Help for display selection

Hi,
I  would like to add a display to my future application 3" or 4" but I don't find tutorial that help to select a display compatible with Harmony.
My only criteria is that the PIC must drive the display directly without controller and it must have a pin Header no FFC connection.
My pic will be a 32MZDA not selected yet.
16 bit parallel or 4 wire SPI ???
The display must be cheap, I thought about something like this :
https://www.buydisplay.com/default/lcd-3-5-inch-320x480-tft-display-module-optl-touch-screen-w-breakout-board
with a ILI9488 controller board compatible with Hamony .
Is someone use a display like this one ?
 
Thanks you

    On the last release of Harmony v2.06 the parallel mode for the ILI9488 has been removed

    I gave up on Harmony Graphics a while back, and instead went with an intelligent display with touchscreen.
    http://www.stone-hmi.com
    With this one I use a UART port (RS-232), and same protocol for any size screen.
    I tend to draw my graphics versus using their design software as my screens are quite simple, I have a set of routines to draw a variety of button grids from array data.
     
    This way I get the display, touchscreen, and bezel all in one.

    You don't need "DA" version (32MZDA) for such a small (3.5") display. I connected https://www.buydisplay.com/default/tft-4-3-inch-lcd-module-touchscreen-display-for-mp4-gps-480x272  in a controllerless (LCC) way to a PIC32MZ1024EFG100 using harmony and it works...but ... getting harmony to work properly the fist time with a TFT is not easy or fun. I gave up after the Microchip harmony 2.06 tutorial showed to use a "deprecated" way to connect the touch panel. I'm still waiting for Harmony 3.0 :-). I hope they make things work as advertised by then.
