoy content as never before. As of 2008, Viera Link is compatible with Onkyo and Yamaha home theater systems.
SD Cards Videos and stills recorded on SD cards can easily be viewed via the SD slots on Panasonic Blu-Ray Disc players and Viera HDTVs.

Long Life

Panasonic plasma panels are rated to last 100,000 hours, which is about 30 years of regular or 11 years of non-stop usage before the brightness of the display is halved.

Blu-Ray disc player

Get Full HD with Blu-Ray Disc Players

A Panasonic 1080p plasma television is able to render 1920x1080 pixels, but standard DVDs have a resolution of just 720x480. Blu-ray discs output true 1080p High-Definition resolution and have a storage capacity ten times greater than standard DVDs, so no pixel gos to waste.

Price was a significant contributor to my decision to buy this TV. Conversations with tv-guys made me think that I needed to pony up for a 1080, but I just could not justify the premium over the 720p. Now that I have it, I am glad I saved my money. The picture quality is great, both in high def and for normal (low def?) viewing. Whenever I have guests and the TV is on, they are blown away by the quality and ask my questions about it.

I also like the anti-glare screen. At first I was a little concerned that the anti-glare picture would look "dull" compared to your average plasma, but that is no longer a concern - it looks great.

Another big plus for me was the appearance of the TV. Like other Panasonic models, this TV is sleek. Vizio and other manufacturers seem to incorporate larger speakers that look clunky in comparison. The size of the tv relative to the picture size is great - looks nice on the wall, and doesn't take up any more room than it needs to.

In fact, the reason why I am writing this review is because I am going to buy another one for a different room in the house. Panasonic has definitely won my repeat business with this one - I think that says it all.

You really can't go wrong purchasing this TV. Don't base your decision directly on the Cnet review and instead head over to AVSForum. You'll find a 80+ page thread with numerous reviews done by experts in the field. All of which are very positive and explain why CNet's review isn't too reliable.

Unlike Panasonic's earlier model, the 77U, this TV has an excellent picture right out of the box. There's no need for an expensive calibration or messing with service menu's. I've found my favorite settings, thanks to someone on AVSForum, is:

Picture Mode: Cinema
Picture: 84
Brightness: 40
Tint: -2
Sharpness: 50
Color Temp: Warm
Color mgmt: off
x.v.Color: off
Video NR: off
MPEG NR: off
Black Level: light

You'll find a ton of other settings there too so just do a google search.

This TV also seems very reliable. Out of over 3000+ posts I only saw maybe three that were returned due to a serious failure. (All of which were promptly replaced/repaired) Panasonic also has a really cool warranty service called "Panasonic Concierge". You can schedule service calls online and you'll be contacted within 24 hours. You can also call or chat online with a rep if you've got any questions. Another great thing about them is that if your TV fails and they have to take it away for repair they give you a loaner TV! I sure wish I had that option with my old Philips.

I was first considering purchasing a Samsung LCD but decided to see both first hand in the store. After adjusting the settings on both TV's the Samsung had a very unnatural and bright image while the Panasonic looked as if you were looking out the window.

I spent a few months reviewing plasmas and lcd's both in the big box stores and online. I watch a lot of sports, and the lcd's still have the motion blurring problem (except the expensive new ones). For me, that narrowed it down to the plasmas. Like others have said, the Panasonic's stood out from the rest of the plasma's (except for Pioneers, but they are almost double the cost). In terms of 1080 and 720 plasmas, I could not tell a difference between the two in 42". Maybe a little in the larger sets, but not in this size. Not worth the extra cost IMHO. So, I finally took the plunge on Panasonic's 720 42" when the price dropped below $1000, no tax, free shipping. A great deal for a TV that has been on the market for less than 2 months.

Delivery on the TV was fast (about 5 days early). They called a day ahead and delivered it within 1/2 hour of their estimated arrival. They made sure that the TV worked, and offered to take away all the packaging material. A+.

The TV was a snap to set up--10 minutes. The first thing that I noticed was that the color contrast is excellent, even on SD- much better then our 6-year-old Toshiba 27" tube TV. The clarity varies by station- a function of the channels, not the TV. SD = A-

The picture quality really excels while playing DVDs through component video. Deep rich blacks, vivid colors. The "Planet Earth" series looks incredible. We have not hooked it up to HD yet, but I'm sure it will be even better. A+.

A nice feature is that the TV remembers your settings for each video input. I.e.--we programmed a different color contrast for broadcast TV and DVDs and it stores each separately. There are more than enough ways to adjust picture quality to really fine tune it.

I bought the prior year's model, delivered in December of 2007. The picture is now flickering and going completely black for about half the time. I'm in contact with Panasonic to have this resolved, under the one-year warranty, and I will follow with an update on how well this goes.

Regardless, it is annoying to have what otherwise is a splendid product apparently needing replacement in less than a year.

I promised a follow-up. Panasonic was *very* responsive. I filed a request for service at their online site. Within 24 hours, they contacted me to arrange a service appointment. The service person arrived when arranged, replaced one of the video boards quickly and without charge. It is possible that the problem was not with the board at all, but simply a cable connector that had not been seated properly at the factory. So, in all, a very good experience with Panasonic -- prompt response, no hassles or arguments for this repair service under the one-year warranty.
