How to Fix Poor Auto Keystone Correction on Poseidon E100?

Auto keystone correction relies on sensor-based detection, which may become less accurate in cases of steep projection angles or complex environments.

We recommend:

• Adjusting the projector placement to minimize the tilt angle as much as possible
• Using manual keystone correction or four-point correction for finer adjustments
• Ensuring the projection surface is flat and free of obstructions
