How can a SCART RGB signal from a DVD player or digital receiver be displayed on a plasma screen?
Because NEC appliances are chiefly used for professional display purposes, they are not fitted with SCART connectors as standard. To make NEC monitors SCART-compatible, NEC offers an optional SCART BNC cable and SCART D-Sub adapter.
Why is the picture unstable when connecting an SAT receiver or DVD player via SCART RGBs?
Some receivers or DVD players transmit too high a video signal level or too high a direct current component via the SCART connector. As a result the internal sync stripper may not correctly separate from the FBAS signal the frequencies needed for synchronisation, and the picture may then be displayed in unstable or distorted fashion. In this event the setting SCART2 should be selected under the menu item Option1/BNC Signal or SET UP. When this is done the synchronous line (the yellow connector = FBAS signal), which had previously been connected to the HSync input, will now be connected to the Video1 input. Connecting a 75-ohm resistor along the HSync line will also help.
Can the display also be operated vertically?
All current VP/VM/XM models can also be operated vertically. To adopt portrait mode you will need special software such as Portrait, which is available at www.portrait.com .
How can the image be improved/adjusted?
This is very easy because NEC displays, unlike those of many other providers, recognise the input signal and automatically adjust to it. This guarantees that the picture adopts the right format and synchronisation and that no time-consuming adjustment is necessary. Brightness, contrast & colour, etc., are individual settings for which most individual users have very different requirements depending on the application, environment or signal source, and accordingly they can be adjusted separately.
Can the display be used as a mobile unit?
For mobile use in-house stands fitted with rollers are available from various NEC partner firms. For transportation, flight cases are available to protect displays. Note that the displays must be transported vertically.
At what temperatures can the display operate?
As a rule plasma displays can operate at ambient temperatures of between 0° and 40°. You will find the exact details in the product presentation literature. For outdoor use NEC has partners who manufacture an air-conditioned case.
What stands and mountings does NEC offer for the displays?
Suitable stands are available for all models, and NEC also offers wall mountings (including tilting ones), ceiling mountings, pedestals and a special video wall mounting. For further details please consult the information on each individual model. NEC partners also offer individual solutions to meet special requirements.
Are plasma displays fitted with fans, and if so how loud are they?
Some plasma display models have fans, but at 22dB they are barely audible. Unlike projectors then, plasma screens produce hardly any distracting noise. For some types of device and applications fan-assisted cooling is necessary to prevent damage to the electronics and increase the unit’s lifetime.
Can electromagnetic radiation disrupt the display?
Plasma displays are completely insensitive to electromagnetic radiation.
Is a special graphics card needed to connect a PC?
In general any graphics card can be connected even if they only support classical 4:3 resolution (for example VGA, SVGA, XGA, SXGA, UXGA). However, to achieve optimum image quality it is advisable to use a graphics card which supports the physical resolution of the display. These can be obtained from virtually any graphics card manufacturer. A driver update is often all that is needed, but if not the company Power-Strip ( http://www.entechtaiwan.com/index.shtm ) offers a tool with which the signal can be adjusted to the nearest pixel.
Which television standards do NEC plasma displays support?
All the usual standards are supported by NEC displays. As well as the PAL signal most commonly used in Germany, they will also reproduce NTSC and SECAM signals.
Is the display fitted with an audio amplifier?
All current displays feature audio amplifiers, enabling equipment such as the elegant optional monitor speakers to be operated.
Can the display also be controlled externally?
NEC plasma displays feature an RS-232 interface with which the display can be controlled externally.
What warranty does NEC offer?
The warranty period is two years, though for a small surcharge payable on purchase this can be extended to three years. Under the warranty NEC offers an on-site service with the option of exchange or repair within the EU and also in Switzerland. We have either authorised service partners or a repair service in many other countries.
What connections does an NEC plasma display have?
NEC plasma displays offer a wide variety of connection options. Data signals can be connected via the classical Mini-D-Sub 15pin, BNC or DVI, while video sources can be connected via FBAS (video), S-video or component signal. Devices which support a SCART RGB output can also be connected via a corresponding cable/adapter available as an option from your NEC dealer.
Do you get good image quality when viewing from an angle?
Yes, because the plasma display’s viewing angle is 160° from all directions.
Do plasma displays stretch or squash the image?
