[SOLVED] Getting Nouveau to use Limited RGB with HDMI?
My TV looks too dark when connected to my Nvidia GeForce 210, seems like it expects limited RGB (16-235).
I have laptop with intel GPU so when I connect the TV to the laptop everything is good, but when I set "Broadcast RGB" to "Full" everything gets dark. Setting it to limited makes it good again.
I played around with EDID files without success. IDK what to do since xrandr doesn't give me any of the useful options it gives for the Intel GPU.
Any way to do this when using nouveau?
Output from xrandr --verbose

Re: [SOLVED] Getting Nouveau to use Limited RGB with HDMI?
I don't know about nouveau, but you can reach the same result with a little trial and error using xcalib by modifying brightness and contrast and displaying a black to white gradient to tune them. (lower the contrast and push the brightness)

Re: [SOLVED] Getting Nouveau to use Limited RGB with HDMI?
Thanks for letting me know about xcalib!
It worked after 5 minutes of trial and error.
I tried with xrandr and got no good results when adjusting gamma and brightness. What xcalib does differently?
EDID:BTW, it's still better when I connect to intel GPU but xcalib makes things very acceptable for me.
