Me too. The moment LG releases an E6 firmware update to support HDR in game mode without any input lag increase (just as Samsung did a couple weeks ago), I'll buy this TV. HDR gaming is a MUST if I invest on any tv, with ps4 pro and xbox one s around.
I hope LG reads this forum.
I am not sure why most tv makers don't make minimizing input lag a priority, with facts stating that the gaming industry is so much bigger than movies and tv shows altogether, and that the average gamer age is not as it was in the 90's (just kids). These kids (me) have grown and will spend 3K on a set to have the best gaming experience the same way they (we) spent everything they (we) had back then importing a game from Japan. I will still have an "Ocarina of Time" keychain in my pocket by 2075.
