Projectors are used to display images from a computer or external storage on the wall or a projection screen. The projector is usually part of the equipment of most meeting rooms, many movie rooms, home cinemas and living rooms. How to choose a projector? Read more to find advice on what to look for.
Projectors bring a number of advantages that make them useful in both the professional and private sectors. Take a look at the most important advantages that office and home projectors provide.
A projector allows you to project images on projector screens that are unmatched in size by any television.
Modern projectors also boast fine resolution (you can choose from Full HD projectors to 4K projectors), which guarantees sharp visuals.
It is a portable device that can be mounted on the ceiling or simply placed on a table.
Models labelled as mini projectors, also known as portable projectors, in particular, encourage you to bring them to your cottage or your friends' flat.
The advantage of projectors is also their wide connectivity - HDMI, USB, VGA, DisplayPort, nothing is missing.
This high-quality projector can handle presentations, photo albums, home videos, as well as movies and graphically demanding games.
Projectors and Their Key Parameters
Whether you are choosing a home, office, movie or mini projector (portable projector), you should focus on the following important features and parameters.
What Resolution Should Your Projector Offer?
Choose the projector resolution according to the distance and size of the screen, as well as the type of content being displayed. In general, higher resolution projectors are more useful for projecting movies or small graphics onto large projector screens.
An HD Ready Projector is suitable for projecting graphically simpler content on smaller projector screens.
Full HD projectors are among the most popular projectors ever. They offer a high-quality image with sharp details.
A 4K projector will be appreciated by demanding film enthusiasts who seek dynamic images of the highest quality.
Projector - Minimum and Maximum Projection Distance
Minimum and maximum projection distances indicate the ideal distance between the projector and the projector screen at which the projector performs best in terms of image quality. As the distance between the projector and the screen increases, the size of the projected image increases.
Projection distance
2 m
3 m
4 m
5 m
Diagonal
1.1-1.6 m
1.6-2.4 m
2-3.2 m
2.5-4 m
Projector and Luminosity
Luminosity indicates how bright the image that the projector produces is. Higher lumens (lm) values ensure that the projected image is legible even in very bright environments. We offer projectors with lumens ranging from a few hundred to several thousand lumens.
Projector – Projection Technology
Choose an outdoor projector, office projector or home projector based on the technology it uses to project images. DLP and LCD technologies are among the most widely used.
DLP projectors offer excellent contrast and shadow details. Their downside is that rainbow effects can appear behind fast-moving objects on the projector screen.
LCD projectors stand out in terms of their quality of colour reproduction. They do not suffer from rainbow effects and tend to be quieter. However, they have slightly poorer black reproduction and are more maintenance intensive.
Projector – Light Source
Projection technologies are closely related to the light source used in the projector.
LED projectors are generally smaller and score with their low consumption and noise levels. The disadvantage is lower luminous intensity.
Laser projectors use a blue laser as a light source to display more colours.
i
Lamp projectors using a halogen lamp as a light source are also popular among projector users. They require a larger projector design and have a higher power consumption than LED.
Mini Projectors, Portable Projectors – Home Cinema in Your Pocket
Mini projectors, also known as portable projectors, are very compact options for your computer, laptop or phone. Don't let the tiny design fool you - a mini data projector is not a toy. It's perfect for any party, game night or team meeting.
Home Cinema Projectors
Home cinema projectors bring the best for movie and TV lovers. The emphasis here is on superior picture quality, which is crucial for a full movie experience. High resolution (look for up to 4K projectors), premium luminance and superior colour rendering are therefore a matter of course.
Films are shot in a widescreen format, so choose a projector with a 16:9 or 21:9 aspect ratio.
Office Projector
Office projectors are usually used in meetings, conferences and rooms where data needs to be presented on a large projector screen for all attendees to see. A data projector, as this type of projector, is also called, needs to be easy to use and reliable first and foremost.
i
Although a data projector is most often associated with displaying spreadsheets and other statics, that doesn't mean it can't handle promotional or instructional videos.
3D projectors add another dimension to screening, literally. Get ready for a unique three-dimensional spectacle with maximum image quality that will immerse you.
When Do Android Projectors Come in Handy?
Android projectors are equipped with a feature-packed operating system that includes apps like Netflix, YouTube, Amazon Prime and many more. Don't have an external drive, a laptop, or a phone which contains your favourite movies? That's not a problem anymore with an Android projector.
Interactive projectors allow you to interfere with the projected image without modifying it on the computer. It uses a special electronic pen to draw or write notes on the image.
Vizualisers
Visualisers can capture the graphic background in digital form and transfer it to a computer or projector screen. A visualizer is a great tool for lectures or presentations.

Projectors are excellent presentation tools as well as perfect home cinema devices. They can be easily connected to DVD players and computers, so you can sit back, munch popcorn, and enjoy great cinematic experiences in the comfort of your own home.
Projectors typically have many input signal options, featuring composite, S-Video, VGA or HDMI. You can project on plain white walls, but to get the best performance, choose from the range of professional projection screens available. Depending on the way in which they process the internal video signal, projectors are either LCD or DLP. Although these technologies are different, and LCD projectors used to be considered better for projecting data from computers while DLP models were ideal for screening films, today both technologies are practically equivalent.
LCD Projectors The light source in LCD projectors passes through three primary colour filters. Each then passes into one of three LCD panels through a permeable layer. Finally, all three colours are combined again and projected through an optical device onto a screen, where they are displayed as a complete picture. These devices are both lightweight and easy to maintain.
DLP Projectors DLP projectors work with DMD chips and use a large number of microscopic mirrors, with each mirror representing one pixel. The image is again broken down into the three primary colours (red, blue, green) and then passes through the micro mirrors and lens before being projected onto a screen.
