TFTs / NHD-5.0-800480TF-ATXL-CTP Yellow Tint
« on: August 31, 2015, 08:03:41 PM »
There is a distinct yellowing on my display.  Not sure why.  All of the colors are there, but there is a yellow tint over areas, especially a band through the middle 1/3 of the display.  Any idea what can cause this?

TFTs / NHD-5.0-800480TF-ATXL-CTP Shifted Right
« on: August 31, 2015, 05:08:06 AM »
I see other posts about this but no resolution.  I used the values from the datasheet, but my display is shifted right by about 20-30 pixels.  I am using an STM32F7 with the following settings.  I verified most of the timing.  Do my values look correct?
