Here are some terms to know when choosing the right monitor for your business.
The aspect ratio of an image is the ratio of the width of the image to its height. Sample “square” aspect ratios (shown below) can be described as 4:3 and 5:4, while sample “widescreen” aspect ratios are 16:9 and 16:10
Auto Adjust / Auto Sync
A special one-touch Auto Adjust button allows users to quickly set the display panel to match their preferences and provides users with excellent front-of-screen performance and minimal set up.
The visual and subjective quality of how bright an object appears, how much visible light is coming off the object being perceived by the eye (this is a subjective perception).
Refers to how well the three (red, green, and blue) color guns intersect at each pixel. The better the guns converge, the more closely the red, green, and blue colors fall directly on top of each other, creating a sharper image. An analogy for poor convergence would be the printed colors of a comic strip page, which, when not converged, show a color "shadow" outside the lines of the drawing.
Defines the whiteness of the white on the screen. Variations are measured in degrees Kelvin. Natural colors used in life-like images, such as people or landscapes, look more true to life when displayed at a color temperature of 6500K. Black text on a white page is better represented by a color temperature of 9300K.
The measure of a display system, defined as the ratio of the luminance of the brightest color (white) to that of the darkest color (black) that the system is capable of producing. The higher the contrast ratio, the more brilliant the display.
Contrast ratio - Dynamic
Utilizes the LED backlight to independently control light output to different areas of the screen in order to enhance contrast ratio even further.
Contrast ratio - Static
The ratio of the luminance of the brightest and the darkest colors the system is capable of producing simultaneously at any instant of time.
Concealed Cable Management
Select HP monitors feature a vertical insertion of power and signal cables into a recessed section behind the monitor, which is also neatly enclosed behind a panel. This allows the monitor to be pushed more closely up against a wall, as well as providing a tidy look to the back of the monitor. This delivers a professional appearance when the back of the monitor is in view.
DisplayPort is a digital display interface standard put forth by the Video Electronics Standards Association (VESA) since 2006. It defines a new royalty-free, digital audio/video interconnect, intended to be used primarily between a computer and its display monitor, or a computer and a home-theater system.
DisplayPort is a competitor to the HDMI connector (with HDCP copy-protection), the de facto standard digital connection for high-definition consumer electronics devices.
Digital Visual Interface (DVI) is a video interface standard designed to provide very high visual quality on digital display devices such as flat panel LCD computer displays and digital projectors. It was developed by an industry consortium, the Digital Display Working Group (DDWG) to replace the "legacy analog technology" VGA connector standard. It is designed for carrying uncompressed digital video data to a display. It is partially compatible with the High-Definition Multimedia Interface (HDMI) standard in digital mode (DVI-D), and VGA in analog mode (DVI-A).
DVI comes in two main types:
Stands for “DVI-Integrated” and supports both digital and analog signals; therefore, a user may connect a PC with a VGA port to a display with DVI-I using a special VGA > DVI-I cable.
Stands for “DVI-Digital” which supports digital signals only.
A program established by the Environmental Protection Agency (EPA) to become an international standard for energy efficient consumer products. It was formally launched on June 17, 1993. Devices carrying the Energy Star logo, such as computer products and peripherals, kitchen appliances, buildings and other products, generally use 20%–30% less energy than required by federal standards.
EPEAT is a system that helps purchasers evaluate, compare and select electronic products based on their environmental attributes. The system currently covers desktop and laptop computers, thin clients, workstations and computer monitors.
Desktops, laptops and monitors that meet 23 required environmental performance criteria may be registered in EPEAT by their manufacturers in 40 countries worldwide. Registered products are rated Gold, Silver or Bronze depending on the percentage of 28 optional criteria they meet above the baseline criteria. EPEAT operates an ongoing verification program to assure the credibility of the registry.
EPEAT® ratings mean your investment is has met required environmental performance criteria enabling a responsible purchase.
High-bandwidth Digital Content Protection (HDCP) is a form of digital copy protection to prevent copying of digital audio and video content as it travels across DisplayPort, Digital Visual Interface (DVI), High-Definition Multimedia Interface (HDMI).
HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transmitting uncompressed digital data. HDMI supports, on a single cable, any uncompressed TV or PC video format, including standard, enhanced, and high-definition video; up to 8 channels of compressed or uncompressed digital audio; and a Consumer Electronics Control (CEC) connection. Because HDMI is electrically compatible with the signals used by Digital Visual Interface (DVI), no signal conversion is necessary, nor is there a loss of video quality when a DVI-to-HDMI adapter is used.
