I'm in the UK but unfortunately I do not have a spare here – the screen arrived in 10 days or less from Aliex. I would be happy to donate some funds towards your screen for testing.

Hoping Kite will have some time to look at this soon. Until then, take it easy!

I ordered two displays and received them today. They work fine 8-)

I am using DPI_OUTPUT_FORMAT_18BIT_666_CFG2 together with dpi18_6.dtbo, therefore my config.txt looks like this:

Code: Select all

dtoverlay=dpi18_6
enable_dpi_lcd=1
display_default_lcd=1
dpi_group=2
dpi_mode=87
dpi_output_format=516118
dpi_timings=640 1 44 2 42 480 1 16 2 14 0 0 0 60 0 32000000 1
I like the overall image quality! Console text is very good to read.
The gamma setup is not very good. With the default Carbon theme in EmulationStation, the background seems completely black, even though it shows the console outlines in fine dark red lines.
The gamme can be usually setup through the SPI interface of the display. But for this display there is no documentation and they do not recommend changing the factory values.
