Skip26570: Thank you very much for contacting the Intel® Graphics communities. We are sorry to hear the laptop is not working properly.

 

 

In this case we always recommend to install the drivers provided by the manufacturer of the laptop, in this case Dell:

Did you try to un-install the graphics driver and re-install it again?

 

Did you try to disconnect and re-connect the HDMI cable?

 

 

Please provide the SSU report so we can verify a few details about your system:
