Full screen preview with 3 monitors?

[defaulth0jzk7qo8vuf]

I recently added a third monitor and would like to use it as my preview monitor, the other two monitors being used for timeline, and bin. When i had two monitors, all I had to do was either assign the playback monitor in the project settings, or manually enter a full screen preview when my panel is on the desired screen... Ever since adding a third monitor, this has all stopped working. 

When i have panels open on all three monitors, the full screen preview only covers about 1/4th of my screen (1080p monitor). This doesn't happen, however, if all of my premiere panels are on one screen. Simply put, I can use 2 monitors and have a full screen preview. If I'm using all 3 monitors to spread out my panels, full screen preview doesn't work on ANY of my monitors and I get a partial preview.

This is extremely frustrating, as full screen preview seems like an extremely basic feature that a video editor (ESPECIALLY A PAID ONE) should have figured out. Multiple monitor full screen preview is extremely, extremely basic in a video editor and if this can't support a full screen preview with 3 monitors it's pretty hard to call this a professional editing program.

I should add:

- I've subbed out the 3rd monitor with several other monitors, the same result applies.

- I've subbed out the other monitors as well, in the event that maybe one of them was causing the issue.

- I've reinstalled graphics drivers

- I've considered changing editors

Hoping that I'm just missing something stupid...

As noted in another thread, I have four monitors in use. And no problem whatever in getting a full-screen output.

A main monitor with the 'home' menu screen on an Ultrawide, 2560x1080. The transmit out option always goes to my UHD monitor. A third, 1920x1080, has a panel 'grooup' on it in my custom workspaces where I have the Production/Project/Bins/Source panels. The fourth monitor is small, and I use it to drag 'floating' panels if I need one.

Never an issue. So not sure what the problem is. Do you have the Premiere main window dragged across multiple monitors?

Hi, I suggest to set scale to 100 % for all monitors in display settings and see if it fix your problem - "preview only covers about 1/4th of my screen".

Sorry to hear you're having trouble with video playback to a dedicated display.  It's usually very straightforward.

What do you see in the operating system display settings for multiple displays and for the display information of each display?
Windows11 > System > Display > Multiple Displays

How does that compare to what you see in Premiere Pro when you go to Preferences > Playback and view the Video Device List?

Premiere Pro > Preferences > Playback > Mercury Playback Video Devices List

Display settings and/or display drivers are the most likely cause of this kind of issue.
