HDMI matrix switch issue


Novice Member
Hi all,
I have 5 pcs 4X2 HDMI matrix switch hdr, but these switches are playing up, it is in my bard room and it keeps getting stuck.

The setup is like this:

1. 3 x Inputs 1 x always ON
2. 2 x Outputs 1 x to TV and 1 x to Projector


1. The remote is sharing the same codes as LG TV, so when I change anything on LG TV the unit changes settings.
2. The unit freezes, gets stuck and does not respond. Have to restart the unit Power On / OFF every day. I leave them always On.
3. The Audio is connected to BOSE soundbar. Sometimes the audio cuts off.

I am using AOC fibre optic cables 10m and 15m for projector and TV. Form the computer source it is a copper cable 2m.
Two more inputs to the SWITCH use AOC HDMI cable 10m, which are not being used temporarily only when a user connects a portable laptop when using the meeting room.
I contact the seller, the seller said the reason caused by the insufficient power of the AOC cable. But these cables are already in the roof they are long cables so need to be AOC, if I use copper the cable is too thick does not fit in the conduit tube.
Is that the cable issue?
