We do not have internet at our home due to living in the country. I have used my hotspot on my phone to bring up you tube videos that say 4k, even 8k, but I think I read her that its not 4k. Is that true, the picture is really good but I don't know if its 4k good. I have a 65 inch LG 4k tv with the Hopper 3 and a pioneer receiver that has most of new video and audio settings
