Flat Screen Monitors: A Technological Wonder

You probably are already aware that there are two types of computer monitors available today: the big and clunky cathode-ray (CRT) tube monitors and the newer flat screen monitors. These flat panel monitors have a number of advantages over the older type of computer monitors. They are far sleeker, more space-saving and weigh much less. Flat screen monitors are also designed to be more energy-efficient and reduces eye strain. Flat screen monitors use the technology called Liquid Crystal Display or LCD. There are also flat screen CRT monitors available. Both LCD flat panel monitors and CRT flat-screen monitors are fast gaining popularity as a much sleeker and more modern alternative to traditional, bulky monitors of yesterday.

An LCD or liquid crystal display is characterized by a thin and flat display device that is composed of either color or monochrome pixels that are arranged in front of a light source or a reflector. There are two types of LCDs: transmissive and reflective displays. These types differ according to the source of light. A reflective LCD is illuminated by exterior light. A common example of a reflective LCD is the display of a digital watch. Meanwhile, a transmissive display draws its light source from the back through a backlight. This category of LCDs usually requires high luminance levels. Televisions, computer displays, PDAs and mobile phones use transmissive LCDs.

Flat screen monitors have significant advantages over the traditional CRT monitors. Because these monitors are perfectly flat visually and physically, they offer a clearer, more vivid and undistorted pictures from any angle. The images on a flat panel monitor is much more crisp and high quality. This is the reason why flat screen monitors significantly reduce eye strain among its users, another important advantage. There is no curvature on the screen’s surface that will distort any on-screen images. And since the pictures are sharper with more brilliant colors, staring at a flat screen monitor becomes more of a pleasure than a strain.

Flat screen monitors are also much more ergonomic. This means that these types of monitors follow ergonomic requirements and thus add comfort and convenience for the worker. The flat screen monitor is viewable from any angle and is typically fitted on a swivel base with adjustable headlight. This allows for more freedom of movement for the user since the flat screen monitor can be easily adjusted to meet the specific viewing needs. Flat screen monitors are also very space-efficient taking up less desk real estate than older computer monitors. Most LCD flat screen monitors are only about an inch thick and weighs nearly five kilograms.

If you are planning to buy a new flat screen monitor, there are some aspects you should consider. First, choose the resolution that is most appropriate to your needs. Next, assess the price. Generally, flat screen monitors will cost you about $200-$250 for a CRT screen while LCD flat panel monitors cost $500 to $700. Both LCD and CRT flat screen monitors have an average lifespan of about 5 to 7 years, and also come with warranty ranging from 1 to 3 years. Before you purchase, make sure that you do your research on the many different brands of flat screen monitors available in the market today. A flat screen monitor will definitely enhance your computing experience, whether for work or for play.

Finding The Right 27” LCD TV

A 27” LCD TV provides a much better picture than the old CRT televisions – and they come in much more attractive styles. In many homes an LCD TV has become an integral feature in the entertainment room’s decorating scheme. They’re versatile, too. A flat screen 27” LCD TV can be mounted on a wall, under a cabinet, on the ceiling, or it can sit on a stand or on top of furniture. A 27” LCD TV comes in a size that is big enough to comfortably watch from a reasonable distance, but it’s also small enough to fit in even the smallest viewing rooms.

The 27” LCD market is also highly competitive – almost every television manufacturer makes at least one 27” model. Choosing the right model for your needs can be time-consuming; to get you started, take these steps as you search for the right TV for you.

First consider your room’s décor, and think about how you’ll sit relative to the TV. Because a 27” LCD TV has significantly higher resolution than a conventional TV, you’ll be able to sit closer than you normally would and view a larger screen much more comfortably. The optimum viewing distance for a 27” LCD TV is approximately 6 feet, so plan your furniture arrangement accordingly.

Then make a decision about whether you want or need HDTV. A 27” LCD TV with EDTV is less expensive to purchase but it won’t display high-definition signals. The price difference between a smaller HD-ready 27” LCD TV and an ED-ready 27” LCD TV is relatively small, so you’re better off buying an HD-ready set. Many experts indicate there’s little reason to buy a non-HD 27” LCD TV. A lower resolution LCD TV won’t be able to accept high-definition signals, so the picture won’t look any better than regular analog TV. In the next few years more and more TV signals will be in HD; since your 27” LCD TV should last for more than fifteen years, make sure it will grow with the technology.

