Hi Vishal,

Here’s my standard checklist:

* Color Depth (often default set to 16 bits or even 32 bits) need to be set to 8 bits (when running 4:4:4).

What are the 4K formats supported by the adapter ?

* Make sure the HDMI cable you are using can do HDMI2.0 or 18Gbps.

Sound a bit “easy” but many cable do actually not support the full bandwidth, certainly  not cables longer than 3 meters …

* On many TV’s you need to turn on “UHD Color” or “Advanced (Color) Setting” manually in the settings of your TV for the HDMI port to which your pc is connected.

* Also it could help when connecting 2 screens, to set the screen connected thru the Adapter as second/secondary screen

* I strongly advise you to make a custom resolution, set resolution to 3840×2160 at 60Hz and set Timing standard to CVT-RB (reduced blanking)
