The Lenovo ThinkVision P24QD-40 is a 23.8-inch LCD monitor with Quad HD resolution (2560 x 1440 pixels) and IPS panel technology, specifically designed for professional work environments in offices or home offices. The display offers a visible screen size of 60.5 cm diagonal and is designed for precise colour reproduction and uniform image quality across the entire screen. The screen technology is based on W-LED backlighting, achieving a brightness of 300 cd/m², which is sufficiently bright for use in well-lit rooms. The contrast ratio is 1500:1 (typical) and 3000000:1 (dynamic), ensuring good visibility of depth and detail in the image. Colour coverage is 99 % of the sRGB and Rec. 709 colour spaces, ensuring accurate colour representation for office applications and design work. The colour depth is 8 bit, and the refresh rate can reach up to 120 Hz, enabling smooth motion during multitasking and presentation-related applications. The response time is 6 ms (Gray to Gray) in normal mode and 4 ms in fast mode, ensuring minimal image blurring. The viewing angles are 178° horizontally and vertically, ensuring wide visibility even from the side. The display features an anti-reflective surface that reduces glare and improves readability in daylight.

Applications

The monitor is designed for professional workstations, particularly for office users who value clear, accurate colour representation and ergonomic operation. It is suitable for word processing, spreadsheet applications, presentations, and for applications requiring high image quality and multitasking capability. Support for HDR10 (High Dynamic Range) enables extended dynamic range in compatible applications, with energy efficiency class D for SDR (Standard Dynamic Range) and F for HDR. The power consumption in standard operation is 16.5 W, in standby 0.5 W, with a maximum power consumption of 210 W.

Functions and Equipment in Detail

The monitor features an integrated USB hub connected via a USB Type-C and a USB Type-B upstream port. This enables power supply and data transfer for external devices. There are four USB-A ports (USB 5 Gbps) and one USB-C port (USB 5 Gbps, 15 W PD) downstream, with the USB-C port also supporting DisplayPort Alternate Mode (Alt Mode). The USB-C power supply can deliver up to 140 W, sufficient to power laptops and other devices. Additionally, there is an HDMI port (version 2.1) and two DisplayPort ports (version 1.4), one of which functions as an output. The network connection is via an RJ45 Ethernet port (10M/100M/1000M/2500M). An integrated KVM switch enables control of multiple devices via a single keyboard and mouse connection.

Technology Explained Simply

IPS technology ensures uniform colour and brightness distribution across the entire screen, even when viewed from the side. The W-LED backlighting ensures even illumination without visible hotspots. Support for HDR10 extends the colour and brightness range, making images and videos appear more vivid, provided the source delivers HDR content. The Low-Blue-Light technology reduces blue light emission, which can help reduce eye strain. The integrated KVM function allows a single keyboard and mouse connection to be used for multiple connected computers, enabling a more efficient workstation setup.

Compatibility and Accessories

The monitor is compatible with Windows 10 and Windows 11. The connections support modern standards such as HDMI 2.1, DisplayPort 1.4, and USB-C with DisplayPort Alternate Mode. Power delivery via USB-C up to 140 W makes it suitable for use with compatible laptops. The integrated KVM function can be extended with Lenovo ThinkColour software, which supports display settings and device management. Support for Lenovo Display Fleet Manager (LDFM) enables central management of multiple monitors in a network.

Mounting and Installation

The monitor features an ergonomic stand with height adjustment up to 15.5 cm, swivel range from -45° to +45°, tilt adjustment from -5° to +23.5°, and pivot function from -90° to +90°. The VESA mounting (100 x 100 mm) allows installation on wall mounts or monitor arms. An integrated cable lock slot (Kensington) protects the device against theft. The Plug & Play function simplifies installation, as no additional configuration is required.

Operational Advantages

The monitor offers high image quality with precise colour reproduction, which is beneficial for professional applications. The ergonomic adjustments allow individual adaptation to the workspace, increasing work comfort. The integrated USB hub function and support for USB-C with Power Delivery (up to 140 W) reduce the number of required cables and simplify workstation setup. The KVM function enables efficient use of multiple computers with a single input device. Support for HDR10 and Low-Blue-Light technology contribute to visual quality and eye protection. The energy efficiency class D (SDR) and F (HDR) comply with current standards for office equipment.

Design

The monitor has a slim, flat design with a black front and base in the colour Eclipse Black. The side bezel width is 2 mm, resulting in a modern, minimalist design. The removable stand allows flexible mounting. The surface is anti-reflective to minimise glare.

Certifications

The monitor is ENERGY STAR® certified, complies with TCO 10.0 and TCO Edge 2.1 standards, is EPEAT™ Gold certified, and meets the requirements of the EU energy efficiency class (Level-D). It is also certified with TÜV Rheinland® Eye Comfort 5 Stars and Eyesafe® Display 2.0, confirming eye comfort. The Low-Blue-Light technology is hardware-based and reduces blue light emission.

Software Support

The Lenovo ThinkColour software supports Windows 10 and 11 and enables control of display settings. The Lenovo Display Fleet Manager (LDFM) enables central management of multiple monitors. The integrated KVM function supports control of multiple devices via a single keyboard and mouse connection.

Energy Consumption

The power consumption in standard operation is 16.5 W, in standby 0.5 W. The maximum power consumption is 210 W. The energy consumption per 1,000 hours is 14 kWh (SDR) and 22 kWh (HDR). The energy efficiency class is D (SDR) and F (HDR).
