Tagtool crashing with projector

Tagtool is crashing every time I try to connect to the projector. It’s not the cable I still watch movies with iPad and projector.

I have exactly the same problems. It’s because of the Apple update. And the problem is not solved.

With the upcoming iOS 11.3 the external display is working again. Only reconnection is still not fixed - you need to restart the app every time you connect a display. But it´s working again.

Looks like it will be released next week. Or if you cant wait - you can get the public beta from Apple at beta.apple.com


@iink Hi!
Do you think its safe to install the beta version?
Because im actually in a hurry !


If you really need the external display connection of your iPad the beta is the only way. Backup your iPad before installing just to be sure to have a fall back option. The Beta itself runs fine so far - i don´t have any issues.

great! im using it and it ´s working perfectly.

This was really helpful thank you . I had an event which had to be cancelled due to this problem. I referred to this thread but unfortunately The Apple beata install didn’t work for me on the evening . I’ve now been able to get it connect to my projector so I hope I won’t incur this problem again.

Maybe some of you will find this useful, with my iPad Air running 11.3 I noticed that if I want to connect Tagtool through my wifi to the projector I need to make sure “screen mirroring” is not on and Tagtool is not launched. Then I need to launch Tagtool first then launch the screen mirroring and all works fine. (If I try to screen mirror, then launch Tagtool, Tagtool crashes).

Hello guys, I’m using IPad Pro 12.9 first generation with iOS 11.3 but it’s still not connecting, as soon as I turn the app on with the projector connected it crashes, any ideas? Thanks!


You need to start Tagtool first - and then connect the external display. Only this order works so far.

Hope that helps.
