Adding a second monitor

[igogolf9]

I have an HP EliteOne 800 G6 24 All-in-One and I am trying to add a second monitor (Acer 24" LED Widescreen Monitor.) I am using an HDMI to DVI cable. HDMI from the HP All-in-one to the DVI on the Acer. When I click on 'Detect other display,' I get the message 'We didn't find another display.'  Any assistance would be greatly appreciated.

If it does not work it may be that your adapter is not suitable.
What is the exact model of your screen?

check

For models with integrated graphics

(1) DisplayPort 1.4 port (rear)

(1) HDMI-input (rear)

Input, not output

For models with discrete graphics

(1) DisplayPort 1.4 port (rear)

(1) USB Type-C with alt mode display or 15 W output (rear)

(1) HDMI-input (rear)

Not output

Additional info:

Acer 24 LED Widescreen S240HL Abd

Hardware Interface: VGA

Connectivity Technology: VGA, DVI

Note: this model does NOT have HDMI port

Should I try using a VGA connection instead of DVI?

Any further assistance would be greatly appreciated.

Check as I showed you, the computer, has no HDMI output here
I don't have a tested DisplayPort 1.4 / dvi converter to offer, so you have to find what you need,
and it depends on the dvi type of your screen
