RGB Mode on S905X


I´m running latest CE Build on my S905X Box.

When i change Colorspace in System settings nothing happens.

I don´t know which colorspace is used.

Any conclusion?

Thx in advance!


Where\how\why are you changing the colospace?
Also, you need to follow up with a resolution or refresh change for the colorspace change to take effect.

In the System Settings of CE when i choose 16-235 the change does have no effect.

Also after a reboot everything was like before…

This feature can work(if it work) for rgb mode only.
By default you use yuv444,8bit

but on LE on my NUC i´ve deselected 16-235 and the system switched to RGB mode 0-255 and that is what it not does actually…

btw how can i check the actual screen mode via console?

This isn’t a NUC, it’s a completely different platform, with different capabilities.
You can see the current configuration with the following command:
cat /sys/class/amhdmitx/amhdmitx0/attr
You’ll probably see something like 444,8bit.

I just took another look, and there’s no such option in CE.
And correction to my above post, by default, cat .../attr will return an empty string.

with the latest update the option is not available anymore :wink:

It’s actually cat /sys/devices/virtual/amhdmitx/amhdmitx0/config
