JTL it might advertise that refresh but not really do it. My old XPS has a 120hz panel that advertises 50, 60, 110, and 120. It only does 60 and 120, but it advertises the other refresh rates. Not sure why. Might be a PAL vs NTSC thing, like a holdover from European power which is 50hz instead of 60hz, which used to impact old TV's and is the origin of the "PAL is 25fps and NTSC is 30fps" thing.
