[SOLVED] Weird Display scaling issue

[georgeberlin]

Only driving me *slightly* insane...

Short version: computer with 3 displays...

One to a touch screen (control surface) and
two that connect to projectors mounted in a
museum for an exhibit interactive we're building.

The auto power-off hardware shuts down the projectors
(they didn't tell us they were connected yet) with Resolume
still running.

Before shut-off, they were reading as 1920 x 1200. Now,
Windows still sees them as 1920x1200, but Resolume will
ONLY see them as 1280x800, exactly 66% of their previous size?

After 10 restarts of computers and projectors, resetting the resolution in
all displays, starting computer first then projectors and vice versa, checking that
the text scaling in Windows is still 100%, dumping all the preferences, I got nothing.

Just won't see them as 1920x1200! Any ideas why?

Also, displays are HDMI, DVI, and Display port on a GTX 970 if that matters.

I'm going to take a leap and guess your Windows Desktop Scaling is set to 150%.

Solved it!

Somehow, resizing from 1024x768 or any other size
was RESETTING the damn 'text display size' setting
all on its own!

My other two machines don't do this!

(fun tip, switching that size higher shrinks your outputs)

It took a little of switching down on the size, resetting it to 100%, restart, repeat...