There is no distortion of the 16:9 format signal (which is used for movies, for instance). In the case of computer signals we recommend using graphics cards which support the 16:9 format. These are available from almost all graphics card providers, though in some cases you will need to update the graphics card driver. For PowerPoint you just have to set up a MASTER in 16:9 format (e.g., Width 32; Height 18).
How long is the display’s lifetime?
The lifetime of a display is defined as the period after which it only has half the brightness of a new display. Naturally you can continue to use the display after this point has been reached. Under normal operating conditions (displaying video) the lifetime of the latest generation of devices is around 60,000 hours.
How thick is the panel and how much gap do I need to leave for a wall installation?
The panels are ultra-flat, being less than 9 cm thick in the case of the 42” model, for instance. When installing them you must ensure that the heat produced by the display can dissipate, for which a minimum distance from the wall of 4.5 cm is needed. To ensure that the air circulation is adequate when installing against a wall or in a recess, there should also be a gap of at least 5 cm to either side of the panel.
What resolutions do the plasma displays offer?
Plasma displays generally feature 16:9 format which matches the natural viewing angle of the eye. The physical resolutions are usually Wide VGA (853X480 pixels) or Wide XGA (1365x768 pixels), and of course computer signals such as XGA (1024x768) can also be reproduced. NEC plasma displays offer excellent signal processing of resolutions up to UXGA (1600x1200).
What happens if my plasma display malfunctions?
NEC offers a Europe-wide on-site service. This service is available for two years under the warranty for NEC plasma displays.
Contact details are provided here in Support under the menu item Service Hotline .
What is burn-in and what methods of reducing it does NEC offer?
Like any screen based on phosphor and all other gas plasma screens, plasma displays may under certain circumstances be susceptible to phosphor burn-in, which is the result of the uneven use of the phosphor in the cell. To prevent this, prolonged display of the same image should be avoided.
To reduce burn-in, NEC offers a reduced brightness long-life mode, pixel shift (where the image rotates around several pixels), all-white mode (whereby the screen displays a white image and no additional signal source for a certain period), screen wiper (whereby a white bar moves across the image) and also inverse mode (where colours are displayed inversely). XGA models also offer a soft-focus setting which softens sharp transitions.
What useful features do NEC plasma displays offer?
When connecting end devices the Auto Picture Adjust feature is particularly useful because it recognises the incoming signal automatically and adjusts it to the display. For presentations and video conferences the zoom and multipicture functions of the multimedia displays are very popular. The narrow frames of our Public Displays and integrated split calculator facilitate the creation of video walls with 2x2, 3x3, 4x4 or 5x5 screens. There is also a programmable timer which is ideal for time-controlled switching on and off and signal input selection, all without the need for any expensive external equipment. If portrait display is required, our Commercial Series can also be operated vertically.
Can NEC plasma displays also be used as televisions?
Naturally NEC plasma displays are also suitable for watching television. To do so, TV tuners, satellite receivers, video recorders or computers plus TV card may be connected.
What devices can be connected to the plasma display?
For presentations, computers and notebooks may be connected via the D-Sub, BNC or digital input (DVI), while TV tuners, satellite receivers, video recorders, DVD or HD players and video conference systems are all suitable video sources. Various RCA, Hodisen (S video), D-Sub and BNC connectors are available for connection purposes, and a special cable or adapter is available for SCART connection. All connectors (including the video board) come as standard, meaning that up to seven devices can be connected to the display.
What are the installation options for a plasma display?
NEC offers a wide variety of installation options. These include pedestals, stands, angled stands (20° or 70°), wall mounting and ceiling mounting. For video walls NEC offers a special multi-screen frame.
How can I avoid burn-in (image retention)?
Recomendations for optimizing operations of NEC Public Displays
How do I change my monitor's refresh rate in Windows?
1. Access the System Settings menu
2. From there, select the CONTROL PANELS folder.
How do I change my monitor's refresh rate using a Mac?
1. Access the System Settings menu.
2. From there, select the Monitors folder.
Where do I get a Windows .inf file, and how do I install it?
Monitors don't use drivers but, rather, there is a monitor information file used by the operating system to implement the Plug & Play feature of Windows.
You can download the Windows setup file from Display Drivers - LCD Downloads
How do I adjust my monitor's image?
