Have you got the room to mount the TV on a wall? If so you possibly get a 39, 40 or 43 inch 4K TV. I have a 43 inch Toshiba and the 4K is prefectly fine for me with that size. An added bonus is the set I have also has a satellite tuner alongiside freeview play.

As an afterthought if you do decide to get a 4K TV, it may be worth checking on the BBC website to see if the BBC 4K content is compatable with the TV you chose. Most of their test programs in 4K use a higher standard. For the full benefit, you will need a 4K HDR TV that supports HLG.
