IPad 4 lightning to vga adapter, works but gets stuck in video out mode. I can't get it to switch back to mirroring without restarting it

Question

I have an iPad 4 with an Apple lightning to vga adapter. (A1439)
It connects fine to my HDTV and projector for doing presentations and video etc.
But if I do show any video on it, e.g. full screen a video from within Chrome, Safari, the apps for Youtube etc.
or if I do a presentation using Keynote, it locks into working as an extended second screen.
It shows the controls for the video on the iPad and the video on the external screen, which is what I would expect. But then if I exit the video or complete the presentation, the external screen continues to show the last frame of the video or presentation. Even if I close the app.
I can't get back to using it in mirroring mode without shutting it down and restarting.
Surely I am just missing something.
I've tried force closing the apps that I use, switching between them, starting up new ones etc.
But no luck.
There doesn't seem to be a setting anywhere that I can change.
Any suggestions?

The same thing happened to me. After the big update, I also experienced exactly what you described. I ended up restoring the ipad a number of times.
The first few times, I restored from a back-up. The last few times I have restored the ipad as new. It would work the next few times I turned the machine on, and around the third time, it would lapse back into the recovery mode, with
the image of the serial cord connecting to an i-tunes logo on its desktop. This morning, I restored the ipad as new, but only allowed the apps manufactured by Apple to be synced back onto the ipad. I have powered it back on about three times, and so far, so good. I am waiting to see what happens the next few times I turn the machine on.
I had a very helpful senior Apple express advisor help me on Sunday to do the restore as a new ipad procedure. He said that if that did not work, the next step was having it serviced. He also mentioned that often the third party apps have problems due to getting corrupt and this often happens after a major update. That is why I thought i'd try and see what would happen if I only synced the Apple apps back onto the ipad.
It is not good though if I can't put third party applications on it without having the problem of lapsing into recovery mode, so I may have to get it serviced. I am wondering how many others have had this problem after the big update last week? Also, has anyone who was an early purchaser and got the flat-rate unlimited data plan subscription from AT&T, had to have their ipad replaced? Was there a problem with AT& T still allowing you to continue your special subscription plan?
