Spectraview 2 works with EU multisyncs and you can perform a LUT calibratiion with this software. Its not legal in most countries to get the serial number from a friend. You need to purchase Spectraview 2 from him, since only one of you can use the licence and thats the owner of it. Basically its the serial number you purchase, since the media can be downloaded afterwards.

Spectraview 2 ONLY does LUT calibration. It cannot calibrate the sRGB preset for you and I suspect that the lut loader isn't compatible with profiles created by other calibration programs. Makes it a bit more pain if you switch between the preset and your lut calibration profiles. Spectraview profiler can calibrate in many ways and you can change calibration "on the fly". Using Spectraview 2 makes it a bit hard to use the presets, since the LUT loader always loads the previous calibration upon each restart into the GFX LUT. This means you might have to disable the lut loader, manually change into the sRGB profile of your choice through the windows color manager, and then restart windows. There might be faster methods, like if you have the Spyder profile chooser.

Unfortunately, NEC changed the firmware so that the method used to make EU multisyncs (as well as US multisyncs) report themselves as SV screens are useless on later revisions. I do know about the method, since I was the one who first presented it on internet.

Spectraview profiler is actually a NEC ordered special version of BasicColor 4x, while Spectraview 2 is made by NEC themselves.

Thanks for your UNVALUABLE help, Tamlin

Sorry to bother you again...
Also I've read that calibrating the NEC to the sRGB Gamma Curve instead the L* Curve can decrease the saturation a bit and the result is better than the fixed sRGB preset mode. Do you know something about this? And if yes, can you explain in detail for dummies? (I have no idea about monitor calibration)

I'll try to simplify it a bit if you don't have previous knowledge about this. Its hard though.

The gamma curve on a screen is actually a tonal response curve. You have probably seen pictures like this:
http://en.wikipedia.org/wiki/Image:Gamma06_600.png

The point at Origo (0) represent the darkest shades, while the point at top right represents the lightest. A color on the screen (and in the cones of your eyes) are build up by 3 primary colors: Red, Green and Blue.

On an 8-bit screen, each primary color have a range of 0-255. 0.0.0. is black, while 255.255.255 is white. The numbers mean that Red=0, Blue=0 and Green=0 when producing black. A shade is always made up by those 3 primaries on a screen.

If to think about black to white (greyscale), it goes in steps for each gradient: 0.0.0, 1.1.1, 2.2.2 etc. If you adjust the tonal response curve (gamma curve) to be a flat line you alter the steppings so that 0.0.0, 1.1.1, 2.2.2 etc. will show the same shade. effectively, you remove the steppings.

The L star is created to give a perceptual even stepping, so each gradient have an equal step. Its the one recommended to use when doing editing these days.

sRGB has a different curve, close to 2.2 (but not exactly the same).

The gamut value is a different story. Even though you can change the gamma to 2.6 producing strongly saturated colors, or down to 1.8 producing more washed out colors, it will not alter the gamut I'm afraid. You are just altering the tonal response.

Hi Tamlin:

Is it possible a guided tutorial with screenshots in order to calibrate the NEC to the sRGB gamma curve? For example, a calibration you have already done... Please, skip the technical part and explain in detail the practical part with SpectraView Profiler or SpectraView II... My only interest is to work in the sRGB mode as closely as we can...

Thanks very much in advance Take the time you need, I'm not in a hurry...

There is no need really for a tutorial here. The sRGB gamma curve is a preset in the calibration program. You just select it.

Okey, thanks... When I will purchase the NEC I'll try to calibrate it in native mode to the sRGB gamma curve... since another poster of [H] claims he has achieved betters results than in the fixed sRGB mode... If I would have any problem/doubt, I will contact you again. I have a Monaco OPTIX Pro calibrator (nowadays superseded by i1 Display)... I hope this works.

Thanks again. Your help is very appreciated. Superb forum and superb support too!

Hi Tamlin,

I have a NEC 1990SXi, I activated in the advanced menu the spectraview settings ON.

With Basiccolor Display 4.0.2 it's impossible to activate the hardware calibration (the option is grayed...).

The link to Spectraview Profiler http://www.spectraview.nec-mitsubishi.com/ don't work.

Can you help me? Sorry for my English...

Thats bloody INSANE.

Here's a link that works:

Thanks Tamlin,

Hardware calibration works OK now with Spectravier Profeiler, and with Basiccolor (are the same soft).

I have a little question, I have two monitors, the main monitor, the best is the NEC 1990 SXi and a hold CRT monitor (Mitsubishi Diamond PLus 92). I profiled the two monitors and I don't know if Basiccolor or Spectravie Profiler LUT loader, load the two profiles to the two monitors. I turned off the LUT loader on the windows star and I use the color Control Panel Applet. With hardware calibration for 1990SXi this is correct?. LUT loader from Basiccolor 4.1.9 works OK with two monitors?. Whats the correct optino?.

Thanks a lot.

You're welcome!

Neither ToastyX @ [H] nor I have found a way to hardware/LUT calibrate the screen to sRGB. Using sRGB curve as target won't change that. But, it doesn't matter as long as you don't need something to be as colorimetric as possible outside of programs which isn't coloraware. Having things colorimetrical accurate only matters in a workflow. Outside of a workflow its more important with the personal preferences of what's estetically pleasing.

The sRGB mode is more colorimetrical accurate, but even I prefer using wide gamut on most sRGB content.

Within color aware programs like Photoshop, you can select sRGB as workspace and use the 2690WUXi as it was a sRGB screen anyway (and have an option to view the wider aRGB upon selection within the program.) Since it operates with virtual colorspace, it won't represent much of a problem using the sRGB gamma curve for your work.

You can see what works best out for you and don't hesitate to ask if you have more questions.

Your're welcome! Happy to see you managed to get it work.

Spectraview profiler have multiple monitor support, so you don't have to use the control panel applet. It sets the appropriate profile as default and you can use the control panel applet to see if did that. Within Spectraview profiler, you can select "file -> open" for a new profile to use and it will set it as default "on the fly". Open control panel applet and check if it changed there too if you are uncertain. If you use XP, you might need to update the color panel applet if you haven't done that already. The first one didn't support multiple monitors, but the update did.

Tamlin,

Te only way to load two profiles for each monitor (form me) is with ControlPanel Applet (last version). If I load the profile with File->open option form spectraview Profiler or Basiccolor, the profile is show in the two basiccolor or spactraview windows, and only a monitor profile is changed, the firts one, the second not visible changes are made. But with Control Panel Applet all is OK.

Then I put in the windos startup Wincolor.exe /L for load the defaults profiles in each monitor.

I don't understand why LUTLoader.exe can't load two profiles for each monitor. But Control Panel Applets woks ok for me....

Hi Tamlin.. This NEC shows text mode and the XP logo screen with 1920x1200px. No interpolation options are available with native resolution. I think the XP logo screen is 640x480px size... but what about text mode? My NEC 20WGX2 shows text mode as 720x400px and interpolation options are available.

The monitor is connected via a DVI-D cable to the graphics card.

Is this a issue?

Thanks

Sorry for late reply again.

osemabcn:
Spectraview profiler have dual montor support, but I only tested it with two 2690wuxi next to each other. It worked.

If it works for you with control panel applet, then everything is ok. With a hardware (LUT) calibrated screen, the adjustments are already made in the screen itself.

HU: I think its the GFX card. I can't remember having any problems scaling with the ATI 3870X2, but I have a Nvidia 7800GT card in now and have the same issue as you do. Both with the DVI-I and the DVI-D. Haven't tried with the VGA yet via the computer, but scaling works perfectly when I connected a DVD player I have though VGA.
