So I'm considering to make the step to a 4K/UHD TV. One of the drawbacks of a 4K/UHD TV is the amount of input lag that's introduced when you run a 1080p/60Hz signal into it. Even the fast Sony's are a lot slower (about 2x) than their FHD counterparts.
But I can't shake the feeling that current input lag tests are not that representative when using 4K/UHD content. The most common testing uses a Leo Bodnar lag tester and that outputs a signal at 1080p/60Hz. With a PC, you can just let the PC/GPU handle the upscaling (virtually lag-free) so you simply feed the TV a 4K/UHD signal at 60Hz.
Thing is I can't find any tests that actually test this scenario. I assume the input lag will be less if the TV doesn't have to upscale, but I can't be sure without actual numbers.
Anybody any thoughts or tests that I could check out?
