LCD Projector- Buying Guide

There is simply no finish to innovation. Mutually new innovation surpasses another, technology has gradually morphed into a superior force that dominated every aspect of our lives.

Every technological innovation is measured by the dint of its output. LCD projector is the name that tops the list. Nowadays, LCD projectors are a necessity. It is an integral half of each business meetings, seminars and conferences. The origin of LCD projectors dates back to 1971 when Gene Dolgoff for the first time used liquid crystals to modulate light. And it absolutely was in 1981 when for the primary time LCD (Liquid Crystal Display) projectors were introduced in the market. The technology behind these projectors is very complicated. A lightweight beam sent from metal halide lamp through a prism. The prism segregates the sunshine into 3 poly silicon panels for 3 totally different components of video signals. As lightweight passes through these panels, the individual pixels are opened to pass and closed to dam light. This terribly combination of pixels produces a wide range of color in the projected image.

One of the best benefits of LCD projector is that it is highly portable.

The value of the transportable machines are a comparatively above its primitive counterparts.. The lightest model offered till date weighs less than 5 pounds. Whereas you buy a light-weight weight LCD projector, you should not forget to think about the weight of the case where it is encased.

There are some necessary factors to be borne in mind whereas you agree for getting one.

Firstly, the screen resolution should suit your usage. The resolution that works fine for a PowerPoint presentation might be a total misfit for showing statistical data or numerical figures.

Secondly, the dimensions of the lumen should be in conformity with the place where the projector would be used. A lot of the number of people, the better should be the brightness of the images. A one thousand to 2000 lumen projector would work fine for a medium sized room. Again, whereas you are presenting something during a seminar, you wish a projector with higher lumen.

While shopping for LCD projectors, one ought to go for quality. It is advisable that you select the one that includes a durable lamp. Most LCD projectors today have a lamp life of 1000hrs and this may go up to 4000hours. Replacement bulbs might ultimately value you more within the long run. It’s always better to refrain from using halogen lamps since they exhaust when seventy hours and produces a yellowish tinge on the images.

One must doubly ensure that the projector he buys is video compatible. Whereas composite video input allows you to attach video players, part video inputs permits you to attach directly to DVD Players, digital VCRs and HDTV tuners. The HDTV(High definition television) signals are digital and supports a higher resolution.

Last however not the least; a projector should continuously be ideally positioned at the centre of the screen. If that is not done, the pictures are projected at an angle and may appear distorted. The keystone correction feature adjusts and enhances correct positioning of images.

Expert’s Guide To Buying A Digital Projector For Education Or Business

Buying a digital projector means focusing on seven key points that give a price and performance comparison across brands.

The problem is manufacturers try and muddy the market by making comparison difficult.

Before considering any projector, make a mental note of what the digital projector will do for your business or organisation, where it will be used and the budget.

This sets parameters for the reseller that lets them make sensible recommendations.

For each digital projector, cross-compare these seven key points by award points out of 10 for each category that should give one or two products that meet the specification required:

Resolution

The higher the screen resolution in pixels is reflected in a higher digital projector price. Match the projector to the place where it will be used and what will be displayed.

PowerPoint presentations in small rooms or classrooms are generally fine at a low resolution.

Brightness

These depend on the light output, measured in lumens. A projector output of less than 1000 lumens may not give a clear image. Presentations in rooms with bright lighting left on probably need a high-performing LCD projector.

Contrast

Contrast is the ratio between the lightest and darkest areas of an image. Look for a ratio of 400:1 or more to get a balanced image.

Portability

If a digital projector is static, weight doesn’t matter, but if someone has to carry the equipment around together with leads and cables, a lightweight model in a tough case is better. Portable digital projectors can weigh in at less than 5lbs, but less weight can come with a heavy price tag.

Connectivity

Check out the devices that need an input on the projector and make sure the model has the right jacks and plugs plus a couple spare. Consider the computer that will input as well – is it a Mac or a Windows machine and will the digital projector’s software and/or drivers run on it?
All these factors have to be considered to make sure a projector delivers maximum usability.

Lamp life

Replacing digital projector lamps is expensive. Look for a machine that has a listed lamp life of 2000 hours and any power saving options as extras like lamp management features to extend lamp life.

Warranty

Other key points that affect price are projector and lamp warranty. The longer and more comprehensive the warranty generally pushes the digital projector price up.

Don’t forget to check out the support that’s available from the reseller and the availability of spare lamps.

If the cost is much less than expected, find out if the projector is cheaper because it’s an end-of-line and whether a new model is due.

