FOUND A SOLUTION
Here's the steps I followed.
Change the main display Scale to 100%. (This step may not be necessary, but I did it anyway to rule out any issue with application scale.)
Go to this folder: C:\Program Files (x86)\FinalWire\AIDA64 Extreme\
Right-click on AIDA64.EXE and select Properties.
Select the Compatibility tab.
Select "Change high DPI settings"
Select the bottom option and change it to: "Override high DPI scaling behavior. Scaling performed by: System (Enhanced)."
Click OK to close the tab's setting
Click OK to close the Properties.
Set the main display Scale to 150%.
Run AIDA64.
I tried this and it works! I rebooted my desktop, opened AIDA64, and the sensor panel displayed on the 1280x800 LCD panel in the correct font size! Since I had disabled "Load AIDA64 at Windows startup", I enabled this option, rebooted, and it still works fine.
The one thing I cannot tell, and I'm not sure I want to experiment with this, is that the AIDA64 application font appears to remain unscaled, that is, it's not respecting the main display's Scale of 150%, but instead, is remaining at 100%. For me, that's not a problem as I am only using AIDA64 for the Sensor Panel.
