Hi there I'm awaiting delivery of a Sony 4K TV and have a couple of questions please.... 1. Will I need to purchase a 4K HDMI lead to connect the Humax to it? 2. Will the picture be upscaled to 4K from my Humax with/without a 4K lead? Apologies for my ignorance but I'm getting conflicting advice elsewhere but have confident that the right answer is on this forum! Thanks in advance, Rg.
