I'm on the look out for a good 4k TV. Having read all the reviews etc, it seems that the decent 4k tvs start at around £2k. The LG OLED 55C7 and newely released Sony A1 OLED seem to be the best TV's according to every review I have read. The LG has just been halved in price from £3k to £1499 in Currys. Does anybody have this TV?
