I was looking for the same information. Could you help me with it. I want to connect my laptop to the TV through the Ethernet and make the TV act as a second. Is that possible? Kindly help me! Thank you.
If you want to connect the PC to use the TV as a second monitor. Then, you will need to connect them via a video cable of some sort. What type cable will depend on you finding a cable type that is accepted by BOTH PC and TV. I suggest you check the manual of both machines to find a compatible cable.
