My fiancée’s catering website doesn’t look right on my NC10, compared to my calibrated Eizo LCD. I’d intended for it to be in subtle shades of olive green, but on my NC10 it came out much more of a neutral grey. So I’ve calibrated my NC10 screen and it gives a much better result, to my mind.
So I measured from my NC10 with the screen set to three bars brightness, using a gretagmacbeth eye-one display 2. Set for a white point of 6500K with a gamma of 2.2
I’ve put the calibrated icc profile and some basic instructions on my webspace http://www.taphouse.eu/nc10/
January 27, 2009 at 9:12 am #181448TCMuffinMemberThank you for this, it never crossed my mind to calibrate my display, but I also have a GretagMacbeth eye-one display and will try this.
January 27, 2009 at 9:16 am #181434jezMemberlooks intetesting, can you explain what this is all about though as I have no idea what an icc profile is! So as per your page, if I upload that profile I should see more “realistic” colours?
And in theory, assuming our screens are the same, it should help all NC10 owners?
I like the look of that site by the way, very clear, and a professional yet accessible feel to it. Good job.

[/quote1233051545]I had to set the screen resolution to 1024 x 768 to use the software, then scroll about. It’s a bit of a pain to get the sensor on the colour patches and still press the buttons, but I managed after a couple of tries. Don’t forget to turn off auto dimming on the LCD.

[/quote1233051533]Yes, this ought to help all NC10 owners – assuming our screens are similar.
So to explain a little bit more about the colour calibaration: The eye-one sits on the screen and can measure colour. It comes with software that outputs many colours to the screen and then measures what colour actually got displayed. This then calculates how best to correct the signal the graphics card sends to the display, to make the colour nearer what should have been displayed. It stores these results in an icc file – so basically consider this a list of corrections to make your colour more accurate.

January 27, 2009 at 12:20 pm #181461sibereMemberHi all!
Found another icc profile for colour calibration of my NC10 here:
http://img1.focus-numerique.com/focus/profils-LCD/Samsung%20NC10.iccIt has been done with a “LaCie Blue Eye Pro” and I find it very good a far away from the blueish NC10 we all have.
Give it a try !January 27, 2009 at 2:56 pm #181450avserviceMemberThese devices are called Color Spectrum Analyzers.
The idea is mostly to be able to calibrate the display to some known color gamut or spectrum so that it can be used for duplication from machine to machine and to print and broadcast media all with the colors staying true.They are also used to set the display to track a certain color temperature spectrum to faithfully reproduce Video when played back.
I use one to calibrate large screen displays,mostly projected images but mine is way too large to try on a laptop display.
Great observations and tip though.

[/quote1233073956]The link isn’t working for me it just loads a txt code page!
January 27, 2009 at 4:42 pm #181440AlfiharParticipant@Jonny Blond: Both links work fine for me, if it’s the link for the icc file you may need to right click and choose download.
I’m torn between leaving my screen as it is, with it’s blue tint. Or whether to use the calibrated profile and have a slightly yellow tint (mostly because I’m used to the blue). Especially as I’m not using my NC10 for any colour sensitive work.
January 27, 2009 at 5:35 pm #181453Jonny BlondMemberSave as worked. Thanks. but its overly cool ct ( yellow ) im going to use the calibrated one on the other post.
on a related note has any one found a way to calibrate or change the video overlay setting ( for tv & vid etc ) its a little dark and needs some contrast. i have done it on xp through the display settings, but can’t find them in win7
January 27, 2009 at 6:22 pm #181462sibereMemberI’ve tried the other ICC profile too… and I’m really supprised how different it is from the one I use. Aren’t those “Color Spectrum Analyzers” suppose to give us a profile to get “true” colors? So why are they so different? I dunno witch of the two gives me the real true color…
January 27, 2009 at 6:37 pm #181441AlfiharParticipantThere are variances between panels even from the same model laptop/screen.
For example I have two identical screens (although one is a bit older than the other) connected to my desktop computer, one is rather yellow while the other is a lot cooler and slightly blue tinged, before I created individual colour profiles for them so their colours are closer.
January 27, 2009 at 7:17 pm #181455tocasaMemberSo I agree – the profile that sibere posted gives a less yellow result than mine. I’m guessing here, but it feels halfway between my calibration and the samsung default.
One reason for the difference could be the white point. I calibrated mine to 6500K, which is meant to be a standard for screen. But for a long time, I prefered 9300K, which gives a bluer white. I’ll try recalibrating my screen to that standard… results here soon!

[/quote1233083407]Depends on what you mean by “true” colours… There isn’t a display technology available that can display all the colours the human eye can percieve. All displays have limitations and must approximate – they do this in different ways and so we get different colours.
January 27, 2009 at 7:36 pm #181451avserviceMemberThe 6500K color temp is really a video standard meant to track the color of studio lights used when shooting film and TV.
The use of other temp. curves for computers may be somewhat arbitrary,I am not aware that an absolute standard exists.In the computer and printing world I think the defaults are the Adobe RGB colorspace and Pantone respectively.
I would think the computer calibration software lets you select one of these two and others but even then the wide tolerance between non-pro devices will mean wide ranging results.

[/quote1233085244]sRGB is the low-end monitor “standard” as far as I know. sRGB and adobe RGB are based on the D65 illuminant (~6500K).
I compared my icc profile and the one from the other thread to the sRGB standard using a program I have available at work. Neither managed to cover the full sRGB gamut (i.e. the range of colours that the display can make). So, even calibrated, the NC10 is not going to suitable for serious photo editing. But this isn’t really a surprise to me – there are very few laptops with decent displays for photo editing.
Setting 9300K as the white point isn’t very nice… probably more blue than default.
