Where do I get a Windows .inf file, and how do I install it?
 
 
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.
Expand
What are 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.

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.)

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 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
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.

Where can I find documentation on RS232 codes?
 
 
RS232 external code commands can be found under the Products section, under the Downloads link.

What inputs can be used for TileMatrix?

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.

How can I find the IR code to program my universal remote control?
 
 
NEC Display does not provide IR code to our large screen public displays.
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.

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 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.

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.
