A:Answer Nope, let me do some math for you for everyones enjoyment...
UHD Resolution, which is this LG UHDTV is 3,840 by 2,160 pixels. So 3,840 x 2,160 = 8,294,400 pixels. Thats a little more than 8 million pixels.
8K is 7,680 by 4,320 So...7,680 x 4,320 = 33,177,600 pixels. Again only a little more than 33 million.
16K is 132,710,400 pixels
32K is 530,841,600 pixels,
64K is 2,123,366,400 pixels, so over a billion
128K is 8,493,465,600 pixels
256K is 33,973,862,400 pixels.
Okay, so you'd really be looking at somewhere around 128K to 256K resolution to achieve pixel density of 18 billion pixels. Something like that would cost, well I'm not very good at math, but probably around 20 million dollars. My recommendation stick with 4K, most films now a days are still shot in 2K so you really wouldn't benefit much. I'd save the 19 million and some change and spend it on the rest of your life.
