Hi there and welcome
This model only comes with a HDMI port on it, so you will need an adapter to convert your VGA port from your screen to HDMI so ir can connect to the Asus.
this is the adapter you require.
You plug the monitor into the Adapter and the HDMI port from the adapter into the HDMI port on your Asus and it will then display
If you like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
