Using a ceiling as a screen

[Boon_Hong_Wong]

The ability to project on the ceiling is my primary requirement before I made the commitment to purchase this. The manufacturer has even assured me that their tripod will be able to tile 90 degree upward to ensure minimum distortion.

Unfortunately the tripod shipped to me look difference. But there is no problem with using the ceiling as the screen:

Manual keystone required

Hi, I understand that the given tripod cannot position the projector to be at 90 degree to the ceiling: [image] And the auto focus is unable to adjust the keystone properly, resulting in a distorted trapezium projection. Can provide an option for manual adjustment of the keystone so that we can correct the distortion?
