I have a Early 2009 Mac Pro with GeForce GTX 680 video card.
Just bought a UN48JS9000 Samsung 4k TV and can't get it to work at 60hz.
Tried connecting it by itself, with another HDMI display and nothing helps.
Any ideas? Should I install nvidia drivers? I'm out of ideas on what needs to be done
Here is a screenshot of graphics property.
I'm using Club3D Displayport 1.2 to HDMI 2.0 UHD adapter
