High definition tv Contrast Ratio Described - How to pick the very best Lcd Television - Dynamic Contrast Ratio

Introduction to Contrast Ratio: Contrast ratio (CR) is a parameter stated for all HDTVs, but is often very misunderstood. Before the flat panel revolution, CRT televisions never advertised this figure. The answer is simple and lies in the technology. CRTs use an electron beam to illuminate phosphors on the screen and create a picture. If the electron beam is switched off, that section of the screen turns absolutely black. White areas would max out the electron beam. Theoretically, old school TVs had an infinite CR, and blacks were displayed to perfection.

LCD HDTV Contrast Ratio: Modern LCD TVs use twisted nematic crystals to create the picture. What does that mean? Quite simply it is the same as using horizontal window blinds to allow or block light. Each tiny cell on your monitor has sub cells with red, green and blue polarizers. Each cell is controlled by a transistor (TFT is Thin Film Transistor) and thus the perceived intensity of the bright backlight can be controlled. To create black, the cell is ordered completely shut. The problem is (as with the horizontal blinds) that some light will always bleed through the crystals. This undesirable effect produces blacks that are somewhat gray and even colors that don't seem to pop. Inexpensive, bargain brand LCDs may suffer from this problem. Most people however do not notice this issue until it is pointed out to them.

CR Measurement: LCD makers are free to measure CR in any way that they please. There is no current standard and it is incorrect to compare contrast ratio between manufactures. Basically CR is measured by taking a light intensity reading of the brightest area vs the darkest area on the screen. If the brightest area of the screen is 2500, and the darkest area 10, you have a 250:1 CR. Of course, how you set brightness, contrast, etc. on the TV can have a big impact on these measurements. Also, equipment calibration and setup can have a bearing. Finally, your eyes will perceive contrast differently based on ambient light settings. Do you ever wonder why movies turn down the lights? That should give you a big clue. Also, do not buy a glossy screen if there is ambient light in the room. If you are going to be watching TV in a room with windows and sunlight, opt for a matte screen.

Dynamic CR: Despite the large contrast ratio numbers advertised, bare panels may have CR figures in the 1000:1 range. However, by manipulating back light intensity based on actual scenery, TV makers can get six and seven figure contrast ratio measurements. For example, why run the back light on full intensity when you are looking at the night sky with stars? Dim the bulb, and less light will bleed through the black area giving the illusion of a much higher contrast ratio. Almost all LCD TVs sold now have dynamic contrast ratio. When you purchase a TV, look for contrast ratios above 40000:1 and a dynamic CR number. One last word, dynamic contrast ration isn't a perfect solution, sometimes you have a very dark scene with a small portion of the screen very bright (like a moon lit night). A scene like that could make the difference between a great TV and a mediocre one.

LED Lighting: A new advance in technology uses clusters of LEDs to illuminate the screen instead of a single lamp running the top length of the TV. The Samsung UN55C7000 is an example of such a TV. These TVs can create total blackness in certain areas of the screen, theoretically creating a near infinite (or seven figure) contrast ratio. Because the CR is so high, these TVs can create life like 3D images that appear to lift off the screen!

What should you consider when buying an HDTV? Do not make contrast ratio a major purchasing point. As a rule, look at contrast ratios in factors of ten. A TV with a 600K:1 CR is probably better than one with a 60K:1. Do not simply choose a TV because the CR is a few thousand higher. Read Reviews and pay attention to tag words like black and shadow detail, color vibrancy and even descriptions on how games look. These are the real factors in determining ultimate shadow detail and LCD performance.

Lcd Television Wall-mounted - 5 Ways To Care For Your Lcd Television Wall-mounted

How you can Mount a Plasma Lcd Television on your wall

So that your thinking about getting a set screen (or you have) and would now like to explore the advantages to mounting it for your wall. All of the terminology and acronyms might be overwhelming in the beginning however i is going to do my favorite to describe what you ought to know. Should you already possess a lcd you are able to bypass Step One.

Step One: Choosing your kind of screen, LCD or Plasma.

It's reliable advice your thinking about a higher definition television (High definition tv). In case your searching for a conventional cathode ray tube (CRT) television you have to look elsewhere, they're a dying breed and won't be covered in the following paragraphs. HDTV's are available in number of types, the main gamers being LCD's, plasmas, rear forecasts and front forecasts. LCD means Liquid Crystal, it's not vital that you know very well what that's, just know it's the same technology that's behind the lcd computer monitors the thing is everywhere. The main focus want to know , is going to be on LCD's and plasmas because they are considered flat sections and could be easily mounted towards the wall through generally available mounts.

