Plasma Tv Care 101

Writen by Christine Peppler

Many thousands of people purchase their first plasma screen TV each year. They invest a significant amount of money to obtain a plasma screen which offers top of the line color accuracy, vibrancy, and clarity to enhance their family's viewing experience. Once the television is delivered however, it's important for plasma buyers to take the time to become familiar with the proper care of the screen to assure many years of trouble free viewing enjoyment. Plasma screens aren't really "high maintenance" but observing a few tips offered here can extend the life of the screen.

• Provide a solid foundation: Be sure the plasma screen is placed (or mounted) in an area where it will not be "knocked around" or will accidentally fall.

• Let it breathe: Plasma screens generate a lot of heat which can speed the demise of the electrical components of the unit. Be sure the TV has enough open space around it. The manufacturer will provide venting guidelines.

• Stay dry: Exposure to excessive humidity, spills, or condensation due to rapid changes in temperature can destroy electrical components and cause corrosion.

• Tone it down: Rooms with lower ambient light require less brightness. Brightness levels that are set too high will prematurely age the phosphor lining of the plasma screen.

• Keep it cool: As alluded to above, plasma screens require a cool environment, due primarily to the heat they generate. Outdoor placement of a plasma screen is a no-no due to the exposure to heat, humidity, other moisture, and dirt.

• Use a little "elbow grease"- but not too much: Keep the screen clean with the proper tools. Manufacturers seldom recommend strong cleaners. Most often a micro fiber cloth is recommended which is effective in ridding the screen of dust and finger prints. When more aggressive cleaning is necessary cleaners specifically made for plasma or PC screens (anti-static cleaners) are used but should never be sprayed directly on the screen. The cleaner should be applied to the cloth. Use of paper towels, Kleenex, or any other abrasive type cloths should be avoided as they can damage the anti-glare coating.

• Don't get burnt: Although anti-burn in technology has advanced greatly over the years, it is best to avoid leaving static images on the screen. This means that images should not be paused on the screen for extended periods of time and stations which present a static block/image on the screen should be viewed on a limited basis as well. Hooking your PC up to a plasma screen is also inadvisable as they are often used to display static images.

• Help your plasma TV weather the storm: This is just common sense; use a surge protector.

• Prevent pre-mature aging: The final word of caution; turn plasma screens off when not in use. This can help avoid accidental burn in, reduce heat, and help to avoid decreased brightness/pre-mature aging.

Hdtv Buying Guide Part Two

Writen by James Ambras

In my last article I wrote how there's never been a better time to buy a high definition (HD) television, and I had just preordered the Samsung HLS-5087W 50 inch rear projection DLP unit. The Samsung was delivered last Thursday and here's a summary of my initial reaction.

First let me give some background on preparing for the new HD television. I'm a satellite TV subscriber and needed to upgrade my DirecTV hardware to be HD-compatible. So last month I logged on to www.directv.com and ordered the HD upgrade package. For $200 DirecTV came out and replaced my old satellite dish with a new 5-LNB oval HD dish. The HD package included the lease of DirecTV's new H20 HD receiver, and also included installing a new UHF antenna on my roof to receive other-the-air (OTA) HD local broadcasts. The new dish and receiver were required for HD reception since DirecTV is transmitting local HD broadcasts in the new MPEG-4 compression format instead of the older MPEG-2 standard. Since HD material requires much more bandwidth than standard definition video, satellite and cable providers will be migrating to the new MPEG-4 standard over time and DirecTV is leading the way for now.

I was now all set to receive HD programming as soon as Samsung HLS-5087W arrived with one exception - an HDMI cable to output the digital video/audio signal from the H20 to the Samsung. I'm a big believer in investing in high quality cables for analog connections between audio/video components. But HDMI is a digital interface that transmits a stream of 0's and 1's. So either it works or it doesn't. I therefore bought a $20 HDMI cable on the Web instead of investing $90 or more for a Monster cable that I thought would yield exactly the same audio and video quality. One great thing about HDMI is that it carries both video and audio signals (in uncompressed, digital form) so you can easily reduce the cable clutter behind your home theater system.

