Why is the keystone correction of Cosmos 4K SE inaccurate when projecting sideways?

Thank you for your support of our products.

 

The keystone correction standard for the Cosmos 4K SE when projecting from the side is: at a projection distance of 2 meters, the height difference of the edges on both sides should be less than 2%. 

 

Insider information:

Projection distance is 2 meters:

20 degrees: height difference <15mm, 30 degrees: height difference <20mm.

Projection distance is 3 meters:

20 degrees: height difference <25mm, 30 degrees: height difference <30mm.

 

We apologize for any inconvenience this may cause.

 

If the above solutions cannot solve your issue, please contact Nebula Customer Support at support@seenebula.com for further assistance.
