I have a Dell OptiPlex 7040 running Windows 10.

Display always been connected via HDMI or DisplayPort without any issues.

All of a sudden I've started to get no HDMI output when using the Intel Display Drivers (530), I can load into the BIOS and Boot Menu but as soon as Windows starts to load the signal is lost

If I rollback to the Microsoft Basic Adapter driver the HDMI port outputs fine, soon as I update, back to square 1.

I have updated the Chipset, BIOS and all other drivers to see if this has any effect and also changed the Video Option from "Auto" to "Intel HD" in the BIOS but this also made no difference to the behaviour, what else can the issue be?!

If I remote onto the machine after installing the Intel Graphics Driver, I see no issues, warnings or errors to advise why no output via HDMI or DisplayPort after the OS has loaded


Another weird thing is I've plugged this machine into my TV via HDMI and it works without issue with the Intel Graphics Driver...

The monitor also works without issue with various other machines, including another 7040


I have wiped and freshly deployed this machine also, again, with the exact same results


Can anyone help me please!!! :(
