We have for years had a tv in the kitchen which is linked to our main telly & sky box by a coax aerial lead & we could watch sky or freeview in the kitchen, recently i bought a new smart tv for the kitchen & we can no longer get sky in the kitchen, there is only one HDMI outlet on the sky box that is connected to HDMI 3 outlet on the lounge telly, can i connect another HDMI lead from either of the other two HDMI outlets on the back of the telly & plug into the HDMI outlet on the back of the smart tv in the kitchen ?
