Manual HDMI color range settings

[noxifoxi]

I'm not sure if I'm in the right place here. But I can't find anything on the internet but abandoned threads in the steam forums.

In my case, I have a TV which only supports full range HDMI, but doesn't send the device that it supports it. The result are washed out colors and reduced contrast, what really bugs me. I can't set the TV to limited color range like I said and the Steam Link doesn't have a setting to force full range.

Is it possible to add a setting to force the HDMI color range setting in the Steam Link Firmware?

Or is there at least a way to force it over SSH or a config file on an USB-drive? But even if, a setting in display settings should be the way-go-to solution.
