3X3 Video wall controller
HDMI 1.4 vs HDMI 2.0
The main attraction to HDMI v2.0 is 4K 60Hz support which is a big improvement over v1.4’s 4K 30Hz standard. Improving frame rate at first might not seem like such a big deal, but twice the video bandwidth is required since it is sending twice the number of frames per second.
4K 30Hz vs 4K 60Hz
As our TVs get bigger and bigger, so does the perceived difference between refresh rates.
As you know, video is simply a bunch of images played rapidly to give the illusion of movement. More images viewed per second equates to more-realistic video. Refresh Rates (measured in Hz) are what is used to describe the number of unique images played per second. 30 Hz means that you’re seeing 30 unique images per second while 60Hz doubles the number of images per second.
What is the video wall controller? why do we need it?
A video wall controller captures content “inputs” from your desired sources (like computers, cameras, and cable boxes) and gathers them in a single control platform. In response to your real-time commands, the controller routes selected content to the desired regions of a video wall or display. The controller may also provide additional scaling or processing to manipulate the appearance and behavior of your content.
For any application that requires switching between multiple content sources, displaying content larger than HD, or any kind of real-time interactivity, you’ll need a video wall controller.
