Panasonic TC-P50G25

We haven't had a chance to fully test this product yet, but we've assembled this helpful overview of relevant information on it.

The Panasonic TC-P50G25 is a part of Panasonic’s 2009 Viera G25  series of plasma televisions. This 50-inch TV comes with a Infinite Black contrast ratio of 5,000,000:1 which is more than most TVs which come in at 2,000,000:1. This set offers a THX-certified Display giving viewers cinema-level quality images and features a 600Hz Sub-field drive for clarity of motion. The broadcast display is in 1080p HD and comes with three HDMI ports. Two 20 watt speakers are built-in to the system allowing for greater sound. Most plasma TVs only have 10 watt speakers built-in. The G25 series is Energy Star Compliant. You can view Netflix, stream Youtube and use your Twitter and Skype accounts through Viera Cast. This model is webcam capable and features two USB ports as well as a PC connector for those who want to use the set as a monitor or connect peripherals to it. The G25 series is Energy Star Compliant.

Do I need an ATSC tuner?

If you plan on watching, free, over-the-air programming, then yes. As of 2009, all over-the-air broadcasts use the ATSC standard. Pretty much all HDTVs manufactured over the past few years will include this feature.

What are widgets?

Many of the top television manufacturers – including Sony, Sharp, Panasonic and Samsung – include Ethernet jacks on the back of their premium televisions for high-speed Internet connectivity (or in some cases, have integrated Wi-Fi for wireless connections). TV viewers will then use the remote to select “widgets,” graphicalicons on the screen that plays relevant (and customized) content ranging from YouTube videos and Flickr photo galleries to local weather, news, sports updates and stock quotes, usually delivered by Really Simple Syndication (RSS). Even more exciting is the partnership between Netflix and various TV companies, such as LG and Sony, allowingtelevision viewers to access tens of thousands of movies on-demand, many of which are in high-definition.

What resolution do I need?

All consumer HDTVs break down into either 720p or 1080p resolution, which represents the number of horizontal lines in the display. More is obviously better here, but at small screen sizes – like 32 inches – many people find it hard to distinguish the benefit of 1080p resolution. As our guide to screen size points out, viewing distance can also play a factor: The closer you sit, the more you’ll appreciate higher resolution. In general, many people start to see an obvious difference between 1080p and 720p as screens sized 40 inches and up.

Also take into account that much of the content available today doesn’t take advantage of full 1080p resolution. Many shows still broadcast in 720p or 1080i. Technically only Blu-ray discs and digital, non-video sources (like a PlayStation 3, Xbox 360, or PC hooked up to the TV), really offer true 1080p content. This makes 1080p a no-brainer if you want to play Mass Effect 2 with the most detail and watch Star Trek on Blu-ray, but less essential if you just play to watch standard over-the-air broadcast material.

What is a LED backlighting?

Traditionally, LCD TVs have used compact fluorescent (CFL) tubes placed behind an LCD panel to provide the backlighting that literally lights up the screen. More modern LED TVs replace these tubes with clusters of light emitting diodes – LEDs.

When LEDs are placed at the edges of the screen, as CFL tubes traditionally were, TVs can be made significantly thinner, and LEDs use less power than fluorescents. The most inexpensive LED-lit HDTVs take this approach.

However, the biggest advantage to using LEDs is realized when they light the screen in a grid from behind. Sophisticated electronics vary the intensity of every LED in accordance with action on the screen, making dark areas of the image darker, and bright areas brighter. This effectively increases the contrast ratio compared to uniform lighting. Although it also increases costs, many people believe this type of LCD is the first to truly rival plasma on black levels.
