I understood PMDG NGX shows the label of the knobs and switches when positioning the cursor using the mouse. I have not seen this working in mine.

The tutorial for the 1st flight says : ".......by actually physically rotating the wheel with your mouse while the cursor is positioned over top of it. An FSX tooltip shows you the current value of the trim."

Can anyone guideme to turn this feature on?

I use the NGX 800 wing tips default. This is the new version since I down;loaded and installed it today.

 

when you open fsx go to settings / customize / aircraft tab / and check if you have the box ticked where it says "show cockpit tooltips"
