External monitor no longer appears in realtime playback external device drop down menu

[Jon Barrie]

1. Did you perhaps alter the resolution after launching PPro?
2. Are you seeing a little Yellow Hazard Icon in the bottom right, it may give you a message related to the situation (and others)
3. Could you perhaps have disconnected or stopped the Extend Display option and had it set to duplicate or off for a moment?

Usually a restart gets things back on track, just make sure the monitor is in Extend mode and not Duplicate and the connection is solid.

Hi Jon,

1. No, I didn’t. I also restarted my computer to check for this and have a fresh launch of Premiere Pro.
2. I did see the yellow hazard icon and the message was related to a resolution change on the monitor, so it advised to restart PPro to avoid any issues, I did that and the issue remained.
3. Nope, I haven’t unplugged it and the connection is stable, I can use it with other software and it works as expected, is not mirroring.

The only modification I did in the past few days is attach a third monitor, which required a driver to work, due to the fact that it is connected via USB, not the usual mini port/Thunderbolt port on my iMac. I tried getting the external monitor to be detected with the third one both attached and not, but without success.

Thanks.

Hi David,

Any changes are worth being aware of, especially if it involves the display side of your setup. I’d say something happened in there. iMac’s really arent designed for the multi-screen setup outside of the two (iMac +1 external).

Let’s try going backwards one step at a time… 🙂

– Either uninstall the driver you tried for the 3rd (USB connected) monitor or reinstall the driver for the iMac.
– Time machine would be great here if that has a step back for the driver install.

See how we go here, try to run PPro without the external monitor attached at all. Then shut down system. Reconnect the Monitor, get the extended setting working, relaunch PPro.

Let me know (Lmk) – JB

Thanks Jon, look like I’ll have to do just that. I’ll post the results as soon as I do it.

Best,

I was having a similar issue – plasma tv as ‘Realtime Playback’ monitor just stopped working suddenly. My problem ended up being that my Premiere Pro window was creeping over to the other monitor (I have them set-up side-by-side, not mirrored). This was enough to disable ‘Realtime Playback’ on my system. Sometimes the solutions are far simpler than we conjure-up in our minds..

I actually had to create an account just to reply to you. Thanks for posting this. I’m astounded how simple of a solution this was. Thanks for posting. Worked for me.
