I have sony vaio laptop and windows 7 is installed. As you know if you press win + P you should see a window choosing a display. But it is not working on my laptop, I even changed my windows too.

please install the right grafic driver.

you can check witch version you have on the windows search or windows + R and type in dxdiag select enter. go to the tab display and look which graficcard driver you have


I suppouse your windows key is working well (Try if other combinations are working: Win + r) .

In that case, have you installed the hotfix of windows 7 (https://support.microsoft.com/en-us/kb/2581613)

You can create a shortcut with the following path %windir%\System32\DisplaySwitch.exe


Check if this service is running:

Name: Wi-Fi Direct Services Connection Manager Service

Service name: WFDSConMgrSvc

When I started this service, button started to work for me.
