Can’t get TFT to work

Did buy a 3.5” tft for mega (and others say text). So it wont need a shield for mega, i was thinking that i can use it for Due also without shield.
TFT uses ILI9486, 16 bit bus and are 480*320.

My project need UTFT so i locked in dokument for that. ILI9486 should be supported with CTE40 or directly with ILI9486.
So this was my statment for UTFT:
(CTE40, 38,39,40,41) didnt work, only a white screen.
Tried (ILI9486, - white screen.
Tried every driver in UTFT yesterday But only white screen.
Tried with Mcufriend.. white screen.

Going mad about this.. anyone has an idé?

Could be a number of reasons, but your post doesn’t have enough information. The chip could be different and you are trying wrong library, the wiring is wrong, it need resistors and voltage dividers on all data connections, etc. I’ve seen these screens come with a cd or a link to download examples and libraries. Ask person who sold you for it.

Thanks for your answer.

I have asked the seller but no response...

I use MCUFRIEND ID with DUE to see what that say:

Read Registers on MCUFRIEND UNO shield
controllers either read as single 16-bit
e.g. the ID is at readReg(0)
or as a sequence of 8-bit values
in special locations (first is dummy)
