Attached are the files I used

Mick,
Per the KD8CEC naming convention, that .tft file is for the basic version of the Nextion.  The correct version for an enhanced display is ubitx_28_E.tft.  The .hmi file is the source code to be used with the Nextion editor.  One point on that, the newest version of the editor does not compile to a small enough size to fit into the Nextion displays.  You need to use the LTS version that is available on the site.

The Nano .hex file is the same for all versions of the Nextion display.

Try this file and see if that helps.
