Hi guys, normally I'm OK with picking out TVs but, this time I'm stumped. Brand new technology. Anyways. I'm looking for a 65' 4k tv with HDR and your advice on what the best brand and model would be for about £500 to 900. Main uses is going to be hd gaming, bluray films, series. Any advice? Thanks guys.
