Samsung Series 7 Chronos (NP700Z4 & NP700Z5) and ICC profile

Honestly, as far as I can tell, changing the color setting in Easy Settings completely overrides any settings applied by an ICC profile. For example:

1. set to ICC profile, then change Easy Settings from no effect to standard
2. set to different ICC profile, reset Easy Settings to no effect, then set to standard again

In 1 and 2, if I compare how my screen looks after setting the ICC profile, I think they look pretty different. However, after setting Easy Settings to standard in both 1 and 2, my screen looks exactly the same, regardless of the ICC profile.

I'm pretty sure in order to actually use the calibration settings from an ICC profile you have to disable igfxpers.exe (mentioned in post #11 of this thread). Notably, if you do disable igfxpers.exe, changing the display color in Easy Settings does absolutely nothing.

Just my two cents, anyway.

 

There was no "Samsung Series 7.icm" in the COLOR directory, several other icm' s though.
Added the downloaded one and made it default, then chose SHARP.
Is that all?
Also renamed igfxpers.exe to .BAK.

 

Download the ICC file, then right click to that file and choose install. After that, it will appear on the list. Also, you don't need to rename the file. Just make sure it cannot run at startup by using msconfig and disable it.

 

What Easy Settings display color setting was active during the screen calibration procedure which generated this ICM file ?

Do I have to use the same color setting as the author of the ICM file to get my screen truely callibrated ?

 

Use the Sharp Color setting in Easy Settings.

 

Sharp Color setting looks good on the desktop, but it fails to present a decent calibration on these test patterns: Single-page version.
Colors are clearly over saturated in the contrast test, and as a result pictures lose detail if there are objects with strong colors.

I ended up using my custom adjustments in Intel Graphics and Media Control Panel as follows:

Display -> Color Enhancement -> Color

Red -> Brightness=0, Contrast=48, Gamma=1.0
Green -> Brightness=0, Contrast=50, Gamma=1.0
Blue -> Brightness=0, Contrast=45, Gamma=0.8

No ICM file is loaded, and igfxpers.exe must be running.

The above settings eliminated the bluish tint that seems to be intrinsic to my screen. I also noticed in the test patterns that the gamma adjustment is very sensitive to vertical viewing angle. You must be looking straight to the screen in order to confirm the adjustments.

My computer model is NP700Z4A-SD1BR (I live in Brazil).

 

Well it also depends on each person feel. Nothing is perfect. To me, I really don't if I choose other mode rather than Sharp, but Sharp looks better and brighter with the ICC profile.

 

Is there anywhere else to get these ICC profiles given Megaupload is not currently available?

 

my laptop starts the OS with one colour profile and 15 or 20 seconds later changes... does this happens with some of you?

 

Yes it does. The tweak I've found is to copy paste the Intel shortcuts in the Startup folder.

If you don't understand what I mean, tell me ;-)

 

I've implemented the .icc profile with Samsung's "sharp" setting and it fits my needs and actually looks like a really nice screen now. Is this the intended use of the profile? Regardless, I'm happy, but I was wondering if there was another method I could try to maybe find something I like more?

Coming from a desktop with a fairly decent monitor to the original screen on the Chronos was jarring at first (got used to it quickly), but I am much more satisfied now.

 

The new link is Samsung Series 7.icm

I just found it back on page 4.

Maybe SOMEONE can update the OP?

EDIT: ICC profile added as attachment!

 

I've added the new link to this post. However, it may be better to zip up the profile and attach it to a post here.

Muchas gracias!

EDIT: John, can you also point a link to the attachment in my post above (#62)?

 

does this work with windows 8 too??

