Buying projectors is like buying TVs, mobile phones, computers, and other products. Consumers need to understand the projector's products' related parameters and some purchase common sense so that they can choose a practical projector product according to their own needs. So what parameters should we pay attention to when buying a home projector, and how do we buy common sense? Take a look. 
The parameters that must be taken into account when selecting the projector include: lumens, resolution, and contrast. 
Luminance is what we usually call brightness. The higher the value is, the brighter it is. When the brightness reaches a certain height, the ambient brightness is no longer reduced when using the projector.
The resolution determines the fineness of the picture. As far as projection is concerned, 720p is the HD standard, and 1280x720 and 1280x800 are HD resolutions, while 1080P is called FullHD full HD. Pay attention to the use requirements when choosing.
Contrast ratio, the ratio of black and white, the greater the ratio, the more gradient levels from black to white, and the more colorful the color performance. Most LCD projectors have a nominal contrast ratio of about 400:1 (ANSI), while the DLP projector's nominal contrast can reach 1500:1 (full white/all black). Of course, the choice of contrast is also determined by the demand for use. If you only use the projector to display text and black and white pictures, then the projector with a contrast ratio of about 400:1 can be used to meet the needs of use, if it is used to demonstrate colorful photos and play videos. For animation, a high-contrast projector of 1000:1 or higher is selected.
In terms of purchasing common sense, it is mainly to understand more details, of which the light bulb is a very crucial one. Many high-quality projectors use Philips-made lamps. In addition, the dust is the biggest killer of the projector compared to the bulb damage, so the dustproof design of an excellent projector will also be in place.
Many companies nowadays will add a lot of additional functions to the projector, such as central control, laser pointer, Chinese menu, automatic keystone correction, high-definition interface, built-in speaker, network control, Blu-ray 3D, power off protection, AVMUTE, anti-theft lock protection, 12- Bit3D digital gamma correction, surface correction and various energy-saving modes, etc., users can choose according to actual needs.
Many consumers think that the higher the brightness of the projector is, the better. In fact, the brightness should match the screen size and the environment. If the brightness is too high or too low, it will hurt the eyes.
At the same time in the purchase, it should also pay attention to the projector surface should not be obvious signs of scratches, scratches, cracks, burrs, mold and other defects, the surface coating should not blistering, cracking, shedding. The symbols and signs on the product's nameplate and description should be correct, clear and firm.
