The entertainment world continues to attract more people daily. Whether in the living room in the office or even in our vehicles. As such, visual technologies like projectors have been developed over time to meet the needs of the market in adding usability at all levels in addition to durability as well as quality viewing.
The catch with projector is that they offer you a great cinematic experience where you get quality images with high resolution and, most importantly, a huge viewership coupled with a wide array of colors, just like the TVs. As such, here is all you should know about projectors.

All You Should Know About Projector
What is a Projector?
A projector is a device that is used to project an image as well as a video onto a projection screen or a wall. Unlike the TVs, It is capable of projecting a large area and, as such suitable for large audiences like theaters, concerts, schools/colleges as well as home cinemas for real life-like experience.
Furthermore, the projectors may project images as well as videos from a phone as well as from computers. By mounting the projectors on a ceiling or a wall with regard to type and condition, the image is then projected to a wall or a set screen.

Understanding Projector Resolutions
The clarity of the image being projected by a projected is the resolution of the projector. It is basically explained in terms of the number of pixels on the horizontal multiplied by the number of vertical pixels. This means that the more the pixels, the greater the quality of the images projected. As such, resolution forms one of the basic crucial properties that you must consider before making any projector purchase.
On the other hand, pixels form the picture elements whose joining together to make up the image. The more the number of pixels projected onto a screen, the sharper the image projected in comparison to a projector with similar with lesser pixels. As such, since the resolution refers to the measure of the pixels projected, the division and grouping of the projector’s resolution happen by the number of pixels in a particular projector.
As such, there are various standard formats for grouping projectors according to their pixels. For instance, XGA, which features (1024 x 768 pixels), meaning that 1024 pixels arranged horizontally and 768 arranged vertically. Additionally, there are WXGA projectors with (1280 x 800 pixels), meaning that 1280 pixels arranged horizontally and 800 pixels arranged vertically. Furthermore, HD projectors feature a resolution of (1920 x 1080 pixels) meaning that 1920 pixels arranged horizontally and 1080 pixels arranged vertically. And at the top of the list are 4K projectors that have a resolution of (3840x 2160 resolution) meaning that 3840 pixels arranged horizontally and 2160 pixels arranged vertically.
Additionally, a projectors’ native resolution refers to the number of pixels a projection chip contains, be it the DLP or LCD chip. This forms the real resolution of the picture element in the projector. A cheaper one has lower native resolutions, while expensive ones have high resolutions.
How to prevent your projector from getting overheat
There are many people who have complained of heating up of their projectors when in use. This has led to disappointments thinking their products were substandard. To avoid overheating, a few things must be observed.
Cleaning the air filter
Fans in a projector are responsible for removing warm air and drawing in cool air. The air is filtered by filters that avoid dust and debris from getting into the projector. Clogging of the filters with dust and debris causes the failure of the fan. As such regular cleaning of the filters prevents the heating up of the projector.
Placement of the projector
Many people do not know the reason for the ventilations present in a projector, and many think they are just for elegance as well as design. However, these form the air vents where fans and blow and draw air from when it is in use. Blocking of the vents forms the immediate cause for heating up of the projector especially when being used on a table and placing staff like papers and books
The temperature of the room
Many of the projectors in the market presently rely on airflow in effecting cooling on the projector. However, if there is no reasonable air temperature difference in a room causes it to heat up since there are no heat transfers. There must be a temperature difference between the projector’s temperature and the surrounding. As such, operating the projector in hot rooms immediately causes it to heat up easily.
The manner you use your projector determines whether it will heat up or not. If not in use, shut off the projector rather than leaving it to run for long periods. Additionally, if you know, you will use it for long hours, during break time, or even mealtimes, it is expedient to shut it off for it to cool. This also acts to extend the lifespan of the projector.
The use of projector continues to increase in the world currently. Especially due to improved technology that has allowed for high resolutions that have led to quality as well as clear image projection. In the boom of the projectors, they have found great applications in our home theaters as well as in many other large gatherings.
