I would like to connect my Macbook pro 2016 15' (Touchbar) to the LG 34UC98 Ultrawide monitor. The monitor has Thunderbolt 2 ports and my Macbook has Thunderbolt 3 ports. For the connection I need this adapter with thunderbolt 2 cable. Will the 3440x1440 resolution monitor run at 60hz or 30hz? Can someone answer this for me, I would be very grateful.
