Brightness
Projecting in an environment with a lot of light would make the projection faded and weak, so it is essential to choose bright projectors with a lot of Lumens to ensure that the projection comes out good and excellent. The brightness is often measured in Lumen; however, 1 Lumen is approximately equal to the light produced by a lit candle.
It is advisable to settle for between 1000 – 1500 Lumens if needed in a dim environment and buy a projector of about 3000 Lumens if you would be using it in space that is well lit. This would ensure that the screen is seen. So, the brighter the projector, the better the readability and image output.
Resolution
The higher the resolution, the better the quality of the image the projector would produce. If you are projecting colors and animations, it would be recommended to settle for a projector that is higher than 800 × 600.
So, the higher the resolution, the better it is for the projector to produce an amazing viewing experience.
Throw Ratio
The Throw ratio is the projected image size based on how far the projector is from the stand. Several projectors are designed to have a certain foot that can g
et up to 15 feet. Also, some larger projectors can even get up to 30 feet.
Therefore, a short-throw projector does not need a lot of space or length between the projector and the wall. It can simply be placed closer to the object that you would be projecting to. However, if you have a lot of space between the projector and the screen, a long throw projector is recommended.
However, it would be good to note that short-throw projectors are usually more expensive and are not easy to come by.
Contrast
This is the difference between light and dark. The greater the difference, the greater the contrast. Therefore, it is recommended to buy a projector that comes with a wide contrast range; this would make it possible for users to adjust the image until the preferred image is gotten easily.
Screen Size
This is not the screen size on the projector but the size of the surface upon which the projector would be projected.
It is crucial to be sure of the size of the surface you intend to project on and the mounting distance between the projector and the surface. It is recommended that the measurement aligns with your projector.
Life Expectancy
Projectors come in two varieties; LED projectors and laser projection systems. LED projectors are usually weak because of their contrast ratio and the luminosity, but they boost a longer lifespan (about 20,000 hours) than the traditional projectors.
