Help connecting ILI9341 LCD SPI Display to arduino uno
You can get it working by two methods 


using a voltage divider e.g to shift from 5V to 3.3V you could use two resistors, 100k and 200k respecfully and between both resistors there is voltage of 3.3. One for each pin that needs it.
Using 10K resistors in series between the LCD and the arduino. I really don't know how is working but it works fine that way.


I tested both methods, also the MISO pin from the LCD can be connected directly to your arduino.
