Thank you.  Along with your path browser report, things are much 
clearer.  With variable pixel densities and custom settings, we cannot 
use fixed pixel or even mm numbers. 114 is right for me because I have 
Display Setting "Change the size of text, apps, and other apps, and 
other items" to 125%.  My taskbar is 11+mm high.   78 or something near 
that is right for 100%.  150% would need more than 114.

Under 'Advanced scaling settings', one can enter a custom scaling size. 
Is this what you meant when you said you set scaling to 200% or 100%.

No need to post what you wrote.  Let me summarize the numbers I want 
along with mine for comparison.

What I need to do now is examine the tk screen sizing system and 
functions and see if the needed numbers (max usable height for zoom) are 
available.  If not, I might add a 'Calibrate screen' item under Options.
