    Hi Al,

    Thank you for the detailed description of your issue. The two displays should be fully compatible in software and wiring. However, there was a change to the NHD-0220CW-AB3 models in 2022 that affected the applicable voltage range of the display. As such it would be helpful to know what revision of the display you are using in addition to what voltage you are supply the display and how you are setting pin 3 (REGVDD).

    If you were using the 2.8V operation for your existing setup, please note that the change in the voltage range of the newer displays is for 3.3V typically. While they can still function around the minimum voltage (now 2.7V) a drop in power can cause fault to the display operation and would require a full reset to resume normal operation.
