Remote Control Effective Range - Asus ProArt A1 E-Manual

Remote control effective range

Remote sensors are located on the top and front of your LED
projector. The remote control must be held at an angle of ±30
degrees perpendicular to the projector's remote control to function
correctly. The distance between the remote control and the sensor
should not exceed 8 meters (about 26 feet).
NOTE: Ensure that there are no obstacles between the remote control
and the remote sensor on your LED projector.
