Best LCD TVs

Buying an LCD TV is more of an art than a purchase. Originally LCD TVs were available in only smaller sizes, but now they are available in sizes as big as 50 inches. Whether big or small screen, LCD TVs suffer from certain flaws: they have lower contrast ratios, slower refresh rates and narrow viewing angles. Despite that, if certain precautions are taken, you could end up with the best LCD TV in the market.

Currently Sony, LG, Samsung, Panasonic, Philips, Sharp are the bigger brands in the LCD TV market. Even computer monitor manufacturers like Dell and Gateway have made a foray into the LCD TV market. But a big brand name does not ensure that the TV is the best. Even reputed companies purchase monitors and other parts from other countries to save on costs. This affects the overall quality of the TV. It is essential to check out the TV while it is in the showroom before buying.

One thing to consider is the aspect ratio. Some widescreen LCD TVs boast of an aspect ratio of 16 to 9. However, believing blindly in this could be a mistake. Some screens just stretch the image to fit the screen. In doing so, the images become jagged and washed out. Best LCD TVs are those that can retain their resolutions even when the image is stretched to fit a 16 to 9 screen. Trust your eyes to judge that.

Another thing is the viewing angle. LCD TVs were big duds earlier regarding their viewing angles. Due to the pixel twisting principle of liquid crystal display monitors, LCD visuals would be almost invisible from more obtuse angles. But now, this problem is diminishing rapidly. Contemporary LCD TVs have viewing angles as obtuse as 160 degrees.

LCD TVs are available in three varieties: standard definition (SD), enhanced definition (ED) and high definition (HD). High definition TVs are the best as they can be used both as computer monitors as well as regular TVs as they can produce both digital as well as analog signals. These TVs have higher freeze rates and so they can better reproduce moving visuals. 

These are basically the important features to check while considering a good LCD TV. Best LCD TVs could be those that have all the above features along with sleekness in design, lightness of weight and easy button controls.

LCD Versus Plasma

A new television is high on everyone's wish list. Who wouldn't love a brand new fifty-inch flat screen TV hanging on their living room wall? The makers of televisions are taking advantage of ever-changing technology by creating scientific marvels that can produce clear pictures and lifelike colors in just a few inches of depth. But all of this technology means that buying a TV is harder than ever. These days, the battle between LCD and plasma is on, and choosing sides can be hard. Which one should you purchase?

Why buy a plasma TV?

Plasma TV's have a wide viewing angle. This means that the person sitting to the side of the television can enjoy the same picture quality as the person sitting in front of the television.  With an LCD, the picture quality diminishes if viewed from an angle. If you plan on mounting your TV high on a wall or above a fireplace, a plasma is your best bet, since the picture will remain clear when viewed from the ground. Plasma TV's are known for having high contrast and deep black levels. This is most evident in nighttime scenes in movies and shows; the colors appear lifelike and every detail shows, even in dark scenes. Plasma TV's are also less expensive than LCD's. When the price per inch is compared, plasma TV's are a budget's best friend.

Why buy an LCD?

If you are looking to reduce your monthly electricity bills, you will want to purchase an LCD TV. The savings are minimal - often just a few dollars a month - but will add up over the lifetime of the television. And since an LCD TV uses less electricity, it is the greener option. You might also want to purchase an LCD if someone in your family is an avid video gamer. Video games often feature static images, like the score box or the countdown timer, that do not move. With a plasma TV, these static images can burn into the screen; this burn-in is not a problem with an LCD. You also need to consider the level of light in the room. LCD's are well suited to bright rooms. The screen is less reflective than a plasma, and as such will not show the reflections of windows or lights. Also, LCD's have a brighter picture; under the harsh glow of daylight or lamplight, viewers will still see a clear and bright picture on the screen.

In a battle between plasma and LCD, there is no clear winner. You should buy whichever television best suits your needs. But before purchasing a TV, you need to remember some key rules. First, match the size of the television to the size of the room; contrary to popular belief, the television should not be larger than the room itself. Second, shop around. Prices for both plasma and LCD TV's are coming down by the day, so you might find a bargain if you do a little comparison shopping.  And third, if you are technically challenged, hire someone to install the electrical components for you. This way, you can sit back and enjoy your favorite show with all of your fingers intact.

Hitachi plasma flat TV

This flat screen television, the Hitachi Plasma Half Life 55-HDM71, performs sharply and smoothly. With its high resolution of 1366 x 768, this plasma flat TV can't be beat. There is 20% more picture on this 55" screen than there is on a standard 50" screen. The 10 bit image processing on Hitachi Plasma Half Life 55-HDM71 brings a vibrant picture with 1.07-billion color capability and great contrast, which makes it perform like a smaller television.

Aside from the screen capabilities, this Hitachi plasma flat TV also includes extension modes, full serial control, and a 20-watt audio amplifier. On top of this, there is picture-in-picture and split-screen image control for home theater and commercial use. Additionally, there is the option of including a swivel table top stand, wall mount bracket, and black or silver side mount speakers. Along with the Hitachi plasma monitors' normal technology and seamless integration, it makes for a great flat tv.

The single drawback to the Hitachi Plasma Half Life 55-HDM71 is that it ships with "black enhancement on." This means when you are watching the TV, there will be no detail in the dark scenes, but it is resolved easily enough. If you turn off the back enhance, and change the colors settings a bit, it will solve the problem. There are several things that can be done to extend the life of the display. Along with screen savers that employ orbiting, inverting and wiping to refresh the screen, there are also many other options to maximize the life on this plasma TV.

Plasma Tv

Plasma TVs have become increasingly available, and their cost is lowering all the time. We have all heard about plasma TVs, and advertising campaigns are constantly telling us that they are the status symbol to have. Adverts are extremely effective at glorifying the benefits of having a plasma TV, so much so that it appears that even our pulling power and popularity will be improved. The one thing that these adverts don’t really tell us is what a plasma TV actually is. Here is a brief guide to plasma TVs to help you appreciate this apparent miracle of modern technology.

Plasma TVs have a higher resolution than other conventional display devices which means that they can display the high definition signals of HDTV and DTV. Also, plasma TVs are compatible with the computer signals SVGA, VGA, and XGA.

Unlike other display devices, plasma TVs have a transistor electrode for every pixel cell which means that there are none of the scan lines that are visible with regular TV sets. The whole image is evenly lit across the display by these electrodes, and not produced by an electron beam which is the cause of scan lines.

Top-of-the-range plasma TVs have display capabilities of over 16 million colours. This ensures that the picture has far more realistic colour than that shown on a conventional TV screen. This is because they are able to show far more shades of colours compared to the lesser quality TV screens.

Plasma TV screens are completely flat which has two benefits. There is no edge distortion, unlike on more curved conventional TV screens, and also there is a far wider viewing angle. The viewing angle of a plasma TV is 160 degrees, and allows the image to be seen properly from more areas of the room where the TV set is situated. This makes plasma TV screens ideal for large groups to view, and lessens the need for more than one TV set to be placed.

Of course, the main benefit that most people are aware of with plasma TVs is their space-saving quality. They are extremely shallow, and can therefore be installed in many more locations than a conventional TV set. The depth of a 50 inch screen is approximately 4 inches, and it can therefore be hung on a wall.
