Optoma UHD50 Owner - Bottom Lines Slope Upwarsd to the Right

Has anyone ever experienced this before with their Optoma UHD50 before? I have attached an image that shows what I am talking about. The bottom line slopes upwards to the right while all other lines are relatively straight/level. I've gotten pretty used to it now when I watch either TV shows or movies (on movies the bottom black bar slopes up to the right a bit as a result of this) but I was wondering if anyone else has experienced this before and corrected it. This is also my 2nd model after returning the 1st one so I don't think it's related to the unit. Thank you for any and all help!

Probably your screen.

Or the pj isn’t mounted perfectly straight.

It's a geometry issue with the projector and screen. Its close enough so I wouldn't worry about it. The screen or wall your projecting on may not be flat. Try pulling out the lower left corner of the screen out a 1/2 inch and see what happens. The projector may be slightly too far to the right, rotate the projector to move the image to the right a inch or so and see if it fixes it. IF you have lens shift correct it back to center with it, if not you would have to move the whole projector to the left.

EDIT: of course the UHD50 doesn't have horizontal lens shift so correcting this could be a big hassle.
