Preview not working on premiere pro when using a second monitor

[tomm.ng]

Now is about one month I got a new monitor but there is no way to make it work with premiere pro..I am using it for Lightroom and Photoshop with no issues.

I want to point out that premiere is working fine with my notebook without the second monitor attached and working in extended mode. I am currently trying with premiere 2020 14.0 version, where I had the worst results with no preview showing and audio not working.

With the version 13.1.5 slight improvements, I can hear the audio but the video preview won't work..I'm pretty desperate at this point and didn't find a way to make it work

I'm going to make a wild guess that you're on Windows and you have Monitor Scaling enabled. Only use 100% Monitor Scaling.

Ok I disabled it but still not working,..anything else I should try to do?

To troubleshoot I'd deactivate the audio for a minute and maybe focus on the video first.

In the window below; does the monitor resolution you have ticked for mercury transmit comply with the max. res.

of your monitor?

Here's a capture of my current options

Had the same error. After several weeks of frustration:

The fix: Go into msconfig and disable "Nahimic service" to keep it from running and no more crashes!

The realtek audio driver messes things up. After this all kind of troubles went away, like 

VLC and Chrome browser took ages to start. Without "Nahimic service" everything wet back to normal.

Go figure.
