With advancing technology and lowering price of various tech equipments, projectors have now become a common and quite essential commodity in every sphere of life. Be it for office use in conference rooms or for use in educational institutions or as home theatre projectors, they are becoming popular every day.

Nowadays there are numerous brands selling projectors in the market, and so you must know some important things before going to buy a projector. And we are here to help you select the best product for your needs.

What are LCD and DLP?

Whenever you go to shop for projectors you will often hear these two words. LCD and DLP are both display technologies which are used in projectors. The full form of LCD is Liquid Crystal Display and that of DLP is Digital Light Processing.

DLP is mostly used in high definition projectors because of its high contrast ratios, smoother video quality and high definition images due to less visible pixilation. Thus they are mostly used in movie projectors and Home Theatre Projectors.

LCD on the other hand has lesser definitions and is thus used in office projectors or for presentations. However a latest convention of LCD is 3LCD which makes its faults a thing of the past. Thus they are now being used in many high definition projectors too.

However there are drawbacks to both. LCD is mostly susceptible to "latticed flyscreen" effect whereas DLP suffers from the "Rainbow Effect" on its edges.

Multiuse Projectors

With increasing demand of projectors in all spheres of life it is either not possible to afford many projectors by a single person for multiple purposes, nor does everyone have ample space for storing all those projectors. Now there is an easy solution – Multi-use projectors.

These projectors are very compact and can handle presentations as well as DVD playbacks pretty well. Some also include onboard stereo speakers as well as wireless connectivity. They come with a remote control and also have vertical and horizontal keystone correction. They are quite affordable now and are of great use.

Home Theatre Projectors

Nowadays people who love watching movies are turning to Home Theatre Projectors rather than Plasma TVs or LCD TVs. This is because projectors come at half the price of Plasma TVs and offer you all the qualities that a good LCD TV will offer you. These projectors support wide screen projection and can project a picture in high quality, double the size of any Plasma TV. They also offer a wide selection of video input ports.

A home theatre projector usually offers 16:9 aspect ratio which is equally good for movies as well as gaming solutions. You can also plug in your Playstation or Xbox and enjoy high definition gaming experience.

Models available in the market –

Sony "SXRD" and LG "LcoS" – These models are low priced and use a unique technology of spinning color wheels. They use three color panels thus providing better color and picture quality. There are thousands of inbuilt tiny mirrors which reflect light to give you a crystal clear image.

Epson Dreamio EMP-TW700 – This is a high definition projector with inbuilt DVD player and onboard speakers. It is a great option for Home Theatre Projectors as it provides excellent picture and video quality.
