CNET editors' take
- Published on: 09/06/2007
When it hits stores in a few days, the TH-42PZ77 will be the cheapest 1080p plasma.
(Credit: Panasonic)Despite the fact that the benefits of 1080p native resolution are difficult to discern at the 50-inch screen size, let alone 42 inches, Panasonic has to keep up with the LCD competition if it wants to maintain spec-sheet parity in the eyes of comparison shoppers. That's probably the main reason why the plasma powerhouse announced two new, lower-priced 1080p models today at CEDIA in Denver: the 42-inch TH-42PZ77 ($1799) and the 50-inch TH-50PZ77 ($2799).
These sets trim $200 off the list prices of the formerly least-expensive 1080p Panasonic plasmas, the excellent 42-inch TH-42PZ700U and the ever-popular TH-50PZ700U, making them the most affordable 1080p plasmas on the market, and strongly price-competitive with similarly sized 1080p LCDs. Here are some more items from the press release:
Panasonic TH-PZ77 series key features
- 1080p native resolution
- Two HDMI inputs
- Antiglare screen coating
- SD memory card slot
- September release date
The most-notable item on that list from our perspective is the antiglare coating, which is the same magical stuff found on the screens of the lower-resolution TH-PX77U series. Don't confuse it with the "antireflective" coating applied to the screens of the more-expensive TH-PZ700U and TH-PZ750U series; Panasonic's antiglare coating, if it performs as well on the PZ77s as it did on the PX77s, does the best job of attenuating glare from room lighting of any plasma we've tested yet. Check out the full review of the TH-50PX77U for details. In fact, the PZ77 plasmas seem like 1080p versions of the PX77 models in most respects, down to the lack of a PC input. We'll know more when we have a chance to review them.
CNET editors' buying advice
We have not reviewed this product but here is CNET's buying advice on Flat-panel TVs. This content was chosen based on the features included with this model of flat-panel tv.
Recommended Viewing Distances
Wide-screen televisions showing high-resolution content and HDTV look better than regular sets, allowing you to sit closer and experience a more immersive, theaterlike picture.
With wide-screen sets showing DVD, Blu-ray or HDTV, you can sit as close as 1.5 times the screen's diagonal measurement and still not notice much of a loss in quality, while sitting farther away than three times the screen size means you're likely to miss out on the immersive feel. Here's a rundown of minimum and maximum recommended viewing distances for wide-screen sets.

Size and your room
Generally, 32-inch and smaller sets are great for bedrooms or guest rooms but too small for the main living room. Sets with bigger screens are large enough for the whole family to enjoy and will probably be too much for most small bedrooms.
If you're mounting the set inside an entertainment center, be sure it fits in every dimension; also, leave an inch or two on all sides so that the TV has enough ventilation. If you're getting a bigger set, you may want to consider a dedicated stand; many TV makers sell matching stands that increase the aesthetic appeal of their hefty boxes.

