Hi all. I've just got a lg cx and wondering what to set in the Xbox video settings in regards to playing warzone at 120fps. Do I set it to 4k at 120fps or 1440p at 120fps? Searched the internet but can't seem to find a definitive answer. When I bring up the freesync info on the TV it shows around 120fps set at 1440p but between 2 and 5 he when I set it to 4k. Now I know its not 5fps but will it be running 120fps when set to 4k?
