LCOS is used in order to produce large and enhanced image to raise the viewing experience. For most of us, it would be a new technology but the reality is that it is not widely used in the past. Like other HD technology, LCOS too guarantees picture clarity and is used in all kinds of televisions like front and rear projection. This technology uses silicon semiconductors in order to direct electric current in one direction. In case of LCOS, there is no need of using and turning tiny mirrors on and off. Instead, it uses liquid crystals that when energized forms a path of light.

When light passes via LCD panels towards lens, it gets modulated by the liquid crystals when light passes through it. You can call it as transmissive technology. LCOS combines these two innovative concepts. Instead of using tiny mirrors, it uses liquid crystals. Opening and closing of these crystals will decide whether the light will reflect from the mirror or it will get blocked. In this way images gets displayed on the screen. It uses layers of liquid crystals that control light on individual pixels. Under basic components of LCOS technology comes lamp that provides white light, one splitter that is used to split up incoming single-color light into primary colours like red, green and blue. Mirrors are used to separate various colours that falls on separate LCOS devices. Later on these colours are combined using prism and colour image is magnified and displayed on the screen. Image produced must be magnified in case of LCOS system because it generates sharp and small image. Pixels generated using this process are natural and smooth.

Such an enhanced concept will definitely demand high price. Products using LCOS technology are much costlier than other LCD or DLP products. In terms of weight, don’t compare LCOS products with DLP and LCD units. Even the lightest LCOS product weighs 12 pounds. Due to so many factors like high price and heavy weight, this technology is not released in the market that deals with cheap portable projectors. You can notice that in today’s world, people still prefer to go for cheap and best monitors and that uses LCD and DLP concept. This is the reason why LCD and DLP get more attention than LCOS. No one can deny this fact that LCOS is the future technology in television world.

It’s not so easy to develop this technology widely for televisions but one thing is sure that whenever this technology will enter in the market, it will make LCD and DLP monitors dull.

Before heading towards any showroom, make sure that you do your homework very well. Check out the reviews of HDTV from newspaper, magazines and internet. Very few sites actually discuss correct features of HDTV, so make sure that you read elaborately on this. Check out every model of HDTV from the manufacturer’s site and if you are getting manual online, go through it very carefully. In the market you will find three kinds of retailers. First, that has big showroom that may not find it important to discuss every single detail of HDTV, as they have many customers to handle. Second, medium size showroom that may highlight only special features of HDTV and last small size showroom that normally will spend a lot of time with customers explaining them the necessary pros and cons.

In most of the stores, you will find continuous running demos on HDTV’s, but don’t get impressed by the looks. Such ads are designed in such a way that every television shows perfect quality of videos. If you are looking for HDTV, make sure that every single HDTV available in the showroom shows same video content at the same time. Ignore animated videos, artificial images as they cannot show the exact video quality of any HDTV. You may find the brightness and contrast perfect at first sight but that may not be true. Try to check out all the important features of HDTV that you want to purchase. Many HDTVs deliver analog feature instead of digital. Apart from having cheaper cost, analog may face various issues that can directly affect picture quality of the television. Never judge video quality of any HDTV by its video content, instead go for image slide show as it works best if you are checking out picture quality. By looking at image slide show in all the HDTVs available in the showroom, you can very easily select the one that you are looking for your home. You can bring your own photos too in pen drive to check them in HDTV via USB port. Ask for remote to a sales person and set TV to cinema mode and then check out your images.

Try to avoid HDTVs that have glossy screen as they may produce ripples in the image when they are not glued properly. You can check out for the ripples when screen is turned to black. You can bring black picture along you by click a snap with camera lens off. In this way you can check out for the ripples in HDTV. In HDTVs picture changes with change in viewing angles, especially in case of LCDs it can be seen every easily but plasmas may have minor effects. In this case too, you can use black photo to check out at different viewing angles. Most of the HDTV has fan noise problem that cannot be heard in noisy store. So try to look out for this issue too, as we don’t want you to get shocked when you hear the same noise at home.

Small efforts like checking out every important feature of HDTV in manual and practically on television can actually help you in investing your money on the best quality HDTV.

• With a 30 inch display and a high resolution (such as 2560×1600) you can easily open up several windows at the same time without having to scroll around and move back and forth. This is a blessing in disguise for people who are constantly updating or editing photos. Because of the high resolution you can even see every minute detail in your photographs allowing for better photo editing. The 30″ (76cm) display along with a 2560×1600 resolution and 16:10 aspect ratio calls in for clear images and allows for exceptional multitasking.
• The Dell U3011 30″ Monitor comes calibrated from the manufacturer for both sRGB and Adobe RGB color profiles, therefore when editing pictures you are sure to get accurate colors. The 117 % color range with excellent Adobe RGB and sRGB coverage provides for colorful, vibrant and lifelike visuals.
• The monitor supports the IPS (in-plane switching) technology therefore the color deviation across wide viewing angles is minimal. Because of the IPS technology the gamma and contrast are very accurate. The IPS panel does not suffer from color deviations and contrast at off angles that normal TN panels suffer from.
• It also is easy to use, versatile and supports some of the latest connectivity options such as HDMI, USB ports, DVI-D, DisplayPort and a 7-in-1 media card reader. You can easily connect to peripherals or share data via the four USB ports and card reader.
• The monitor is also very good in motion. Whether you are watching a video or creating it, it provides for a razor-sharp  and ghost-free viewing experience on moving images because of the 7-millisecond (gray-to-gray) response time.

