Hello all,


lot of us are out of color from AutoDimming ( CE Dimming) feature implemented in 2012 ES series of Samsung Smart TV. On german hififorum I found interesting information, how CE dimming works...

author is Dideé : (google translate)



"The automatic dimming takes effect if the average brightness value of the current image (or scene) is smaller than a certain limit. By raising the brightness (at the very beginning of the processing chain is) will ensure that this limit is never reached. And the very end of the processing chain standing white balance makes the raised brightness then reverses. So this is a high stability a "work-around".




I tried it and I can confirm IT WORKS:


How is it in real life :


My former settings (STANDARD mode)


backlight : 11

contrast : 74

brightness : 45

sharpness:0

color:34

...

...

White balance (advanced settings)
R-G-B offset : 25-25-25

R-G-B gain : 25-25-25


Using test patterns from calibration forum, namely level blacks 0 to 4%, and two day of comparing and testing with real videos etc, I have found, switching CE Dimming off starts at brightness 50, and each +/- 1 step makes big difference.

Raised level of black (brightness) can be compensated by R-G-B offset.


below are my new settings, CE Dimming is almost switched off - not noticeable. Clouding is not visible (night test WO ambient light, black remains deep black), picture color tone seems to be OK :


backlight : 10

contrast : 90

brightness : 50

sharpness:20

color:40


White balance (advanced settings)
R-G-B offset : 15,15,14

R-G-B gain : 26,25,9


gamma:0


Try it, it should work on other models from ES6xxx series, I believe on whole ES series.


For complete settings please see post nr 21 in this thread.

Thanks for the information. I applied the settings to my ES6550 and it seems to have corrected the auto dimming problem. I did have to increase the color to 49.

VERY Interesting. Thanks for posting this. I'll give it a shot this weekend.


This....

"below are my new settings, CE Dimming is almost switched off - not noticeable. Clouding is not visible (night test WO ambient light, black remains deep black), picture color tone seems to be OK"

..... would indicate Micro Dimming (which can't seem to be had in Movie mode, nor had without CE Dimming in other modes) is still active without CE Dimming becoming a nuisance.

I can't thank you enough for posting this information. I gave it a try, and YES, it does work!


I cannot say that the auto-dimming is completely disabled, but it's virtually non-existent now. Not only that, but micro-dimming seems to still be functioning since the blacks seem noticeably deeper and the clouding is almost unnoticeable now instead of how it is in movie mode.


I'll play around a bit more with my own tweaks for color and it seems you can still do that in white balance, so for instance, previously my white balance was:


R-G-B offset : 20-25-25

R-G-B gain : 10-25-25


to compensate for the red push my ES7500 has. So I started with the tweaked settings, and then adjusted it by taking away 5 points from the R-offset and 15 points from the R-gain:


R-G-B offset : 7-12-12

R-G-B gain : 10-25-25


And the auto-dimming is still virtually absent. You can clearly see the difference because if you pause a film with a black screen and a single name or credit at the end of a film, and then switch over to dynamic or natural, you can instantly see it auto-dimming and there is a major reduction in brightness. You can also notice the menu brightness is much much better, not affected by auto-dimming like before the tweak.


You should also be able to do this in the other modes as well like natural if you tend to use that mode (not recommended but sometimes you might find a use for it).


The best thing about this fix for those like myself and garnoch who use movie mode to avoid the auto-dimming: it's a buy 1 get1 free fix - you virtually eliminate the auto-dimming, while at the same time greatly reduce the clouding because micro-dimming seems to still be active! This is the best news yet about this set - I could actually be happy using standard mode now and not be annoyed by the dimming, while hiding the clouding.


Such an easy fix - why couldn't Samsung have given us this tip? Great find!

Unfortunately the picture was far too dim on my PS51E530 with these settings and the colour looked washed out. The auto dimming feature was also still very much present.