The ability for the monitor head to move low and high. Monitors with height adjustment* provide a full range of height possibilities resulting in maximum comfort.
The height of the monitor should allow your head to be balanced comfortably over your shoulders. It should not cause your neck to bend forward uncomfortably or backward to any degree. If your neck is aching or your eyes feel strained, you might want to consider adjusting the height of your display.
Low monitor placement is perfect for children in educational settings or for those who are shorter in stature.
High monitor placement is perfect for those who are taller in stature as it makes the screen easier to view without causing neck strain.
Liquid Crystal Display (LCD)
An LCD contains two grooved plates which are sandwiched together with liquid crystals along the top plate lining up in one direction, and those along the bottom line up in another direction. The entire panel is then "backlit" so that when light travels through the panel, it shows through the spaces between the crystals.
Pivot enables the monitor head to be rotated 90 degrees into a vertical position (also called portrait mode). This eliminates the need to continually scroll up and down on vertically oriented programs. It is ideal for viewing email, PDFs, documents and spreadsheets.
A contraction of the words "picture element," these are the basic dots on the display screen that make up the image you see.
Measures the speed that the entire screen is rescanned. Higher frequencies reduce flicker, because they light the pixels more frequently, reducing the dimming that causes flicker; also called vertical frequency.
The number of distinct pixels in each dimension that can be displayed. In common usage, this refers to the number of pixels displayed on screen horizontally and vertically. A resolution of 1680 x 1050 means you can see 1680 pixels horizontally and 1050 vertically. Higher resolution means that you can see more of your image on the screen without scrolling or panning.
The amount of time a pixel in an LCD monitor takes to go from black to white and back to black again. It is measured in milliseconds (ms). Typically, lower numbers mean faster transitions and therefore fewer visible image artifacts.
The ability for the monitor head to be rotated left or right. This enables users to share screen images without causing visual distortion.
TCO Displays Certification
A series of product certifications for monitors set by TCO Development, owned by the Swedish Confederation of Professional Employees. The certifications are named after years and confirm that your investment has been designed for both the user and the environment. Labeled products must meet strict environmental demands and requirements cover a wide range of issues such as: environment, ergonomics, usability, emission of electrical and magnetic fields, energy consumption and electrical and fire safety.
The environmental demands concern, among other things, restrictions on the presence and use of heavy metals, brominated and chlorinated flame retardants, CFCs (freons), and chlorinated solvents. The product must be prepared for recycling and the manufacturer is obliged to have an environmental plan, which must be adhered to in each country where the company implements its operational policy.
The energy requirements include a demand that the computer and/or display shall reduce its power consumption to a lower level after a certain period of inactivity, in one or more stages. The length of time to reactivate the computer shall be reasonable for the user.
Thin Film Transistor (TFT)
Each pixel on the TFT screen is either "on" or "off" because the transistor for that pixel is on or off. This creates a crisp, steady display without the flicker seen in CRTs.
The ability for the monitor head to move up and down. Tilt adjustment enables a user to change the viewing position of the display, creating a more comfortable view of the screen. Users whom view a monitor through the lower portion of bifocal, trifocal or progressive addition lenses may find tilt settings extremely helpful.
Universal Serial Bus (USB) offers a single connector
The horizontal or vertical angle at which the user can view the screen image with no loss of color fidelity or image clarity.
A VGA connector is a three-row 15-pin DE-15 connector. The 15-pin VGA connector is found on many video cards, computer monitors, and some high definition television sets. VGA connectors and cables carry analog component RGBHV (red, green, blue, horizontal sync, vertical sync) video signals, and data.
Video Electronic Standards Association. A group made up from the video electronics industry to review proposals and develop standards to promote uniformity and economies of scale in the video electronics industry.
The horizontal or vertical angle at which the user can view the screen image with no loss of color fidelity or image clarity. Wide viewing angles makes it easier to share your screen with other without color or clarity loss.
White Light Emitting Diode (WLED) is a backlight technology which provides the ‘light source’ for the display. ‘LED’ backlighting technology is quickly replacing ‘CCFL’ (Cold Cathode Florescent Lamp) backlight technology as the backlighting source for LCD monitors. WLED panels consume less power than CCFLs and because they are solid state components, they are more resistant to damage caused by external shock. Most importantly, WLEDs eliminate the use of mercury, which addresses the growing concern of these substances and furthers ecological conservation efforts.
