    Hi Michael,

    Sorry to hear that you are experiencing issues with the display. It may be necessary to adjust the execution time to resolve the problem of double characters appearing on the screen.

    For screen dimming, have you tried swapping to a second display to see if the issue persists? Also, could you please confirm if the problem is still noticeable when testing with the Arduino? Additionally, it would be helpful if you could provide information on the supply current and voltage being provided to the display. Lastly, could you please share a picture of the backside of the display that is not functioning properly?
