How to choose your favorite projector?

Projectors are widely used in homes, offices, schools and entertainment places, according to the different work mode, CRT, LCD, DLP and other different types. How to choose a reasonable price, function applicable household projector?

First, understand the use of projector

Users should be familiar with the use of projectors before choosing to buy them. Projector is divided into mesa forward projection, ceiling condole top forward projection, mesa reverse projection, condole top reverse projection, back cast an integrated box type. Forward projection means that the projector is on the same side of the audience; Backside projection is the method that the projector and the audience can choose the backside mirror refraction at both ends of the screen, if the space is small. If you need to use fixed installation, you can choose the ceiling, but must pay attention to dust and heat dissipation. Therefore, according to the use of the environment, determine the purchase type of the machine, is the first step in procurement.

Two, brightness and contrast should be moderate

Brightness is an important index to measure the performance of projector. Brightness is the amount of light a projector sends to the screen. High brightness makes a projector project a clear, bright image, but higher brightness is more expensive. The projector of high brightness is used in small environment very dazzling, can make eye fatigue, watch for a long time can make eye redness appears the circumstance such as eye disease even. Because this differs according to sitting room area specific, the household projector brightness that chooses is in commonly 500 to 1000 lumens between. Either too high or too low is not suitable for use in low lighting environments.

Three, choose the appropriate resolution of the projector

Projectors and digital cameras, digital cameras, evaluate its picture quality are the standard resolution. Note that the higher the resolution, the more expensive it is. There is also a compatible resolution, compatible resolution is a step higher than its physical resolution. As with DC and DV, the higher the resolution, the sharper the image and the higher the price. Although the effect of SVGA has been able to meet the needs of families, but in the long run, if economic conditions allow, it is best to buy the physical resolution of XGA standard projector, it displays clearer, bright.

Four, pay attention to the projection distance

For home users, living area is very limited, and the installation of the distance between the projector to the screen is not too big, so for the household environment of space is narrow, the projection distance to be one of the important conditions of the projector, users should compare different projectors under the same projection diagonal dimension of the projection distance, rather than a specification sheet on the project "the shortest distance".

Five. Consumables and after-sales service

To projector character, the bulb is its only consumable material, its life concerns the use cost of projector directly, must ask clear bulb life and change cost when buying so. More commonly used projector light source UHE and UHP two kinds, the former because of cheap, but not as long as THE life of UHP, mainly used in mid-range projector; UHP, on the other hand, has a service life of more than 4,000 hours and little brightness attenuation, but is also more expensive. Accordingly, should choose appropriate projector according to ability when choosing. The bulb that different brand projector uses cannot be interchanged commonly, because this buys projector, the projector that should choose to buy well-known brand should be chosen, the after-sale service that can enjoy a businessman so. At the same time after the purchase should be timely signed with the business after sale service contract or get warranty certificate in order to avoid the use of projector worries.