Allow me to squash a typical misunderstanding at this time. LCD technologies have advanced significantly and today creates a picture that's much like plasma screens. For that reasons of mounting Let me tell a couple of from the variations between Plasma and lcd. LCD televisions are nearly always likely to be lighter for his or her particular size than plasma screens. This will make mounting just a little simpler and fewer costly, as you may not require a mount that's ranked for greater weight capabilities. You will possibly not have to reinforce the mounts insertion point to your wall either. LCD's will also be simpler to move in case of a move, plasma screens are well known for cracking/crushing under their very own weight if not moved correctly.

For individuals individuals that recognize "going eco-friendly" or saving cash in your electrical bill, consider LCD's because they consume a smaller amount energy per particular size than plasma screens. You will find a number of other variations in specifications and gratifaction between Plasma and lcd but none of them which are relevant to mounting. The typical consumer/enthusiast wouldn't have the ability to differentiate, personally I gravitate towards LCD screens. Hopefully you now know which television type you'll be choosing and may go to second step.

Step Two: Choosing your display size.

Probably the most generally requested questions is exactly what size TV to obtain. Choosing the correct TV size is essential and cannot be overlooked. Whenever speaking concerning the display size remember televisions are measured diagonally (bottom left corner to upper right corner). This assumption ought to always be made when calculating unless of course particularly mentioned otherwise. The greatest factor to think about is when far nearly all audiences is going to be in the screen. Bear in mind that whenever mounting your television nearly all screens will sit about 3 inches off the beaten track. Measure what lengths your seating comes from the wall you intend to mount your screen to. Add 3 inches for your estimate to consider the mount that will sit between your wall as well as your screen. The overall rule for HDTV's may be the viewer really wants to be roughly 1.5 - 3 occasions the length in TV size (inches) in the screen. Translation: In case your television is 36 the viewer ought to be sitting at least of 54 inches in the screen and also at no more than 108 inches. You don't want to become too near to a High definition tv screen because they are created to be seen from certain distances. Sitting too close could make you question your High definition tv display quality as well as result in some serious eye strain. Should you sit too not even close to your screen your vision cannot appreciate the amount of detail as they're not going to have the ability to resolve the entire resolution from the screen. Sitting too much will even sacrifice the "immersion" feeling your High definition tv screen is supposed to provide. I highly suggest sitting somewhere in the center of the suggested viewing range. This ought to be ample sizing information for just about any home video/audio enthusiast.

Step Three: How you can choose the correct TV mount? With that said.

Choosing the correct TV mount isn't difficult whatsoever. You will find a couple of variations available to select from. The very first kind of mount I'll discuss would be the Low Profile TV Mounts, they're also known to as flat mounts or flush mounts. These mounts don't have any flexibility and hold your television screen about 1 " in the wall. These are ideal for people who are searching for a really low profile and sleek search for their High definition tv screen. These mounts could keep your television flush to wall and reduce wasted space in tight areas or small rooms. You should note, with Low Profile TV Mounts, you will likely have to take away the TV in the mount to connectOrremove cables.

The following kind of mount may be the Tilt TV Mount. Tilt mounts do just what the title suggests, they permit the screen to pitch downward for situations in which you require the screen mounted greater than viewing level on your wall. Good examples of when these mounts prove useful are stores, board rooms or sleeping rooms for when you wish a pleasant viewing position while laying lower. Different types have varied ranges of movement, the typical mount provides 15-20 levels of tilt, usually ample to satisfy individuals needs. Mounts with further tilt can be found, be sure that you look into the specifications before purchasing.

The 3rd and final mount to become talked about may be the Swivel TV Mount, also known to as articulating mounts or cantilever mounts. Swivel mounts be capable of extend the television from the wall and rotate the screen either in direction. The normal swivel mount makes it possible for the television to sit down between five to twenty inches from wall and rotate roughly 60 levels either in direction. Most swivel mounts also permit around fifteen to twenty levels of tilt similar to a Tilt Mount. I recommend Swivel Mounts for individuals who would like probably the most versatility and personalization of optimal viewing angles. They are ideal for individuals who are required maximum flexibility of the Lcd TV. Tilt and Swivel Mounts will also be well suited for individuals constantly hooking up different wires towards the TV because they allow some work room behind the screen.

