The Lenovo ThinkVision L2440x Wide enables you to be environmentally conscious without compromising performance. Pioneering new energy conservation and recycling technologies, the new L2440x Wide monitor is Lenovo’s first low halogen product that is also mercury-free and arsenic-free and uses up to 60% less power than conventional models. The Electronic Product Environmental Assessment Tool (EPEAT) rates the ThinkVision L2440x Wide in the Gold category, making it the most environmentally friendly monitor available today .

The L2440x Wide is the ideal choice for mobile users looking for an excellent screen display for increased productivity when working at the office. It offers users up to 225% additional work area over the ultra-portable notebook with easy access using DisplayPort and USB connectors. The incorporated ThinkVantage® design enhances usability and makes the monitor easy to use. It complements the design of the ThinkPad® and ThinkCentre® systems and includes attachments for the ThinkVision Soundbar (sold separately .

VESA high refresh video signal timings
The Lenovo ThinkVision L2440x Wide LCD monitor supports a wide range of display modes, including a selection of the VESA timings of incoming video signals at up to 75 Hz (non-interlaced) for the following screen resolutions:
• 640 x 480
• 800 x 600
• 1024 x 768
• 1280 x 1024
• 1440 x 900
• 1600 x 1200
• 1680 x 1050
Appropriate video-adapter hardware and software must be installed in the attaching system unit. Monitors are compatible with popular PC system units. VESA Display Data Channel (DDC). The Lenovo ThinkVision L2440x Wide LCD monitor supports the DDC protocol to level Command Interface (CI). Basic configuration information can be passed to a system unit from its attached monitor. Often referred to as Plug and Play, the protocol enables a DDC-enabled system unit to automatically configure the video adapter to drive the attached monitor at its optimum display mode without end user intervention. For best use, the attaching system unit must also be hardware- and software-enabled for DDC operation. The capabilities of the monitor are held in nonvolatile monitor memory in an encoded format. The data is received from the monitor by the system unit during boot-up and system configuration. The Extended display identification data (EDID) sent by the monitor to the attached system unit also includes the monitor’s serial number and other identification information. This can be held in the system unit until requested; for example, by a department local area network (LAN) administrator needing to assess the location of all equipment connected to the LAN. Date information transmitted in the monitor EDID data conforms to VESA EDID standard V2. This requires the year of manufacture (YOM) to be stored in a one-byte field as an offset from 1990, as derived from the following equation: An international industrial standard by the name of DDC/CI was developed by VESA to expand upon an existing DDC standard. This new standard adds control functionality without the need for additional connections.

The main advantage of DDC/CI is its bi-directional communication structure between PC and monitor, which does not require a separate cable. All data are transmitted in both directions via the video graphics card and the standard VGA or DVI signal cable. This capability allows for functions like monitor control, adjustments, and diagnostics to be conducted via software using the mouse and keyboard. In an enterprise or firm, this capability also allows the potential of remote diagnostics and asset management by a technician via the LAN. Customer-supplied software is needed to implement these functions.

International Organization for Standardization (ISO)/DIS 13406 Part 2
ISO/DIS 13406 Part 2 ensures ergonomic requirements are met when the ThinkVision L2440x Wide LCD monitor forms part of an ISO-compliant system. ISO/DIS 13406 Part 2 is an international standard addressing ergonomic factors for flat-panel displays. ISO-capable elements do not necessarily make an ISO-compliant system when put together. To satisfy the requirements of ISO 13406 Part 2, a complete platform must be tested and must comply with all applicable elements of ISO 13406 Part 2. The platform includes:
• System unit
• Operating system
• Fonts
• Video subsystem
• Monitor
• Keyboard
• Mouse
When all contributing platform components satisfy their portion of the requirements, as verified by the required total system testing, the platform is ISO 13406 Part 2-compliant. Low frequency electromagnetic emissions The Lenovo ThinkVision L2440x Wide LCD monitor meets the Swedish Board for Technical Accreditation (SWEDAC) MPR-2 requirements and those of MPR-3. MPR-2 is a guideline developed by the SWEDAC to limit the electromagnetic emissions and electrostatic fields generated by workstations. MPR-3 is the colloquial name for the Swedish Standard SS 43614 90:1995. Electric and magnetic fields with frequencies between 5Hz and 2kHz are called extremely low frequency (ELF) fields. Those with frequencies between 2 kHz and 400 kHz are called very low frequency (VLF) fields.
