I've asked this in other similar posts: how do you even buy one of those? I went to the equivalent LG website for my country, and they don't even have a button for contacting them like in the link above. So I did some searching for the model "LG UT640S" and I only found it sold on one website in my country, but listed as a smart TV (full number: "LG 43UT640S0ZA", parent ends in S0UA). What gives? Do you need a company to be able to buy one of those? Maybe a sort of line of credit with LG? Buy in bulk? None of this makes sense honestly. I wanna buy a product that clearly exists in the world, but I can't even find someone, somewhere, that will sell it to me.
