LG 43UN700-B HDCP Errorrs

Hello, i have a 2019 Macbook Pro 16" 2019, i just purchased LG 43UN700-B 4K USB-C (TB3) screen.

It is connected to the MAC, working as intended and detected as a 4K monitor.

However, when i try to play a UHD HDR Content via VUDU or Netflix or similar i get an error:

"Oops! This title won’t play in this quality on your display due to copyright restrictions. It can be played only if your output and display support HDCP."

The error is in chrome, when trying using safari it will only play in HD (1080p) but not in 4K and not in HDR.

There are no specific drivers to download (like in MAC), i downloaded and installed the LG app for MAC and firmware is the latest.

The screen is connected using a USB-C TB3 cable (came with the monitor), and all settings looks normal. however i am still unable to get 4K HDR video to play.

Any advice would be appreciated, TIA.