Going "Green" with HDTV
In addition to considering screen size, TV type, and available features also consider ways to conserve energy. Below are a few energy consumption tips for your HDTV:
Turn the TV off when not in use.
Turn on the power-saver mode Many TVs these days come with a power-saver mode that's designed to cut down the power consumption. Performance of this mode varies from model to model, with the effect sometimes being drastic and other times providing only a slight savings. The only downside is that the power-saver mode usually makes the TV less bright, but we've found that sometimes this has a beneficial effect on the image quality, especially with the room lights turned off, in which case it's a win-win situation.
Turn down the LCD's backlight Many LCDs give you the ability to control the intensity of the backlight in the TV. By turning down the backlight, you'll lower power consumption, but also make the TV less bright. While retail stores love to turn the backlights up all the way for their displays, we find that we get the best image quality when we turn down the backlight significantly.
Control room lighting Reduction in the intensity of the backlight is going to make the TV less bright, but that can be compensated by controlling the light in your home theater room. While this may be a little overboard just for power consumption, limiting the light in your home theater also goes a long way toward creating the "theater" experience, as well as getting the most out of your TV.
And beyond TV concerns, good-quality blackout shades offer thermal benefits that keep other energy costs low; they keep heat in during the winter and keep it out during the summer.
Watch TV together Having multiple TVs in a house is more of a norm than a luxury these days, but that also means your power consumption is going to increase as well. You can cut that power consumption by watching with your family or housemates. You might need to make a few compromises on what you watch, but sometimes it's more fun to watch with friends and family.
Don't forget to properly recycle your old model If donating or repurposing your old TV is not a viable option, CNET encourages households to recycle their electronics. Please explore the following websites to find a recycling center in your area Electronics Take Back Coalition or Earth 911.
HDTV source resolutions
There are two main HD resolutions in use today by HD broadcasters and other sources: 1080i and 720p. One is not necessarily better than the other; 1080i has more lines and pixels, but 720p is a progressive-scan format that should deliver a smoother image that stays sharper during motion. Another format is also becoming better known: 1080p, which combines the superior resolution of 1080i with the progressive-scan smoothness of 720p. True 1080p content is extremely scarce, however, and none of the major networks have announced 1080p broadcasts. The term 1080p today appears mostly in reference to the displays' native resolution, not the source.
| Source resolution name | Resolution in pixels |
HDTV | Progressive scan | Widescreen | Networks/sources |
| 1080p | 1,920x1,080 | Yes | Yes | Yes | Blu-ray and future HD-DVD players; PlayStation 3 |
| 1080i | 1,920x1,080 | Yes | No | Yes | Includes CBS, NBC, PBS, DiscoveryHD/ Xbox 360 |
| 720p | 1,280x720 | Yes | Yes | Yes | ABC, Fox, ESPNHD |
| 480p | 852x480 | No | Yes | Yes | Fox wide-screen; progressive-scan DVD players |
| Regular TV | Up to 480 lines | No | No | No | All |
Despite the obvious difference in pixel count, 720p and 1080i both look great. In fact, unless you have a very large television and excellent source material, you'll have a hard time telling the difference between any of the HDTV resolutions. It's especially difficult to tell the difference between 1080i and 1080p sources. The difference between DVD and HDTV should be visible on most HDTVs, but especially on smaller sets, it's not nearly as drastic as the difference between standard TV and HDTV.

The truth about 1080p
In the last couple of years, there has been a big influx of HDTVs with 1080p native resolution, which typically cost a good deal more than their lower-resolution counterparts. But as we've been saying all along, once you get to high-def, the difference between resolutions becomes much more difficult to appreciate. We've done side-by-side tests between two 50-inch HDTVs, one with 1366x768 resolution (a.k.a. 720p) and the other with 1080p resolution, using the same 1080i and 1080p source material, and it was extremely difficult for us to see any difference. It becomes even more difficult at smaller screen sizes or farther seating distances--say, more than 1.5 times the diagonal measurement of the screen.
We're not telling you to ignore 1080p HDTVs. They technically do deliver more detail, which can enhance the viewing experience for more eagle-eyed viewers. Also, many manufacturers build other picture-quality benefits, such as better contrast and/or color, into their 1080p HDTVs simply because those sets are the high-end models. And given the continuing march of technology, we expect more and more 1080p models to become available at lower and lower prices. Today, however, the premium for 1080p is still pretty steep, and unless you're getting a very large set, say 55 inches or more, we don't recommend basing a buying decision on whether or not the television has 1080p native resolution.

Understanding HDMI
HDMI stands for High-Definition Multimedia Interface, and that's a pretty good description of what it is. In layman's terms, HDMI is a type of digital connection that's capable of transmitting high-definition video and high-resolution audio over a single cable. To do the same thing with analog cables, you'd need to connect three component-video cables plus six analog audio cables--that's a whole lot of cable clutter.
HDMI can deliver the best image quality of any of the cable types available today. It can handle high-definition video of up to 1080p resolution at 60 frames per second, which is the most bandwidth-intensive video format currently available. The older PC-based DVI connection offers equivalent quality, but it is rarely available on HDTVs or video components these days. Component video is found on nearly all electronics that output high-def video, and its image quality is slightly lower than HDMI, but it's really difficult for most people to tell the difference. Many viewers are probably familiar with the quality associated with the various standard-definition video cables--namely S-Video, composite (the yellow video cable), and RF--and HDMI provides a potentially huge improvement over all of them. As always, however, the biggest factor in video quality is the source; a low-quality source delivered over HDMI will still look worse than a high-quality source over S-Video.
For audio, HDMI is the reigning king of quality as well. It supports the ability to carry eight channels of 24-bit audio at 192kHz--enough to handle even the highest resolution audio soundtracks such as Dolby TrueHD and DTS-HD Master Audio. The only other connection type that can deliver the same quality are multichannel analog audio cables, but you'd need to run as many as eight separate cables to get the same quality. Digital audio cables--both optical and coaxial--can deliver multichannel audio, but are limited to lower-resolution audio signals.
