I just bought a ColorMunki along with Spectraview II 1.1.03 and performed my very first calibration of my 2490wuxi.

Here are my results:


Is my white point Delta E high? How is my black level?

Should I measure my ambient light and turn on autoluminence?

The balck level looks fine to me. The black level of my 2690 Spectraview is slightly higher and I have no problems with it. Personally I would not use the auto luminance feature.

Sorry to bump this really old thread but....WOW how did you get such a good results?

black level 0.19? contrast 759...i'm so confused...this is an amazing results, care to share your settings?

Here are my results, poor comparing yours :(

Have you gone into the settings of SV II software and disabled colorcomp? That would have a big impact on contrast ratio

What do you mean by big impact? does it reduce or increase the contrast?

It lowers it. There is digital manipulation on the white level to make it match across the whole panel and it lowers luminance a bit so your contrast ratio goes down.

Unless you see tinting on whites from one side of the screen to the other, turn it off.

I don't use colocomp, but what i noticed today, after i did one more calibration is this.


1. Whites are now with lower brightness, which make it easier on my eyes then before, when i set intensity to 143, now with 120 its better.

2. I changed D65, to 6500K but now dunno if i imagine things or its real, but it seems like the colors/saturation is higher, does this make any sense?

3. The contrast now is lower, but the black level is higher, @0.19, now with this settings....dunno if i imagine things again, but it looks like the blacks - contrast is/are deeper, but there is some details lost from them, from example in the dark parts of the movies i cant totally see the shadow details as much compared to my old calibration (by old i meant very old like 1 year ago) is this normal, and does the lower intensity/contrast produce this issue?

4. Can i restart to factory defaults, lower the brightness to lets say 20% or maybe 0, and from then start off with calibration but with maximum intensity selected along with this settings: D65+ Gama 2.2,+ 52 steps, in order to achieve highest contrast possible, with less detail lost regarding blacks, but yet get unit good for daily usage because of the manual lower brightness, or maybe the intensity it self will make it very bright even with brightness set so low, is the intensity same thing with brightness?

Thanks again and sorry for bothering.

Agree on the color comp, turn if off. Also on your calibration, you are using only 32 steps, vs the 52, its doing it all automatically, so no reason to not let it grind away, go into tabs and max out the samplings

On my 26inch, I notice with color comp turned on, I get a whining out of the power supply.

I have turned it off, but i don't know what should i do about the possible issues i noted in the previous post...


examples:










I hope you guys got the idea now...

so turn off the Colorcomp from the settings section and enable the 52 steps for the calibration process....if you then run through the calibration process again what do the results come out at then?

Hmm, i cant seem to fine Colorcomp, in which sections it is?

edit: It is turned off.

ok, also turn off auto luminance, either in the software (if it's available) or via the OSD as that seems to be on from your results image above, but may impact measurements. turn that off and then re-run a calibration and post the results here

Ok will try and report back, what does the auto-luminance does? yes its turned on by default for all of my calibaritons i did.

I tough it should be that way? :/

auto luminance controls the intensity of the backlight automatically depending on your ambient lighting conditions. for a calibration you obviously don't want the backlight fluctuating so turn it off before the calibration and measurement i would. can always turn it back on afterwards if you need it

Awesome results! I'm looking into getting a colorimeter for my newly purchased 2490WUXi.

I noticed your monitor has ~12,000 hours on it. I bought mine used and it has ~10,000 hours. I see you're calibrated to 120 cd/m2. What is your brightness set at in the OSD to achieve that level?

Also, have you tried setting the brightness to 100% in the OSD and measuring with the colorimeter to see how much the backlight has dimmed over the 12,000 hours of use? If you could tell me what your monitor's brightness is when you set to 100% in OSD I'd be much obliged.

In this review of the 2490, the maximum brightness when the monitor was new was 360 cd/m2, and after 6500 hours was 322 cd/m2. Typical standard brightness should be around 120 cd/m2 so hopefully we have many years of backlight left.

Thanks.

No i did not tried to set the brightness to 100% becuase its to hard on my eyes that way, but in future, i can test it out for you. If i'm not mistaken when i set the monitor to factory defaults, and used maximum possible intensity, the end result was around 240/ cd/m2, but i'm not sure about this.

Good luck with your monitor.

Thanks for the info. 240 CD/m2 should be plenty of extra brightness to last some years.

You need better colorimeter like i1 display pro and keep the device in the good condition.
The NEC MDVSensor is an Eye One Display 2 that are more accurate than the average Eye One D2.

Is this a joke?
Silica gel packet that comes with 120% of the hardware out there also works sitting in the same drawer or package.

This falls under the theory that the organic filters on these colorimeters deteriorate under humidity over time.

I have an Eye One Display Pro that still thinks my NECs are accurate when I have calibrated using my NEC Eye One D2 sensors so I'm not losing sleep over it ;)

BTW my LCD2490WUXi-BK with 22,000 hours on it (formerly a touch screen) is still also able to put out over 250 cdm/2 max brightness. I think it was used in a warm environment or the touch screen overlay caused heat issues because it's quite yellow and close to 5000K default white color temperature.

not for this model he doesn't. It's an :LCD2490WUXi with standard CCFL backlighting. The NEC sensor is custom designed and optimised for use with these kind of displays and so should offer excellent results. There's also no issue with the fact it's an i1 Display 2 as the backlight is standard gamut CCFL and not wide gamut

i1 Display Pro is far better than i1 display 2 in terms of color accuracy and measure errors.

2490WUXI and 2490WUXI2 are two different gamut monitors. 2490WUXI is native wide gamut display while 2490wuxi2 is native sRGB display.

LCD2490WUXI is actually the wide gamut display.

and here is my native sRGB Gamut P241W



R/G/B Primaries between these two monitors is huge.

You will not be able to calibrate 2490WUXI/2690WUXI/2690WUXI2 under srgb mode with custom brightness level defined by user.

2490WUXI and 2490WUXI2 are two different gamut monitors. 2490WUXI is native wide gamut display while 2490wuxi2 is native sRGB display.
I've tested both against each other and the differences are not large. The sensor from NEC that I have is the original I1D2 with NEC's corrections built in for sRGB and wide gamut screens at that time, and the MDVSensor that psyside has is the newer version for even wider gamut screens, but should be fine.

LCD2490WUXI is actually the wide gamut display.
LCD2690WUXi-BK is wide gamut, the LCD2490WUXi-BK and WUXi2-BK are not.

No it's not. We don't even know if psyside is using factory measurements/corrections with SVII or taking colorimeter measurements (from his settings).

since when? The original LCD2490WUXi was always standard gamut CCFL, and even the replacement LCD2490WUXi2 is standard gamut

see NEC spec: http://www.necdisplay.com/p/desktop -monitors/lcd2490wuxi2-bk
72% NTSC, 75.2% Adobe RGB only
^This.

It's not even like it CAN be wide gamut due to a production problem, as the back-light is simply not wide gamut.

@ Gatehouse,

I did not roll eyes for the sensor quality, but for the wide gamut statement, its not wide gamut dude, no chance, at all....Its a SRGB 72% NTSC unit.

EDIT: Drag already answered, sorry about that.
