The monitor also features an "Eco Mode" with predefined settings (Standard, Text, Internet, Game, Movie, Sports, Reading, Uniformity) to optimize display for different content types and reduce eye strain.
- Dynamic Contrast Ratio (DCR): This feature can be enabled or disabled to dynamically adjust the contrast, enhancing the visual depth of images.
- High Dynamic Range (HDR) Mode: The monitor supports HDR modes (Picture, Movie, Game) for improved contrast and color accuracy, though certain other settings (Contrast, Eco Mode, Gamma) become unavailable when HDR is active.
- Color Setup: Comprehensive color adjustments are available, including color temperature presets (Warm, Normal, Cool, sRGB) and a User mode for manual RGB gain control.
- DCB Mode (Dynamic Color Boost): This feature offers various modes (Full Enhance, Nature Skin, Green Field, Sky-blue, Auto Detect, or OFF) to dynamically enhance specific color ranges, improving the vibrancy and realism of images. A "DCB Demo" mode is available to showcase the effect.
- LowBlue Mode: Designed to reduce blue light emissions, this mode has presets (Multimedia, Internet, Office, Reading, or Off) to decrease the blue light wave by controlling color temperature, helping to alleviate eye fatigue during prolonged use.
- Picture Boost: This unique feature allows users to define a specific "Bright Frame" area on the screen and adjust its brightness, contrast, and position independently. This can be useful for highlighting particular content or for specific viewing scenarios.
- OSD Setup: The OSD menu itself is customizable, allowing users to select the display language, set the timeout duration, adjust its horizontal and vertical position, and control its transparency. A "Break Reminder" can be activated to prompt users to take breaks after continuous work.
- PIP/PBP Settings: Users can enable Picture-in-Picture or Picture-by-Picture modes, select main and sub-screen sources, adjust the sub-screen size (Small, Middle, Large), and position it (Right-up, Right-down, Left-up, Left-down).
