The projection redness of the projector is mostly caused by improper adjustment or the hardware of the device with a carrying key, which is explained separately below.

1.Adjust the issue.

1) Adjust the color temperature.

Projectors can sometimes have color deviations due to color temperature. We can enter the system settings through the remote control of the projector, and there is a color temperature option to set inside, which can be adjusted one by one to see which color temperature works best. If not, you can set it up yourself through the custom mode in the system.

2) Adjust the contrast of the projector.

2) There is a problem with the optical wheel.

The optical wheel of the projector is also a part that often causes problems, which will also lead to the phenomenon of projection redness, if the small problem can be repaired, if the big problem is only to replace the entire optical wheel or replace the projector.

In short, the phenomenon of projector projection redness is caused by a variety of reasons, which can be done by adjusting and adjusting. If the hardware problem is large, it is recommended that you send it to a professional maintenance organization for repair.
