I’ve just installed CoreELEC (S905W) on my X96 Mini and I immediately noticed the colors are off.
To test this I have 2 identical monitors side by side, one connected to my PC and the other to my X96.
The X96 seems to have a higher contrast, making the darkest blacks considerably greyer and making bright reds a bit purple.
Reading some old threads on here it seems like there was a colorspace option in the Settings->CoreELEC screen which have since been removed.
All of my displays are pretty old and require RGB 8 bit inputs.
How can I fix this?
