can use the projector's Corner Wall setting to adjust the shape of
an image projected on a surface with right angles, such as a
rectangular pillar or the corner of a room.
Note: For the
best results, project from the front of the screen onto a
right-angled surface. The image may not be evenly focused
throughout even after performing the steps here. If you see a 4K
Enhancement message, select Yes
to disable the 4K Enhancement feature.
