With even further improved energy efficiency, and an even thinner bottom bezel, the EV2451 combines space saving with energy saving. The monitor features ultra-slim bezels on the sides. Electrostatic switches are placed on the front of the monitor for easy adjustment of monitor settings. Furthermore the bezels are flush with the screen surface, making a completely flat screen perfect for multi-monitor configurations. Due to the way brightness is controlled on LED backlights, a small number of people perceive flicker on their screen which causes eye fatigue. The FlexScan EV series utilizes a hybrid solution to regulate brightness and make flicker unperceivable without any drawbacks like compromising color stability - even on low brightness settings. To prevent eye fatigue, a brightness sensor called Auto EcoView detects the changes in the ambient brightness that occurs throughout the day and automatically adjusts the screen to the ideal brightness level.
