You
can install the HDMI cable clip that came with your projector to
provide additional support to the HDMI cable.
Plug in the HDMI cable.
Insert the end of the cable clip anchor into the cable clip
slot near the HDMI port.
Place the open cable clip around the HDMI cable, but don't
lock it into place.
Slide the cable clip onto the anchor and lock the clip onto
the HDMI connector.
To
remove the cable clip, open the clip and disconnect the HDMI cable.
Then pinch the sides of the cable clip anchor and carefully pull it
out of the cable clip slot.
