Multiple monitors - variable and editor always open offscreen: modify Root Properties?

I have three monitors side by side and Matlab behavior finally bugs me enough to reach out... My primary laptop monitor is 1080x1920. when I open a variable or editor, it's offscreen, at [1,1] on my laptop monitor.

I think I see what's going on. I believe Matlab thinks my laptop is 1440 and uses 1,1 of the 1440 rather than 1080 constraint.

Here's my get:

    %>> get(0,'MonitorPositions')
ans =
           1           1        1920        1080
        1921           1        2560        1440
        4481           1        2560        1440

Ok now I thought I could change the matrix as shown and set to overcome this issue.

    %            1         360        1920        1080
              1921           1        2560        1440
              4481           1        2560        1440

Placing the upper left corner start at the diff between Horiz vals... however I cannot set Root Properties.

Is there anyway to get Matlab to stop being annoying? thanks in advance, Jerry
