2) Backup the files to your computer, format
the
USB drive, transfer the files back to the drive,
and plug the drive into the projector to play
again.
No signal after connecting a device by the HDMI
port?
There are 3 HDMI ports on the projector. Please
make sure you connected to the correct one,
the
HDMI wire is good, and the HDMI device is
power
on.
No sounds?
Check whether the correct audio output (built-
in
speaker / external speaker) is selected for audio
setting, and whether it’s muted.
Not clear image?
1) Make sure the video is high definition
originally.
2) Check the projector is in focus: go to Settings
-> Display -> Electric Focus to adjust the focus.
Keystone correction function?
Supports improving the image distortion
problem
by software; but the function can only work to
some degree and will impact the clarity of the
image. Therefore, you’re recommended to
eliminate or reduce the distortion by physical
means.
How to choose the audio output?
When connecting to a speaker, in the settings
you can see two output options: PCM and RAW.
1) For PCM output, the audio source is
decoded.
It features wide compatibility, meaning working
with almost all types of speakers; but the sound
quality would be compromised.
2) For RAW output, no decoding is involved for
the audio output, thus retaining the original
sound (as long as the speaker connected
supports the decoding of the audio).
Generally RAW output is the optimal choice.
