Size of the display for this product, measured diagonally, usually in inches.

Display diagonal

The number of distinct pixels in each dimension that can be displayed. It is usually quoted as width × height, with the units in pixels: for example, "1024 × 768" means the width is 1024 pixels and the height is 768 pixels. The higher the number of pixels, the sharper the image.

HD type

The aspect ratio is the ratio of the width of an image to its height. The native aspect ratio is the one which the projector/display is particularly designed for. Images shown in native aspect ratio will utilize the entire resolution of the display and achieve maximum brightness. Images shown in other than native aspect ratio will always have less resolution and less brightness than images shown in native aspect ratio.

Native aspect ratio

Panel type

A backlight is a form of illumination used in liquid crystal displays (LCDs). One type of backlight is made by LEDs, which can be either white or RGB (red green blue). White LEDs are used most often in notebooks and desktop screens, and in virtually all mobile LCD screens. RGB LEDs for backlighting are found in high-end color proofing displays such as HP DreamColor LP2480zx monitor or selected HP EliteBook notebooks, as well as newer consumer grade displays such as Dell's Studio series laptops which have an optional RGB LED display.

Technical details

TCO Certified is the world’s most comprehensive sustainability certification for IT products, helping you make responsible product choices that drive the industry in a sustainable direction. Using TCO Certified also supports your organization’s efforts to reduce risk and take the next step in social and environmental responsibility.

The Electronic Product Environmental Assessment Tool (EPEAT) is a global ecolabel for the IT sector. The EPEAT program provides independent verification of manufacturers’ claims and the EPEAT online Registry lists sustainable products from a broader range of manufacturers than any comparable ecolabel. National governments, including the United States, and thousands of private and public institutional purchasers around the world use EPEAT as part of their sustainable procurement decisions. EPEAT helps purchasers, manufacturers, resellers, and others buy and sell environmentally preferable electronic products. EPEAT-registered products must meet environmental performance criteria that address: materials selection, supply chain greenhouse gas emissions reduction, design for circularity and product longevity, energy conservation, end-of-life management and corporate performance. Bronze-rated products meet all of the required criteria in their category. Silver-rated products meet all of the required criteria and at least 50% of the optional criteria, while Gold-rated products meet all of the required criteria and at least 75% of the optional criteria.

G means that the product is rated in its category in terms of energy efficiency. The Energy Labeling system is based on EU Regulation 2017/1369/EU.
