Features

Built-in Speaker Function

This monitor lacks built-in speakers, requiring users to use external audio solutions like headphones or dedicated speakers. While this might be a drawback for some, it can be mitigated by using high-quality external audio devices for a superior sound experience. The absence of integrated speakers also contributes to a slimmer and lighter design, enhancing portability.

Blue Light Reduction Function

The blue light reduction function helps to minimize eye strain and fatigue during prolonged use. This feature is particularly beneficial for users who spend many hours in front of the screen, reducing potential discomfort and promoting better eye health. By filtering out harmful blue light emissions, the monitor provides a more comfortable viewing experience, especially during nighttime use.

Height Adjustment Function

The absence of height adjustment may limit the ergonomic flexibility of the monitor. Users might need to use external stands or props to achieve an optimal viewing angle, which can be less convenient. However, the adjustable kickstand offers some degree of tilt adjustment, allowing users to customize the screen position to their preference.

Tilt Adjustment Function

The tilt adjustment function allows users to adjust the viewing angle, reducing glare and improving visibility. This feature is useful for different viewing positions and lighting conditions, ensuring a more comfortable and optimized visual experience. The ability to tilt the screen can also help to reduce neck strain and improve overall ergonomics.

Pivot Function

The absence of a pivot function means the screen cannot be rotated to a vertical orientation. This might limit its usability for tasks like reading long documents or coding, where a vertical screen orientation can be beneficial. Users who require this functionality may need to consider alternative monitors with pivot capabilities.

VESA Mount Compatibility Function

The lack of VESA mount compatibility limits the mounting options for this monitor. Users cannot mount it on a wall or monitor arm, restricting it to desk or stand use. This can be a drawback for users who prefer a cleaner workspace or need more flexible positioning options. However, the built-in kickstand provides a stable and adjustable support for desktop use.
