I got lg oled (not the 4k one) and the picture is excellent cannot fault it. Bit pricey but if you can afford the £1800 its worth it. I was thinking 4k and nearly bought it but had a think and couldn't justify the extra £1500 atm as there is limited 4k content atm. Tbh I don't think you will see too bigger difference in 4k the picture is crystal clear
