Here is an interesting read on HDR from secrets of hometheater. Lately I have seen many posts about how much my new set is better than JS9500. Well "better" is a relative term, but many specifically talk about the imroved brightness level. I am not trying to argue over this, but there is more to it than share brightness (i.e. peak luminance). The question is how close the tv response is to reference monitor most HDR movies are being/were mastered on. Take a look at this graph that shows something quiet interesting. This graph shows how some TV models compare to Sony BVMX300 monitor ($45k msrp). Guess which set came closest to resemble monitor light output performance? So next time someone screams about the brightness level of newly acquired set, proud JS9500 owners can reply, their older set resembles HDR content closer to the way it was intended by the createtors
PS: note that this is something that you cannot "calibrate out" in your display, for those who do not understand how calibration process work.

slummim it with sammy 46 h7150 until 77 oled arrives. be good js9500 owners its been a blast. I started with a 78 hu9000 , proceeded to a 78 js9500 after spots and after 3 panel replacements agreed to a buyback for the js9500. I remember all the good times including the first time I upgraded to the sek3500u and then did the hacks for amazon hdr ... all good times mostly. I will miss the immersion of the curve but am hoping passive 3d on an 77 oled will make me forget quicker. Here is a fun shot of the space the 78 was in. UN46H7150 Pictured.

Does this mean the reference monitor had huge blooming issues too then??

Or hdr clipping. Technically, the 2015 oled tvs would also be more in line with those oled reference monitors too. Some of those hdr reference monitors are only like 300 nits or so.

Now i'm really pissed. The screen went black again for one sec. when watching blu-ray. Audio wasn't affected as usual. I thought i got rid of this issue long ago. Seems to be built-in to this freaking tv

Please provide some links to measurements that support your statement. 300 nits technically can not be HDR monitor, even less Reference monitor. 2015 OLED(as well as later rivals) certainly do not track Sony BVMX300 reference monitor, not even close but the shape of the curve is definitely more appropriate vs much brighter Z9.
Rtings doesn't measure as many screen size variances but their measurements are still useful to make some conclusions look for yourself:
2015:
EF9500, it is not very bright.

2016 models are better, but really far in terms of peak brightness capability of reference monitor.
C6 review
E6 review
B6 review
Interestingly enough the cheapest model offers brighter image.

BTW blooming never bothered me, perhaps that explained by the fact that 78" set has 240 dimming zones vs 150 on 65", so technically they are not the same set. I do see blooming only when I move off center about 25 or 30 degrees which is a big no no for VA panel.
And yes JS9500 doesn't not have the OLED image retention either. You can watch anything without worrying about IRE 100 channel logos, play games or whatever you feel like doing, including HDR content. I could list other problems OLED have but what is the point? Instead I realize pros and cons each technology has to offer and care less about defending my purchase. There is no perfect display even Sony BVMX300 is not.

On another subject:
Interesting Apple's response to OLED burn in concerns. "Apple also recommends using Auto-Brightness, shorter Auto-Lock periods, and running the latest software update to prolong the life of the OLED display. Finally, Apple recommends against showing static images at full brightness for extended periods of time with Super Retina display on iPhone X:" No static images on $1300 phone??? They expect me to turn the screen brightness down when I am outside?

I was kind of being sarcastic.. But since you asked..

 400 nit 24" hdr 4k grading monitor : Canon DP-V2410 4K  price tag: $17,999

1000 nit 4k HDR 30" Sony Bvm x300, price tag: $30,000 (this monitor tho I believe is more commonly used and also newer)

The monitor doesn't need to be as bright as its grading for. Just like they can use the 1000 nit Sony for Dolby Vision grading up to 4000 nits.

Forum member Tom Roper even used his 500 nit Js8500 a couple years back to grade his 1000 nit hdr videos. (tho I don't think he uses it anymore for grading).

Seems like your insinuating that I'm defending oled which I'm not, it was sarcasm. I have a Samsung KS9800. I would never buy an OLED at current prices because of the trending IR/BI issues. But when it comes to cell phones, I'm never going back to lcd

It was nice to see the JS9500's compliant curve. I've always felt mine is an outstanding set.

But, however inappropriate you may think the Z9's curve may be; it's an amazing display for HDR. Granted, although it peaks at 10% (1800+ nits), it does drop significantly down to 1%. However, even after that significant drop, it still has more available at 1% (1200 nits) than any other set; and will do around 800 nits on a full screen. When you combine those nit levels with 800+ FALD zones on the 75" display, it's a beast for HDR.

I was asking for measurements (graph preferrably). More specifically I wanted to see how 2015 OLED track "Reference" monitor as you stated. Now I read you were being sarcastic, so I don't follow your line of thought.
Sony BVM X300 is the monitor I was referring in my original post that was used for comparison reason. Not sure why you mentioned it. Perhaps you are being sarcastic again?
I get your point that one can grade video on whatever he feels like. Shoot one can do it on the cellular phone, but this has nothing to do with my original post. Once again I am not looking for an argument to discuss but rather learn something new.
Canon DP-V2410 4K - if you have seen measurements on this device (similar to those I have provided) it would be interesting to see. The same applies to OLEDs for whatever year. Note I am not being sacrastic.

