After reading the detailed parameter introduction of many projectors, I didn't see one with the refresh rate written in the parameters. I am wondering why does the projector seller not emphasize the projector refresh rate? Is projector refresh rate important or not? Why?

The projector refresh rate is an important indicator , especially the refresh frequency under 3D display. For example, the Panasonic AE8000, the last generation of Panasonic, has a 480Hz refresh rate . The current Epson 3LCD refresh rate should also be 480Hz. This not only ensures the smoothness of the picture, but also the brightness in 3D can be increased by about 50% compared to the 240Hz refresh rate and more than the early projector refresh rate 120Hz Many, as long as it is a projector with 3D function, the projector refresh rate will not be less than 120Hz.
In general, the movies we watch more than Blu-ray 3D are only 24 or 30Hz, a small part of 60Hz, 120Hz frame rate is less, projector refresh rate will be doubled to the refresh rate of the display.

Each tool has its application scenario. The projector is suitable for multi-person meetings and theaters.
You will find that the number of viewers + viewing distance determines the size of the display area.
What about high frame rates?
The high refresh rate can be said to be the icing on the cake for the game, high refresh rate will improve the smoothness of the movement of the viewing angle, the movement of the characters is more natural and so on.
But for TV and projectors, refresh rate is a useless thing that increases the cost. The standard projector refresh rate does not affect the viewing experience, and increasing the frame rate will greatly increase the cost, and almost no content is prepared for high frame rate (you heard Have you ever passed a 120hz TV channel or a movie)?
In comparison with projector refresh rate, improving the resolution and display effect will allow consumers to pay. Besides the projector, its biggest advantage is the low price for a large display area. At the same time, the heat dissipation of high projector refresh rate is not good (school projections often shut down automatically due to excessive heat caused by too much dust), so the main projector is still theater and meeting ppt. The difference in the display principles of the projector, TV, and monitor may also be the reason why there is no high projector refresh rate
I just answer from the consumer level of the refresh rate. Before buying a projector, you must think about what to use. It is really not recommended to use projectors when playing games.
