Our I2C displays are recommended for operation with 10kΩ resistors. If you disable the built-in pull-ups on the Pi, you can use 10kΩ resistors. I have done this on an Arduino where it had 1kΩ pul...

It is definitely possible that you have damaged the display, however, I would wait and test the new display you have ordered to be sure. Also, 1.8k pull-ups may not work with the display. If the ...
