Features

Built-in Speaker Function

Feature Description

A function that includes built-in speakers, allowing audio output directly from the monitor. This eliminates the need for external speakers, saving desk space and reducing cable clutter. Convenient for enjoying videos or casual listening without additional equipment.

About This Product

The product information does not specify whether built-in speakers are included. If absent, users will need to rely on external audio solutions, which may reduce portability and convenience, especially in settings where external speakers are not feasible.

Blue Light Reduction Function

Feature Description

A function that reduces the amount of blue light emitted from the screen. This can help reduce eye strain and fatigue, especially during long periods of use. Beneficial for users who spend many hours in front of the monitor.

About This Product

The product information does not mention a blue light reduction function. Without this feature, prolonged use may lead to increased eye strain and fatigue, particularly for users sensitive to blue light emissions. Consider using software-based blue light filters as an alternative.

Height Adjustment Function

Feature Description

A function that allows adjusting the height of the monitor stand. This enables users to position the screen at an ergonomic viewing angle, reducing neck and back strain. Useful for maintaining good posture and comfort during extended use.

About This Product

The product information does not mention height adjustment. The absence of height adjustment may lead to ergonomic issues if the monitor cannot be positioned at an optimal viewing angle, potentially causing neck or back strain during extended use.

Tilt Adjustment Function

Feature Description

A function that allows tilting the monitor screen forward or backward. This helps to optimize the viewing angle and reduce glare, improving visibility and comfort. Useful for different viewing positions and lighting conditions.

About This Product

The product information does not mention tilt adjustment. Without tilt adjustment, users may find it challenging to optimize the viewing angle and reduce glare, potentially affecting visibility and comfort in various lighting conditions and viewing positions.

Pivot Function

Feature Description

A function that allows rotating the monitor screen 90 degrees to a vertical orientation. This is particularly useful for tasks like reading long documents, coding, or web browsing. It maximizes screen space for vertically oriented content.

About This Product

The product information does not mention a 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 significantly enhance productivity and screen real estate utilization.

VESA Mount Compatibility Function

Feature Description

A function that allows mounting the monitor on a VESA-compatible wall mount or monitor arm. This frees up desk space and allows for flexible positioning of the monitor. Useful for creating a clean and organized workspace.

About This Product

The product information does not mention VESA mount compatibility. The lack of VESA mount compatibility restricts mounting options, limiting it to desk or stand use without the flexibility of wall mounting or monitor arm attachment, which can save desk space and improve ergonomics.

SHOPSTAFF Rating Score

#84

Ranked #84 out of 100 products in Category

3.3

Overall Rating

The KEFEYA Laptop Screen Extender offers a 2K resolution display, enhancing productivity with its dual-screen setup. While it provides good image quality and portability, the brand's reliability is uncertain. It's a budget-friendly option for users needing extra screen space on the go.

Screen Size and Resolution

4.3

Rating Criteria Explanation

The screen size and resolution determine the amount of visible content and the clarity of the image. For portable monitors, a 15-17 inch screen with a Full HD (1920x1080) resolution is generally ideal, balancing portability and usability. A larger screen might be more immersive, but reduces portability. Higher resolutions offer sharper images and more detail, but can strain your device's resources and may not be fully utilized on smaller screens. Consider your primary use case - if it's mostly for text editing or general productivity, Full HD is sufficient. For gaming or multimedia, consider higher resolutions if your device can support them.

Rating Comments

The 14-inch screen with 2160x1440 resolution offers a crisp and clear image, suitable for detailed work and multitasking. The smaller screen size enhances portability, making it convenient for on-the-go use, though some may prefer a larger display.

Refresh Rate and Response Time

2.5

Rating Criteria Explanation

Refresh rate (Hz) indicates how many times per second the monitor updates the image, while response time (ms) is how quickly a pixel can change colors. Gamers should prioritize a high refresh rate (144Hz or higher) and low response time (5ms or less) for smoother, more responsive gameplay with reduced motion blur. For general use, a 60Hz refresh rate is typically adequate. However, even for non-gaming tasks, a higher refresh rate can result in a more fluid and pleasant visual experience. A lower response time minimizes ghosting, which can be noticeable during fast-paced action.

Rating Comments

Since the refresh rate and response time are not specified, it's difficult to assess its suitability for gaming or fast-paced video. It is likely adequate for general productivity tasks, but may exhibit motion blur in more demanding applications.