Now everything was all set - I just needed the new Samsung to be delivered. I ordered the television from Crutchfield, which has a great reputation for customer service, is an authorized Samsung online retailer, and offered the television with no tax or shipping charges. The delivery guys brought the television into my living room, took it out of the box and placed it on my home theater stand. I connected the power cable, connected the HDMI cable form the H20 to the Samsung, turned on the power, modified the TV display type on the H20 from 4:3 to 16:9 and amazingly the new television just worked, right out of the box!

I was quickly in HD nirvana - watching local broadcasts in full 1080i and Dolby Digital 5.1, as well as premium services such as HBOHD and the various HD channels that are part of DirecTV's HD package. But how would the 150 DVDs I own (most of which I trade via Peerflix) look on the new HD Samsung? I first had to bring up the menu on my Panasonic DVD recorder/player and activate 480p output over the component cables that I connected to the Samsung. Most DVD players sold in the last three years can output a progressive signal (the "p" in 480p) over component cables instead of the normal interlaced picture transmitted on composite and S-video connections. 480p is a big visible improvement over 480i and you'll want to make sure you are watching all of you DVDs on a HD television using 480p.

I chose Shrek as the first DVD to showcase on the Samsung. Dreamworks did an amazing job with the animation quality of Shrek and thought the DVD would be a good test of the picture quality of a standard definition DVD on a HD television. So how did it look? One word sums it up - amazing! I don't expect I'll be going out to the movies much any more - I'll just wait for the DVD to come out.

On Saturday night I watched a broadcast of Steve Winwood in HD and Dolby Digital 5.1 on KQED, the local PBS affiliate. Being a huge Steve Winwood fan, and having seen Winwood on this tour at a local venue in 2005, I was eager to see what kind of audio/video experience the new HD unit could deliver via a local, OTA HD broadcast. Once again, I was just stunned by the picture quality and quickly went to KQED's web site to see what future Soundstage broadcasts are scheduled. I'm now eagerly awaiting Garbage's performance premiering next month.

There was one more thing left to do though before I could experience the maximum picture quality from the new Samsung - I needed to calibrate the picture for maximum video quality. Virtually all televisions sold today ship from the factory with video settings that are far from optimal. Colors are typically oversaturated, with too warm a tone, and sharpness, brightness and contrast controls that are far from optimal as well. So I dug out my copy of "Video Essentials: Optimizing Your Audio/Video System" DVD and spent a half hour adjusting the color, brightness, contrast and sharpness controls. The HLS-5087W has numeric display of each of these settings, which is a nice touch for those of us who go through the trouble of tweaking every setting possible for maximum picture quality. It was hard to believe that I could improve upon the quality of the Samsung's picture out of the box, but fine-tuning the picture settings resulted in a much more "film-like" appearance of movies from both my DVD player and H20 receiver.

I'm looking forward to watching the season premiere of HBO's Entourage series in full HD glory tonight. It's also going to be difficult holding off purchasing a HD DVD source with HD-DVD and Blu-ray players and titles now starting to appear. But we'll talk about that in our next posting on Tech Talk.

A Buyers Guide To Lcd Tvs

Writen by John Dulaney

As one would expect, the prices of LCD televisions will vary quite a bit depending on the size of the display, the quality of the display, the resolution of the screen, the brand name of the television and a number of other factors. The prices of LCD TVs has come down quite a bit, and the smaller models are generally available for a couple hundred dollars at many discount retailers and electronics stores.

When it comes to the high end of the market, however, the sky is still the limit, and it is possible to purchase a room filling LCD or plasma display that can run to $10,000 or even more.

Most LCD TV shoppers, of course, will fall somewhere in the middle, and most consumer sized TVs, those in the 23" to 40" inch range, will have retail prices set from just under $1,000 to just under $3,000. The world of LCD technology is populated by the biggest names in the world of electronics manufacturers, including such names as Samsung, Sony, Sharp, Phillips, Panasonic and Toshiba. Computer maker Dell also makes a line of LCD television displays that have been generating a great deal of excitement with all kinds of technology buffs.

While the prices of these LCD televisions are still quite a bit higher than traditional CRT (cathode ray tube) models, consumers do get a number of important advantages for this extra outlay of cash. Some of the most significant benefits of the new LCD TV technology include:

Perfectly Flat Screens

The curvature built into the display of a traditional CRT television can introduce edge distortion and shadows on the screen. The true flat nature of the LCD screen eliminates this edge distortion and provides a steady and more reliable display.

