The Lenovo ThinkVision T24-40 is a 23.8-inch LCD monitor with IPS panel technology, designed for use in office environments, home offices, and professional workstations. The device features a screen diagonal of 60.5 cm and a native resolution of 1920 x 1080 pixels in Full HD format with an aspect ratio of 16:9. The screen technology is based on an LED-backlit IPS panel, ensuring uniform color reproduction and wide viewing angles. Brightness is typically 250 cd/m², providing sufficient light in normally lit rooms. Response time is 6 ms in Normal mode and can be reduced to 4 ms in Extreme mode, minimizing motion blur. The maximum refresh rate is 120 Hz, enabling smooth image reproduction for dynamic content. Viewing angles are 178° horizontally and vertically, ensuring clear visibility from various positions. The panel supports 8-bit color depth and a color palette of 16.7 million colors, achieving 99 % coverage of the sRGB and Rec. 709 color spaces. Contrast ratios are 1500:1 (typical) and 3000000:1 (dynamic), allowing for good differentiation between darks and brights. The display is glare-free and flicker-free, reducing eye strain during prolonged use. Low-Blue-Light technology reduces blue light emission, minimizing eye strain during extended use.

Applications

The monitor is suitable for office applications, software development, data processing, and general productivity tasks. The high refresh rate and IPS technology also make it suitable for users who value clear and smooth display performance. Support for Windows 10 and Windows 11 enables integration into existing IT infrastructures.

Features and Equipment in Detail

The ThinkVision T24-40 includes an integrated USB hub with version 3.2 Gen 1 (also known as USB 3.1 Gen 1). This comprises one USB Type-B upstream port, three USB Type-A downstream ports, and one USB Type-C port. The USB-C port supports Power Delivery up to 15 W, enabling external devices such as laptops or tablets to be powered via the cable. Connections include an HDMI 1.4 port, a DisplayPort 1.2, and a VGA port, ensuring broad compatibility with various devices. There are no integrated speakers, camera, or microphone.

Technology Explained Simply

IPS technology (In-Plane Switching) ensures that colors and brightness are displayed uniformly even at oblique viewing angles. The LED backlighting (W-LED) enables even illumination of the screen. The 120 Hz refresh rate ensures smooth motion, especially during screen actions such as scrolling or video content. The 4 ms response time in Extreme mode reduces delay during fast image changes. Flicker-free technology and Low-Blue-Light function contribute to reducing eye strain. Energy efficiency class C (SDR) and a power consumption of 12 W in standard operation indicate moderate energy use.

Compatibility and Accessories

The monitor is compatible with Windows 10 and Windows 11. The connections allow for linking with computers, notebooks, and other devices. Support for USB Power Delivery (up to 15 W) enables power supply to external devices via the USB-C port. Modular camera and soundbar support (optional) allows integration of additional components such as the ThinkVision VoIP Stack MC60 Monitor Webcam or the MS30 Monitor Soundbar.

Mounting and Installation

The monitor is compatible with a VESA mounting bracket (100 x 100 mm), allowing it to be mounted on wall brackets or monitor stands. Ergonomic adjustments include height adjustment up to 15.5 cm, pivot function (−90° to +90°), swivel (−45° to +45°), and tilt adjustment (−5° to +23°). A Kensington slot enables mechanical security of the device against theft.

Operational Advantages

The combination of IPS panel, high refresh rate, and flicker-free technology creates a comfortable and productive working environment. Integrated USB connections increase connectivity options and simplify the use of peripheral devices. Ergonomic adjustments allow individual adaptation to the workspace. Support for Lenovo Display Fleet Manager (LDFM) enables IT administrators to centrally manage monitor assets, firmware updates, and settings.

Energy Efficiency and Operation

The monitor consumes 12 W in standard operation and 0.5 W in standby mode. Power consumption in the off state is 0.3 W. The internal power supply supports an input voltage of 100 to 240 V and a frequency of 50/60 Hz, enabling worldwide use. Energy efficiency class C (SDR) applies to the standard dynamic range. The warranty is at least 2 years, with the manufacturer guaranteeing at least 7 years of product support and 8 years of software and firmware updates.

Design and Dimensions

The monitor has a product color Black (Raven Black) and a black stand. Dimensions are 539.8 mm (width) and 190 mm (depth) including stand. Without stand, the depth is 45.3 mm. Weight is 5.1 kg including stand. The design is flat and features a 4-sided ultra-slim bezel construction.
