My friend wants to display his photos from his laptop onto his TV. There is an HDMI socket on his (five-year old) TV but when the Source menu is scrolled on the TV there is no mention of HDMI inputs. I've tried every single output and none of them is assigned to HDMI. Anything else I can try? I have got the laptop working on my brand new TV with no trouble, so the fault isn't on the computer side.
