I've just set up a new W10 desktop machine with two monitors - the
main one landscape for general use and the second one portrait for
displaying A4 sized documents in actual size. For obvious reasons, the
monitors are configured as "Extended these displays" rather than
"Duplicate these displays".

I've set up a screensaver in the form of a photo slide show. When the

Is this the standard windows slide show or a third party one?

It's the standard built-in windows slide show.


portrait monitor is on the right and the screensaver cuts in, its
screen goes blank and the slideshow takes place on the main
(landscape) monitor - which is fine.

However, when the portrait monitor is on the left and the screensaver
cuts in, the photos are half on each monitor with black space outboard
of them.

What happens of you put the landscape on the left, but reduce its
resolution such that its horizontal pixel count is no more than the
horizontal count of the other display when in portrait mode (assuming
you can - you may not be able to get it low enough)?


I haven't tested that specifically. But, with the landscape on the left,
it worked as desired anyway, with the pictures just on the landscape
monitor.

HOWEVER, I have now made the portrait monitor on the left the "main"
monitor, and the screensaver pictures are now entirely on that.

I was just wondering if this "feature" was just a response to the screen
saver finding a resolution less than it expected / desired on the
primary display.

It seems to have more to do with which is the principal monitor
regardless of resolution or orientation. If the principal is on the
left, the photos are just of that but, if it is on the right, the photos
straddle the monitors.


Next test, what happens if you position the screens as you want, but
swap the *physical* interfaces driving them?

Can't do that. The computer has VGA and HDMI but only one of the
monitors supports HDMI.

Anyone come across this, and any suggestions for fixing it? [OK I
could put the portrait monitor on the right but I really *want* it on
the left].

In theory no reason why it should not work - but that is in theory.
Sometimes a bit of experimentation is required.



I still wonder whether there's a setting somewhere which I'm missing.
