FAQs
Browse all related FAQsCan I configure different sound modes based on my preferences?

You can choose from the following sound modes which are suited for different types of content. Please follow the instructions below to change the sound mode in the OSD menu: Audio > Sound Mode selection
Does the projector support Bluetooth or Wi-Fi speakers?
No, the projector does not have the capability to transmit audio via Bluetooth or Wi-Fi. We recommend connecting your speaker directly to your playback device or connecting the projector to an audio system via ARC/eARC for improved audio quality and to avoid latency issues associated with wireless transmission.
Do I need to replace the LED lamp of the projector?
There is no need to replace it during the normal usage lifetime of the projector. Because the projector uses an LED light source instead of a lamp, it can last for about 20,000~30,000 hours so there is no need to change it during the normal usage lifetime of the projector. If you want to change the lamp, please notice that LED replacement is not user-serviceable, please contact the service center to replace it.
Can I use the projector to watch the movie?
Yes, you can absolutely use any projector for movie, TV watching and any big-screen entertainment needs, and we also recommend dedicated home cinema projectors for better movie enjoyment.

If I enable the keystone function in the projector, will the input lag be impacted?
Yes, since image processing is required for the keystone function, input lag will be slightly longer but not affecting the smoothness in games when the keystone is enabled. Latency will hardly be noticeable with keystone function enabled, as lag time merely increase no more than 1 frame (4ms~16ms).
