I tried movie mode, and it disabled the screen dimming, but in this mode everything is so opaque, I wonder if covering the light ambience sensor could disabling screen dimming and let use other modes.

I have a Samsung UN46ES6150 & use the Standard mode. I turned off Dynamic Contrast & Eco modes & this appeared to eliminate any brightness fluctuations. Standard mode supposedly uses auto-dimming but since I did not see any dimming I thought maybe the 6150 series did not have that “feature”. Maybe being a Sam’s & Costco club version that it might be different.
But I noticed if a froze the credits (white text on black background) at the end of a movie that the white lettering got brighter. When I do a freeze frame the DVR also displays a white status bar near the bottom of the screen. After a few seconds the status bar disappears & the text then resorts back the dimmer white, which is the same level as when the credits are scrolling.
IOW that white status bar affects the whiteness of the credit’s text. There must be enough bright white in the status bar to affect the overall brightness of the picture & therefore interacts with the auto dimming function.
I tried Movie mode & there is no change in the white text brightness when the white status bar is displayed. However the text looked dimmer all the time. I’ll have to go over all the settings in Movie mode see what I can do to improve that.
I previously tried to adjust Movie mode to mimick Standard mode. I just used the same settings for both but there was still a difference. Either I missed something or there are some non-adjustable differences between the two modes that cannot be changed.
I did use the AVS709 disc to “calibrate” the TV in Standard mode but will have to spend some more time playing with the settings in Movie mode.
Bottom line is the TV does have auto-dimming in Standard mode. Unfortunately.

does the motion lighting setting under advanced picture settings have any affect on what you've described above in Standard mode?

The Motion Lighting is turned OFF which IIRC is also the default. FWIW in the Movie mode it is turned OFF & grayed out so you cannot change it. I can turn it ON & experiment, but so far did not find another movie with credits of white text on a black background. I'm sure I can dig up something but ran out of time & it 's getting late.
I did experiment with Movie vs Standard modes. First I compared settings for the default Standard mode, my Standard mode, & to what I thought was the default Movie mode settings. Then watched some programs in Movie & thought they looked pretty close my Standard settings, which is not what I previously remembered. Turns out I had already changed the Movie settings so I reset them to the default & now the picture did look different than my Standard settings.
My basic settings for Standard mode are: Backlight 8, Contrast 75, Color 35, Color Tone Warm1.
I had decreased the Contrast from 100 to 75 in order to reduce a pinkish tint. Also made a few changes in the White Balance. Color was decreased from 50 to 35 while using the AVS709 disc & the Samsung’s RGB mode set to blue.
The default Movie mode has Backlight 20, Contrast 100, Color 50, Color Tone Warm2.
My roughly adjusted Movie mode had Backlight 10, Contrast 100, Color 50, Color Tone Warm1. Again, this looked pretty good.
But when I changed Movie to mimic my Standard they two did not look the same. Decreasing the Movie’s Contrast to 75 made the picture quite a bit darker, and decreasing the Color to 35 made the picture look a bit washed out. I'll have to use the AVS709 disc & see where it takes me. But so far the same settings in Movie & Standard do not display the same picture. I doubt the couple minor adjustments I did in the Standard White Balance make any appreciable difference.
Could there really be differences between the Picture Modes even with all the adjustments set the same?

Differences between "Standard" mode and "Movie" mode.
1) Standard has always-on automatic backlight dimming, also known as "motion lighting" in the menus. The backlight dimming seems to happen on YCbCr signals as well as RGB full range, but not RGB limited range.In Movie mode backlight dimming is disabled completely (except for a pure black screen, where it will also shut off the backlight).
2) Standard has stronger color saturation, approximately 12 points more than Movie mode.
3) Standard has a higher white point (contrast), approximately 6 points more than Movie mode.

I'm not trying to challenge anything I'm just trying to learn what's going on. If Motion Lighting is the same as auto backlight dimming & is always on in Standard mode, then what does the menu ON/OFF function do?
Regarding #2 & #3: Are you saying for any given numerical setting, such as 50 for color, that Standard has stronger color than Movie? Which does seem to be the case. That's probably why my Standard color 35 looks about the same as my Movie 48.
I'm presuming that Movie can be made to look the same or very similar to Standard, but it will just take different settings. I can understand having different default settings for the different Picture modes for those who want try them. But I wonder why for the same value one mode would look different than another. From your experience is this a Samsung anomaly or do most manufacturers do similar?

first, my above post was actually a quote from the link below it (I have edited it to clarify)... and I'm not trying to be argumentative either
and yes, as far as contrast and color are concerned you have to add about 6 to your Standard mode contrast setting to get the same effect in Movie mode
contrast 75 in standard mode is like contrast 81 in movie mode
color 35 in standard mode is like color 47 in movie mode
motion lighting does do something to light output since when I measure grayscale patterns with my C6 colorimeter/CalMAN 5 software turning it on makes whites somewhat brighter but doesn't change gamma... I'm sure it does more than that but I'll have to look into it another time

glad I ran into you guys- I have the dimming in dark scenes on VOD TV, and dont like movie mode for TV viewing (love standard mode). So you say copy my stnd settings to movie mode?- but it's a different mode, isnt it supposed to be different, and won't it always look different? or is it just a slot- labeled whatever and it's the settings that makes the difference?? I mean, can I really make movie mode ever look exactly like my eye popping colorful, sharp, standard mode?? Movie mode does look opaque why?? I will not get alot of the great look if I use RGB right?? I really dont like micro dimming (especially this cheap standard mode) that my UN60f7100 has?? IDEAS???

Thanks Mike99 and PlasmaPZ80U- everyone here is so amazing - I bought a welle 3D bluray lens cleaner/Home Theater maintenance suite with screen adjusting charts- I can use that right?? What about the 2 patterns in the settings of the TV- do they help at all? BTW- Actually I like dynamic contrast- its on high on my stand mode and on med for movie- Do I HAVE to turn it off?? I have all energy settings off??

+1, the AVS disc is a great free tool that actually works better than many premium discs
