The many specifications of a data projector

Posted by AxelPrice on June 7th, 2014

Getting the right projector for one’s use is of crucial importance. Business events, trade show, training sessions, classroom lectures, corporate presentations and not to miss out the fantastic movie experiences, all rest upon quality digital projectors. Generally, there are two categories- one being the data projector and the other, video. While the former is equipped to display still images like presentations, photographs, PDF files, spreadsheets and the like, video projectors are the best options for moving images besides the still ones too without forsaking on the quality bit. You can take your pick from the lot like Nec projectors, Acer projectors and several other leading companies that store multifunctional devices.

When selecting a data projector, always remember that there are variegated tasks to be accomplished with the help of that. Two major types are found in the market, namely LCD (Liquid Crystal Display) and DLP (Digital Light Projection). Using LCD projectors, the video signals are reflected off of many tiny mirrors that improves clarity and resolution. Besides, they are easy on the pocket too. On the other hand, DLP projectors that are known for their amazing image quality and you find movie theatres resorting to these, use ‘micro mirrors’ when displaying images. The significant features that you should check include resolution, brightness, size, aspect, lamp types and weight. If you care to see that these things are intact, you can get your work done in the best possible way.

When choosing Nec projectors or Sony projectors, ensure that the specifications do justice to the exact requirements. Have a look at them:

-Brightness: Measured in ANSI lumens that lies within a range of 1000 and 1500 lumens, brightness of the projectors are optimum. Whether you place it in a simple office or during your boardroom presentations, the effect is more when room lights are dimmed. You can select a more powerful device that lies between 2000 to 3000 lumens when the requirement is a brightly lit venue.

-Resolution: This term actually describes the pixel numbers the projector is capable of projecting on screen. Higher the resolution, the more sharpness an image gains on the screen. Majority of these projectors belong to either of the two categories- SVGA (800x600) and XGA (1024x768). It is recommended that projector resolution must always match the source resolution. Regardless of your source being a computer, a game box, a DVD or a Blu-ray player, determining the projector resolution is important.

-Contrast Ratio: A projector’s contrast ratio describes the ability to block out the projection lamp light. This translates in the depth of the black parts of any image that is projected. This factor is mostly considered when seeking an image of certain sharpness.

-Projection screens: Depending on how your projector is positioned before the screen, you need to select your projection screen.  The front projection one is all about positioning of the projector before the screen and requires only a normal screen. With rear projection ones, there is a requirement of specialized screen type.

If you can take the above-mentioned factors in mind, your coveted data projector is only a stone’s throw away from you.
