I need a dedicated sRGB display for my workflow. I have read that, in theory, wide color gamut displays can introduce banding because there is a larger color difference between each video level. Since my video card and software don’t support 10 bit video, would it be better to get a display with an sRGB gamut LCD panel?
 
 
The color gamut conversion to sRGB is done within the display to a high bit depth, even if the video input is only 8 bits. Therefore color banding is not an issue.

My prints don’t match what I am seeing in Photoshop on my display. What could be wrong?
 
 
This is a very difficult question to answer given the huge number of variables involved. Some general hints are given below:
1) Confirm that your display monitor and printer profiles are correctly installed and associated.
2) Confirm that Photoshop or other application being used is configured to use these profiles. You should never use the display monitor’s ICC/ColorSync profile as the color workspace.
3) Confirm that you are using the correct printer profile for your particular printer, and the type of paper being used. Be aware that print colors change drastically depending on the paper being used, so it is vital to obtain and use the correct printer profile for the combination of printer, inks and paper.
4) If possible use a printer profiling package to generate an accurate profile of your printer and paper combination.
5) Most inkjet prints will change color as they dry. Allow sufficient time for drying before evaluating color.
6) Make sure that any colors you are evaluating are not either outside of the display or the printer’s color gamut.
7) Make sure that you are using Photoshop or other application correctly in order to do a "proof colors". Note that most applications no not show a "printer simulation" or "softproof" by default and these modes must be specifically selected. See the documentation for your imaging application and other resources for more information on this complex topic.
8) Make sure that the printer’s control panel is correctly configured when printing. In some cases it may be necessary to disable the color management in the printer driver. See the documentation for your printer and other resources for more information on this complex topic.
9) Review the lighting conditions being used to evaluate your prints. The lighting should be consistent and of known characteristics. The use of a lightbox is highly recommended. The area surrounding your workspace should ideally be neutral in color and relatively dark to avoid influencing visual judgment. Daylight should not be used to evaluate color if possible because of the huge variation in color during the day.
10) Depending on the lighting conditions, it may be necessary to choose a different Intensity and/or White Point when calibrating the display using SpectraView.
Expand
What do I do if my monitor’s power light is orange, but I don’t see anything on my monitor?
 
 
This usually means the monitor isn’t receiving a signal from your video card. Check that everything is properly connected. If you still do not see an image, reboot the system. If this continues after a reboot, call NEC Service & Support at 1-800-632-4662. (You can also verify that your monitor is not causing the problem by trying the monitor on a different system.)
Expand
Why do images and fonts on my LCD look choppy or blurry?
 
 
Your monitor resolution is probably not set correctly. Check your display settings, or refer to your user manual for auto adjustments.

The native resolution of a 15" LCD panel is 1024x768. Lower resolutions result in choppy-looking text and bold lines. To fix the problem, change the resolution the recommended 1024x768 setting.

The resolution of 18" and 21" LCD panels is 1280x1024. Resolutions lower than the pixel count of the LCD module result in choppy-looking text and bold lines. To fix the problem, change the resolution to the recommended 1280x1024 @ 60 Hz setting.

Why does my monitor show as “Plug and Play" in Windows XP?
 
 
This may mean you don’t have the correct drivers installed. Visit the Support & Service section of our site to download the right driver, or use the NEC Monitor Installer.
Expand
Why is my monitor clicking?
 
 
Clicking normally happens when a video graphics driver executes high-resolution programs. It’s an expected function of the monitor’s relays, and does not mean there is a problem with the monitor.

What is the Auto Luminance feature and when would I want to use it?
 
 

The Auto Luminance feature (available on the LCD2490WUXi, LCD2490WUXi2, LCD2690WUXi, LCD2690WUXi2 and LCD3090WQXi) uses an internal sensor to constantly measure the luminance of the CCFL backlight used to illuminate the LCD panel and generate an image. These measurements are used to regulate the luminance of the backlight so it remains as constant as possible despite changes due to temperature variations and normal aging of the display.

Using the Auto Luminance feature means that the display won’t need to be calibrated as often and that it will become stable in luminance sooner after powering on. Using this feature will increase the calibration time slightly, and may have a very slight impact on the contrast ratio of the display when calibrated. The Auto Luminance will not be used if the Target setting is near to or above the maximum possible Intensity of the display, or with Targets with Maximum Possible Intensity selected.

Expand
What models have an IPS panel?
 
 
The NEC Professional 90 Series models with the letter "i" in the model use IPS panels.
Expand
What is NEC’s pixel policy?
 
 
All of our display products meet ISO 13406-2 Class 2 specifications, which allow for a certain number of "pixel faults" based on the total pixels in the monitor. (Pixel faults include whole pixels or sub-pixels going dark, staying permanently lit or flashing.)
Expand
The power indicator LED on the display is too bright and distracting. Can it be turned off?
 
 
The brightness and color of the LED can be controlled for most models of display using the controls in the Monitor Settings dialog available on the Tools menu in SpectraView or for the MultiSync PA Series through Settings panel of the MultiProfiler tool.
Expand
What is DDC/CI?
 
 
Display Data Channel/Command Interface is a two-way communication link between the video graphics adapter and the display monitor. It uses the normal video signal cable, so no extra cables are necessary. All adjustments to the monitor settings are done automatically using this communications link.
Expand
What can I use to clean my LCD screen?
 
 
Use a lint-free, microfiber cloth. If the dirt won’t come off, add rubbing alcohol to the cloth and try again. Never use any cleaning solution or glass cleaner on your monitor.
Expand
What is HDMI?
 
