This Lenovo L27i-4A, 27" monitor with FHD 1920x1080 resolution is suitable for comfortable work with documents, web content, and multimedia. It provides natural image reproduction, comfortable viewing, and stable performance, satisfying user needs for a universal work screen.
IPS technology ensures more accurate color representation and stable image when viewed from the side. Compared to TN and VA, it changes brightness and contrast less with viewing angle, making the displayed data visually more reliable and technically more accurate.
AMD FreeSync provides adaptive monitor refresh rate with variable frequency range. It helps to prevent image tearing that occurs due to unsynchronized frame output. The technology improves motion uniformity and stability, especially in situations with variable frame frequency.
The refresh rate of 100 Hz enhances the perception of dynamic scenes, thanks to more frequent frame updating. It reduces motion blur and improves image stability during swift content changes, which is particularly useful in interactive and highly dynamic scenarios.
The Flicker-Free technology reduces or completely eliminates flickering in lighting, ensuring a stable and uniform image. The reduced visual vibration lessens eye strain and improves comfort during prolonged use, especially when using the monitor at a lower brightness level.
Tilt mechanism allows to change the screen's vertical angle without moving the whole construction. Such adjustment improves workplace ergonomics, ensures stable image quality and helps to adapt the monitor to the user's individual preferences or specific tasks.
VESA wall mount allows you to install a monitor on the wall, adhering to a uniform industrial standard. It facilitates the choice of mount, increases the flexibility of workspace organization, and allows you to adjust the height and angle of placement, regardless of the desk or tripod.
Built-in speakers allow the monitor to independently process and play audio signals, reducing the need for additional devices. This makes the workplace more compact and facilitates connection. The speakers provide basic sound support for multimedia and communication applications.
The D-Sub interface supports analog video signals, allowing the monitor to be connected to older generation equipment without additional adapters. It provides stable image transmission and correct graphics replay, making the monitor a universal solution for various operating systems and simplifying integration in existing configurations.
HDMI is a digital interface designed for stable video and audio transmission with a single cable. This approach reduces the number of connections and prevents unnecessary signal conversion. HDMI ensures a reliable connection, high throughput, and precise operation with modern devices without loss of quality.
Warranty
Lenovo provides this model with a 3 year warranty at all certified service centres.
DVI is a digital standard and ensures high image quality, however, thanks to the big size of the plug and the inability of the standard to develop further due to a few technical restrictions this type of connection is gradually losing its popularity to modern HDMI and DisplayPort standards.
