WiDi don't Work

Hi all,

I recently bought a SAMSUNG ATIV smart PC 700T , and a Toshiba LCD TV (Widi enable)

I upgrade my Samsung with the samsung tool and Widi 3.5.40 is installed and  Intel WIFI card 15.6.1.20

TOSHIBA LCD TV is up to date

When i lauchn Intel Widi to detect adapter !: "no adapters detected"

Firewall is compeltely disable

When i search the device in windows 8 (DLNA) i can see the device, it is possoble to connect to ..

Can someone helps me to resolve this issue , and eventually explain how WiDi works (TCP ports, etc..) ?

Regards
