[Whether the high-brightness projector should be equipped with a low-gain screen] Projection screen

For a long time, people have the opinion that low-brightness projectors should be equipped with high-gain screens, and high-brightness projectors should be equipped with low-gain screens. Although the opinions in the first half are good, the opinions in the second half are open for discussion.

In fact, it is difficult for a high-brightness projector to maintain high brightness for a long time. If a 3000 lumens projector is used frequently, it may only have 2000 lumens brightness after one or two months. It may drop to 1500 lumens later. In this case, if you are equipped with a screen with a gain of 2 times or less, you will feel that the effect is getting worse and worse. If you are using a negative gain screen, you may wish to close the screen and hit the white wall directly. never mind.

Actually, the brightness of the projector is adjustable. If it is equipped with a high-gain screen, the brightness of the projector can be adjusted down appropriately at the initial stage. After the lamp is attenuated to a certain level, the brightness will be adjusted back to maintain a long-term stability. At the same time, it prolongs the service life of the bulb, and solves the old problem of fast decay of the projector bulb to a certain extent.
