Performance

Activate the power saving mode : Many TVs these days come with a low power mode that is designed to reduce energy consumption. Performance of this mode varies from model to model, the effect sometimes being drastic and other times providing only weak economies. The only drawback is that the energy saving mode is usually the TV less bright, but we discovered that sometimes has a beneficial effect on image quality, especially with the room lights turned off, in this cases a win-win situation.
Turn down the LCD backlight : Many LCD will give you the ability to control the backlight on television. Reducing the backlight will be energy efficient, but also the television less bright. While retail stores love to turn the backlight all the way for their displays, we find that you get the best image quality when you lower the backlight significantly.
control room lighting Reduction intensity of the backlight will be on TV less bright, but it can be compensated by controlling the light in your home theater room. Although this is just a little at sea for energy consumption, limiting the light in your home theater also goes a long way toward creating the "theater" experience and make the most of your TV. And beyond TV concerns, good quality shades offer thermal performance that reduce energy costs low, keep warm in winter and summer off.

HDTV source resolutions

There are two main HD resolutions in use today by HD broadcasters and other sources: 1080i and 720p. It 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 picture 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 native resolution of the screen, not the source.

The truth about 1080p

Over the past two years, there has been a big influx of HDTVs with 1080p native resolution, which cost a good deal more than their counterparts in low resolution. But, as we have said all along, once you get to high definition, the difference between resolutions becomes much more difficult to assess. We've done side by side tests between two 50-inch HDTV, one with a resolution of 1366x768 (720p a.k.a) and the other with 1080p resolution, using the same 1080i and 1080p source material, and it was very difficult for us to see any difference. It becomes even more difficult to screen smaller or larger distances foundation - for example, more than 1.5 times the diagonal measurement of the screen.
We are not saying to ignore 1080p HDTVs. They are technically able to generate more details, which can improve the listening experience for most viewers in the eyes of an eagle. In addition, 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 technology in March, we expect models increasingly 1080p will be available at ever lower prices. Today, however, the premium for 1080p is still pretty steep, and unless you get a much larger set, say 55 inches or more, you should not base a purchase decision whether or not the television has a resolution 1080p native.

Understanding HDMI

HDMI stands for High Definition Multimedia Interface, and it is a fairly accurate description of what it is. In simpleman terms, HDMI is a digital connection that can transmit high-definition video and high-resolution audio over a single cable. To do the same thing with analog cables, you'll need to connect three component-video cables and six analog audio cables - that's a whole series of tangled cables. The HDMI can deliver the best image quality of any type of cable available today. It can handle high-definition video up to 1080p resolution at 60 frs, which is the video format more bandwidth available. The old PC 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 goods that output high-definition video, and image quality is slightly lower than HDMI, but it is really difficult for most people to understand 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 audio at 24-bit 192kHz - enough to handle even the highest resolution audio tracks like Dolby TrueHD and DTS-HD Master Audio. The type of connection to others who can provide the same quality are multichannel analog audio cable channels, but you must run up to eight separate cables to get the same quality. Digital audio cables - both optical and coaxial - can deliver multichannel audio, but simply a low-resolution audio.