This depends on the model. All of our monitors come with a user manual that will step you through the changing of the screen's size and position.
If your manual is not available, you can find it in our Product Support .
Why do I only get 16 colors as my choice for colors OR why is my only resolution option 640x480?
This issue has to do with the video card in the computer, not with the monitor. The monitor will do umlimited colors but it's the video card and it's driver that give you those choices.
We would recommend installing the latest drivers for your video card.
What do I do if my monitor's power light is orange, but I don't see anything on my monitor?
This typically indicates that the monitor is not receiving a video signal from the video card in the computer. You should verify that the card is the problem by trying the monitor on a different, working system. If you still do not get an image, please contact our support, the monitor might be defect.
The image on my display is flickering. How do I correct this?
Please refer to the monitor’s manual for the recommended refresh rate with your set resolution and adjust it accordingly.
What can I use to clean my screen?
Clean the LCD monitor surface with a lint-free, non-abrasive cloth. Case of persistent dirt, wipe with cloth permeated by water, ethanol, isopropyl-alcohol completely. Avoid using any cleaning solution or glass cleaner (ex Acid, Alkali and Acetone).
A special coating is provided on the glass (CRT) surface of this monitor to reduce a reflection and static electricity on the glass surface. Due to the delicate coating on the glass surface, use a lint-free, nonabrasive cloth (cotton or equivalent) and a non-alcohol, neutral, nonabrasive cleaning solution to minimize dust. If the screen requires more than a light cleaning, apply water or soften neutral detergent with much water directly to a soft cloth and use it upon wringing water, to clean the glass surface.
Why do images and fonts on my LCD look choppy and/or blurry?
Unlike CRT displays, the LCD panel has a fixed pixel format over a set area. In order for LCD's to expand resolutions to full screen an interpolation must be performed. When the interpolated resolution is not an exact multiple of the native resolution some lines appear thicker than others. Please refer to the display manual for the optimum resolution.
If your manual is not available, you can find it in our Product Support.
How do I use the On Screen Menu?
NEC Display Solutions sells a wide variety of monitors. We use different versions of OSM’s (On Screen Manager) depending on the features of the monitor. Please refer to the manual for detailed instructions for the OSM usage.
How do I remove the “Resolution Notifier” message?
To permanently turn of the “Resolution Notifier” message Bring up the OSM. Go to the “TOOLS” tag depending on the monitor there may be one or two tools tags If there are two go to the second tag. Under the “TOOLS” tag select the symbol. This is the “Resolution Notifier” setting. Use the < > buttons to set the Notifier to OFF.
What are dead pixels in LCD displays?
The manufacturing process for LCD displays requires millions of transistors in each panel. Limitations of the manufacturing process sometimes result in dead pixels. A "dead pixel" can take the form of either a contrast spot or a black spot. A contrast spot appears when a completely gray screen is displayed. A black spot appears when a completely red, green or blue screen is displayed.
Why will my monitor not power on? (Vacation switch)
If your monitor will not power on, the first thing to check is the “vacation switch”. The vacation switch will be located on one of the sides of the monitor or on the bottom for our larger monitors (above 30 inch). Make sure this switch is in the ON “ I” position. Many NEC Display Solutions monitors are made with vacation switches. The vacation switch enables the monitor to be turned off completely.
When powering on the computer, I get an “Out of Range” error message. The computer goes into safe mode and I cannot get anything to work right. It will not enter back into normal mode. What can I do?
The monitor will display an OUT of RANGE message when the output of the video card in the computer exceeds the monitor's capability. The easiest solution is to get to a point where you can reload the drivers for the monitor.
Reset your monitor to its default settings.
1. Restart Windows in “Safe Mode”
2. Click Start, then select Settings, then Control Panel.
The Control Panel window opens.
After the default driver is working reload the drivers for you monitor
Aperture grille wires...what are they? (Two faint horizontal lines in the image.)
This is not a defect, the lines are built into the CRT. The MultiSync FP and FE series monitors use an aperture grille CRT. This type of CRT has thin vertical color stripes that run from the top of the screen to the bottom. The color stripes are separated by a thin wires that make up the grill. The horizontal lines you see are shadows of two horizontal damping wires used in this type of CRT to maintain image stability.
