Trying to manually calibrate the display will drive you around in circles - especially when using some 3rd party software that knows nothing about the display [For example some instruct you to set the contrast to 100% which is just about the worst thing you can do to distort the video on this models. Others want you to adjust the black level which again is not a good idea]. I would highly recommend you get the SpectraView II kit so you can automatically calibrate everything and not have to worry about trying to manually set controls.
The over saturated reds are probably the result of:
a - Incorrect or missing monitor profile
b - Application not using the right profile
c - Application not aware of how to color correct for secondary displays (assuming you have the LCD2690 set up as the secondary display) - in which case you should try making it the primary.
Using a wide gamut display next to a standard display will always look "different". Magenta cast compared to your other display can be removed by making a different white point target for the display.
Color shift from one side of the display to the other when looking directly at the screen is not normal. Some green/magenta color shift is normal at larger angles - especially on dark areas of the screen. Contact Tech Support for a replacement unit if the color shift is not corrected with the uniformity correction.
I've included some items from our FAQs that may be of help. They are intended for use with SpectraView, but the concepts will work with other calibration applications:http://www.necdisplay.com/supportcenter/mo...ectraview2/faq/
QUESTION: I’m using two different displays and calibrating both to the same target, however the white points do not match exactly. What can I do to improve this?
ANSWER: This issue can be caused by the different spectral outputs of the two displays causing the human eye to see color differences differently than the color sensor used to calibrate the displays. In this case the numerical measurements from the color sensor are identical on both displays, but they do not visually match. Manually visually matching one display to another can usually avoid this issue. The basic steps to take are as follows:
1. Calibrate both displays.
2. Pick one of the displays to be a reference. Call this display #1.
3. Select display #2 in SpectraView and open the Custom White Point dialog. Use the Visual Match tool to adjust the white color so it visually matches white shown on display #1.
4. When a visual match is achieved, put the sensor over the measurement area and click Measure. This will enter the value that the sensor perceives into the White Point. Save this as a new Target.
5. Recalibrate display #2 with this new Target. From now on always use the respective Target to calibrate each display.
QUESTION: I'm using the Safari web browser, which is supposed to be color managed, however some images appear overly saturated on my wide color gamut display, while others appear normal. What is wrong?
ANSWER: Safari assumes that all images that do not have an embedded ICC profile are unmanaged and are not color managed. Only images that have an ICC profile are corrected. Be sure to embed an ICC profile in each image file if you want to make sure it will appear correctly on Safari, even if the image colorspace is sRGB.
QUESTION: I'm using dual displays, one of which is a wide color gamut. My web browser is color managed, however when I move a browser window to the wide color gamut display, colors are oversaturated. What is going on?
ANSWER: Currently all web browsers that are color managed (e.g. Safari and Firefox 3 [with the color management option enabled]) only use the ICC/ColorSync profile for the primary display for color correction. This means that even if a browser window is moved to the secondary display, it is still (incorrectly) using the color correction for the primary display.
Also Safari assumes that all images that do not have an embedded ICC profile are unmanaged and are not color corrected. Only images that have an ICC profile are corrected. Firefox 3 correctly assumes that all images that do not have an embedded ICC profile are in sRGB colorspace.
I gave it another chance yesterday.
The Uniformity Mode helped, but there was still a noticable difference across the screen no matter what level I put it at. No matter how much manual RGB value calibration I did, I could still not get the colors to look normal. Reds were all tweaked out (mega saturated) and there was still that strange magenta look to the whites. I had to bring the luminance down to 90 to even make the brightness bearable. I still had a headache at the end of the day. The blacks were pretty washed out too.
We're definitely going to return this thing.
