The bigger the screen the more impressive is the public, for this reason, advertising big screen little by little in a sector of the economy all over him to grow his own.

We were out of home digital signage for a number of years and has participated during the past quarter, we experienced a massive increase in demand for big-screen television to cover the attention of potential customers and marketing to them.

Now the problem is with a large screen TV, is that the TVs arelikely to be expensive, for example Mitsubishi offers a 65" display for $6,000 this is no means the most expensive display available, so when you deploy a screen of this value you have to look at protecting it from theft, vandalism and of course the weather.

This big screen TV cabinet are normally supplied with an internal mounting frame for the TV that has special security fasteners preventing anyone without the special tool removing it. Some outdoor TV cabinets have been supplied with webcams that record anyone who comes close to the display, this way should anything un-towards happen to the display there is a record and am image that can be used in court to prosecute the individual responsible.

Another issue is the mounting of the big screen, as you need a structure that is strong enough to support it once fastened into position. You have to decide if you wish to mount the TV direct to the wall, or from the ceiling or floor. However which ever you choose, you have to ensure that the mounting frame can support both the TV and the big screen TV cabinet with a total weight of around 200lbs.

LCD stands for Liquid Crystal Display, and at the same time, technology has been around for 3 decades, is only now that LCD monitors and TV are always the person per day is the average life.

The clear advantages of using an LCD display on older CRT monitors is the size difference. LCDs are a fraction of the depth that gives you more space. This also applies to TVs. large screens still oneMinimum depth, then, do not take your living area.

Outside of losing some of the spots.

Resolution

Some cheaper models or more screens, problems with unsupported resolutions.This is not usually a problem, but one worth considering, depending on the intended use. N-running in a resolution supported may lead to blurred images.

Do not give up on tubes ... with flat screen TVs, like plasma and LCD emerging today, most consumers are aware of very wrong and I believe that the quality of a dish better than a tube (CRT) TV. This is not true. The image quality of a plasma or LCD far less than a CRT, such as the Sony KD-34XBR970. Worse, more and more people buy this flat screen TV as a status symbol and do not understand the true quality. Why do you think studiosCRT use in the production and use of transformation rather than a plasma TV? Most studios want to better this as closely as possible so that they are using CRT monitors. The quality of the Sony KD-34XBR970 is much like a studio monitor, and exceeds all other displays, regardless of cost. The dot pitch is so fine and the picture is so realistic to the point where all the other displays look dirty and dull in comparison. The convergence and perfect geometry is out of the box, and the crowd lookedfantastic. Her image was depth and dimension, in contrast with the flat look of most plasma and LCD. HD channels look incredible, they are very real and not increased excessively. processing on board the Sony and the Democratic Republic of Congo is perfect and does not look all pixilated sources. The image is good, clear and has an extraordinary level of detail.

One limitation to note: The set comes in "Vivid, which means grab your attention in business with a bright picture, but inaccurate. Itis too bright and too sharp. You can see the outlines of images and artifacts in this mode. If you keep the TV in Vivid mode, you are guaranteed to burn the tubes in no time and shorten the life of the TV. The vividly is very accurate in color reproduction. I calibrated my set in "Movie, with a picture (white level) setting of 20/63 and a brightness (black level) setting of 30/63. Remember, it is very important for the 'image' approach, because lower controlsAmount of white light on the screen. If you do this, the tube will last a long time, and you will see an unusual picture. On the other hand, the "brightness" setting controls the amount of dark areas you see in the picture. If this device allows you to see the darker areas in a film, but not burn the tubes or impair the image quality. A clear picture is better than a light.

Finally, the color decoder adjustment as strongly emphasizes and makes redPeople are looking reddish or brown. If the 'axis of color "setting" default "to" monitor ", the colors are more accurate and vivid. If you set this set is correct and is in good hands, they produce the best TV film at a time and will take very long time. (My old XBR TV is 16 years old and over.) I have a neighbor, the $ 10,000 on a plasma TV and the output image quality is much worse in this series. What type of television you buy? status symbol is moremore important than image quality? Remember that after reading this review, are a much more educated consumer.

How to Clean Your LCD TV screen


Image : http://www.flickr.com


* Easily Scratched!

First we have to understand a little bit of background about LCD screens to know why we should be careful when cleaning. LCD stands for Liquid Crystal Display; which has crystal molecules sandwiched under layers of polarized panels. These panels are usually made of "plastic-like" polymer materials, and like any plastics they can be easily scratched or gouged, even by just your fingernails! That's why cleaning LCDs requires special care while cleaning compared to the old glass CRT monitors!

