Correction of the edges

I received my PPM today. Absolutely thrilled and happy with the device overall though faced some glitches.

The most irritating glitch is the corner correction. The corners are not even and I see a trapezium shaped display on projection. How can I fix this? Could someone please help? I am on the latest 27 release.


Have you tried image settings auto calibration first?

Are you sure you positioned the projector perfectly aligned to your wall? You can also try turning off automatic keystone correction if you want to position the projector manually.

How do I turn off automatic keystone and manually adjust? I did position the projector perpendicularly to the wall.

No, could you please send me the instructions. Thanks in advance.
