Hello @Long Hoang ,
Welcome back to the Poly Community.
I am not fully sure I understand as both pictures you attached are blurred.
Let's begin with how long is the USB / HDMI cable connected to the unit?
Has this always been an issue or has it only recently started?
The best and quickest way forward is to contact our Support organization as the community is run by volunteers only.
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
Best Regards
Steffen Baier
