To enhance the visual appeal and eliminate distractions caused by thick bezels, manufacturers are continuously reducing the bezel size on each display. This reduction ensures a seamless integration when tiling two displays together, minimizing the bezel-to-bezel gap. The result is a visually stunning video wall that captivates the attention of viewers, allowing content to flow smoothly across the entire display, providing an uninterrupted and immersive viewing experience.

3.5mm Non-even bezel and even bezel

“The narrower the width of the bezel-to-bezel gap, the more impactful experience you can create.” Currently, mainstream video walls have a bezel-to-bezel width of 3.5mm, striking a balance between price and performance. However, upon closer inspection, you’ll notice that the top and left bezels are thicker, measuring 2.5mm, while the right and bottom bezels are slimmer at 1mm. This design allows for a combined bezel-to-bezel width of 3.5mm when two displays are tiled together. The reason behind this asymmetry lies in the adoption of edge-lit LED backlight technology in LCD displays, which necessitates space for LED arrays.

In the market, you can also find displays with bezel-to-bezel widths of less than 1mm or even completely bezel-less displays. However, these options come with a relatively higher price tag.

Size and Aspect Ratio

The size and aspect ratio of your video wall displays are critical factors that depend on several considerations, including available space, viewing distance, and most importantly, how you plan to present content.

Ensuring the appropriate size is vital to achieve the desired impact and ensure optimal visibility. Begin by evaluating the dimensions of the installation area and calculating the viewing distance to determine the ideal display size.

46'' 2 x 2 video wall equals to 92'', and 55'' 2 x 2 video wall equals to 110''

Currently, two main sizes and aspect ratios dominate the market for video wall displays: 46” and 55” with a 16:9 aspect ratio. If you intend to create a video wall of less than 100” in a 2 x 2 configuration, the 46” displays would be the suitable choice.

Regarding the aspect ratio of the video wall, it should be determined based on the content format and how you plan to present the content. The aspect ratio will influence the overall visual experience and should align with the content’s intended presentation style.

Display Resolution

The resolution of your video wall has a significant impact on the visual quality and clarity of the content displayed. Higher resolutions, such as Full HD (1920×1080) and 4K Ultra HD (3840×2160), are particularly crucial when showcasing fine details or text, as they provide sharper and more detailed images.

By opting for higher resolutions, you get more pixels per inch, resulting in a crisper and more immersive visual experience. While most ultra-narrow video wall displays come with a resolution of 1920×1080, you can still transmit 4K content to a 2 x 2 video wall using HDMI 2.0 or DisplayPort 1.2.

If you wish to present content in 8K resolution, you’ll need to utilize external 8K controllers or graphic cards to handle the processing power required for such high-resolution content. It’s essential to assess your content needs and budget carefully to find the optimal resolution for your video wall setup.

Brightness and Color Accuracy

The brightness level and color accuracy of your video wall displays play a pivotal role in ensuring that your content stands out and captivates viewers’ attention. It is imperative to consider the lighting conditions in the installation area and select displays with ample brightness to maintain a powerful visual impact.

Brightness is typically measured in nits, and higher values guarantee clearer visibility, especially in well-lit environments such as shopping malls, indoor public areas, and transportation hubs. Look for displays with brightness levels ranging from 500 to 700 nits, although specific requirements may vary based on ambient lighting conditions.

Furthermore, when assembling multiple panels to create the video wall, achieving color accuracy and uniformity becomes crucial for a seamless visual experience across the entire display. Each panel may exhibit slight color differences due to mass production tolerance rates. If there is no pre-calibration process at the factory before shipping to the market, the video wall may appear inconsistent in uniformity.

Over time, the color performance may gradually degrade due to liquid crystal movement lag. Therefore, it is essential to have the displays calibrated to ensure consistent and vibrant visuals, even after extended usage. Proper calibration not only maintains the overall quality of the video wall but also guarantees a more pleasing and immersive viewing experience for your audience.

Connectivity and Control

Seamless integration and user-friendliness are key aspects to consider when setting up a video wall, and the connectivity options and control features of the displays play a vital role in achieving this. It is essential to carefully assess the available input and output ports on the displays, such as HDMI, DisplayPort, and VGA, as they allow you to connect various video sources.

In addition to these standard connections, incorporating “Must-have” features like RS232 protocol, LAN function, and Infrared Remote (IR) is crucial for efficient maintenance and control functions.

To simplify cabling and synchronization of multiple screens, it’s beneficial to opt for displays with daisy-chaining functionality, which can be achieved through DVI or DisplayPort. This capability enables you to connect displays in a series, reducing wiring complexity and streamlining video wall management.
