When I bought my Newhaven displays, the pinout difference stood out immediately to me in the data sheet.
On the Lumex, and all other displays I've used, the Vss, Contrast, and Vdd pins are laid out in a row with the contrast in the middle like the pins on a pot usually are, with a voltage across the "outer" legs and the wiper in the middle.

The out of sequence power / contrast / ground sequence caught my eye right off.

Sorry I didn't mention it sooner. I didn't think about it until the word "Newhaven" came up again in one of the later posts and sparked a brain cell....

I hope that's the problem for Jellis00 !
