Hello Felipeatton,
Intel® Wireless Display requires good interaction between the OS, wireless adapter, CPU and graphics adapter. As noted in the following link:
System requirements for Intel® WiDi
Based on the model of your PC, it may have a discrete graphics adapter as well as the embedded Intel® HD graphics adapter.
Please attempt the following actions:
- Try going to device manager and disable the Discrete graphics (normally Nvidia or AMD).
- Also, you may go to the PC BIOS and make sure that the HD graphics are set as primary adapter.
If the issue persists let us know the model and driver versions shown in device manager for the wireless network adapter, display adapter, as well as the installed version of Intel® WiDi Software.
