Solution:

In order to enable the HDR with 4K@60Hz(nVidia), please follow the below steps  

1. On TV in SETTINGS -> GENERAL -> EXTERNAL DEVICE MANAGER -> INPUT SIGNAL PLUS -> (select the HDMI with your PC) -> ENABLE                                                                     

2. On your PC open NVIDIA CONTROL PANEL -> CHANGE RESOLUTION -> CUSTOMIZE ->  define your custom requested resolution using the data of E-MANUAL Read Before Connecting a Computer (Supported Resolutions)

E.g. For 3840 x 2160 @ 60Hz the CREATE CUSTOM RESOLUTION screen has to be set like this on NIKE-M:                                                                     

Horizontal pixels: 3840                                                                       

Vertical lines: 2160                                                                      

Refresh rate (Hz): 60                                                                     

Color depth (bpp): 32                                                                     

Scan type: Progressive                                                                        

Standard: Select first AUTOMATIC and then change to MANUAL; afterwards                                                                        

Make sure that Refresh Rate under "Horizontal" matches the frequency listed in E-MANUAL                                                                     

Make sure that Pixel clock matches the frequency listed in E-MANUAL                                                                     

Make sure that Polarity matches the polarity listed in E-MANUAL                                                                     

3. Click on the TEST button                                               

If The resolution works well then agree with saving The resolution and use it from now on                                             

I recommend to set the OUTPUT DYNAMIC RANGE to LIMITED

4. On your PC right click on the desktop and select DISPLAY SETTINGS-> enable HDR and WCG