Now try to purchase a set with an HDMI input. This port keeps the signal all-digital, avoiding degradation that can occur as the signal passes through other components (like your cable box). HMDI carries high-definition audio as well as video. Some satellite receivers and DVD players also connect through this port.

Narrow your choice of 27” LCD TV down further by determining if you want or need picture-in-picture functionality. Picture-in-picture allows you to view two video sources at once, with one appearing as a small window on the screen. If you do want picture-in-picture capability on your 27” LCD TV, remember that single-tuner picture-in-picture lets you watch television in one window and another source (like a DVD) in the second window. A 27” LCD TV with two tuners lets you watch two television sources at once. It’s a cool feature and once you have it you’ll find you don’t want to do without it, especially if you’re a sports or news junkie.

You’re almost done, but now you’ll want to check to see if the different models of 27” LCD TV you’re still considering are sold with a stand or mounting hardware included. Most 27” LCD TVs will come with a table stand wall mounting hardware costs an additional $100 to $200. If you do purchase a stand or mounting hardware separately, make sure it’s appropriate for the size and weight of your TV. The average 27” LCD TV is pretty heavy, so it pays to make sure your stand or hardware will safely support it.

Last, but certainly not least, inspect the manufacturer’s return and warranty policy before buying online. Some manufacturers have strict policies regarding authorized dealers. If you buy a 27” LCD TV from an unauthorized dealer, the manufacturer may not offer warranty coverage. The retailer may offer a substitute warranty that sufficiently covers you – the only way to know for sure is to ask.

The price difference for a 27” LCD TV from an authorized dealer and from a discounter can be hundreds of dollars – and sometimes that’s the sole reason for the price difference – so make sure you’re comfortable with the risk of not having a warranty, or make sure you ask the discounter for information about warranty terms for the 27” LCD TV you’ve narrowed your choice down to.

Digital Voice Recorders

Using digital voice recorders in every day life has become so commonplace that most people do not even give it a second thought.

Digital Video Recorders

Digital video recorders (DVR) are recording equipment that can record and store digital video on a computer. These can record audio as well as video data from multiple sources.

A DVR is basically a hard drive that can be connected to the computer and to other video sources such as a VCR. It has a tuner which captures the signal using a cable, antenna, or a satellite. The analog signals are compressed and converted into digital signals, which are then stored on the hard drive. A built-in MPEG-2 decoder converts the digital signal back into analog signal when it has to reach the television for viewing. Each DVR has an operating system within the hard drive.

There are several advantages to digital video recorders. They do not require a recording medium like tapes, as the data is stored on the DVR itself. Another main advantage is that the recording and playback can be done at the same time. Using this, even a live program on the TV can be paused, in the sense that the program can be recorded on the DVR and then viewed instead of the live program. However, the space within a DVR is limited, which is its main disadvantage. DVRs also have a live-TV buffer that keeps them in a constant recording mode for an hour or more.

Another interesting feature of DVRs is their search tool, which allows searching of a particular program by name of the program, name of the actors, or even by keywords. Some DVRs can be programmed to record some programs that have certain words in them. DVRs have recording capacities ranging from thirty hours to 320 hours. This also depends on the quality of the stored files.

The main categories of digital video recorders are TiVo, ReplayTV, and UltimateTV. Some of the top manufacturers of digital video recorders are LG, Panasonic, Philips, Pioneer, RCA, Samsung, Sonic Blue, and Sony. Prices range from $600 to $1,200 or more, depending on the brand, the model, and the options provided.

Digital Video Cameras – More Fun Than Ever

With your trusty digital video camera by your side you can capture all those special moments, such as your child’s first steps, your birthday or wedding, or your vacation with family and friends etc.

With so many manufacturers and models available in the digital video market, you may find it confusing trying to choose the perfect one for you. Your choice will, however, depend on the features that you want and how much you are willing to spend.

