Why are watching HDR in BL of 5? Or more importantly, why are you watching HDR in anything less than 20 BL?

in the evening I openly lower the brightness so that my retina does not burn out from the brightness above 1000 nit.

Where is your Brightness set? For SDR, cannot go over 45. For HDR, 46.

I'd check for you, but going into the SM messes up all the settings.

Ran the YouTube Dead Pixel Repair for Monitors and TV - Revised version, and running at 2.17 hours Wednesday night. Will be interesting to see if different setting results.

Addendum:
PQ looks bolder, brighter and more detailed. Re-calibration had very little changes on 50% Grayscale and lower, but 60% Grayscale to 100% all values were elevated and had to be re-configured down. Like the results after watching a few of the demo videos also on YouTube.

New calibrations after 2 changes

# 1 TV Panel was cleaned up after using a YouTube Dead Pixel Repair (New Revision) 2.17 Hours Video.
# 2 Masciola's SDR Full Screen Patterns now used for calibrating of USB/Apps, and HDMI 1 instead of only 10% window patterns (10 % wasn't a good idea for SDR !)

Note: settings may work for some KS9800 Panels, work with additional tweakings, or not at all.

On YouTube I found a file called “Dead Pixel Repair - for Monitor and TV (2 hour treatment) new version”. Is this the file you used? Is there any risk using this on my tv? Is it just kinda a tuneup that is good to do as the set is over 4 years old now? Thanks.

If it shows a 2 hour and 17 minute running time, and has a multi colored back ground to the title, that's the one. Note: It has all kinds of warnings before it starts. Please abide by the warning. (I actually fell asleep, and ended up with over 4 hours of the video running - no issues I've seen except a cleaner looking PQ.)

(No wonder Pixel Protector went out of business, too many freebies available.)

Did you try it, and did it make improvements ? (You can get the URL from the above YouTube)

2 things.

I'm having trouble using bluetooth headphones with this. It's a Solo Pro headphone set that came with my sons new ipad.
It shows paired and connected but no sound. So in looking around in the menu I stumbled on "retail mode". Out of curiosity I clicked on it. Was wicked bright but I had sound from the headphones. Not sure what to make of that. So I tried a factory reset. Still no sound BUT (2nd thing) I've been noticing a area about the size of a baseball just off center about 1/4 the way down that was noticeably dimmer. I thought it was a area that was collecting dust. After factory reset, It was gone.

What am I missing to make these headphones work?

Current owner of the last/best AmPro on the planet. The mighty 4600HD, and it's still running...better than Barco's, especially southern ones.

In service menu:
go to 'SVC', then 'Other setting', then 'CAL Data restore'
-after this, click return until you are at the first menu and you should now see a 'Advanced' option at the bottom.. hover over it and click '0' four times. this should pop up more options

i recommend being on HDM1, as pressing 0 on another port closes the service menu sometimes.

Who does not understand do not change the settings because it can be dangerous. Many interesting new windows open in all windows and new menu options also appear. This is Ks7000.

There are a couple of interesting settings and since only the European models have changed the backlight algorithm I want to compare to the American models, what can someone do if they take pictures of the windows that open them would greatly help them find the source of the error. He uploaded 56 images showing the Ks7000 settings. I want to find out what is causing the backlight problem because it is very confusing that I have not found any solution for it yet. The 1242 firmware has changed it and since then the TV cannot display as deep a black level as when using the 1241.5 firmware.

Since this is a KS9800 thread, what info can we gain from digging into the service menu in regards to a KS7000?

I have UE65KS9505 this model in Usa UN65KS9800. I just want to know what is causing the algorithm problem which is not working as well as in previous updates. It bothers me that it has changed ...

Going into the SM and checking different areas isnt going to allow you or anyone to see what changed or how to fix what a FW did so pls stop asking ppl to go onto SM and risk bricking their sets. I know you put a lil warning in your post but Samsung doesnt change pq by flicking a switch in the service menu, its deep in coding so dont bother.

I have Bose 700 wireless headphones and getting the connection to work can be very frustrating. Sometimes they work perfectly and other times I have to try a number of workarounds. Turning everything off and on again can help. In the sound menu of the tv it can help to delete the previous headphone connection and refresh. I also find if I have the headphones connected to my iPad as well, the headphones find that connection easy and then the tv connection follows next as an option. Also sometimes I switch between cable and tv input as switching back and forth seems to wake things up. I know you have different headphones, but maybe one of these workarounds might solve your problem.

I did further tests where i examined Hdr tone mapping. Through a native app like youtube the tv can handle 4000nit brightness thanks to excellent tone mapping. Unfortunately, this is no longer known on TV via hdmi up to 2000 nit. Can anyone do a test on this besides me? I watched youtube on ps4 pro - the same Hdr tone mapping brightness test. Here is the link you can watch on TV and via some HDMI device. https://youtu.be/NlAsAuBtmps
I do these tests to improve quality and to have the right product support. I have a friend working for Samsung and he said "of course they're fooling back older models! Consumer society, let's just take the new one!" I’m fighting this and I’m still writing with Korean software developers to fix such deeper bugs that are barely noticed by others but it leads to the need to buy a TV every 2-3 years. That’s why I bought this tv for $ 5,000, but to make it timeless, durable, reliable.

Will check with meter tonight. Note: HDR 100% with 10% window is currently showing as 1690 Nits. Full screen will be less.

I do these tests to improve quality and to have the right product support. I have a friend working for Samsung and he said "of course they're fooling back older models! Consumer society, let's just take the new one!" I’️m fighting this and I’️m still writing with Korean software developers to fix such deeper bugs that are barely noticed by others but it leads to the need to buy a TV every 2-3 years. That’️s why I bought this tv for $ 5,000, but to make it timeless, durable, reliable.
Will check with meter tonight. Note: HDR 100% with 10% window is currently showing as 1690 Nits. Full screen will be less.

Yes the total brightness of the display is around 1400-1600 nit. Thanks to tone mapping, you can show higher values ​​around 1400 1600 nit. The full screen is 550-600 nit. This model was famous for being able to display much higher values ​​even though the max brightness is much lower than 4000nit. It’s a smart software solution to keep high-brightness scenes from burning out.
I live in Hungary and the 65" model cost that much together with taxes.

The TV tone-maps up to 10,000 nits. Confirmed using the TV's media player, an HDMI media player, and using an Ultra Bluray benchmark disc.

I haven't felt that my TV has been downgraded over time.

Also, make sure you are not in Game mode as I think the tone-mapping may be turned off. The theory is that the tone-mapping should be handled by the game renderer.

In game mode, tone mapping performs better, but so does the max 2000 nit that tv can handle. Without Game mode 1000-1500 which it manages and displays it on the tv with ps4 pro.
I am measuring these now and I do not currently understand what is causing this. If the TV has a factory youtube running, you can handle the brightness up to 4000nit while the max tv brightness ranges from 1400-1600. There's the video I linked to, I'm testing with it and when the white light changes to 4000nit it is no longer visible via HDMI. I see the same brightness as at 2000nit. This tv could never handle 10000nit with tone mapping either. Where did you read this or how did you measure it? Maybe you can send some reference video?

i used the standard mode and tested the game mode too! It's not really the point, it's that tone mapping doesn't work properly!

Point being Game mode used for anything other than games dims down after 5 mins or so in HDR and is not accurate for judging tone mapping etc. at all. If something similar is happening in Standard or Movie mode, its only on your set as I don't think anybody else has said anything similar to this on this thread or anywhere else. I would give Samsung a call.
