Sorta solved the problem...loaded up a fresh (7/10) copy of Buster desktop and contrary
to directions, got the 3 all set up with a regular HDMI monitor.: did the updates, and set up the resolution, from the 1920x1080 to 320x480 which is native for the display. Then I went into the LXTerminal and increased the font size to 12 and "bold". Then I went into lcdwiki.com
and followed instructions for the code to enter. That results in an automatic reboot and when it returned, all was happy. Problem is solved..."sorta" because the field of view is still very narrow and a horizontal display is not readable unless looking straight down on it. So I am still looking for a decent solution to get a decent viewing angle. Oh well!