The most important thing to consider is the format in which your videos will be stored, as the video format determines the video quality. Digital 8 otherwise called D8, Mini-DV, DVD and HDD are the main types of video format that digital cameras offer. Both D8 and Mini-DV are tape-based formats, with the Mini-DV currently offering the highest quality video format to consumers. The DVD format allows direct video recording onto a digital disk, while the HDD type uses internal hard drives where the video is recorded. As the tape format is slowly being phased out by major manufacturers, it is a good idea to invest in disk or hard drive based digital video cameras.

Digital video cameras also come with charged coupled device or CCD imaging sensor. Digital video cameras come with 1-CCD or 3-CCD features. Cameras with 1-CCD suffer from poor video quality, whereas 3-CCD cameras produce much better quality videos. Most professional camcorders use the 3-CCD technology, thus making them more expensive than the other models.

The optical zoom feature of the camcorder lens generally ranges from 10X to 20X. The choice of zoom depends on how close you want to get to the action. Some digital video cameras also allow still photography at various resolutions, and some camcorders offer both video and still photography features. Some digital video camcorders have in-built flash for low-light photography, while some video cameras come with a ‘Night Shot’ feature. Other popular options include external flashlights, external microphones and external storage devices that can be attached onto the camcorder.

Camcorders with longer battery strength is also recommended. Digital video cameras have battery life ranging from 4 to 8 hours of continuous shooting. However, using the zoom or any external devices reduce the battery strength.

All cameras nowadays come bundled with a digital video editing software. But if you are not satisfied with the one provided, you can always buy a better and more expensive editing software from Adobe or any other reputable brand.

Video camera prices today vary from $500 to $4000, with Sony, JVC and Canon being the more popular brands.

Cameras – Pictures Capture Time

The magic of capturing the smile of a beloved, the blending hues of a sunset, the expression on a baby’s face, sends thrills of anticipation to people of every culture,of every age.

What was considered a miracle two hundred years ago now casually blends into one’s every day activities.The
invention of the simple black box in France started an industry that has evolved as fast as the technology required for any new-age product.

Cameras now come in price ranges that allow you to even throw them away after taking one roll of pictures.They also come in the most complex, computerized packages that only the richest pros consider purchasing.

Although the original concept of the camera began to be developed around the 1830s, it wasn’t until around the 1900s that more people could afford to buy one or have the film developed or have their picture taken professionally.

By the 1930s and 1940s, cameras acquired a permanent niche in the hearts of the average person. Since then thousands of brands and models have appeared, only to be replaced with the newest technology of the day.

In order to focus more precisely, the earlier camera had a bellows, allowing the distance from the lens to the film to be adjusted.

The greatest fear of those owning the bellows-style camera was an accidental, fine pin-hole that allowed unwanted light in.Being opened and closed hundreds of times tended to create cracks in the corners where they folded.

The leaky bellows problem ruined many a picture, to the sorrow of the photographer.

Features the photographers wanted, and after a while received, were film on a roll rather than having to use a plate. Next came film stop mechanisms so that winding the film to the next spot became more accurate.

Features that kept one from making double exposures delighted many
photographers. Adding flash in such a way that it was actually usable surged the sale of cameras forward.

Just as the movies were originally silent movies and only came in black and white, the first still cameras only used black and white film.

The two industries moved forward on parallel paths. Once color film technology existed for one, the other quickly adapted its products. Colored slides and slide projectors became favorites for taking those vacation pictures and showing them to friends.

It wasn’t long before a regular homeowner could make a color movie of the kids. When sound was added to the movie theaters, the movie fan began adding sound to the home movies. That home movie film was sent to a professional developer for processing.

The speed of technological inventions increased. Along with computers in every home came the age of the Video Camcorder and the Digital Camera. Instant pictures! Instant movies.

No developing necessary. Everything happens with instant playback!

One aspect of the camera industry hasn’t changed over the years: the thrill, the magic, of capturing a moment in time,to be treasured and shared with the world.

Cameras have reduced the size of the planet in our mind’s eye and fostered understanding among the different cultures and races of the world.

This is a camera’s most priceless quality and gift.
