Question: sky q what tv do i need?
Answer: No, an HD TV is fine. A 4k TV is needed if you want to watch Sky's relatively limited UHD content. If you take a mini box as part of your subscription, you'll need to pay for Q Experience, which also unlocks UHD on the main box, so when you do come to get a 4k TV, you'd not need to pay more for UHD content.
