Features

Built-in Speaker Function

The inclusion of built-in speakers provides convenient audio output, eliminating the need for external speakers and reducing cable clutter. This is particularly useful for on-the-go use and quick setups where carrying extra speakers is not feasible. The audio quality is adequate for general use.

Blue Light Reduction Function

The absence of a blue light reduction function may lead to eye strain and fatigue during prolonged use. Users who spend many hours in front of the monitor may need to use software-based blue light filters or wear blue light blocking glasses to mitigate these effects.

Height Adjustment Function

The lack of a height adjustment function may require users to use external stands or accessories to achieve an optimal viewing angle. This can be a drawback for users who prioritize ergonomics and comfort during extended use, as it limits the flexibility of positioning the screen.

Tilt Adjustment Function

The tilt adjustment function allows for optimizing the viewing angle and reducing glare, improving visibility and comfort in various viewing positions and lighting conditions. This is particularly useful when using the monitor in different environments or with varying desk setups, enhancing its usability.

Pivot Function

The absence of a pivot function limits its usability for tasks like reading long documents or coding, where a vertical screen orientation can be beneficial. Users who frequently work with vertically oriented content may find this limitation inconvenient, as it reduces the screen space available for such tasks.

VESA Mount Compatibility Function

The lack of VESA mount compatibility limits its flexibility in terms of mounting options, restricting it to desk or stand use without the possibility of wall mounting or monitor arm attachment. This can be a drawback for users who prefer a clean and organized workspace or need to mount the monitor for ergonomic reasons.
