Hello !
I have no idea because I don't know the LG projector.
However, it's a universal mount that seems to me to have quite a lot of possible settings, so, on the face of it, I'd say it should also fit the LG projector.
Be careful though: my Benq mounts upside down, so be sure your projector offers a 180 degree image inversion!
I wish you all the best for the holidays! :-)