True Widescreen Performance

Unlike traditional televisions, the LCD television display uses a widescreen aspect ratio of 16:9. This aspect ratio is the relationship of the width and height of the screen, and the LCD display will appear much longer than it is high. The 16:9 aspect ratio is used to send HDTV signals, and it is also used in the production of widescreen DVDs and VHS videos. The LCD aspect ratio allows owners of these TVs to watch movies as they were intended to be seen in the theater.

Superior Viewing Angle

Compared to rear projection TVs, LCD television displays provide a 160 degree viewing angle, and they can be viewed at virtually any angle, horizontally or vertically.

Exceptional Color Accuracy

The best LCD displays are capable of producing more than 16 million unique colors, and this incredible depth of color provides for exceptional color quality and superior color accuracy.

Flexibility and Versatility

Many LCD televisions are designed to accept input from a variety of different devices, including computers, DVD players, VCRs, Laser Disc players and of course satellite and cable TV systems. In addition, multisystem LCD displays are designed to work with a variety of different television signals, including PAL, NTSC and SECAM. This allows the same television to be used in a variety of different countries, as the television broadcast standards vary from location to location.

Better Expected Reliability

Tests of LCD and plasma TVs have found that the average life expectancy for such devices are approximately 35,000 hours. That means that if the display was used for four hours a day it should last about 20 years.

In order to better understand these important advantages it is a good idea to understand just how this technology works. The LCD display is made up of a large number of picture elements, known in the industry as pixels. The number of pixels is one of the elements that will determine the overall quality of the picture. The number of pixels used in an LCD display will vary from hundreds of thousands to many millions, and the higher the number of pixels the better and sharper the display of the unit should be.

The aspect ratio of the LCD display is also different from that of the traditional CRT television. While the traditional CRT display uses a 4:3 aspect ratio, the LCD display uses a 16:9 aspect ratio. Simply put the aspect ratio is the relationship between the length and height of the TV, and the 16:9 aspect ratio is used to broadcast HDTV signals, as well as being used by manufacturers of widescreen DVDs and VHS tapes. This widescreen aspect ratio allows watchers of LCD displays to experience movies in true movie theatre format.

There are a number of considerations when looking shopping for an LCD display, including the tuner used by the set. The LCD TV should be able to accept inputs from a variety of different tuning sources, including satellite TV boxes, cable TV boxes, DVD players, VCRs and the like. For those living around the world, it is also important to make sure that the LCD TV you choose be capable of accepting not only NTSC video signals, which are the standard in North America and Japan, but also the PAL and SECAM standards used around the world.

Of course it is important to shop for the highest quality LCD TV you can afford, just as it is important to shop for the best price on the highest quality TVs. It is often possible to shave hundreds of dollars off of the retail price of an LCD display simply by shopping around at a wide variety of retailers, both on and off the internet.

In addition, it is important that the accessories and cables you purchase are of the highest quality. The right cables will enhance the value and versatility of the television itself, and it is important to spend a little more and get the highest quality cables to connect your DVD player, VCR, game console, computer or other device to that great looking LCD display.

110-220 Volt Electronics - A multisystem TV is a TV capable of receiving and displaying different video systems like PAL, SECAM and NTSC. You'll be able to operate a multisystem TV in 99% of the world. Their dual voltage design allows them to be plugged into either a 110 voltage source or a 220 voltage source. In some cases, the plug on the television will not fit your country's outlet, so an inexpensive plug-adapter will be needed. They can generally be picked up at an electronics store such as http://www.planetomni.com for $1.95. With a multisystem TV, such as a plasma, CRT tube type, LCD or DLP, you'll likely need a codefree (sometimes called region free) DVD player. These exist in many forms. When used with a PAL-NTSC TV you'll be able to see the full 625 lines of resolution available in the PAL system and the full 525 lines used in the USA NTSC system. There exists a converting type of DVD player which is codefree in that it can read all of the world's 6 regions and both standards, PAL and NTSC. 140,000 other products are available here: http://www.planetomni.com Tel. # 800-514-2984
