video projector image cut?

I have my video projector, and I configured the image that I projected on my screen is cut on the right side, so I did that 3 / 4 of the image. if I wanted to know how to put my video projector eco-mode (for mitigating the sound of the ventilation because it's really hard) then it would be awesome. Thanks for the help

Anyone there please help

What is the make/model of your projector? Was it working fine before or it was showing cut images previously itself? If i were you i would have taken it to the manufacturer & replaced it.
