Many netizens will feel that as their projectors are used longer and longer, the brightness of the projectors will gradually dim, some may be normal, and some netizens ’projectors have been used for more than a year. A similar situation will occur, what is the reason? Is there any way to solve it? Today I will tell you why the projector screen is dark and some solutions.
Reason one: The pollution of the optical path system is mainly dust and oil stains, which will affect the image quality after a long time.
Solution: scrub the optical path and adjust the optical path.
Reason two: the brightness of the bulb itself may be attenuated
Solution: The life of the light bulb is relatively low, and the main performance is the decrease in brightness. The general life span is only 2000 to 3000 hours, and it will be much better after replacing the lamp.
Reason three: power limitation
Solution: This is the relationship between the projector's own hardware, and we can try to make the projection in the dark room by drawing the curtains.
Reason four: the projector is not debugged
Solution: There is brightness adjustment in the remote control, and the general default state is the maximum brightness. During the adjustment, "Menu" and "Image" are added. There are adjustment items such as resolution, contrast and brightness.
The above is the solution to the projection screen is too dark! In the future, you can solve such small problems at home!
