be careful if your main source is SD as the cheaper 4k tvs don't upscale very good at all,also the speed at which the smart side can be crap too, I have a LG 4K oled C7 , a friend has a £500 Samsung, my friends tv looks shocking and I mean shocking, all dark scenes are like looking at snow/analog static, words are almost unreadable, the youtube app was terrible for some reason, straight lines were made up of visable slanted lines, just checked the same SD tv program on my tv and its a vast vast improvement
