1. My laptop is a 2014 MacBook Air running macOS Mojave version 10.14.2. My Android tablet, being used as a second display, is a Google Pixel C running Android 8.1.0. When I first downloaded the apps, I was on a public WiFi, and the two systems would not communicate.
2. Since I need an extra display in my work environment, I cannot connect my tablet (Thompson TO13P, a 13.3") on the secured corporate wifi (need certificate).
3. Too bad, would have been great.Extremely bad performance (especially in comparison to the free Spacedesk app), mouse doesn't work, no sound (the main reason I bought this app, as Spacedesk doesn't support audio) and it even causes glitches and slowdowns on my Windows host.
4. Now I see that they took out the USB connectivity! (only wifi allowed) WORST: the extended display [wifi] is not working: it cannot even start.
5. I did reach out to the developer twice using their online help form, but I didn't receive a response after waiting a week after each request for help.In light of the negative reviews of this product, I felt it worthwhile to document my experience.
6. Initially I manually entered the laptop's IP address and port, but the Android side of iDisplay was able to auto-detect the Mac and connect.
7. At least I got my money back using a Google Play refund.Super! Only a few more features that would make this a hit and be nice to have: 1) full screen with no task bar.
8. Returning home, I had no problems getting the two systems to communicate, and as I write this I have my tablet displaying a second application.
9. It's not a high speed link by any means, and I would not recommend playing Minecraft on the Android second screen, though it can be done.
10. Only the (useless) extended display [wifi] function is working.
11. A few years ago, after buying it, I discovered in their FAQ that the extended displayed function has been put on hold for stability reason.
