Roku TV "TV Brightness" Setting

Does anyone know how the "TV Brightness" setting (Darker, Dark, Normal, Bright, Brighter) works on Roku TVs? 
Does it cap the brightness range of the TV? e.g. if using Darker, the maximum screen brightness is capped at say 70, minimum at 0 vs Normal, max at 90, min at 10?
I see that regardless of the setting I select for TV Brightness, I can adjust the Backlight from 0 to 100, but how do these two settings work together?

Re: Roku TV "TV Brightness" Setting

I believe it's the same as the Backlight control on other TVs, changing the overall level of the backlighting. Yes, that differs from what the brightness and contract settings do.

TV Brightness affects the overall brightness of the TV and applies to all inputs.  The other Backlight and Brightness settings are per-input, which means you can have different settings for streaming, the various HDMI ports, composite, and the tuner.  There, Backlight controls the brightness of the backlight, while Brightness controls the way the picture data is modified in the video processor.

Re: Roku TV "TV Brightness" Setting

So other than the brightness of the TV interface, there is no difference between the following for a given source?
1. TV Brightness = Darker / Backlight = 80
1. TV Brightness = Brighter / Backlight = 20

Re: Roku TV "TV Brightness" Setting

I would suggest that you set TV BRIGHTNESS to NORMAL as a baseline and then dial-in your BACKLIGHT and BRIGHTNESS settings per input (i.e. HDMI, Streaming, OTA) as stated in Post #3 to your visual preference. Then use the TV BRIGHTNESS to adjust for the current ambient light in the room based on time of day and lighting you may have on. I personally prefer to keep my TV BRIGHTNESS at DARK and then will occasionally bump to NORMAL or BRIGHT if time of day or content is too dark. But, most of the time I find DARK works well to keep the blacks from washing out for most SD content.  All of these comments are based on my PICTURE MODE preference of NORMAL with a WARM color temp setting. MOVIE was just too much of a yellow haze on most content for my liking.
