If you are considering purchasing a new projector for your classroom, conference room or home theater, the image you project onto the screen should leave a great impression on your audience. Researching different projectors is often confusing due to the multitude of acronyms and technology terms. Our product guide will help you answer common questions about terminology, features, and other important considerations to keep in mind when choosing a projector.
How to Choose the Best Projector for Your Home?
Contrast ratio
Contrast ratio is the difference in brightness between a bright image and a dark image, explained by a number. If you take the brightest white and the darkest black on a screen and compare the brightness, that will give you the projection contrast. For example, a projection contrast of 1,000:1 means that the brightest white is 1,000 times brighter than the darkest black.
Resolution
Resolution is the number of dots or pixels used to display an image. Higher resolutions mean that more pixels are used to create the image, resulting in a sharper, clearer image. High resolution is important for projecting detailed charts and graphs, text, and high-definition video. Resolution is indicated by a combination of numbers such as 1920 x 1200. This indicates that there are 1,920 dots horizontally across the screen and 1,200 lines of dots vertically, which equals 2,304,000 total dots that make up the image you see on the screen.
Ease of use
For hassle-free projection, you may want to look for certain features that will facilitate quick setup, so you can get projecting right away.
HDMI - instant, digital and easy connection to high definition equipment, allowing you to transmit digital audio and video over the same cable.
Wireless connection capability – Allows you to project content wirelessly and is available for many types of devices.
Vertical and horizontal keystone correction – allows you to quickly align a crooked image on a screen, which is essential during a hasty installation.
Instant on and off : you don't need to wait longer for a projector to warm up or cool down.
Projection technology
There are two technologies used in most projectors: 1-chip DLP and 3-chip 3LCD.
Wireless connections and wired projection
From your computer, there are several ways to project content without using cables.
Choose a wireless projector INCLUDED . This means that the equipment includes wireless projection at the factory (802.11 b/g/n). Once you connect the LAN module included in the projector, it is enabled to project wirelessly.
Choose a wireless projector OPTIONAL and purchase the necessary wireless LAN module separately to enable the wireless function. Simply connect the purchased LAN module to the projector and it will be enabled to project wirelessly.
Interactivity
Epson interactive projectors make any table or wall interactive. The projector and pen combination gives you interactive features in one package, without the limitations or added costs of an interactive whiteboard. Interactive projectors are short or ultra short throw, allowing you to project without glare or shadows.
Shooting distance, positioning and image adjustment
The position of the projector and the size of the image will depend on the configuration of the room. Therefore, you will need to consider the projection distance and the projector's features when deciding where to place the equipment. A projector that helps you easily control and adjust the image makes it an easy projector to use.

The distance or throw of a projector (Throw Distance) is the distance between the projector and the projected image.
The distance or shot is:
Long range: allows large images to be generated at a certain distance. This type of range is common when using projectors installed on the ceiling of a large room.
Short focal length: allows large images to be generated at a short distance, reducing shadows and reflections in the image. This type of projection is common when using projectors that must be installed on the wall or ceiling, close to the wall. the image is projected. Short throw projection generally refers to a distance between the projector and the screen of between 90 cm and 2 meters.
Ultra short focal length: Allowing to almost completely eliminate shadows and reflections from the image, this type of projection is viewed from projectors installed on the wall, or on a table on which it is projected downwards. Ultra short throw projection refers to a distance between the projector and the screen of between 0 and 1 m.
Monitoring and control
Epson's monitoring and control feature makes maintenance convenient and easy. The benefits of using this feature include remote monitoring and management of the Epson projector network, saving time and money.
