Due to the delicate coating on the glass surface, use a lint-free, non-abrasive cloth and a non-alcohol, non-abrasive cleaning solution to minimize dust. If the screen requires more than a light cleaning, clean the surface with a soft cloth dampened with water or a diluted, gentle detergent.
CAUTION: Never use benzene, thinners, acid/alkaline detergent, alcohol detergent, detergent with abrasive powder, detergent with antistatic agent, or other strong cleansers.

1. In Windows, right-click on the desktop.
2. Click on "Properties."
3. Click on the "Settings" tab. You can adjust your screen resolution with the slider bar or continue below for more advanced changes.
4. Click on the "Advanced" button.
5. Click on the "Adapter" tab. Choose your preferred refresh rate in the drop-down menu.
6. Click on "List All Modes" and choose your refresh rate.

INF files are commonly known as drivers. Your operating system uses them to identify the monitor's name and resolution.

We recommend using the NEC Monitor Installer for quick and easy installation of all your drivers.
A driver is software that controls a computer component or device, such as a display monitor. Drivers are specific to each device, and we recommend that you install the proper drivers using the NEC Monitor Installer.

Windows 2000, XP, Vista and later operating systems don't require drivers.
You can download drivers from the Support & Service section of our site by searching for your specific model.

Your computer's video card and its driver are limiting your options. We recommend installing the latest drivers for your video card.

Your monitor settings are probably incorrect. To adjust them:

1. In Windows, right-click on the desktop.
2. Click on "Properties."
3. Click on the "Settings" tab.
4. Click on the "Advanced" button.
5. Click on the "Adapter" tab. Choose your new refresh rate from the drop-down menu.
6. Click on "List All Modes" and choose your refresh rate.

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.)
Zip files are an easy way to archive, compress, transfer and copy files. To open a zip file, Windows users commonly use WinZip while Mac users typically use StuffIt Expander.
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.
Because each monitor is different, we recommend that you refer to the user manual for your model.

1. Open the On Screen Menu.
2. Go to the “Tools” tag. (If there are two tags, choose the second.)
3. Select the symbol under the “Tools" tag. (This is the Resolution Notifier setting.)
4. Use the left- and right-arrow buttons to turn the notifier off.

Windows 2000 & Later:

1. Right-click on your desktop.
2. Choose Properties from the pop-up menu, then choose the Settings tab.
3. Use slider bar to change the resolution.

Mac OS X:

1. From the Apple menu select System Preferences, then select Displays.
2. Within the "Display" tab, click on the "Detect Display" button. This will do a scan of the monitor information and list the resolutions supported by this monitor.
3. Choose your desired resolution.

Because each monitor is different, we recommend that you refer to the user manual for your model.
The NEC Professional 90 Series models with the letter "i" in the model use IPS panels.
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.)
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.
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.
RS232 external code commands can be found under the Products section, under the Downloads link.
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.
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.
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).
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.
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.
