Hi,
You recommend to use the dynamic contrast option in order to brighten up the picture in HDR Game mode, which on this older model has a very dark average picture level out of the box.
Does this option have any impact on the input lag in game mode? Making it higher than the measured 21ms? Not sure if you have the answer considering this is an older model, but I can imagine such an option hasnโt been changed much on newer models.
