I'm looking to get the Wanbo x1 too. Saw and took this table from Taobao seller. English wording from Google translate.

Just want to ask, x1 only support up and down keystone correction and x1 pro(android) supports up,down,left,right keystone correction. Is this correct? If i get x1, does that mean i have to place the projector right in the middle and cannot place it at the side?

Noob here, 1st time buying projector for bedroom use.

Just received my wanbo x1 too. The image quality amaze me. pairing it with mi stick is just awesome.

1 question on the wanbo x1. Is there a way to adjust how big the video projected on the wall? See pic below, over the projected wall after i placed it too far. If Wanbo x1 doesnt have this function, what is this function call in projector world, would love to know in case i get another projector in the future. Thanks.
