Kurt,
I did give your suggestions a try. I dropped the SPI clock freq to 20^6Hz and still no dice. I also downloaded the beta TDI but from what I Can tell, no changes were made to the ili9341_t3 library between the latest release and the beta.
There are other examples of running this exact display I have on the T4 and from what I can see, I've got everything in place. I found a guy that had schematics and code just shortly ago and I'm pretty convinced that I popped something in the display.
I would like to contribute back to this community in any way I can so this may be an opportunity to do that with a comprehensive thread on using these displays with the 4.0, options with the libraries out there, some benchmark tests, and some tweaking of the libraries to see if more performance can be had.
