I just recently picked up an Alienware 34 inch ultrawide (AW3418DW) and im planning to use both my gaming machine and my MacBook Pro with it. I currently have my gaming rig plugged into the DP port and its working great at 3440x1440 at 120hz, but I just found out that the monitors HDMI port is locked at 50hz at 3440x1440. I would really like to have my MacBook Pro be at 3440x1440 at 120hrz but I only have one DP port on my monitor. Are there any good DP switches out their? I found some on Amazon but they are only capable of 60hz. Any recommendations?
