Hi f_mhamad,

 

Welcome to Lenovo Community Forums!

 

First open the Device Manager and Open DIsplay Adapters

Uninstal the Intel Graphics and make sure to place a check mark in the Delete your driver software prompt and continue with uninstalling.

 

Make sure you restart the computer before downloading and installing this Driver

Let me know if this worked for you.

Regards

Solid Cruver
