Principles for choosing to buy a projector

With many different categories, including the purpose of use (presentation, movie, gaming), technology (LCD, DLP, LCOS), . is what current projector technology brings. So where is the projector model suitable for your use?

Projectors are becoming more and more popular for users.

Here are the helpful advice you can take to choose an appropriate projector.

The type of image you plan to show

There are basically 4 types of images you can show on a projector: data, videos, images and games. Any projector can display any type of image, but it is important to understand that any projector is capable of handling it specifically. Therefore, you will have to choose a projector that meets your needs.

A data projector supports well presentations, spreadsheets and PDF files, while a movie projector is capable of handling full-screen motion videos.

Resolution of the machine

Note that viewing the projector's resolution information (the number of physical pixels on the projector's display screen) is appropriate for your regular use.

For a typical PowerPoint presentation, the quality of SVGA display (800 x 600) is considered the best. 1080p is the current high-definition quality best suited for video presentation from a Blu-ray player or other home entertainment device. However, the quality of the presentation depends on the cable you use, if the VGA or DVI cable is only available at a lower resolution quality.

In addition, some videos and games require widescreen elements. Now both for data projectors, wide screen resolution has become popular.

Brightness of the projector

It should be noted that the 2000 lumen ratio with 2200 lumens is a significant difference. There is not a better and brighter brightness level than ever. For a home theater projector, which you plan to use in a dark room, 1000 to 1200 lumens of brightness provide a large, bright image while using a high brightness 2000 projector. Lumen can make your eyes uncomfortable when viewed by being too glare.

On the other hand, for a mobile data projector, you might expect to use where there is enough light, the brightness of 2000-3000 lumen is suitable for you.

The affected projector brightness should be chosen depending on the projection area.

The noteworthy point is that the best level of brightness depends on the amount of ambient light, the size of the image and even the quality of the screen you are using.

Contrast ratio of the machine

Contrast ratio is the ratio of the brightness of the brightest area to the darkest one output projector. All other things are equal, a higher contrast ratio indicates that it is more vibrant, eye-catching colors and more expressive in dark areas on the screen. However, because there are other factors involved, the contrast ratio does not give you special results.

Connection slot

Most projectors provide a minimum of analog (SVGA) connections to computers as well as video devices. For video sources, the high-end option is HDMI connectivity, but to get this quality, you need an HDMI cable attached to that digital device, while one is connected to DVI to connect to the projector.

The technology you need to care about

Currently, the projector is based on 4 imaging technologies: DLP , LCD, LCOS and Laser Raster. You should not be confused about the Laser Raster as a laser emitting projector, in fact it uses a laser as a light source for imaging technology, like a DLP or LCOS chip.

Most DLP projectors are cheap and some pico projectors are based on LCOS. They often have a rainbow effect, with light areas on the screen divided into small rainbow shapes when the user changes the direction of seeing or moving something on the screen, which can be annoying for you.

LCD projectors do not encounter this problem but tend to be bigger and heavier than an equivalent projector. Currently, the LCOS projection standard is most trusted because it provides the best quality images, but it is also more expensive. There is currently no conclusion about the capabilities of the new Laser Raster technology.

Audio and 3D support

Not all projectors include audio playback because it is sometimes useless. If you need audio for presentations or to watch videos, buy a built-in audio output connector.

Currently 3D projectors are being developed by leading manufacturers, especially support for 3D games or movies.

However, there are not many 3D programs available and its price is quite expensive, so owning a 3D projector is not necessary.

3D content is now getting richer, which is why 3D projectors are also interested.

Slideshow in a small room

Finally, take note of the distance that the projector supports. High-end projectors are capable of projecting large images onto the screen even though it is located quite close to the screen, meaning it will be suitable for tight spaces, allowing you to view the content right away. my small room.

There is no common definition, but often a projector can project an image about 2 meters wide at a distance of 4-5 meters, while with this width the shortest projection distance that a projector This support is about 1-2 meters only.
