Today we look at a topic that many potential buyers will projectors to make informed choices, while not relying on advertising slogans or tales seller, and real criteria, technical specifications and the knowledge of how to select the projector.An excursion into the world of lumens, and other pixel matrix is declared open.
Surely you've wondered how to choose the projector.I will assume that the information on this subject written by WHO and a small truck.I propose to make an easy and pleasant trip, to determine for themselves what is better - a projector or TV, and at the end to become an expert in this matter.
range of modern projectors capable to impress anyone who was first immersed in the study of this topic.Large, small, fixed or portable, with a bunch of features in the specification and frightening numbers in the price list.Lets you review and classify these objects, define their goals and needs, and after correction related to the budget for future purchases in our bottom line will be a few candidates.That is with them and will eventually have a conversation "heart to heart."
How to choose a projector and what to look for?
item № 1. First of all, you need to pay attention to where and how you plan to use the projector.Depending on this, several types of looms:
- home (home theater);
- work (presentations and conferences);
- for public events (shows, concerts, events).
is the starting point, which is based on further consideration of the candidates.Design features and specifications for each item will be markedly different from each other.
item № 2. next aspect greatly affect the quality mapping materials on the big screen.This is the brightness of the projector, and to be precise in the wording - of the power of the light flux, a projector can emit.The units, which measure the luminosity of the projector, called or ANSI lumens.
- small room with full dimming, this value can vary from 600 to 800 units.
- to work in a suit with a partial lighting apparatus capable of delivering "on the mountain" brightness from 1000 to 1800 units.
- If you have to work at all without blackout in daylight - it is better to opt for models from 2000 to 3000 units.
- from 3,000 units - for premises up to 100 square meterswith bright daylight.
- 5000 and more - halls for 150-200 people with bright light.
- Projectors aperture of 10 000 or more - it's professional projectors, destined for the big concert halls and stadiums.
item №3.The resolution of the projector. This value characterizes the ability of the projector to display on the screen a certain number of dots (pixels) per unit area.The higher the resolution of the projector - the smaller the grain, the more detailed the picture is, and the better the picture will look on the big screen.But do not get involved in astronomical figures resolution: the image quality is very dependent on the resolution of the signal, which is supplied to the projector for display.The standard resolution of 600x800 pixels the projector will display almost no loss of material in DVD quality.To display high-definition images look better on a model with a resolution of 1280 by 800, and even better on Full HD - 1920 to 1080 (when it comes to home theater - this is the only acceptable solution).
item №4.Contrast the projector. This parameter is responsible for the "depth of color."In fact, this projector's ability to display most vividly black and white color when projecting images on a large screen."The golden mean" - the weighted average number between the maximum and minimum values of several models.By and large, the difference between 800: 1 and 1000: 1 is almost imperceptible.
All other parameters are very similar and the projector can be only slightly different from each other.Before you choose a projector final - guided by their needs: the presence of Wi-Fi, «a picture-in-picture" freeze-frame and other "bells and whistles" are not important.Make sure you have the main connectors that are responsible for the input signal (desirable input HDMI), pay attention to the life of the lamp and the cost of buying a spare to replace it.This, in principle, would be enough to understand how to choose poektor and what you chirps hitroglazy Sales.