Now that you've got a method of mount in your mind you have to think about the size screen. When buying a mount you will observe they are able to accommodate a variety of TV dimensions. How's this so? Most mountable HDTV's comply with agreed specifications set through the Video Electronics Standards Association or even more generally referred to as VESA. VESA refers mostly towards the hole mounting pattern around the TV and mount. Most mounts and TV's will comply with this standard but make sure to make sure before buying. Let's say you already bought a tv that's not VESA compatible? Not a problem! You will find many in a commercial sense available adapter plates which let you mount your television to VESA compatible mounts. Exactly what does all of this mean you request? Essentially, TV's of numerous dimensions will have a similar hole configuration around the rear from the screen to create finding and setting up a mount as painless as you possibly can.

The load of the TV can also be important. The load of the screen can most generally be based in the instructions or around the box, sometimes it is also located on the rear from the screen. If everything else fails it ought to be on the producers website. When searching for mounts they'll usually provide you with a maximum weight they are able to securely accommodate. Never exceed the utmost suggested weight! Worst situation scenario your screen rips from the wall and falls towards the floor departing you having a damaged TV and holes inside your wall. In case your TV is at 20 pounds from the maximum weight I usually recommend using a beefier mount having a greater weight rating. The utmost weight recommendations don't consider the load from the wires blocked into the rear of the television screen. The load or tension from the wires isn't minimal! Almost everyone has between 2 to 14 wires blocked into the rear of your screen, this extra load accumulates. Don't forget people might be enticed to the touch or lean on screen, you exert pressure when slanting/rotating it to a different position. In case your within 20 pounds from the maximum weight you will want the beefier mount, the additional couple of dollars spent here may help you save 100s over time.

Step Four: Setting up the television mount.

This information is only for use like a general guide, always follow provided instructions. When determining how high to mount your TV, the very best viewing position is definitely straight on (eye level). Should you draw a horizontal line across the center of your TV (don't really draw a line in your screen), this line should match the attention degree of your audiences. Within the situation of Tilt Mounts, you are able to mount the screen even greater and tilt the screen to pay for that height. The initial step ought to be to identify a piece of wall appropriate for that mount. Irrrve never recommend setting up TV mounts into drywall alone, no matter the load! Drywall cannot offer the weight of the screen and can easily break leading to your set to fall towards the floor. Your best choice would be to identify a stud (wooden beam) behind the drywall that you could screw into. Mounts may also be installed into brick and concrete, these installs are relatively easy as you don't need to bother with finding studs, the brick/concrete is sturdy enough by itself to carry the load. Always make certain your mounting hardware permeates in to the stud. In case your home/office utilizes metal framework rather than wooden studs, I suggest generally available toggle bolts. They may be available at a nearby home improvement store or online. Environment factors should be thought about too. There's been a current trend to hanging flatscreens over the fire place. Although this looks nice, the temperature fluctuations have proven to lower TV performance as well as to break the screen. It is possible however, however verify the wall/chimney over the fire place doesn't have temperature fluctuations in excess of 20 levels Fahrenheit. Trace levels of smoke may also result in discoloration with time. Exactly the same factor applies to baseboard warmth and radiators. Make certain the television is way enough away that it's not susceptible to extreme temperature fluctuations.

The ultimate step before drilling would be to pencil the mounting holes on your wall. You need to make certain they're level. Use a wall level or just measure in the floor and make certain the distances are equal. Take time to perform the dimensions now, an not-level installation can lead to a crooked TV, not good! This is very hard to correct and harmful for your dry wall as you'll have to re-screw. Just like father always stated, "measure two times, drill once." If you're not "hardware/construction" savvy or acquainted with the making of your house, you should think about trading inside a stud finder. Most Stud finders will identify metal and wood beams you are able to anchor into, the main one I featured will even indicate the existence of live wires. Never drill right into a wall if you're unsure whether there's live wires or plumbing behind it! If you're unsure, confused or not so confident at this time It is best to do with the money an expert installation. They may be done rather inexpensively and many companies do excellent work. For unskilled people, the price of the drill, wall level as well as other tools might be more costly than the usual professional installation. Basically convinced yourself on an expert installer I'm able to recommend among the best. ArmorMount offers an excellent on-site installation service. I have tried personally them myself and also have only excellent achievements to state. Visit ArmorMount's website directly for specifics of ArmorMount's installation service, I provided a hyperlink below.

Step Five: How can i purchase a TV mount?

