Got a new Mac Pro and a new 4K Samsung Curve TV. I am using an HDMI cable to the HDMI PC port of the TV. I can only go up to 30 Hz refresh rate. But that gives me mouse lag. Everything els OK. How can I change the refresh rate to at least 52 Hz. I have the software SwitchResX that might help. Thanks

Try going through your Thunderbolt/Display Port. Its likely a issue with bandwidth.. Possibly HDMI cable may not be able to carry the load.
