LCD displays which controlled by 4K video wall controller are built for a wide range of uses, from commercial TV displays to video walls, digital signage, billboards, and sports arenas. The clarity in any one of those use cases depends on the display’s pixel density. It’s important to remember that pixel pitch correlates directly to the size of your display and the optimal viewing distance of employees, operators, and decision makers.

Choosing the right 4K video wall controller for your application is critical to deploying a successfull LCD display. There are many factors and specifications to consider before selecting a controller. Below are several questions to ask to help you select the best LCD video wall controller.

How many inputs are required? And/or is switching of inputs required?

The number of inputs and ability to switch inputs is heavily dependent on your specific application. Each 4K video wall controller has a specified number of inputs it can handle. If you plan on switching inputs frequently, other considerations will need to be made.

How many 4K video wall controllers will be necessary?

There’s never a single answer to this question. Each display’s 4K video wall controller count is calculated by a myriad of different factors such as:

The resolution of the display

How many individual panels can be controlled by a single output port on the 4K video wall controller

How many total panels (or pixels) make up the video wall

How many output ports are available on the 4K video wall controller

How is the content displayed with 4K video wall controller?

Another example of why BeingHD’s 4K video wall controller is best for your video wall. There are generally two types of methods for displaying content on video walls due to the standard and non-standard aspect ratios and pixel pitches allowable with direct-view.

Point to Point (Pixel to Pixel)

Point to Point provides the best quality image, while scaled content can experience artifacting. If your content will be Point to Point, the 4K video wall controller specifications should match the source resolution. (Depending on the size of your display and number of source feeds, it might require multiple 4K video wall controllers.) For much larger video wall displays, where pixel counts are much larger than standard resolutions, splicing multiple images or video segments together at standard resolutions also produces a very high-quality final image on the display. Splicing requires a content playback engine that can create a layout that is the same size as the display and splice that layout into multiple segments of standard resolution outputs to individual 4K video wall controllers.

Scaled

If the video wall resolutions are close to standard resolutions, or you’re stuck with a standard resolution and a non-standard aspect ratio display, scaling may be the easiest, most cost-effective option. Scaling and cropping content to fit into the dispaly may create other considerations like image quality degradation and placement of important data within visible areas of the display (if the video wall is a non-standard aspect ratio).

BeingHD’s 4K Video Wall controller is designed to be a truly capture, AD convert, route, distribute all-format signal to the video wall(LCD displays), while maintaining a true digital signal.

BeingHD’s 4K Video Wall controller with many different video interfaces, 4K Video Wall include 2 HD inputs with 4K30 resolution and 4 HD outputs with 1080P resolution. 4K Video Wall spports different Video Wall modes, 1x2, 1x3, 1x4, 2x2 etc, with the 4K input and 1080P output, BeingHD’s 4K Video Wall controller can realize the point to point display. 

As time goes the 4K Video wall controller in big walls or the big image of video walls are widely used all over the world in multiple application areas. Such project as show rooms, board rooms, public displays, university halls, lecture rooms, conference centers, traffic control centers, police supervision centers, utility supervision rooms, security supervision rooms, industrial control and supervision centers or even mission critical control rooms need more information and a single monitor screen is not enough. Contact BeingHD today and we’ll help you select which 4K video wall controller is best for your application.
