Hey guys.

I own a Samsung KS7000 55" 4K HDR TV.

I'm just curious how people go about pro calibrating these so they look the best they possibly can please?

Is they something i need to buy please?

Any help would be grand, thanks!
 
Also interested in this, I have just picked up a KS8000 let me know how you get on with yours. Its my first decent TV so would also like to get the most out of it.

I've being speaking to some calibrator engineers and they are quoting around the £200-£300 range for it to be done.
 
Have you looked for existing calibrations on the web eg for ks8000
Personally do not subscribe to argument that manufacturing differences are so large between examples of the same model such that one calibration for a darkened room will not be good for many (on premium models with 10 point adjustment they are also not typically sourcing panels from multiple manufacturers)

Most of the reviews show very similar colour/gamma errors on the unadjusted examples they use for their reviews, which would support that , but few publish calibrations eg hdtvtest since they also sell such a service

Yeah I have actually already copied those settings haha, cant really say I noticed much difference. I think you would need two side by side to really see it. I am totally happy with the picture, I just think how much better would it be with a proper calibration? Thanks.
 
Kitch9 and signs : if you calibrate the tv yourself with a measuring device how do you solve the problem of setting the white balance and gamma TV settings for example ?

on a Panasonic these are pretty complex - these are my day ones
White Balance 10-Point: 10 R-42/G-35/B0, 20 R-6/G-5/B0, 30 R-6/G0/B-8, 40 R-9/G0/B-11, 50 R-7/G0/B-18, 60 R-13/G0/B-15, 70 R-14/G0/B-14, 80 R-10/G0/B-11, 90 R-15/G0/B-11, 100 R-15/G0/B-19
Colour Management: Red Hue 3, Saturation -5, Luminance 1, Green Hue 0, Saturation -6, Luminance 5, Blue Hue 0, Saturation -5, Luminance 5, Cyan Hue 7, Saturation 1, Luminance 0, Magenta Hue 0, Saturation 1, Luminance -8, Yellow Hue -2, Saturation 0, Luminance -3
Gamma Detailed: 10 1, 20 23, 30 25, 40 24, 50 16, 60 14, 70 8, 80 3, 90 0, 100 0

to optimise these you would need to explain to the software driving the colour measuring device, what the tv setting are, and how they modify the picture, so that it can optimise their settings.

I have done calibration of a computer monitor using an Eye1 device with Argyll software, but a TV with many more settings is another ball game.

I do not see either, what mechanism a 'pro' would use unless there is some interface (usb ?) on the tv to automatically change tv settings.
If this existed then can I buy the mechanism ? (it is a bit like mechanism to access the diagnostic 'port' on a car ecu)

If I were going to have a pro claibration I would want these answers up front before parting with >£200 I believe they charge

This was an article I saw that explained Spyder device, but the software does not appear capable of cailbrating white-balance, gamma

Use a laptop running HCFR. HCFR automatically detects the Colourmunki sensor and takes the readings. The test patterns needed to calibrate grey scale (Thus correcting white balance and see current gamma levels) are on the DVE blu ray I have and I use my blu ray player to display the test patterns. The calibration process is reasonably simple but does take an hour or so.

Basically run a contrast test pattern and adjust contrast to the point there's no visible blending across the higher end steps. Most modern lcds this will be near 100%

Run a brightness pattern and set the brightness so the 2% bar is slighty visible and the -2% bar is invisible.

Run a 100% grey scale pattern and turn on luminosity measuring in HCFR and turn the backlight up or down until its reading 35-40ftl depending on preference, I run 40ftl.

Then measure the grayscale steps in HCFR to find Gamma. I aim for 2.2, if its not at required gamma, adjust gamma settings and test greyscale again, repeat until Gamma is a right level.

The use the instructions I posted to set RGB levels across the entire greyscale range, I set white point at 6500k in HCFR.

Pros don't plug anything into the TV and there's no program that changes the settings automatically, they use a sensor and software and adjust the tv settings manually. In the olden days they used to delve into the service menu to do the fine tweaking but in these days of 10 point colour settings exposed to the user there's no need.

Once that is correct I generally turn the colour setting up a couple of notches, but thats just my personal preference.

Do they actually call themselves engineers? :p

They must be minted charging £200-300 a pop.

Well, the likes of Calman software that the certified people will use are £500+ let alone whatever hardware they have.

Look at the basic X-Rite Spectro. It is about £1,145. http://xritephoto.com/i1photo-pro-2

Or even equipment like this that will cost 2 - 4 thousand as they're accurate versus a puck.

 
OP! not relevant to topic but since you own KS7000, I have two question. Does the YouTube app on the tv allows for 4K60fps option? And if you connect tv with PC, does it accept 1080p @ 120hz signal?
 
Kitch9 Thanks for the detail - yes it does not seem as difficult as I thought

The white Balance on the panasonic and ks7000 both seem to have hierarchical controls coarse and fine - looks a bit tricky

The ks7000 manuals (and my panasonic) do not seem to list all the controls - a bit meh, but articles like this on ks8000 this had some interesting comments on gamma and white-balance menus, basically not using the fine 10 point controls !
(but maybe the guy had been tricked by local dimming which may modify the test pattern after it is initially displayed - I believe)


Gamma was still a bit uneven, but when I tried using the 10 point system to compensate it was ineffective. The controls didn't consistently change the grayscale without very large adjustments, and even then the readings fluctuated from one to the next. As a result I gave up on the 10 point system and stuck with 2. I also didn't adjust the color management system since it was quite accurate to begin with