Panel Type (IPS vs. TN vs. VA)

3.0

Rating Criteria Explanation

The panel type greatly affects color accuracy, viewing angles, and contrast ratio. IPS (In-Plane Switching) panels are known for their excellent color reproduction and wide viewing angles, making them suitable for tasks that require color accuracy, such as photo editing or graphic design. TN (Twisted Nematic) panels typically have faster response times, making them a popular choice for gaming, but often suffer from poorer color accuracy and narrower viewing angles. VA (Vertical Alignment) panels offer a compromise, providing better contrast ratios than IPS panels and faster response times than TN panels, though their color accuracy and viewing angles are generally not as good as IPS. For portable monitors, IPS is often preferred due to its versatility.

Rating Comments

The panel type is not specified, making it difficult to determine color accuracy and viewing angles. Without this information, it's hard to say if it's suitable for tasks requiring precise color reproduction or wide viewing angles.

Connectivity Options

4.3

Rating Criteria Explanation

Consider the available ports on the monitor. Common ports include HDMI and USB-C. HDMI is essential for connecting to laptops, PCs, and gaming consoles. USB-C is useful for both video signal and power delivery, simplifying connections and reducing cable clutter, especially if your device supports DisplayPort Alternate Mode (DP Alt Mode). Ensure the monitor has the necessary ports to connect to your devices without requiring adapters. Also, check if the monitor supports power delivery via USB-C, which allows you to power the monitor and charge your connected device simultaneously.

Rating Comments

The inclusion of both USB-C and HDMI ports provides versatile connectivity options, ensuring compatibility with a wide range of devices. This simplifies setup and reduces the need for adapters, enhancing convenience.

Brightness and Contrast Ratio

3.8

Rating Criteria Explanation

Brightness (measured in cd/m² or nits) determines how visible the screen is in different lighting conditions. A higher brightness is essential for using the monitor outdoors or in brightly lit environments. Contrast ratio is the difference between the darkest and brightest parts of the screen, affecting the depth and richness of the image. A higher contrast ratio results in more vivid colors and deeper blacks. Aim for a brightness of at least 250 cd/m² for comfortable indoor use and a contrast ratio of 1000:1 or higher for better image quality.

Rating Comments

With 300 nits brightness and a 1000:1 contrast ratio, the monitor offers decent image quality for indoor use. However, the brightness may be insufficient in brightly lit environments, potentially affecting visibility.

Built-in Speakers and Audio Output

2.0

Rating Criteria Explanation

While not critical, built-in speakers can be a convenient feature, especially for portable monitors used for entertainment or presentations. However, the audio quality of built-in speakers is often limited. Check if the monitor has a 3.5mm audio output jack, allowing you to connect headphones or external speakers for better audio quality. The presence of audio output becomes essential if you plan to use the monitor in environments where external speakers are desired or required.

Rating Comments

The presence or absence of built-in speakers is not specified. If it lacks built-in speakers, external speakers or headphones will be necessary for audio output, which may be inconvenient for some users.

Manufacturer Reliability and Warranty

2.5

Rating Criteria Explanation

The manufacturer's reputation for quality and reliability is crucial. Research the brand's track record for producing durable and long-lasting monitors. Check online reviews and forums to get insights into other users' experiences with the brand and specific models. A solid warranty provides peace of mind in case of defects or malfunctions. Look for monitors with at least a one-year warranty, and carefully review the warranty terms and conditions to understand what is covered and the process for making a claim. Established brands often have better customer support and repair services.

Rating Comments

Given the manufacturer's limited brand recognition, long-term reliability and warranty support are uncertain. Users should consider this when evaluating the overall value proposition and potential longevity of the product.

Cost Performance

4.0

Rating Criteria Explanation

Evaluate the monitor's features and performance relative to its price. Determine your budget and identify the features that are most important to you. Compare different models within your budget range, considering their specifications, features, and reviews. A more expensive monitor might offer better performance or more features, but it's important to ensure that the added benefits justify the higher cost. Look for deals and discounts to maximize your value. Consider the long-term cost of ownership, including power consumption and potential repair costs.

Rating Comments

At its price point, the KEFEYA monitor offers good value, providing a 2K display and essential connectivity options. However, the lack of certain specifications and the brand's uncertain reliability should be considered when making a purchase decision.
