Display settings for E0700G8DH6, pixel clock has to be inverted

We are using the NetDcuA5, connected to a 800x480 TFT display.
Up to now we used an EDT display, supplied by GLYN: ET0700G0DH6.
This TFT was changed to: ET0700G8DH6
Using the same settings I now have shadows on my display. The supplier told me that I have to "invert the Pixel Clock".
How can I invert the Pixel clock?
Which of the registry settings of the display do I have to modify?

THANK YOU

THANK YOU.
I will test it on Monday.

I tested it and it works. Thank you.
Where can I find and download the Device Driver documentation?
