If anybody has tried my solution for the ili9486 and ili9488 RED SPI LCD,
Have you noticed that the displayed image is offset by 5 or 10 pixels to the right? The right pixels are "beyond the LCD", and there's a narrow black bar on the left side.
This happens exactly the same in my 2 LCDs of the same model.
I have decoded the firmware text file, but I don't see a paramater that would control that... or at least I don't see it:

Does anybody have experience with this behavior?
Is this related to the horizontal back porch?
Command: Blanking Porch Control (B5h)
