How to choose best projectors?

Big-screen TVs have become much more affordable in recent years, but a front projector is still the ideal option for those who want to watch their shows on a massive screen. However, it might be difficult to select the best projector from the many available types, which can cost anywhere from a few hundred to several thousand dollars.

There are a wide variety of projectors on the market, each one optimized for a certain task. Here are some important questions and answer before you go out and buy a projector.

In your own words, please explain what a projector is.?

A projector can be conceived of as a camera turned on its side, emitting light rather than capturing it. This buying guide will focus on digital projectors, which are projectors that accept video inputs and hence act like a television or computer display while also providing additional advantages:

  • Enhanced picture size

  • Superior portability

  • Possibilities for adaptable set-up

In what kind of a space will the projector be used?

For cinephiles, the answer to this issue is crucial since it determines how much money should be spent on a projector. Do you watch movies only at night with the lights out, or do you have a special theater room where you can completely filter out ambient light? 

Do you want to experience your favorite dark and melancholy thriller in all its cinematic glory? If that's the case, a high-end home theater projector's extra cost could be justified by the superior picture quality it provides thanks to its deeper black levels and greater contrast ratio..

It's also important to think about how much space you have in your bedroom. To cast a huge image, traditional projectors require a lot of room. As a rule of thumb, a distance of at least 100 inches is required between a projector and screen in order to produce a 100-inch image. A projector with a short-throw lens, which can project a larger image from a shorter distance, may be more suitable for a cramped environment.

The light from a projector comes from what exactly ?

Typically, LED and metal halide lamps are used in projectors. The use of LED is still limited to portable devices such as projectors. Metal halide, a type of tungsten lamp, is utilized by nearly all the rest, and it has a lifespan of 2,000 to 5,000 hours if left on at its standard brightness. Only a small number of setups make use of hybrid technologies that combine LED and laser illumination.

In what range of luminosity should I be looking?

Light pollution is an absolute must if the projector is to be utilized for any sort of critical viewing. If this isn't an option, then monitors or televisions (perhaps organized in a "visual wall") should be utilized instead. Any effort put into calibrating the projector or correcting the colors in the image could be rendered useless if the room is too bright. To begin with, projectors probably aren't the best option for critical watching, and they're especially not great when there's ambient light.

Keystone adjustments and lens shift?

Most projectors have lens shift and vertical or horizontal keystone correction. The trapezoidal "keystone effect"—when the projector is too low or horizontally off center, the image seems bigger at the top or on one side—is well known. Keystone correction corrects this to a particular percentage. Keystone correction is digital, like camcorder zoom. Applying more degrades the image. If the projector is mounted at a straight angle to the screen, the lens should not be below the bottom or above the top. If you are stacking or edge blending, consider a projector with lens shift. Lens shift optically "repositions" the image without affecting image quality. High-end home theater or fixed installation projectors include lens shift.
