isit possible to mirror the hdmi to the st7793 tft?

nopnop2002 commented 5 months ago

Since the resolution is different from HDMI, it probably won't display correctly.

You will need to create the process to import the HDMI output yourself.

that is possible at least for SPI TFTs using FBCP. there is isnt much info on the ST7793 but i did found a FB module for the ili9341 https://github.com/sammyizimmy/ili9341 and tried to modify it to work with the ST7793 but failed as i dont undersgand how that works

You need to read the ILI9341 data sheet and understand the commands.
