How to adjust if the project screen doesn't fit well

Shopping

I bought a project and hung it on the ceiling, but when I turned it on, the screen came out in a trapezoidal shape. How do I adjust this?

Or should I get as?

pu1. If you shoot from the front, it comes out in a rectangle, but if you shoot from the ceiling or the floor, it comes out in a trapezoidal shape. It's a vertical keystone function, but it's on the menu
