External Monitor Not Displaying Properly

For whatever reason the custom scaling option on the HP monitor is greyed out, so I’m not going to use that monitor.

The other 2 monitors that I have both have VGA connections, no HDMI option. I have one monitor currently hooked up via the hub using a VGA to USBC adapter and it’s working fine.

The reason I purchased this hub is to use 2 external monitors. In order for me to hook up my second external monitor (it has a VGA connection), what adapter is best to purchase?

Does it need to be an active HDMI to VGA adapter (that needs to be plugged in for power) that I run through the active HDMI to Displayport adapter that came with the hub?

Can I get a DisplayPort to VGA Adapter like this one:
