I have installed the projector upside down in my basement, if you can see the image below, video is about 3 inches below where needs to be from the top part of the screen. I am kinda stuck on how to fix the issue, being the project is upside down and stuck to the ceiling makes it little bit hard.
Hi @menis4u, you can adjust the wheels on both sides of the projector or use the keystone correction function, it will allow you to manually adjust the lens of the projector in order to project an angle that is higher or lower.
If you need more assistance, you can email us at support@vava.com to further assist you.
Thank you and have a great day!
