I do however find folk that have 120Hz screens asking similar questions. But it's all a big misunderstanding. The screen is 120, the input is 60 or for old HDMI 1.x inputs, 30.
Can 4k video at 120hz pass through 4k video only 60hz? My receiver has hdmi 4k at 60 hz pass through but the source connected to it through hdmi is 4k at 120hz , same like the tv. Is just the quality of video going lower when reaching the tv or the video will not pass at all?