Should the price come in more than expected, the digital projector could be a new model with early takers paying over the odds so the maker can reclaim R&D costs.

Lastly, don’t make a quick decision – ask the reseller to provide a range of choices and request a demo in the room where the digital projector will be installed if possible.

How Big Should It Be
Home theater projectors usually aren’t that big. A good projector should generally be between 5-7 pounds, be able to fit under a bed, and come in a carrying case. It should not be a massive machine like those old clankity projectors that you remember from high school – the ones on that little cart and the teacher would write on the sheets of translucent paper. No, modern day projectors are much better and are even half the size of most PC towers.

Should It Make A Lot of Noise
Your projector probably will make some level of noise because the fan on the inside of the machine has to spin really fast in order to keep the projector cool. If it overheated, you can say bye-bye to Mr. Projector. Have you noticed how at your computer desk, you can hear a slight high pitched sound coming from the computer? That’s the fan – you probably won’t hear anything louder than this coming from your projector and at many times, you will hardly notice it.

Features
Be sure to get a projector in which you can adjust the lens in order to have ultimate viewing pleasure. Also make sure that you have a bright lens that has a high level of lumens and a high resolution. This is to ensure that you can get maximum quality from your projector as most computers run on higher resolution these days. If your projector does not meet the requirements of the computer that you’re using, the projector will automatically compensate by making the picture a little bit smaller. Normally, you won’t even notice this, however, it might make smaller objects in the film even smaller.

Those are the basics and should get you by when you’re out shopping for your projector. Projectors can range anywhere between $500 and $3000, but a projector on Ebay that costs a good $500-$600 will be more than enough to meet all of your requirements. The more expensive brands are just glamour and un-needed quality – like when you buy a new computer and it has 500 GB of hard drive space. You’ll never use that much. So be smart, be safe, and enjoy your new home theater projector.

So you’ve decided you want a projector, but you don’t know where to begin? Don’t panic, in reality, there are only a few simple decisions you need to make, to know what projectors will be right for you. Before you begin, you want to decide whether you will be using your new projector for displaying movies, playing video games, or giving presentations. This will affect how bright or dark your viewing room is and what resolutions you need, plus things like connection options. Also work out where you want to place your projector relative to its screen.

To begin with, you will need to consider brightness and contrast. Most projectors have their brightness stated in two ways, Lumens and foot-Lamberts. Sadly the Lumen rating is not a really useful gauge of brightness, as it often does not take into account the viewing size of the final image or reduction due to normal rather than max usage. In dark conditions such as a dedicated home theatre room, look for a brightness rating of around 40 fL, and increase it depending on how much extra ambient light your viewing room will have.

Contrast is often a more useful measure of projector quality than brightness. A high-quality projector will have a contrast ratio of 5,000:1 or more, all though check to see if the projector uses a “dynamic iris” to help boost its contrast range. These work by restricting the light output in dark scenes, allowing the projector to produce “blacker blacks”. Many such projectors will also just quote “on/off” contrast, which is the difference between a full black and full white screen. A better measure is ANSI contrast, which uses a chequered test pattern, and measures the difference between the light and dark squares. This value will be unaffected by any dynamic iris, and is usually a lower value.

Next you need to think about the supported resolutions you want to display. The very best is 1080p,so called “full HD”, and will allow you to display Blu-Rays and other high-definition content properly. Most games and computer presentations will only need 720p or 1024×768 resolution, so if you won’t be primarily watching movies, save some money and go for a lower-spec model. 1080p and 720p are both 16:9 widescreen resolutions, whereas 1024×768 is 4:3, which is a more square standard used by many computer monitors and older TV’s. Consider the screen you will be displaying on. To get full use of the screen, make sure it’s resolution matches that of your projector.

Finally, make note of the “throw distance” of the projector. “Short Throw” projectors are designed to be placed closer to the screen and still produce a big image, whereas “long throw” projectors are the opposite. Also quoted will be the amount of zoom available, which will allow you to grow or shrink the image somewhat. Another useful feature on most projectors is lens-shift. This will allow you more flexibility in placing the projector relative to the screen by enabling you to move the image up and down or left and right by a certain amount without distorting the image.

A projector is just a key word that covers a large variety of types according to the need of the consumer.

Starting with the basic overhead projector, there can be LCD projector, digital projector, slide projector, video projector, front projector, light valve projector, DLP projector, movie projector, cine projector, CRT projector, dip projector, home theatre projector, or very latest pico projector etc. as a consumer you are pampered with a wide variety of brands that manufacture projectors.

LCD and DLP are the two techniques used by digital projectors. HP and Samsung are the market leaders in both these technologies.
