With my 2 Banana Pi M3 I have a Problem with the Picture on my TV. The Screen sometimes change to Pink or to turquoise. Change the HDMI-Cable and Ports don’t work. The Support of my TV say that it is a Problem when the Banana Pi change the Videosettings. (RGB/YCbCr ??) Can I Fix these Seetings?
Probleme exit at Android and Linux.

How can I set the seetings (RGB 4:4:4 or Ycbcr 4:4:4) ??
Here are Pictures of my Problem. Please help me. HDMI-Cabel is ok. TV is ok. I had the same problem on my PC . There I was able to solve it with the setting Full RGB .
No i use only a HDMI-Cable
Hello,
there are also officells suppport? I have a big problem. I can’t use my Board.
HI: According to what you said, you were using HDMI-Cable instead of HHDMI to DVI converter, weren’t you? Have you tried any other monitors ?
Hi, I bought a banana pi m64 and get the green/pink screen or inverted colors with hdmi, 3 more hdmi cables. raspbian/android6.0/windows 10 iot.
it’s a problem with old philips and sony bravia tv because they support hdmi 1.2, and the hdmi 1.2 not support the YCbCr color, just the RGB, it’s causes a hdmi handshake/synchron problem.
Please add a function to the config file, where can we set the hdmi pixel encoding type like in the raspberry pi: "hdmi_pixel_encoding Force the pixel encoding mode. By default it will use the mode requested from edid so shouldn’t need changing.
hdmi_pixel_encoding=0 default (limited for CEA, full for DMT)
hdmi_pixel_encoding=1 RGB limited (16-235)
hdmi_pixel_encoding=2 RGB full ( 0-255)
hdmi_pixel_encoding=3 YCbCr limited (16-235)
hdmi_pixel_encoding=4 YCbCr full ( 0-255)"
This setting is a solution for old sony&pihilips tv -s with raspberry, nvidia or ati/amd pc videocards
Well known since ages but those Banana guys don’t care (or they’re not able to do software). I found it the first time mentioned for their Banana Pi M3: http://linux-sunxi.org/Banana_Pi_M3#HDMI_to_DVI_converters
Armbian guys made it adjustable for another A64 board with config file (parsed by boot script and patching DT on the fly): https://docs.armbian.com/board_details/pine64/
I found the “hdmi_cts_compatibility = 1” too, ( HDMI Compliance Test Specification ), but i’m not sure this is solution for color problems.
And i use android now, in emmc, how can i access the /boot/ folder or partition?
It is and problem is the same with all more recent Allwinner CPU. This is well known (and ignored by manufacturer) since 2015 
No idea about Android, I would believe your only hope is Android community build for A64 devices: https://github.com/ayufan-pine64 but if this Android build is made in the same way as for H3 then last paragraph of first post here might help: https://forum.armbian.com/index.php?/topic/752-tutorial-h3disp-change-display-settings-on-h3-devices/
now, i tried to edit the .bin => .fex files, but
with linux on sdcard, i can’t see eMMC storage…
if i burn android to SDcard, i can’t edit, because windows see it to raw data
what can i do now?
good board, shit support/developers, nice
