RE: no signal from hdmi


When did the issue start on the machine? Was it working fine earlier or is this the first time you are trying to connect via HDMI? What is the OS installed on the system? Could you try using a different HDMI cable?

Update the BIOS - http://dell.to/1JZP8qH

Reinstall the video drivers from the link above or from the vendor site as below:

Download and reinstall the video drivers from the vendor site - https://downloadcenter.intel.com/ and http://www.amd.com/ for ATI Radeon drivers or http://www.geforce.com/ for Nvidia drivers.

If you are unable to find the related drivers, then reply with the current OS installed and a screenshot of the device manager with display adapters extended and we can provide you the link.

Keep us updated.
