I just now watched a Netflix 4K program thru my Hopper 3 Netflix app on my LG 4K TV. The program info said it is 4K and my LG magic remote verified it was in 4K mode. I backed out of the Hopper and fired up my 4K Fire Stick and watched the same Netflix program thru the same LG TV. The info says it is HD and my LG magic remote verified it was in HD mode. Why the two different modes? I also fired up my other 4K LG OLED TV and watched the same Netflix program thru my 4K Joey Netflix app. The program info said HD and my LG magic remote verified it was in HD mode. I don't understand why all the differences! Both TVs user guides do not mention if all the TV HDMI inputs are the same. All HDMI cables are from DISH.
