Hello,
I bought a few days this projector from  official store, and I soon realized that there are white spots in the dark images. One of these spots,the lower right, is out of the projection rectangle.
I would like to know if my projector is defective or something else.
I attach photos with the defect ,thank those who will help me
Best regards

Turn the projector 180 degrees (on its 'head') and see if spots follow.  Let us know!!!

Hello refdaddy,
i did the test as you said, and the spots follow the rotation. What does this mean that the projector is defective?
I look for your answer thanks for the help

It's the dust that causes these white dots I've just had it right on my projector it's necessary to open the projector and clean the optic through the air

Hi Marian909,
from what I understand you had the same problem, so I ask you if it is complicated to open the projector to remove dust.
Thanks for your help.
