TCL 6 Series (2018) Brightness Issue
I recently bought the TCL 65R617. There is an option for Picture Brightness but it doesn't seem to do anything. I'm using the built-in ROKU to watch Netflix. If I change the setting:
Roku settings / TV picture settings / TV brightness / Darker there is no difference at all. Is this setting only for 4k content or is there something wrong with my TV? The regular brightness option works, but not the "Picture Brightness" and from what I've read this is the best way to do it.
On a side note, if anyone is an expert on ARC, I'm using a Pioneer VSX-921-K receiver and I can't get any audio from the TV. I've made sure to enable ARC everyone in the Roku TV and I've enabled HDMI Control and HDMI ARC on the receiver, but I only get static.
Thanks for any help.
