Solved! can you connect

Can you connect a ARC compatible tv LG to a ps4 using the appropriate ARC hdmi lead?

Your question does not make sense. ARC stands for "Audio Return Channel" - a way for TVs to return audio back to connected receivers. Your PS4 (or any game console, PC etc in that sense) is "output only" device, it cannot process incoming audio since it does not have means to reproduce it.
