I designed the hardware a couple of years ago but recently I had to do a project where I needed to use the Vivado block diagram interface. I thought it was pretty cool how fast it was to put a design together so I went about making an IP Core that controlled the PMOD.

I've check this by simply adding the resistor across the 330R and it made an improvement in brightness. Backlight current consumption increased from 4mA to 8mA. I'm going to contact the factory and speak to them about this. I do however have to make the disclaimer that any modification like this to the board will invalidate its warranty so if you do choose to modify it you do so at your own risk.

I've tried as you suggested but I thought it was still very dimmed so instead I put 110ohm resistors between the 5V and the pin of the BL resistor and it's working great so far. Your support was great however I must say when I buy a shield like this I expect to use it on a plug and play basis. Anyway, I've got 4 more of those screens to modify now arrrg.