* What You'll Need

- rubbing alcohol (aka isopropyl alcohol)

- distilled water (not tap water!)

- A soft cloth (lint-free)

* Steps

1. Dilute the rubbing alcohol into a mix with about 50% alcohol and the rest distilled water.

2. Pour this solution into a spray bottle. Old Windex bottles are good as they spray in a mist pattern with just the right amount to get good coverage on your screen. The spray bottles that squirt a single stream tend to drip solution all over the place.

3. Spray the mix onto a soft lint-free cloth. Old t-shirts and microfiber car wash cloths are both good choices. Large cloths are better since it helps to reduce the risk of leaving streaks on the screen from too much pressure.

4. Gently wipe the cloth on the screen in a circular consistent motion. Apply even pressure to the cloth and be careful not to push too hard, or scrape the screen with your fingernails!

* Suggestions

- Costly products that you buy at the "computer screen cleaning" aisle of your local computer store contain the same basic ingredients of alcohol and water! Some even contain other harmful chemicals such as ethylene glycol, which may be ok on older glass CRT monitors, but should NOT be used on LCD screens! Some of the extra chemicals can also be harmful to the environment and to your health.

- Be sure to use Mineral water! Not tap water; you don't want hard mineral spots on your screen.

- Don't use tissue paper; they will leave lint and spots of paper stuck to your monitor. Also they're too thin, risking damage from your fingernails poking through.

- Don't apply too much solution. If you do, just wipe it off with the cloth and use less.

- You can also use lint-free lens wipes from photography stores, but they're thinner so be careful about your fingernails poking through.

- For a cheap ready-made solution from the store, you can also use CD/DVD cleaner, It's already designed to be plastic-safe, and is a simple solution of about 50% isopropyl alcohol.

* Some Precautions

- Don't use Windex or other glass cleaners! These contain ammonia, which is ok for glass, but WILL hurt your LCD screen!

- Try not to use the really cheap paper towels, like the tough brown ones in public washrooms. They can scratch your screen.

- Be sure to shut down your computer and your monitor, then unplug from the wall. This reduces the risk of electric damage in case you spill some of the solution on components.

- Don't drink isopropyl alcohol! It's toxic!

- If you aren't sure, you can test a small corner of the screen first.

Follow the steps and suggestions above, and your trusty LCD monitor should give you years of clean, clear, trouble-free service.

LCD TV Comparison - How to Find the Best LCD TV?

If you're looking for an LCD TV comparison, you're probably already in love with the idea of hanging a flat screen TV on your wall. It's really amazing how technology has progressed to the point where you can hang a big screen TV on your wall, then sit back and enjoy a fantastic HDTV picture of your favorite TV shows or sporting events.

Even more amazing is that as pictures have improved by leaps and bounds, the TVs have gotten thinner, and prices have plummeted. You know that any TV you choose is bound to net you a superb picture and slim form factor.

That being said, you know all the LCD TVs out there can't be the same, can they? Surely there must be some differences, right? Well, yes there are. There are a few things that some TVs do better than others and when making an LCD TV comparison, you should know how to find the differences. Although LCD TV prices have declined substantially in recent years, you want to be sure you're getting the most TV for your money, and the best one for your particular application.

One of the first things to think about is the physical size of the set. If it wasn't so common it would be funny, but people will often make or buy a cabinet, then try to find a TV to fit in the space allocated. Many times they're thwarted form going up to the next larger sized TV because one of the cabinet dimensions is an inch or so too small.

Take the time to choose your TV first, if you have the opportunity. This will also prevent you from designing or buying a cabinet for a particular TV, only to find it's been discontinued when it comes time to buy the TV.

The next thing is to look at some of the new LCD TVs with thin bezels. For example, this can allow you to fit a 40" TV where only a 37" set would fit before. Something to be aware of is that sometimes these extra thin bezel LCD TVs are deeper than their normal beveled cousins. If you're putting your new TV in a cabinet, this may not be a concern to you, but the extra 2" - 3" may make a big difference if you're hanging the set on a wall.

If the TV will fit where you'd like to put it, a check on picture quality is in order. After all your buying a new TV to watch it, and there are some ways you can compare the picture quality to determine which set has a better picture.

One problem with just looking at a set on the showroom floor is that rarely are all the TVs correctly adjusted for the best picture. Often they're shipped and set up in what the industry terms "torch mode". This is slang for having the settings adjusted to take advantage of most customer's preference for the brightest TV they see. If there are 10 TVs lined up, they'll gravitate toward the brightest one. In many cases the brightest TV is not the one with the best picture, especially if it has been adjusted to look artificially bright.

