I have a Samsung 4K TV that I am using as a Monitor. It is very sharp and i don't notice any motion artifacts etc. However the monitor Properties shows that the refresh rate is only 29 Hz. It will not let me set the Screen Refresh rate to 59/60 Hz even though I know that this display will do 59/60 Hz (See attachment)

There are lots of reasons for this issue. Typically it is because the underlying DisplayPort port is shared, the DP-to-HDMI converter (LCPCon chip) only supports 29/30Hz or a poor quality HDMI cable is being used. Provide the information that Leon mentioned above and we will look at isolating the possibilities.

How are you connecting the unit to the TV? Using the Thunderbolt 3 (USB-C) connector or the HDMI connector? If the former, then I blame the dongle or the HDMI cable. If the latter, then I blame the HDMI cable.

I've analysed the SSU report and founded two questionable installations:
I'm not sure that this will fix your problem, however, I would give a try.

I appreciate the leads for this issue. Some more details.
I am going to take this TV to work and connect it to my work PC which has an add-on NVIDIA graphics card, connected to a Dell 4K monitor that is currently running at a 60 Hz refresh rate to see what happens.
Thanks again.

The following steps are for Windows 10 running the Creator’s Update:
Hopefully you’ll be good to go by now. Still, Windows 10 can be wonky with HDR displays, making colors look weird because it doesn’t know how to map colors from the sRGB color space to HDR properly. To get around this, make sure to disable ‘HDR and Advanced Windows Color’ from Display Settings. Apps that do know how to use HDR – games, for the most part -will generally do so on their own.
And that’s it! Enjoy your gigantic, 4K HDR monitor.
