Roku premiere dims picture too dark after dark with living room lights on. Have to turn on a light next to TV to correct brightness. Running on Samsung UN40 TV HDMI input 3. All other HDMI inputs are not auto dimming. Can auto dimming be turned off?
Thanks for the info. Article is for a much newer Samsung than mine. Mine is a 2016 without the Eco settings. But it did help to know that each HDMI had separate settings. I then went to my HDMI 3 and then to Settings/Picture/Picture mode and change Standard to Dynamic. I had to wait until evening to see that it fix my dimming problem.
