\nFirst standardized by the cinema market, 4K resolution<\/strong> has quickly risen in popularity to become the preferred choice for a variety of viewing applications. Consumer televisions, digital signage, visualization and simulation, entertainment, and medical imaging are just a few markets where the higher pixel density and enhanced detail of 4K resolution has proven advantageous.
\nHowever, when it comes to control room video walls<\/strong> for security and monitoring, 4K resolution is simply not the right choice. Let\u2019s explore why.
\nDriving interest in 4K for control rooms
\n<\/strong>The interest in 4K resolution for control rooms is being driven from two areas: ingest of content and desktop forensic analysis. Developments in high-resolution capture and streaming equipment, such as 12MP cameras and high-bandwidth networking, give control room operators the ability to view and manage high-resolution content. Higher resolutions allow for more details to be perceivable and, for certain applications, this is necessary.
\nFor example, 4K displays allow operators conducting forensic-level analysis to clearly perceive fine details, like license plates or a person\u2019s face. The benefits of this level of detail in security settings are obvious. However, when we look at the typical large-format control room video wall, 4K resolution is not only unnecessary, it actually limits the viewer\u2019s ability to properly evaluate displayed content.
\n4K video walls: Getting lost in the details
\n<\/strong>It\u2019s possible to have too much detail. When we display 4K content on a 4K video wall, certain aspects of the image show up very small. Content like fonts, labels on maps, SCADA images, dashboards, web pages and other fine-detail objects appear so small they are illegible. This is due to what the human eye can interpret based on distance and the type of content displayed.
\nOptimal viewing for 4K resolution is up-close on a smaller display, such as a desktop monitor at an operator\u2019s console. However, when viewing content on a video wall where the control room operators are sitting back from the display, certain types of images in 4K resolution become unreadable. Add to this the common practice of displaying multiple sources across the entire video wall, and the issue is compounded.
\nHD: The best choice for control room video walls
\n<\/strong>With decades of experience as a leading supplier of control room solutions, Christie<\/strong><\/a> understands which products work best in any control room environment. When specifying a video wall for a partner or customer, they\u2019re often surprised when we suggest HD video walls<\/strong> as the preferred choice for a better, more legible viewing experience.
\nMost commercial-grade, 1080P HD display products, such as tiled-LCD or LED video walls, provide more than enough resolution for the modern control room environment. Not only do HD video walls provide a better user experience, they are also much less expensive than their 4K counterparts. As an added bonus, operators can still use their high-resolution cameras. This is because Christie display products can scale native 4K content to properly fit HD displays.
\nThis means control rooms can still use a 4K workflow for fine-detail desktop analysis when needed, while benefiting from a better viewing experience when interacting with the video wall. And of course, operators can always group four HD sources together into a single window on the video wall to display native 4K content.