There a some to select from. Getting done numerous installations I'm able to personally recommend one website that's truly great. ArmorMount.com offers the 3 mounts I spoke about earlier. They are able to supply mounts for nearly all sizes, weight and make of television. What I like relating to this clients are their Mount Finder utility. Around the primary screen from the website you just enter your TV logo and the display size, the web site immediately shows the various style mounts you can decide on. They provide all of the hardware (basics) you'll need for that installation. Their install kits come prepared to accommodate drywall, brick and concrete installations. You might also need a choice of adding their professional installation service I pointed out earlier (highly suggested for that rookie renovator). I additionally find their prices to become highly competitive, they consistently supply the cheapest prices then sell quality items. Additionally they advertise free delivery along with a 6ft High-definition multimedia interface cable with each and every purchase. Should you have had the pleasure of getting High-definition multimedia interface cables lately you will concur they're very costly and just what I say is probably the most overpriced item of the house entertainment setup. High-definition multimedia interface cables are rather convenient however, they carry both High definition tv video and digital seem as much as 1080P. They potentially eliminate as much as five separate cables (3 Component Video / 2 RCA Audio). ArmorMount also offers friendly customer support reps that we discovered to be very informative and quite enjoyable.

I think you'll found this informative guide informative. Always consult an expert if you're unsure regarding a set up and try to make reference to your instructions/specifications for that final say.

Plasma Versus Lcd Television - Glare, Response Time, and Display Size

You need to purchase a lcd TV and you're simply the inability to decide whether to choose Plasma versus Lcd Television. At the beginning instance, you need to know the question of burn-in isn't a problem because it was before with Plasma Televisions. It may be stated that it's less bad because it was using the older Plasma Television models. To ensure that you might choose which kind of TV you will buy, you will find three questions which you have to answer. Couple of recommendations are presented below.

Insights and Glare in the Screen

The initial question is that if the area in which you likely to watch the television is well lit or dark. This raises the issue of ambient light. The sunshine within the room is among the most significant factors in selecting Plasma versus Lcd Television or the other way round. The standard of images inside a Plasma Television reduces as the quantity of ambient light within the room increases. LCD Televisions generally perform better inside a well lit room when in comparison to plasma Televisions.

Lcd and plasma TV offer different display quality, and is dependent on the quantity of ambient light present within the room. A Plasma Television provides a better excellence of the images inside a low ambient light atmosphere. A far greater display quality is provided by Plasma Television inside a dark room, getting a much better contrast ratio, and dark black levels compared to a Lcd Television. Should you watch a Plasma Television inside a well lit room, the image would look dimmer than what you should get in a Lcd Television. This really is mainly because of the glare and insights in the ambient light.

However this slight condition in Plasma Televisions continues to be somewhat taken proper care of. With anti-glare screen getting used in the best Plasma Televisions, the result of ambient light on image quality continues to be reduced. The screen inside a Plasma Television consists of glass, along with a special therapy to that particular glass panel helps make the screen to face up to glare and insights from lights. The anti-glare treatment provided to the glass screen reduces the reflectivity from the glass to some large degree. If you watch the television inside a candle lit room, you aren't getting the nearby lights reflected in the screen of the Plasma Television onto your vision. If you plan to look at TV using the room lights on, it may be beneficial to purchase a Plasma Television with anti-glare coating. The very best Plasma Televisions available for sale today use anti-glare screens with the objective to lessen insights in the ambient light within the room.

Plasma versus Lcd Television Response Time

In most cases if you're watching quite happy with high-speed moments a plasma television will offer you a benefit versus Lcd Television. It is because its response time is gloomier. This puts the Plasma Television directly on top for sports, and games. Should you watch fast paced moments as sports on the Lcd Television, you will notice a blur round the edges from the moving objects. Note however that if you are using to experience games considerable time, a plasma television isn't such a good idea due to it's inclination towards burn-in. You will find LCD Televisions available on the market with fast response time, and something might get one with response duration of 5ms or lower. You just need to bear in mind when crisp picture is essential for you personally, a minimal response time (high refresh rate) is really a feature you ought to be searching for.

Display Size

If you want a sizable lcd, Plasma Television provides a slight cost edge on LCD Televisions. Also, presently you will find no Plasma Televisions on the market below 42 inches, but it's likely that we'll soon see Plasma Televisions with 32 inch display size. So essentially if you prefer a small High definition tv your main choice is an Lcd Television.