Z9 it s great set. I am not trying to put it down. It is just scientifically less accurate in this particular case, but it is nowhere near as bad as Vizios.
In fact 99% of population can care less about this. TVs are ran in torch mode in the stores as that is what sells them.

Has anyone tried xbox one x with this tv? I wonder how it will be to switch between HDR and non HDR games. Do I have to turn off UHD color, turn down gamma, dynamic contrast etc. every time I play a game that does not support hdr?

And I would have loved to see an update so I don't have to turn down backlight from 20 every time I want to watch HDR content......

I'm not sure about games, but this is exactly what I do for HDR movies; in fact, I dedicated two inputs for HDR settings/material only (one for UHD disk player, one for Chromecast Ultra).

BL=20 is required in order for this TV to apply its tone-mapping algorithm correctly for the HDR metadata it receives when playing HDR content; this is why it auto-switches to this setting for HDR.

It's been a slice @nc88keyz and I have enjoyed your company and continued presence on the HU thread.

I think we all benefited that the HU + SEK shares the same firmware as the JS series so we could share ideas.

i can be dry and abrasive at times but there is a certain expectation when you purchase a display that is more than a fine used car. Maybe that's just me, but likewise Musician. It has been a blast.

Hello everyone.
My JS9500 has developed a brown spot due to the failure of one of the LEDs. Five months ago the warranty expired and SAMSUNG does not take over the repair. Do you know if there is any way to change the faulty led?

Nope. It requires a complete panel change.

You'd have to ask a TV repairman who might know if he's using a refurbished panel or not.

It is terrible to spend so much money on the JS9500 and to break it with 29 months. I will never buy anything samsung, or mobile phones or washing machines, nothing samsung.

Ironically I have one of those lol. A set actually and Samsung’s process about fixing the issue is terrible. I’m moving away from their products all together. Their phones are on their final straw as welll...seems quality has gone down across the board. Although I can’t complain much about my s8+. The tv and other products I’m done with for now...

Judging by the size of the brown spots, I'm curious if when 1 led fails, it actually affects all 4 in that zone. 4 LEDs per zone, 600 total LEDs on the 65" model.

My rationale is, I'm thinking display reverts to backlit panel with FALD disabled? Could be failed logic though; likely, it's not two sets in one but failed panel.

I'm sure others have tried this too but I just didn't find result mentioned or confirmed. ??

On the Samsung washer subject, I had one ordered way back but cancelled after reading reviews and tried LG instead. Lowe's seemed to think the LG needed leveling and just installed it. Crazy thing must have shook itself silly. I had them replace it and level it. 4 years without issue...

Just replaced a refrigerator with LG; decided to give it a chance for its reduced and relatively low price but reviews say the Inverter Linear Compressor has longevity concerns. Some have had multiple compressor replacements. Where has product reliability gone?

The brown spot does not disappear by activating or deactivating Smart LED

Has anyone tried the Pixel Protector Washes to see if they will revive the brown spots?

Have not been able to try this since I don't have any brown spots on my HU9000 + SEK-3500U in JS Mod mode.
The Pixel Protector Washes do enhance my sharpness and colour on my set if done at least once a year.

Looks like about 1/3rd of users like it and 2/3rd's do not.

Do you suppose a temperature gun might help:

give some advance notice of LED burnouts behind your screen.
Art
# 1 - The calibration part of this disc is more for European sets. Did not find it any where as good as the Spears & Munsil Blu-ray II for NA sets. (Too bright)
# 2 - I don't let my sets get far enough in to have burn in, but I've yet to see burn in on any of my LCD/LED sets anyways.
# 3 - Brown spots are caused by what? Would a good kick in the pants wake them up? Like mentioned, can't test, when I don't have them.
# 4 - Pixel Protector Washes are for properly working panels, or partially disabled panels, where the washes will rejuvenate them. (Despite some claims for badly burnt in screens that have NO hope!)
# 5 - If Members know there is a possibility of burn in on the set they have, why are they not taking more precautions? If a Member knows his wife is going to run the news all day for back ground noise, and have the banner running all that time across the screen, why not show her the Screen Off feature and listen. If something comes on that's interesting, now turn the screen back On, watch, and then back Off when finished?

Note: The Blu-ray version is superior to the DVD version shown in the reviews.

The brown spots are produced by a fault in the LEDs, it is also possible an error in the control of the backlight.

panels no. 2 and 3. we're both brand new stock for a 78js9500 in my account. while they didnt have brown spots one had very visible banding and the other had a zone issue it appeared on lower left area a lot of bleeding of light on letterbox scenes. keep in mind was an half panel.

This is my thought exactly, I have seen so many Samsung products around me die very quickly.

I spent about 4K on the 65" version of this TV and it made it 14 months (brown spot)!

Also I thought brown spots were due to a burn in the panel where the LED sits?

Never again...
