Hi, they sent me a Displayport Adapter with:
DisplayPort (20 pin) Male Latching
and
DVI-I (29-pin) Female
Neither connect to the HDMI cord nor the monitor.
Also - should the MacBook Air recognize when a monitor is connected? Do, if it was working, in System Preferences in Display would I see it? (I did not when I used the HDMI cable and HDMI/USB adaptor) OR is there some setting or command I must provide to tell the laptop that there is a monitor attached?
If I can't resolve this by tomorrow evening's appointment with the Geek Squad, I'll look at buying a PC and stop using Apple. Apple doesn't seem to have an external monitor option, and it's very difficult to get non-Apple people to help.
Thank you for any assistance you can provide
