Hello, did you follow this link on Recalbox Wiki ?
https://wiki.recalbox.com/en/tutorials/video/tft/tft-lcd-on-spi-bus

[proplayer2020]

@Magaki Yes its the tutorial i followed.I followed the 2,8 inch screen part and I replaced dtoverlay by the same driver but in place of 28 i put 35

[proplayer2020]

Uhh... what is the difference between spi or dpi bus???
Do my screen might work on dpi bus?

This guide was prepared with this product :
https://www.adafruit.com/product/1601

I can't ensure you the guide could work with any DPI LCD, and don't think you can rename 28 to 35 for working it.

If you tried and it's not working, no more clues for help.

Hi, I have trouble with the setup of Recalbox with the official DPI LCD screen.
The screen runs perfectly well with other OS.
I have modified the config.txt adding the Adafruit screen configuration lines as the manual says.
I tried the fkms method and doesnt work neither.
What can i do to setup it up correctly?
Thanks
