iPad OS 17 HDMI out not working

For what it's worth, having tested connection of iPad Pro models with an external monitor via both a USB-C to HDMI Adapter - and a USB-C hub with in integrated HDMI port, I've not encountered any issues of this nature with iPadOS 17.x.

If you are experiencing difficulties having performed the update, try a forced-restart of your iPad - as this will often clear post-update or isolated software issues:

Force restart iPad (models with Face ID or with Touch ID in the top button)

If your iPad doesn’t have the Home button, do the following:

1. Press and quickly release the volume button nearest to the top button.
2. Press and quickly release the volume button farthest from the top button.
3. Press and hold the top button.
4. When the Apple logo appears, release the top button.

Force restart iPad (models with the Home button)

Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.

If you continue to experience difficulties after performing a restart, you might be well advised to seek assistance directly from Apple Support. You can contact the Support Team using the Support link at top-right or bottom-left of this page.

Alternatively, you can initiate and manage your support cases using the excellent Apple Support App. If not already installed on your iPad, the App can be downloaded from the App Store:

I figured out that I need to restart my IPad with the HDMI connected via the Satechi pro that I am using into the IPad and then it seems to sync with the monitor. I know some monitors may be picky on HDMIs. Now I am able to see a screen and not just a mirror image. I have stage manage working but I have to force restart the iPad every time I have to use the external monitor once I connect it.

So try keeping all connections in place and then restarting. That’s how I finally saw an option for arrangement of screens and turning off mirroring of the IPad screen.

Hope this helps and this issue in IPad OS can get solved soon as restarting every time is starting to get old.

Here is a post I did before.

I just got a new monitor from Dell S3422DWG and when I connect it via HDMI I can only see a mirror image of the iPads screen. The monitor is a UHD 4K monitor. I was previously using another monitor LG 35WN65C-B  with stage manager and it was working flawlessly. 

Now I don’t have any options and mirror is the only thing I’m see on the Dell monitor. No other options and it’s like previous generations where it mirrors at a low resolution.

Do you know if there is a list of monitors that are Not compatible with IPadOS 17.1? Second guessing why I got an iPad if it can’t even connect to an external monitor. iPad is still not ready to compete with a Mac quite yet. My old 2014 Mac book air connects properly as another control. 

Have you tried or have you experienced the only mirror issue? Any thoughts on resolving this issue? 

Note: I have tried resetting both monitor and iPad. Actually erased the entire iPad thinking that might fix it but to no avail.

I have gotten a solution to my problem, or a workaround. Requires more cables. An external audio device via usb that the iPad supports. So I have a "Fujitech Type C Dock" connected to my ipad with usb c. From there I have and hdmi out cable and get the image. I now connected a "TODN type c to 3,5mm jack aux audio usb c dac" cable to the usb port on the Fujitech with a usb a to usb c plug and I can choose to have all audio run through that device instead of the hdmi port.

If I then would need the audio to come back to hdmi I could use a audio to hdmi injector and end up with audio in the hdmi. In my case, I don't need to have the audio in the hdmi. I have my ipad connected to an Atem Mini and run LiveApp on the ipad and get full screen hdmi out with audio in sync.

THIS WORKED thank you!! My lightening to HDMI connection stopped working right after I did the 17.1.2 update. After reading your comment I restarted my iPhone 13 Pro while connected by the Lightning to HDMI cable to my Insignia LED TV, and was able to continue streaming HBO Max.

I restarted my iPhone 14 Pro updated to 17.1.1 with the Lightning to HDMI cable already connected to my Roku TV and it worked for NetFlix and Slide Shows and Play Memory videos. At first it did not work when I first updated to 17.1.1 and tried the Lighting to HDMI cable.

Thank you for the restart iPhone while connected to HDMI Dock connector device! I also had to restart my Roku TV which is what my iPhone 14 Pro with 17.3 iOS was using with the dock connector. Now all my apps are playing without issue, including Prime Video!

It looks like there is a possible bug with the OS 17 update. I found if trying to mirror with the computer, if you press mirror again, it will show up. I haven't found a temporary fix on the iPad. Hopefully there will be an update to fix this update bug. I listed the Apple TV link that talks about the bug.

I'm running on iPadOS 17.0.3. (iPad Pro 11-inch, 4th gen.). I have my ipad connected to an HDMI mixer (Atem Mini Pro), once i force restart the ipad connected to the dongle I det a sound via the HDMI twice when it starts, one of those os sounds when you start the device, clearly also visible via the audio bars. Once I start any app, I won't get anything out. If I then go to settings and play with ringtones, I get them out via the HDMI and have them clearly visible in the audio meter. If I use Safari or Chrome to watch YouTube videos, I get the audio, if I launch an app, Youtube or Spotify, I get nothing.

I have the same issues with iPadOS 17.1 YouTube app not giving audio out via HDMI at all, Spotify works if you have it playing a song when you connect the usb-c cable, but not if you have it connected and start the app. Very disappointing reactions on the matter from Apple, one would expect quicker reaction since their updates broke something that was working earlier.

Update: I am able to connect both MIDI and Audio via Bluetooth, but to get the Audio Out (similar to HDMI issue), I have to disconnect and reconnect the audio link manually after turning on the piano. If I don’t do that, app doesn’t think I’m using external audio. Definitely a nasty bug in 17.1.2. Having to do a hard restart just to get this to sometimes work is NOT a solution.

I updated iPhone 14 max pro from iOS 16 to iOS 17. Now my HDMI (adapter) out to TV does not work.

And what’s funny! I have a WiFi router on my semi truck that I could connect my phone and tv to a home network and mirror, but I get charged data (hot spot) if do it that way.

Thanks Apple

Still no good with 17.1.2 . I downloaded the update and still cannot put a Keynote presentation on screen. This is an incredible oversight by apple. I suspect many users who can't rely on apple products to do presentations will start looking elsewhere.

I have a similar problem with MIDI / USB Audio Out to an electronic piano. Sounds from the training app I use used to play through the piano speakers, but no longer after update to 17.1.2. Restart with MIDI / USB Audio connected does not work.

My situation is SO frustrating. I plug in the adapter and sometimes it works and sometimes it doesn’t. There is no way to predict.

I thought whatever update I had (now 17.1.2) fixed the problem. But today I couldn’t get it to work no matter what I did. Unplug/plug it in a bunch of times, hard restart of my device, nothing. I was about to give up watching and then it magically worked.

Absolutely no rhyme or reason on this. I have no idea what to do. Frustrating as ****!!!

This is ridiculous! Hdmi works fine on 14.8. 17 is garbage.
