My bad

I checked the cable and it was null-modem so I re-wired it to straight serial and everything works flawlessly, this is one sweet display thank you Matrix Orbital

Um no, whats the difference???

Yeah come on Henry I've tried the manual reset but the display still just vaguely pulses, and I know its on the right com port as it doesn't pulse when connected to anything else

Okay I have connected up my new LCD but it doesn't want to display anything, I've made sure the com port is running at 19200 and I've reset the module, but when I start the display with LCDC you can see what it should display on the virtual screen on my monitor but the display just shows the splash ...
