Full Product Description

Create a Stunning Visual Experience with the Ultimate Video Wall Processor

Are you trying to create a professional large-format display without the massive cost of industrial screens? The 2x2 HDMI Video Wall Controller is your answer. Whether you are running a sports bar, setting up a digital storefront, or building a dedicated control room, this processor bridges the gap between consumer TVs and professional digital signage.

Seamless Splicing with Bezel Correction

One of the biggest pain points in DIY video walls is the thick gap created by monitor bezels. Our controller solves this with a dedicated 180° Rotation Function. By flipping the top two screens (Output 1 & 2) upside down, you can mount the monitors so their thinnest edges meet in the center. This significantly reduces the "black bar" effect, creating a cohesive and comfortable visual flow.

Versatile Display Modes for Any Scenario

You aren't limited to just a 2x2 square. This processor supports 8 distinct display modes (including 1x2, 1x3, 1x4, 4x1, and more), allowing you to arrange screens horizontally for a stock ticker or vertically for digital advertising posters.

Professional Audio & Control Integration

Unlike basic splitters, this unit separates audio for a premium sound experience. Connect external sound systems via the 3.5mm analog or Optical SPDIF ports (supports 5.1CH). Plus, with RS232 support and an included IR remote, integrating this device into a professional AV rack is effortless.

FAQ Section

Q: Can I use 4K screens with this controller?
A: Yes, you can use 4K screens, but please note that the controller's output is capped at 1080p@60Hz per screen. For the best performance and to ensure the rotation function works correctly, we recommend setting your TV/Monitor settings to 1080p.

Q: How does the 180-degree rotation help with the borders?
A: Standard TVs have thicker bezels at the bottom (for the logo/speakers). By rotating the top two TVs 180 degrees (upside down), the thin top bezels of the bottom TVs meet the thin top bezels of the inverted top TVs. This dramatically thins the "crosshair" line in the middle of your 2x2 video wall.

Q: Does this work with gaming consoles like PS5 or Xbox?
A: Absolutely. It is compatible with any HDMI source, including PS5, Xbox, Roku, and PC. For gaming, we highly recommend the 2x2 mode for the most immersive field of view.
