Dual Monitor Setup - A question and A feature request

[jgeenen]

I am using two monitors on my Windows 10 setup. A 1920x1080 LCD tablet screen (XP-Pen Artist 22R), which I use as my main window (screen 1) and a calibrated 2560x1440 BenQ (2) which I mainly use for editing/preview etc .

PSU opens on monitor 1 and I can use the viewer on monitor 2 when using the floating viewer that I manually reposition and maximize to monitor 2

The question: Why is the option "viewer on second monitor" not opening the viewer window on the second monitor but always on the same monitor as the main PSU window? (BTW this is unchanged from PSU v5). (It is only a minor annoyance since the floating viewer option is available)

The feature request: Could the "Light table" make use of the second monitor as well?

It does on my setup ? As soon as I double click a thumbnail or click Preview it open full screen on the second monitor, same on all previous versions.

I recommend that you check your monitor setup in Windows - right click on desktop. When I had a similar problem, it was solved there.

Thanks, Jesper. Looks all normal there and other programs don't have an issue at all.

Is your second monitor set as an "extension" of the first monitor or as a mirror?

Set to extension. If set to mirror, both show the same and the setting "viewer on second monitor" sends the view into Nirvana. So
a) Windows setting extension; PSU setting "floating" -> the floating viewer pops up where it was positioned the last time - i.e. on second monitor
b) Windows setting extension; PSU setting "second" -> the viewer always shows on monitor 1 and overlays main window
c) Windows setting mirror; PSU setting "floating" -> the floating viewer pops up on the one and only screen (and is duplicated)
d) Windows setting mirror; PSU setting "second" -> the viewer icon (bottom left) glows blue but the viewer window is invisible.

Could it be caused by the NVIDIA desktop manager? I like that tool because it allows me to switch output of the active window between monitors with a hotkey (works with the PSU viewer window too, but because the screen dimensions are different, the fixed viewer window does not make use of the full screen).

I second this request!

This seems to work properly in version 2025. The Light Table displays on the monitor where images are set to display upon open. Great!!!
