D7 lcd not displaying

I have an old Wanhao D7 without the control panel and a raspberry pi 3b+

I've almost got it working, but the screen won't display any masks or grids.

I tried using the Easy Installer from 3dprinter wiki
But the rpi wouldn't boot.
Ended up installing Raspbian, and then installing nanoDLP from the console.
Now it boots, connects to the printer, I can access it remotely from the browser, and I can control the printer.
I tried to follow the settings on 3dprinter wiki
So I added the HDMI settings to the config.txt and also imported the machine profile from the repo

Any ideas how to get this (hopefully) final hurdle passed? What am I possibly missing?

I know the LCD works, I have connected with CWX from a laptop.

I have tried using the config from the easy install (that doesn't boot as a whole) which I've included below, but it makes no difference.

# Wanhao D7 nanodlp config

#start_x=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

Re: D7 lcd not displaying

I have the same problem (build 4077). Can you solve the problem?
