Second display on HDMI1

[alex_g2]

2 monitors, connected to HDMI1 & HDMI2 at the back of the desktop. Only the monitor connected to HDMI2 works (both monitors, both cables tried on this, no problem switching between the cables/monitors, so have ruled out faulty cable and faulty monitor).

Can't identify / detect the second monitor (whichever is connected to HDMI1).

Only 1 display adaptor, and 1 monitor listed in device manager - scan for new hardware doesn't find the second monitor.

Have tried uninstalling the devices/drivers.

Any ideas?

Welcome to the HP Support Community!

I recommend you update the BIOS and the graphics driver from the below link and check if it helps.

Thanks, updated the BIOS and the graphics driver as suggested, and the monitor reappeared on the system.

Happily back to 2 monitors!