The DELL U3011 is very easy to use as well. You can easily adjust the height and tilt it to fit your viewing needs. If you have space constraints, then you can detach the panel from the stand and mount it on the wall, saving a lot of space. Also the screen features capacitive touch switches for setup and screen optimization making it easy to manipulate.

The swivel base is very convenient especially when you are meeting with clients. You can just swivel the panel to show them pictures that you worked on. It just takes a few seconds to get it back to its original position. However the monitor doesn’t come cheap, but then the features are just so great that you will that every penny you’ve spent on it is just worth it!

The monitor comes with 3 yr warranty and a good help and support system from the company. It also is environmentally friendly as it comes a 5 star rating.

• Display – The display is the most crucial factor for any monitor. Flat screen monitors are very popular these days and they come in various different technologies. Currently, the best monitors are those that are made with IPS technology (in-plane switching technology). Any monitor with broad range contrast ratio and high levels of brightness will render brighter colors and greater color depth. LED monitors will have the best of both. When purchasing a monitor you must even look at the response times to lessen the blur from on-screen movement. Also select one with a wide viewing angle so that the image on the monitor can be viewed clearly even from a broader corner area of a room.
• Features – Since people and desks come in different sizes and shapes, monitors should also have the facility to adjust its height, swivel and tilt. Most monitor models will not have the above mentioned adjustments. If you are have a space constraint on your desk at home, or if you would like to have more space, you can choose a hanging monitor that can be mounted on the wall behind your desk. Some monitors even have speakers but these speakers cannot reproduce the similar kind of audio quality level as compared to any audiophile. Apart from these features, it is also important to take note of the weight, dimensions and the power consumption of the monitor before purchasing one.
• Connections – Different monitors have different types of connections. Select one that has the same connections as that of your graphics cars, otherwise you will need to purchase a converter cable which is most likely to be sold separately. Most monitors nowadays come with connections such as VGA, HDMI, DVI and DisplayPort. Some monitors even have a USB hub which can be used to connect to additional USB peripherals such as the webcam.
• Help & Support – When purchasing a monitor it is important to check on the help and support system provided. Choose the brand that offers a good customer support system and also one that meets your personal needs. Also check with the warranty period. Most companies will guarantee their monitors for a period of one year. Warrantees for a period of more than 1 yr are far more comforting than those that only last for one year.

These are some main features that you need to bear in mind while purchasing a monitor. The differences in the above mentioned features will help you buy a monitor that will be right for you.

• Response Rate – Response Rate is the term used to define how quickly the pixels on the monitor can change color. The lower the response rate, the faster the pixels can change color. This is very crucial especially when you are playing fast-paced games. A slow response rate for a fast-paced game could lead to “Ghosting”, which means the previous images on the screen will appear hazy for a few moments before the image changes. Therefore, while choosing a gaming monitor, you need to choose one that has a lower response rate. It it should have a minimum of 5ms as response rate. Any monitor with a response rate lesser than 5 ms is obviously better.
• LED vs. LCD Monitors – LED and LCD monitors are exactly the same except that LED monitors use LED backlighting, therefore it provides for a much brighter and sharper display. LED monitors are also slicker and thinner and it consumes less power as well. However, the cost of an LED monitor is greater than that of an LCD. In terms of performance, both are good as long as they have good response rates.
• Size of the Monitor – The size of the monitor ultimately depends on you and how much are you willing to shell out for a monitor. A large screen will obviously be more expensive than a small screen monitor. For the best gaming experience, you should have at least a 19″ monitor.  If you have a bigger budget then, go for a 23-25 inch screen. A widescreen monitor is also good for a great gaming experience.
• Contrast Ratio – Contrast ratio is necessary for a better image quality. The higher the contrast rate the better the image quality.  With a higher contrast ratio, your monitor will be able to produce more immersive and visually sharp pictures.
• Viewing Angle – If you view an LCD monitor from an angle, you will notice that the images appear dull and colors look odd. At extreme angles the complete image can even vanish. Therefore, the viewing angle of a monitor is the angle at which you can still view the screen clearly. The viewing angle is generally listed in the monitor’s specification list. The greater the viewing angles the farthest you can view clearly. Generally for gamers the viewing angle isn’t that important because you will generally look at the screen directly and straight. But for some people the viewing angle is very important, especially if you are using the monitor for presentations.

I hope that these tips will help you make a better choice while buying a gaming monitor. The above tips will definitely put you in a better position to buy the right kind of monitor so that you have a magnificent gaming experience.
