Hm, interesting. So it is only 1 DP 1.4 port to get 4K 120 Hz, hence at 8-bit. So it is not using MST mode, as it is limited to 96 Hz in HDR (10-bit) mode.
Also of note is the input lag numbers averaged around 35ms, but that isn't taking into account any input lag to the laptop screen. So it could be higher. That was taken using the HDMI 2.0 port though, so it may be a hair faster at 120 Hz.
