Points to note when purchasing a projector:
The color of LCD is relatively poor, and it is mostly used for projectors with a hundred yuan level.
The color accuracy of 3LCD is good, but the response speed is relatively slow.
DLP is better than LCD, with good color reproduction, long service life, fast response speed, but the contrast is still insufficient, and it is mostly used by mainstream smart projectors.
3DLP is only used in movie theaters, and the cost is extremely high, and it can achieve 4k viewing effects.
LOS chips are usually used in mid-to-high-end machines, with good reproduction, contrast, and excellent performance in dark details, but the service life is relatively short.
When we usually watch movies, we often see a number in the upper right corner, such as 480p, 720p, 1080p, which is the resolution. The higher the resolution, the better the picture effect. There are standard resolutions and compatible resolutions. The standard resolution is the "true" resolution that is projected. If the budget is sufficient, it is recommended to choose 1080p.
There are four types of light sources, the most commonly used are LED light sources and high-pressure pump bulb light sources. The LED light source is cheap and has a long service life. It can support more than 2w hours, but the brightness is not high enough. The high-pressure mercury light source has extremely high brightness and can be used during the day, but it has serious heat and has a short service life. It needs to be replaced after 3000 hours and has a lot of consumables. So smart projectors are mostly LED light sources.
XPR technology can make pixels move at high speed to produce displacement, which improves image quality to a certain extent.
Wireless projection function: You can project the mobile phone screen onto the screen.
Bluetooth connection function: It is possible to play music or transfer photos after Bluetooth connection.
Voice control: I think this function is very convenient, like grandparents are not familiar with using the remote control, the voice can call up the corresponding station, it is very convenient.
Motion compensation: mainly to enhance the smoothness of the picture, especially when watching some sports pictures, the lack of this function will cause the picture delay.
HDR decoding function: This function can make the existing picture more refined, such as brightening the picture in the dark.
Keystone correction, side projection: There are automatic and manual points, it is recommended to choose automatic, put down the projector can automatically correct the picture.
