I connected my Laptop to my new 2320 AIO via the VGA INPUT port however it is not showing the laptop screen on the AIO monitor. It continues to show my normal desktop. It did beep but still showed my normal home screen. Is there some other setting to set up? Usually the laptop just picks up the external monitor but so far it is not working on the 2320 AIO. I saw posts in the reviews that people do it. I really just need the process of what to do on the AIO.
