Intel HD Graphics 4000 no signal through HDMI on my Toshiba laptop

[MGall13]

It simply shows "no signal" message. It started suddenly. Without any software or hardware change. Please help.

I attached diagnostics files.

Laptop recognizes the monitor.

Thank you for the reports. It seems to be driver issue, if possible try updating to the latest version 4425.

Please give it a try installing the driver linked below: https://downloadcenter.intel.com/download/25977/Intel-Graphics-Driver-for-Windows-10-and-Windows-7-8-1-15-33-?product=81499 https://downloadcenter.intel.com/download/25977/Intel-Graphics-Driver-for-Windows-10-and-Windows-7-8-1-15-33-?product=81499Allan.

Allan, thank you!

Unfortunately it didn't help(

Is it possible that it is because of hardware problem?

Since you are testing the software (drivers), it might be hardware with the HDMI port on the computer. Please check with Toshiba for possible warranty options: http://forums.toshiba.com/ http://forums.toshiba.com/