 

After checking out the ICC profile, I agree with the original poster... it's nice but not perfect. Apart from what he states it is also a bit on the sepia side (dark brownish).
The link to the calibration pages is great, indeed quite valuable to get to the ultimate adjustments from any panel.
After playing for a long time with the video card settings and the testing pages I come to the conclusion that you cannot arrive at an optimal setting for this panel. This LCD panel apparently (from what is mentioned in the calibration page) just does not seem to arrive at the optimal sRGB values or gamma settings (of 2.2 value per the industry standard - as stated in the page - go to the gamma calibration test page to verify this). Even so, one can get very pleasing image results with different settings that will depend on the application. After trying out settings for quite a few days I have arrived at the following. You can download the enclose zip file with the profiles and double clic on each individual .reg file to register the values of each profile. They should appear in the intel graphics and media control panel.
Please be sure to disable any ICC profile so that it does not interfere with these settings (just un-checking the box in profile will do). Also, the display configuration in Easy Settings should be in "no effect".
From now on all color changes should be made from the intel console. I've tested this way and color changes are enforced on both the intel and ati graphics. For gaming I have not made a settings as graphics can be so much different between games, they also mix in cinematics, so probably one of the movie settings will give good results, but please do use these settings as a starting point to make your own game color profile.
In case you'd like to enter the values manually, here they are:


*PHOTO RETOUCH (max shades and color tones visible, most accurate settings according to the test page):

BRIGHTNESS 3
CONTRAST 46
GAMMA 0.8
HUE 0
SAT -1


*DESKTOP USE - (crisper text, whiter whites, livelier colors):

BRIGHTNESS 0
CONTRAST 50
GAMMA 0.9
HUE 3
SAT -2


*MOVIES-1 (best overall - higher detail vs movies2):

BRIGHTNESS -6
CONTRAST 50
GAMMA 1.0
HUE 0
SAT 3

*MOVIES-2 (sharper, but sacrifices shades):

BRIGHTNESS -9
CONTRAST 43
GAMMA 1.29
HUE 0
SATURATION 6


For the Photo Retouch profile I really did not want to go into individual color curve calibration as I do not have the proper equipment. If you have some test equipment or means to achieve a better color fidelity, please do use those as a starting point. Would love to see the results. Although I believe it is point-less to try it since the lcd seems to be out of industry specs regarding gamma.

I hope this proves valuable. You can try switching between the settings testing out the differences. Just for fun, try loading the Prometheus trailer in HD... interesting color shades and specially lots of dark shades. Compare with ICC too by checking and unchecking its setting while video is paused or running:
Prometheus - Official Full HD Trailer - YouTube

also, nice clip of wild life in HD:
Nature & Animals 2 (1080p HD) - YouTube

On the lcd test page at
LCD monitor test images
check the contrast, black level, white saturation, gradient, and sub pixel layout tests.
Forget thinkering with the sharpness and gamma calibration test pages, you will see the lcd fails to deliver there.
On my 7year old sony vaio vgn-a190, although it has lost luminance... the test results are practically perfect, with gamma within the specified industry ranges, and the sharpness "blend" effect clearly visible. As I said, if you compare those2 tests, specially the gamma test page you will see the series 7 lcd fails to deliver there. I guess this is why it is so hard to arrive at an "optimal" setting that would satisfy all applications.

I hope some of you will find these settings useful, please feel free to comment/ contribute.

 

There may be a way with using the Intel Graphics settings for Media (Graphics properties-> Media-> Color Enhancement -> Standard Color Correction, set to "Driver Settings" and then customize it how you want it). I don't know how this differs from the Display -> Color Enhancement settings in there. but maybe someone can explain the difference. It seems we should be aware of both. Keep in mind, this would require you to use Intel Graphics to do your tweaking, instead of the ICC profile settings. Most people seem to be doing the opposite, disabling the Intel settings, but some people are relying on the Intel settings, instead.

 

I'm wondering the same thing myself -- I assume it comes down to what counts as "media"...videos for sure, but I can't say for certain that games are treated the same way. I'm trying to research it right now but can't find ANYTHING!

Hi
Can anyone tell me the Color Enhancement Settings Values in Intel Graphics and Media Control Panel when display is set to Sharp in Samsung Easy Settings (the version which OP might have used)?
Is it this?

Red -> Brightness=-13, Contrast=51, Gamma=0.92
Green -> Brightness=-12, Contrast=51, Gamma=0.98
Blue -> Brightness=-11, Contrast=49, Gamma=0.9

Thanks
