The projector hums when I display a 4K or 1080p 60 Hz signal with the 4K Enhancement setting enabled. What should I do?
Try displaying a 24 Hz signal instead. The humming may not be as loud.
When the 4K Enhancement setting is enabled, the projector's internal 4Ke device operates at a high speed to display an image in fine detail. It is normal for the projector to hum slightly when the 4Ke device is operating.
Note: The 4K Enhancement setting cannot be disabled when projecting a 4K signal.
