Hi ive recently bought this board from here
the output for LCD ID NEW is as follows

Read Special 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)

diagnose any controller

any help on the driver or the id of this would be appreciated. I just cant seem to get anything but the white screen

This seems to match the board you have. There are downloads for libraries and documentation.

Thanks for that ... Yes ive been there installed it into the ide. And just the white screen .Ive tried the adafruit version also MCUFRIEND... compiles uploads yet white screen i also have another screen with a 8230 chip in it and that worked almost straight away with the MCUFRIEND_kbv library (on an uno).... I didnt think the bigger screen on a mega would be causing so much trouble for me maybe i was spoilt with the first one

But this board uses an ILI9488 chip.

Thats what i mean was easy as pie to get the 8230 chip one to work but the ILI9488 has me pulling my hair out.
