Thank you for your reply, but as you can see from my initial post the devices in question meet the requirements, and I have used them successfully before. I can also see the Airplay icon in the menubar. The firewall is currently off.
Designed with an ultrathin display, the Apple MacBook Air features 1366 x 768 resolution on the 11' and 1440 x 900 resolution on the 13'.

Ipad Air Display For Mac
The problem is that there is no option to turn Airplay 'On' from within the Display preferences. The only option is 'Off.'
If you've bought a Mac mini or Mac Pro, you'll need a display to go with it; and even those with an iMac or MacBook might fancy a second screen. We've tested, reviewed and ranked the best Mac.
I genuinely do appreciate your attempt at assistance, but in looking through the various forums and discussions (there are dozens) with others having this exact same issue, I continue to see the same 2-3 articles linked, none of which actually address the issue. The problem is not the inability to stream or connect, the problem is that there is no option to turn Airplay 'On' on the Mac. That functionality seems to have been disabled upon the upgrade to High Sierra.

You can make all of your displays mirror each other, or extend your workspace with different apps and windows on each display. If you use an external display with your Mac notebook, you can also use closed-display mode.
Check your requirements
- Check the ports on your Mac to find out whether you need an adapter.
- Check how many displays your Mac supports: Choose Apple menu > About This Mac, click Support, then click Specifications. On the webpage that appears, the number of displays your Mac supports appears under Video Support.
Use extended desktop mode
Maximize your workspace with extended desktop mode, which lets you enjoy full-screen apps and windows on each monitor. Then, use Mission Control to organize apps and windows across your displays. If your Dock is on the bottom of your screen, it appears on any of your displays when you move your pointer to the bottom edge of your display.
