You have a Himax HX8357-B controller. You need to try the 2.9.5-Beta from GitHub. This will recognise the ID=0x8357.

However it needs testing. Apparently tft.begin(0x8357) does not work yet.
Search back through this thread for "8357"

It tells you how to install the 2.9.5-Beta Library from ZIP

Then try tft.begin(0x9481) and other ID e.g. 0x9481, 0x1581, 0x9090, ...
and report back.
