Dell Display Manager not working with AW2725QF

The options are grayed out. (I have changed from U2723QX to AW2725QF)

The connections are as follows 

[Computer]->[HDMI]->[AW2725QF]->[HDMI eARC]->[SOUNDBAR]

[AW2725QF]->[USB-B]->[COMPUTER]

OS: Windows 10

Both DDC/CI and HDMI CEC are on.

Any solutions?

I checked the report and it shows:
