The love in the comments section is insane - I've never seen so much admiration and gratefulness. What an awesome tip to share.

[@arthemisboss]

Hello man, I have a Q60T like you and disabled dimming. I'm seeing some color innacuracies, like too much blue in some scenes. Can you please share the values in the service menu of the sections ADC/WB->ADC Result and ADC/WB->White Balance, including the greyed ones? You don't have to change anything, just share the values, please.

Thank you so much. I honestly don't understand who the geniuses were at Samsung who thought, "hey let's make the thing gain or lose two stops on every edit!" was a good idea.

I can't thank you enough for uploading that video! I have my TV for about 1 year now, and I liked the picture, but I always noticed that there was something weird with the dimming in dark situations. I searched it up on the Internet many times, but I never found a way to change the dimming. I just don't understand why this weird setting is preset and why you can't change it in the standard settings.

Yeah, it makes no fucking sense. It really pisses me off how they give you menu options that don't actually do anything. Turn off all eco settings, yet the screen still becomes unbearably dim when I turn the lights off. Thank god this service menu exists

[@yyr_]

I cannot thank you enough for posting this video. The auto-brightness was just absolutely infuriating. We found 100 to be way too bright, so I just set all of the PWM settings to 55 and it looks wonderful. If anyone from Samsung is reading this...PLEASE in the future make this an option that we can simply turn on or off from an easily-accessible menu, such as Picture > Expert Settings. It could just be PWM: Auto/100%/75%/50%. Most folks will just leave it on Auto anyway.

[@scottish-atechreviews]

My PWM Max was only set at 70 for some odd reason?

[@Augury666]

Yeah i don't like how black looks with everything at 100, it you set it at 55-60, black must look darker but can you notice the dimming? it's difficult to find the perfect balance between good black while impossible to notice the dimming.

[@bluebull399]

I think they do it to show off deeper blacks. However, most people would actually prefer greys and being able to see more. Probably the only show that would suffer and look washed out is Ozark.

[@kmorgan7263]

This worked brilliantly, dunno why it can't just be done in the standard menu, dynamic contrast sucks and should always be off

[@neilmckie2768]

Excellent - I've got a newer TV and to get onto the service menu it was INFO - MENU - MUTE - POWER. After that just the same, but instead of four zeros to access the additional menu, I held the volume UP button for 7 seconds, and hey presto. Massive improvement in picture - don't feel like I need NVGs to watch the telly now, lol Thank you very much

[@vanta654]

Are you able to adjust your Backlight after using these settings?

[@keithhouse4969]

Vanta so after I pumped all of these up to 100 the backlight settings didn’t dim much. What I ended up doing was playing with the settings a bit so my TV would dim some. I think I put the movie setting around 80, the min at 30 and the mid at 55 or so. I like these settings a lot and I can manually go in and adjust the brightness to my liking and it will only dim just a little bit on the dark scenes which I am ok with. Ya with everything pumped to 100 I did notice some ghosting in the corners of my TV. These setting fixed that quite a bit and I’m very happy with it now.

[@7RodrigoAndrade]

I can’t thank you enough man! It worked perfectly on my TV, the new model TU7000. You’re awesome! Quick Note: Apparently, when the TV system updates, we have to do the process again, but this time was so much easier because of you! Greetings all the way from Brazil! 🇧🇷

Sir... I thank you! I've been through two repairs, about 9 different phone calls with Samsung customer service and no matter what I was stuck with the dimming.

THIS FIXED IT! Thank you so much you have no idea how happy you have made me! This worked perfectly. By the way does this void any warranty at all?

I was getting ready to just pass the TV along to someone else because I couldn't stand it! I wonder how many TVs get returned because of this. You'd think that Samsung would have a user mode to turn this crap off. Having to go into the service menu to fix this is inexcusable!

[@zockbobomb3048]

Only change PWM_INI_2D and PWM_MOVIE_INI in 100!!! Leave other settings at default (MID: 8, MIN: 0.) PWM_INI_2D effects Game Mode. PWM_MOVIE_INI effects all other modes. This is enough to stop dimming. Otherwise u can´t change your Backlight anymore. Full 100 is not good for dark rooms. :) Remember: Make a picture before you change any settings in service menu. Don´t change other settings without knowledge Default Service Menu Settings: 2D INI: 15 MOVIE INI: 30 MID 8 Min: 0

I fixed it . Thank you! I just wonder why Samsung has this annoying function to get the dark scenes darker.. Better black ok but you miss the details of the scene.

[@bigmoney66b]

To enhance darkness but also to help eliminate blooming around high contrast images with surround areas of darkness....... The threshold is too high though, the black levels are quite decent on newer TVs without needing this. I cannot understand for the fuck of me, why Samsung has not added the option to switch it off. The settings provided on this video are not ideal, personally to help extend the life of the LED backlight, I use lower settings. The PWM 100 is optimal with max backlight. On my TV I set backlight down to 20-25, and I only change MIN and MID PWM to 60, 60, I lave PWM INI_2D at 15 and PWM_MOVIE at 30, just the MIN / MAX at 60, combined with backlight to anything between 20-25, otherwise if using PWM 100 all the way the backlight offset is higher causing it to be brighter - by lowering it down to 20-25 it will extend life of LED, and by the time it reaches its half life you will have, you will have a good window to increase backlight, as opposed to using the defaults max backlight, when it dims you will have no margin to increase it. The only side effect is that daytime viewing will be less than ideal with low backlight setting, but keeping your backlight at max or near max is not an ideal condition for a TV. These LEDS last NOWHERE near their advertised specs, it is hype - it is probably under the BEST of conditions and cool environment - otherwis HEAT is killer. A more realistic average is 15k-20k hours half life (before losing half brightness). If you leave your backlight MAXED OUT you will likely end up with burned LEDs long before the advertised hours, due to heat, unless your home is at ideal cool temps in the summer - but still..... These crappy LCD monitors, even newer ones are not meant for long life, it's no wonder they sell CHEAP NOW and you can get a cheap 4k, the companies want you to buy a new set every few years. At MAX backlight, if you are lucky and under the best conditions, your TV will last at most 2-3 years before significant dimming and/or LED burn. With 50% lower backlight + ideal environment and ambiant temperatures, maybe 4-5. If you want a long lasting TV, stick to CRT.

[@thanoskalentinis826]

@@bigmoney66b I have only changed pwm_movie at 100. So auto dimming is not working in movie and hdr modes. So I can choose if I want it on or off. Also I have the backlight at 10 (max is 20) so I don't think I will have problem with burning leds.

Samsung fucked up with CE DIMMING, period. CE dimming is so abrupt and obvious that everybody hates it. They should give everyone to turn this off without having to go find a special remote and go into a special developer mode. Its so stupid...WTF are they thinking. After 5+ years of people complaining you'd think they would learn to just put it in the picture settings and give people the choice. It really upsetes me because I prefer curved TVs and they're the only ones that sell budget ones and they all have CE Dimming like the rest and if you dont have the right remote or Phone with IR to enter this mode youre fucked and just have to deal with it. I know this because I have a 55' TU8300 and the CE Dimming is terrible and I just want it OFF.

@@rick330 I too would love to disable the HDR picture adjustments so that Netflix does not get so dark. I just bought a 2020 Q70t. Nowhere near as good as my 2019 Q70r.

[@LOBOFERZD]

any updates? I have q70r and it's very dark some scenes

[@NitroCigarette]

I really really REALLY can't thank you enough for this. I could have sworn something was wrong with my TV and was becoming so frustrated. This fixed everything. Earned a sub.

[@StevenLyall]

Ignore my last post - my Custom Colour Space settings had been reset (maybe as a result of this procedure), but no worries - easy to re-enter them and well worth the effort. Thanks again - awesome!

[@HEARD201]

It worked! Anyway you could put up how you do your picture settings?

[@landogambino6727]

When I turned off my tv the settings had reset. Is there a specific way I’m suppose to reboot it?

[@JohnDoe_333]

TANKS!!! Also works on my 2015 UE55 TV. However you changed to many settings, to disable the "auto dimming" in dark scenes it was enough to set the "INI"-Values to 100. When you set the PWM Mid/Min to 100 you always have your backlight at full brightness. Also don't forget to make a photo so you can restore the settings if it somehow doesn't work for you.

[@HellLordBR]

thank you sir... worked great on my 55RU7100 (i had to use a remote control from other samsung tv, the mute 182 power worked)!!! that global dimming thing was really annoying! i only changed PWM_INI_2D and PWM_MOVIE_INI to 80 both, no need to change the other ones.... anyway, thank you man!

[@jedirabbit6275]

I’ve changed mine all to what the video says but I think I’m noticing the screen too bright after and wonder if I’ve adjusted too much or not what I’m meant to, like you said you have only changed two to 80 and has worked. Do you recommend this?

[@vanta654]

@@jedirabbit6275 Screen is too bright because the TV is no longer able to adjust Backlight automatically. You must change PWM Max setting to around 30.

[@Link23809]

Newer TVs have improved the global dimming algorithm to the point where it isn't that noticeable anymore. The problem with setting these values to 100 is that even on a pitch black screen, the TV won't dim properly and will show all the faults in the screen (clouding, flashlighting, bleeding, etc). So some form of global dimming is still good to have on. The same applies to a FALD TV. If you disable local dimming you will see the inherent flaws of LCD technology. I recommend people leave the default values or just bump them up a bit, but not all the way.

[@daverich2499]

The ONLY settings you need to change to completely stop auto-dimming , are PWM_INI_2D, which stops it on all picture modes except movie, and PWM_MOVIE_INI which stops it on movie mode. The higher the number the less it dims and on 80 it will not dim at all to the human eye as far as i can tell, but you can set it to 100 if you like. The Min setting should not be touched as it will force the backlight to whatever you set it too at all times making interval scenes where the screen should be 100% blackwith all lights off stay at 100% light making things very distracting. Ignore min and mid, never touch them, leave them as they come, and change above only. This is all you need to ever do to disable the annoying auto-dimming. P.S in the UK it is INFO, SETTING, MUTE, POWER while tv is off to enter menu.

[@NiftySquares]

If it's too bright, change the PWM Max value to around 60. That will change the brightness of the TV panel

[@HellLordBR]

thank you! it worked perfeclty as you said.

[@delivrex]

Cheers mate!

[@EntombedHusk]

Dude, what are you talking about? The sole reason why we change min and mid is to stop adjusting the brightness automatically. I don't care if it's up or down. I want it the same forever. You say that it doesn't raise the brightness... But then you proceed to say that it lowers it..? THAT IS THE PROBLEM! I still don't understand what does min and mid does exactly to be honest.

[@EntombedHusk]

@@daverich2499 DUDE! We don't want the backlight to change EVER! That's the whole point of this video.

[@jamesbarrows488]

Anybody try this with a Q90T? I've made the "Advanced" menu appear, but when I highlight it and press "0000" nothing happens. Was the password changed in a firmware update or something? Edit: For later models, instead of 0000, hold volume + until they appear (roughly, 5 seconds).

[@JustOneGuy]

THANK YOU!

[@marekw2537]

What options is it worth to change without damage tv? Is it possibile to do factory reset and revert all the changes ?

[@NiftySquares]

There is no factory reset for the service menu. You could check out the W/B Movie settings in the Advanced settings. Make sure to take pictures before changing values

[@victoriastable1]

Thank you so much for this video. Worked like a charm. I only changed the PWN_INI_2D and MOVIE_INI too 100 and left the rest alone. Again, thank you so very much. Problem fixed!

[@saullandiof5768]

dude you're the best, this the only tutorial that works

[@pcjoshua1]

Thanks dude for the brilliant info however i couldn’t pull up the advanced settings by pressing 0 four times on my Q60T. Any help appreciated.

[@CheesusSweet]

I have the same issue. 0000 doesn't work.

[@tmarioman]

what country was your Q60T purchased from? I am trying to learn if this works for 2020 USA models because it is not working in Europe.

[@arthemisboss]

Hello man, I have a Q60T like you and disabled dimming. I'm seeing some color innacuracies, like too much blue in some scenes. Can you please share the values in the service menu of the sections ADC/WB->ADC Result and ADC/WB->White Balance, including the greyed ones? You don't have to change anything, just share the values, please

[@Felipe-bl4rg]

Thank you so much for the instructions! I have a question that perhaps some of you can help me with. I've tried this on my Samsung Q70R and none of these settings are really working. The one with all the levels to 100 didn't do much and the updated one for the 2020 models didn't work either. For some content it does diminish it, but for HDR (especially Netflix and Prime) it is still very apparent. Does the Q70R have some special settings I need to consider? Thanks in advance.

[@LOBOFERZD]

I also have the q70r, and in dark scenes it is dark demsiated I see nothing, is there any way it will clear up? please help!!

[@rafngard]

I followed the directions and it did not work, but figured out it was because the TV was in "dynamic" mode. Changed it to "standard" and now the fix is working :)

[@NiftySquares]

When you come out of service mode by restarting your TV, the eco settings, ambient light control is turned back on. Check to make sure those are turned off before setting your TV.

[@thekorben]

Used this guide for the third time after a recent update (which the TV decided to do even though I turned off auto updates). Thought it was time to leave a heartfelt thank you! :)

[@Chris-Alia]

What are the default settings before they’re changed? I messed something up and need to tweak it back for a minute

Ciao Dario. Ho letto tanti commenti e tutti positivi su questa soluzione. Non ho capito bene però quale problema risolverebbe. Lo chiedo a te perchè parti italiano... io mastico l'inglese ma per una questione cosi tecnica preferirei parlare nella nostra lingua madre :D. Grazie in anticipo

[@Brudax93]

@@mauriziob.3062 Ciao Maurizio. Questo video dà la soluzione per un problema molto fastidioso che affligge tutti i TV, qui in particolare si parla di TV Samsung. Per fartela breve: quando la TV visualizza scene molto scure la luminosità del pannello si abbassa automaticamente rendendo le scene più scure ancora più scure! Ad esempio succede anche quando cambi canale: ci sono pochi secondi in cui l'immagine rimane nera per qualche istante con solo il numero del canale evidenziato sulla destra (o sulla sinistra, non ricordo) e in quel caso vedi il pannello che abbassa la luminosità in modo importante per poi rialzarsi quando riappare l'immagine. Il procedimento del video permette di mantenere la luminosità costante senza che ci siano appunto questi cali di luminosità. Spero di essermi spiegato😅 se hai altre domande chiedi pure💪🏻

[@BoggyBogdan]

Great simple video! Helped me with my NU7172, I tried going in the service mode before thinking it would be there but I didn't know this hidden "0000" thing. Much thanks!

[@kascnef]

Did anyone get their settings back to dimming again with the new update?

[@MM-yv5je]

Justin Fencsak yes i thought i was the only one

[@NiftySquares]

You may have to redo the process as the update may have reset the PWM values

[@seanogunbiyi7688]

Justin Fencsak yea just had to reset the values again. I hope this isn’t a common thing with updates. Wondering if I should disconnect my TV from the internet.

[@ELEV8_]

- Does this have any negative effect on the tv itself or something, can doing this shorten the tv’s lifespan or any other negative side effects ?

[@NiftySquares]

I've had these settings for several months with no ill effects. LCD TV's in general are quite robust. I never had an LCD TV or monitor blow out on me.

CmdrGreene thank you for answering and for solving the dimming issue for us.

Jesus Man thanks You!!! Ir was about to return it ...I think the difference between the 7000 and 8000 it's basically this setting ...I really think it is beside extra settings but now it actually looks like and 8000 .

Any reason why after getting to the point where I pressed 0 four times and nothing happens. Does it work on 2020 QLED?

It's very likely the combination is changed or moved. Unfortunately, there is no documentation of the service menu functions.

Thanks a lot, finally dark scenes without this constant flickering. I have an UE65KS8000 SUHD and this auto dimming drove me nuts. On top of a lot of other software issues in this TV. Samsung, get your act together on this software aspect. So many updates, and still it is not functioning as it should. For me Turn off TV > INFO > SETTINGS > MUTE > POWER did the trick to enter the service menu.
