Automatic dimming on TV UN40H6350?

Hello everyone,

I have just received my Samsung UN40H6350 TV and the picture is amazing! There's just one thing that's really bothering me which I can't seem to disable.

The TV has this automatic dimming feature, which will lower the brightness of the screen when there are low light situations going on in the programming (for example, when people enter a dark room, entering a cave, or whenever the screen is predominately black, etc). Now this is actually quite frustrating when watching movies and just watching regular TV and I want to turn this feature off.

Some things I have tried, notes:

--- I have NOT set up the wireless networking, not really interested in the media hub (I have an Xbox One)

--- I have presumably turned off the Eco settings (Menu >> System >> Eco Solution >> Everything under here is OFF. The manual states to turn off Eco settings to eliminate the dimming

--- I have Dynamic Contrast set to OFF (Menu >> Picture >> Advanced Settings)

--- I have already factory reset the TV, even though I've only had it for around 5 days

--- I have it on Home Use (Menu >> Support >> Use Mode)

--- I am in the process of updating the Software Version via USB stick.

Please does anyone have any ideas??? Thank you!

Hello Yatusabe 7,

I'm very sorry for any inconvenience this may have caused you. Have you tried disabling the Motion lighting? You can find this setting by going to Menu >> Picture >> Advance Settings>> "Motion Lighting".

Let me know if that helps!

Thank you for replying!

Unfortunately that Motion Lighting is not the culprit. When I went to check the settings, it was already OFF. I even tried turning it on and turning it back off, but the screen still automatically dims itself when it sees fit.

There must be a setting that I'm overlooking!

Hello Yatusabe7,

I'm sorry to hear that. That is all the options that would cause the "dimming" if it is still continuing, this sounds like it may need servicing.

Here's the thread where you can get details on setting that up:

If you wish to continue with troubleshooting, I would recommend calling into Samsung and asking to speak with our Remote Management department at, 1 (800) 726-7864.