 
High-Definition Multimedia Interface is an interface standard used for audiovisual equipment such as HDTV and home theater systems. With 19 wires wrapped in a single cable that resembles a USB wire, HDMI is able to carry more than twice the bandwidth needed to transmit multi-channel audio and video. HDMI fully preserves the source signal, delivering the sharpest, richest picture possible.

As a rule, HDMI cables should not run longer than 15 feet (5 meters), or degradation of the signal could occur.
Expand
Where can I find documentation on RS232 codes?
 
 
RS232 external code commands can be found under the Products section, under the Downloads link.
Expand
What is sRGB?
 
 
sRGB is a standard RGB (Red Green Blue) color space created cooperatively by HP and Microsoft for use on monitors, printers, and the Internet.

sRGB uses the ITU-R BT.709-5 primaries, the same as are used in studio monitors and HDTV,[1] and a transfer function (gamma curve) typical of CRTs. This specification allows sRGB to be directly displayed on typical monitors.

Unlike most other RGB color spaces, the sRGB gamma can not be expressed as a single numerical value. The overall gamma is approximately 2.2, consisting of a linear (gamma 1.0) section near black, and a non-linear section elsewhere involving a 2.4 exponent and a gamma (slope of log output versus log input) changing from 1.0 through about 2.3.
Expand
What is HDPC?
 
 
High-Bandwidth Digital Content Protection, developed by Intel, is a system for protecting content being transferred over DVI and HDMI from being copied. It’s built into the circuitry of the source and the receiver of video devices. Most consumer electronics products now require HDCP support when DVI or HDMI inputs or outputs are used.
Expand
I just received and unpacked my display monitor and I noticed that there are several bright patches around the edge of the screen when I look at a black screen. Is the monitor defective?
 
 

Almost all LCD panels will have some slight light leakage around the edge of the screen when viewed with a black screen—especially on larger screens or when viewed at an angle. Pressure and stress on the LCD panel edges due to packaging and shipping can also increase this effect temporarily.

Allow the display a few days after being unpackaged to reach its optimal performance while the stress on the LCD panel is released. Don’t place any heavy items on the top of the display. Don’t leave the color sensor resting against the screen for longer than necessary. And never apply pressure to the screen or use suction cups to hold the color sensor in place.

Expand
How do I set the scheduler to work?
 
 

The scheduler lets you set up to seven schedules for your display to automatically power on and off. To program a schedule:

1. Using the "Schedule" menu, choose "Schedule Setting" and choose a schedule number. When the box next to the number turns yellow, the schedule can be programmed.
2. Choose the input source, time to turn on and off, and how often the schedule should repeat. (Use the arrows to select each menu, and the + and – buttons to make each selection.)

Keep in mind that when schedules overlap, the schedule with the higher number takes priority. For example, Schedule #7 takes precedence over Schedule #1.

Expand
What is image persistence?
 
 
Image persistence happens when a residual “ghost” image of a previous image remains on the screen. Image persistence is not permanent on LCD and plasma monitors. To prevent it, we recommend that you avoid displaying constant images for a long period of time. To learn more, read the image persistence white paper (PDF).
Expand
How can I access the Advanced OSD (On Screen Display) menu on an LCD90 series display?
 
 

Follow these steps:

1. Power off the monitor by pressing the power button.
2. Hold down the "Input" button.
3. Turn on the monitor by pressing the power button while continuing to hold the "Input" button.
4. After 4 seconds release the "Input" button.
5. The Advanced OSD menu will be shown.

Expand
How do I get rid of image persistence?
 
 
To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an image was on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to erase the image. As with all personal display devices, we recommend displaying moving images and using a moving screen saver at regular intervals whenever the screen is idle, or turning off the monitor when not in use.
Expand
How do I connect a DVD player or satellite/cable box?
 
 
This depends on the type of inputs coming from your DVD player or satellite/cable box. We recommend HDMI, which provides both digital picture and digital audio. If you aren’t able to use HDMI, we recommend a component connection. Please check your DVD player or satellite/cable box for more information.
Expand
How does the NEC hood attach to the display?
 
 
The hoods are custom made for the MultiSync 90 and PA series displays and attache via a series of clips that fit into holes on the back of the display. A flap on the top of the hood allows a color measurement sensor to be lowered into place for calibrating the display without having to remove the hood.
Expand
Can the NEC hood be used when the display is oriented in portrait mode?
 
 
No. The hood was designed for landscape orientation.
Expand
I noticed that the top of the LCD panel on the LCD3090WQXi moves slightly if I push it. Is this normal?
 
 
Yes. In order to reduce pressure points around the edge of the LCD panel, which could cause screen uniformity problems, it’s suspended within the monitor frame. Some slight movement is normal, but be sure to never apply any pressure to the screen surface.
Expand
What are the differences between the LCD2690WUXi and LCD2690WUXi2?
 
 

The following are the main changes made to the LCD2690WUXi2:

1. The color gamut has been increased and the green primary now almost exactly match those of AdobeRGB. The red and blue primaries exceed that of AdobeRGB.
2. The contrast ratio has been improved from 800:1 to 1000:1.
3. The maximum typical luminance has decreased from 400 to 320 cd/m².
4. The white point of the sRGB Emulation mode can now be calibrated by SpectraView.
5. A shortcut feature has been added on the On Screen Display to make it easier to switch between different color modes such as Programmable (calibrated) and sRGB Emulation.

Expand
Is there any way to upgrade the firmware in my LCD2690WUXi to that of the newer LCD2690WUXi2?
