Display problem using a TTGO T-display

[kalon33]

Using a TTGO T-Display (and having activated that option in TFT-eSPI), I got a display problem: only part of the display is used, and with the wrong rotation. I tried changing it without success (only part of the display is used).

Here is a photo from my problem:

And a photo from the other side of the board for more info about it:

Could you help me to find how to fix that?

Best regards.

I think you have the same board as I have, the problem is that you have to change the user_setup_select.h, uncommenting your corresponding line (mine is Setup25_TTGO_T_Display.h) and also you have to change the driver used in the file user_setup.h. I have commented line 39 and uncommented 49. User_setup_select.h

I hope this can help

I am also experiencing this issue with the same board as @kalon33 after making the changes suggested by @Perchindroid . Could I be missing something else?

Fixed!

Simply needed to comment out the default setup file: https://github.com/Bodmer/TFT_eSPI/blob/master/User_Setup_Select.h#L20-L22
