I've got the same issue. Bought it and a new series x console so I could game in full HD @ 120fps. Or at least 1440p @120fps.The monitor will not show anything over 100 hz,free sync is greyed out. It came with version M-T5534GCPA-1007.1 installed. After 6 days and something like 15 to 20 hours of my time I am about ready to throw the monitor in the garbage. I have just finished an online chat with a samsung "expert" who tells me I need version MJE-G51C32GLA-1000.6? I have not looked for this particular dl yet,but maybe this will solve the problem?