Most LCD TVs, especially 1080p sets, have more than enough brightness for any viewing situation, save putting the set in direct sunlight, but no brightness or contrast adjustment will save you there. The point is that looking at a TV in the showroom will often not provide you with an accurate representation of the set's available picture quality.

When shopping for an LCD TV, a 120Hz refresh rate is one feature that has gone a long way toward eliminating the motion artifact problems that used to be so prevalent in LCD televisions. It is common on most manufacturer's better LCD sets now and is known by many trade names.

Sharp has no trade name for their sets with the 120Hz feature, calling it just "120Hz frame rate conversion", Toshiba uses the moniker "ClearFrame(TM)", Mitsubishi prefers "Smooth 120Hz(TM)", and Sony's marketing department came up with "Motionflow(TM) 120Hz". It all means basically the same thing. Your LCD with this technology will look much better on fast moving images, like sports and scrolling text, than TVs without it.

If you're looking at one of the newest TVs, make sure they have plenty of inputs for connecting your BluRay player, cable box or satellite receiver, computer, or digital camcorder. In many instances, you will connect everything up to your surround sound receiver, then run a single cable to your TV.

For those not using a surround receiver, having plenty of inputs becomes vitally important. Make sure you have art least 3 HDMI inputs so you can get the best possible picture from HD digital video sources. A couple of component video inputs for older sources such as DVD players is a good idea as well.

Most new TVs have a digital tuner built in so you can connect an HDTV antenna and pick up signals broadcast over the air. Some TVs have what's called a QUAM tuner. This will allow you to get unencrypted digital cable programming. In many cases the cable company will broadcast local channels in full HDTV resolution "in the clear". That means they are not encrypted and you can watch them with no cable box, just the QUAM tuner built into your TV.

This will give some things to look for when comparing new LCD TVs. Whatever TV you decide to buy, you will get many years of enjoyment from your new set.

What is the Best Flat Screen LCD HD TV to Purchase For the Money?

Don't give up on tubes...With flat panel TVs emerging nowadays such as plasmas and LCDs, most consumers are highly misinformed and believe that the quality of a flat panel is better than that of a tube (CRT) TV. This is not true at all. The image quality of a plasma or LCD TVs far inferior to a CRT, such as the Sony KD-34XBR970. Even worse, more and more people are buying these flat panel TVs as a 'status symbol' and do not understand true picture quality. Why do you think studios use CRT monitors during production and editing instead of a plasma TV? Most studios want the best, most accurate picture possible, so they use CRT monitors. The quality of the Sony KD-34XBR970 is much like a studio monitor, and surpasses all other displays regardless of cost. The dot pitch is so fine and the picture has so much realism to the point where all other displays look dull and muddy in comparison. Convergence and geometry is perfect out of the box, and the set looked fantastic. Its picture had depth and dimension, unlike the flat look of most plasma and LCD TVs. HD channels look amazing they are very real and are not overly enhanced. The Sony's on-board processing and DRC is perfect and does not make sources look pixelated at all. The picture is fine, clear, and has exceptional detail.

One caveat to remember: The set is shipped in 'Vivid' mode, which is meant to grab your attention in the stores with a bright picture but lacking in clarity. It is way too bright and much too sharp. You can see outlines and picture artifacts in this mode. If you keep the TV in Vivid mode, you are guaranteed to burn the tubes in no time and shorten the life of the TV. Also, the vivid mode is very inaccurate in color reproduction. I have my set calibrated in the 'Movie' mode, with a picture (white level) setting of 20/63 and a brightness (black level) setting of 30/63. Remember, it is very important to lower the 'picture' setting because it controls the amount of white light on the screen. If you do this, the tube will last a very long time and you will see an exceptional image. On the other hand, the 'brightness' setting controls the amount of dark areas you see in the picture. Turning this setting up will allow you to see more dark areas in a movie, but will not burn the tubes or impair image quality. An accurate image is better than a bright one.

Finally, the color decoder needs adjustment as it emphasizes red severely and makes people look reddish or tanned. If you change the 'color axis' setting from 'Default' to 'Monitor,' the colors will be much more accurate and vibrant. If you adjust this set properly and take good care of it, it will produce the best picture of any TV and will last a very long time. (My old XBR TV is 16 years old and still going.) I have a neighbor who spent $10,000 on a plasma TV and the picture quality is far worse than this set. What kind of TV would you buy? Is status symbol more important than image quality? Remember, that after reading this review, you are a much more educated consumer.
