Question 2nd Monitor slowing down Main Monitor??

[SH4rpa]

I have 1 Samsung 4K monitor as my main display and a Samsung 4k Tv is my secondary. The Monitor is 60Hz@4K and the tv is 30Hz@4K. When i go to play any game it will run at 30Hz. Even when i have V-sync off ingame it still only displays a max 30Hz.

If i only make the monitor display the game will automatically go up to 60Hz like it's supposed to. Am i doing something wrong here?

The monitor is definitely set as the main display in the display settings...?
Also, try switching the cables connected to the GPU (if possible).

yes is is 100% set to main. The monitor is connected via displayport and the tv via hdmi so i will move them around and try some things.
