120Hz should refer to the refresh rate of the panel. But HDMI 2.0 does not support 4K 120Hz signal transmission. HDMI 2.0 only supports a 60Hz screen refresh rate in 4K screen transmission; HDMI 2.1 only supports 4K 120Hz screen transmission. As long as your host's performance supports 4K image output, you can display 4K images on the TV, but the HDMI 2.0 screen delay may be slightly higher than the computer monitor, but whether it is 4K interpolation algorithm or native 4K, you are watching now, there is few difference.