PRSUT, thanks again for this tip. We've linked to it and talked about it in the 8000 thread. I'm surprised that I may like Standard mode more than Movie mode now. I'll give it a couple of weeks to see what I think long term. I did have to tweak for my setup so that I didn't lose to much black detail. These are the settings I settled on for my panel....

10-27-12 STANDARD Update to counteract CE Dimming (whole screen dimming during dark scenes)

Changes because of this setup are in bold


Picture Menu:


Mode: Standard


Backlight: To your liking, mine is 12 (3 or 4 lower than Movie mode)

Contrast: 98


Brightness: 53

Sharpness: 16

Color: 45


Tint: G50/R50




Screen Adjustment submenu:


Picture Size: Screen Fit (16 x 9 for TV if you don't want possible data visible on top or bottom, this will slightly zoom & degrade picture though)


Position: [no change]




Auto Adjustment submenu: [Grayed out]



3D submenu: N/A




Advanced Settings submenu:


Dynamic Contrast: Low


Black Tone: Dark


Flesh Tone: 0


RGB Only Mode: Off


Color Space: Custom


Color Space submenu:

Red: Red 50, Green 0, Blue 0


Green: Red 4, Green 48, Blue 4


Blue: Red 2, Green 6, Blue 46


Yellow: Red 52, Green 50, Blue 4


Cyan: Red 0, Green 50, Blue 51


Magenta: Red 40, Green 6, Blue 44




White Balance submenu:


R-Offset: 17


G-Offset: 17

B-Offset: 14


R-Gain: 5

G-Gain: 26


B-Gain: 20


10p White Balance: Off [grayed out]



Gamma: -2

Expert Pattern: Off


xvYCC: Off


Motion Lighting: Off [grayed out]


Black Enhancer: Off


Picture Options submenu:


Color Tone: Warm2


Digital Noise Filter: Off
 (Auto for DirecTV)


MPEG Noise Filter: Off
 (Auto for DirecTV)


HDMI Black Level: Normal (If available, set to Low for DirecTV or other STBs if picture looks light and cloudy)


Film Mode: Off or Auto 1 (When available)


Auto Motion Plus: Clear (Off can be less smooth - other settings give more Soap Opera effect and can stutter picture - personal pref)

LED Motion Plus: Off (On is suppose to help with fast motion - I have yet to see it make a difference)


System/ECO Solution:

ECO Sensor: ON

Minimum backlight level: To your liking, mine was 7 and now is 6

Just wanted to add that these adjustments also work very well on the ES7100 series.


Brightness is 53 and offsets are all set at 17.


Thank you!!!

yeah, that right, i think so,Unfortunately the picture was far too dim on my PS51E530 with these settings and the colour looked washed out.

You have a plasma television. This trick may not work on plasmas

Is your television a multisystem???

Hi, I have just purchased a Samsung 46" ES6710 and was wondering if you have the time could you advise me on the best setting for this TV?

Any advice would be much appreciated.

Thanks

Ray.

So what would be the best settings for UN55Es6100 ? Best calibrated settings for this 55' HDTV? Also I don't know if this is a problem on other Samsung HDTV but do you ever notice a faint ghostly horizontal lines when camera pans up and done and side to side during darker scenes? I noticed this while watching Blu rays, watching Dish, and playing Xbox360 and everything is connected using HDMI. Is there like a perfect setting to eliminate that? It might not be noticeable by most but I do happen to notice it. Thanks for help

This is called horizontal banding and is related to panel hardware so it cannot be resolved by pictured menu settings. Even top range sets (es8000) as any edge lit panel can have horizontal or vertical banding. You can try to replace panel, but then you are at risk with clouding and flashlighting....

So it is normal then? Will it get worse over the years? Right now it's very minimal though.

Hi prsut,

thanks for the CE dimming and calibration tips.


Which R-G-B offset applies with the last standard mode calibration you posted (Edited 2/2/13) ? 12-12-12 ?




Thanks again !

Thanks again !

In few seconds I will post NEW calibration settings with my new meter i1 Display Pro + Chromapure.
