How can I make iPhone apps think that no external display is connected?

I am using a 30-pin to A/V adapter, and an iPhone 4 GSM with 7.0.4 jailbroken.

I was hoping to use iFile to change a setting on the iPhone, but I'll try any solution.

Thank you for the help!

  • I saw this question the day that you posted it, and I've come back to it every day since then. I know where it should be, but I just can't seem to find the exact method that you need to override. Feb 23 '14 at 7:52
  • @Andrew Larsson Please, any clues to this would be greatly appreciated by not only me, but by everyone looking for this on google. It is something that I have not been able to find for at least a month now. Feb 27 '14 at 19:30
  • @Andrew Larsson You can make apps think that you are on wifi when actually on 3G; I don't see why you can't make apps think that there is no external display. It's puzzling! Feb 27 '14 at 19:34
  • It's possible. I'll keep looking. Feb 27 '14 at 20:56

It Works!

I installed Flex per @AndrewLarsson and entered the name of the app that was detecting the external display.

I then went under UIKit, then searched UIScreen and returned pass-through on displayOut_actualScreens.

When I tested it with my AV adapter, the app did not know that there was an external display connected!

Many thanks to @AndrewLarsson for his help! Without it, I couldn't have figured it out.

UPDATE: False alarm. It wasn't working. I had gotten overly excited and missed the fact that IT DIDN'T WORK!!! I'm really sorry about that...

  • @AndrewLarsson False alarm... I thought it was working... But apparently not. I couldn't find "Disable external screens" in the list. Mar 4 '14 at 18:13
  • @AndrewLarsson Where is "Disable external screens"? Mar 4 '14 at 21:21

  • @AndrewLarsson Can you send me the properties for "Disable external screens" I can then recreate it on my end since I can't find it. Thanks much! Mar 4 '14 at 21:35
