Inverting pixel clock affects only picture quality. You should see the picture anyway. Try to check your DEN signal. It should conform the datasheet.

I want to introduce my project with NHD-5.0-800480TF-ATXL#-CTP
Beaglebone LCD cape.

Linux 3.8, 3.15 and rowboat android.
The 7" LCD is coming very soon.

I confirm that it works with using DEN and inverting pixel clock. 8)
I didn't touch R4. I just provided signal DEN from CPU.
Thank you.

Just tried another LCD - the same result. So it is something with init sequence or some difference that I missing. My controller works perfect with NHD-5.0-800480TF-ATXL#-CTP
My question is - what the role of DEN signal? I grounded it in NHD-5.0-800480TF-ATXL#-CTP and also here.
And in the power sequence diagram you mention signals: AVDD, RSTB, STBYB, VSD. I can't find them at the LCD connector. What is important in power sequence?

I have my own controller. I tried to change parameter in my module "pixelclk-active <1>" to "pixelclk-active <0>". No change.
Can you confirm that it is the same pinout and timings as 5 inch LCD?

Just received this LCD from mouser. According to Datasheet it has the same pinout, voltage and timings as NHD-5.0-800480TF-ATXL#-CTP. When I connect this LCD to controller that works with 5" LCD - I see white backlight with vertical lines on it.
Can you suggest something?
Thanks.
