What to Look For
So you’ve decided to buy a projector. But, you may be confused as to how to choose the right model. There may be many questions regarding terminology, features, and other important aspects which you need to take into consideration before making your purchase. Let’s take look at a few factors that should be considered while buying a projector, shall we?
Colour Brightness and White Brightness
There is a wide range of projectors available online which provide different levels of brightness which are measured in lumens. The higher the lumen rating, the brighter the projector will be. There are basically two lumen specifications that you should be looking for - one for the colour brightness and one for the white brightness. If there’s only one lumen rating specified, it usually refers to the white brightness of the projector. The colour brightness may be as little as one-third of the lumen rating. So how do you know which lumen-rating is ideal for your room? The room in which you’re going to be using the projector determines the amount of brightness you need. For home theatre use, you would need a projector with a minimum lumen rating of 1500. For classroom or conference room use, a projector with a minimum lumen rating of 2500 is best. If you’re going to be projecting in large auditoriums or lecture halls, then you would need a projector with a higher lumen rating.
The picture that you are projecting may have light and dark images. The contrast ratio is basically the difference between the light and dark which is expressed by a number. It is the comparison of luminosity between the brightest white and the darkest black on a screen. For example, a 1000:1 contrast ratio represents that the brightest white is thousand times brighter than the darkest black. So what is the use of contrast ratio, you ask?
A high contrast ratio directly results in a rich, detailed, and crystal-clear image. At home, the ambient light might hinder the cinematic experience you require. Hence the contrast ratio is especially important for a home theatre.
It basically means the number of dots or pixels used to display an image. The higher the resolution, the clearer the image. The difference between a high-resolution image and a low-resolution one is that there are more pixels in an image with high resolution. This results in a crisper and cleaner image. This is usually indicated by a number combination such as 1920 x 1200. This means that there are 1920 dots lined horizontally and 1220 dots lined vertically across the display.
Other aspects to consider include the connections, light sources, and accessories. So what are you waiting for? Armed with the above information, you can browse online, compare different models from different brands and choose the right projector that meets your requirements. Make your movie nights memorable by choosing the right model of projector. Be it a classroom or a boardroom, it is time your presentations come to life!
