The device is best suited for AV integrators, digital signage installers, and small control rooms that want a straightforward way to split a single HDMI or DVI source into a 2x2 video wall or several single-row\/column configurations. Its biggest selling point is the combination of 4 HDMI outputs, 4K input support and multiple splicing modes that make physical screen layouts easy to change without complex configuration.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4 HDMI outputs:\u003c\/strong\u003e Sends a single HDMI or DVI source to four independent displays to build a large stitched image or alternate layouts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4K input support:\u003c\/strong\u003e Accepts up to 3840x2160P@24\/30Hz input while outputting full HD 1920x1080P@60Hz for each screen.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEight splicing modes:\u003c\/strong\u003e Choose 2x2, 1x1, 1x2, 1x3, 1x4, 2x1, 3x1 or 4x1 layouts to suit different wall arrangements.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e180 degree rotation:\u003c\/strong\u003e Rotation is supported in seven splicing modes so two outputs can be flipped 180 degrees for unusual mounting or rear-projection setups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAudio and control:\u003c\/strong\u003e Offers 5.1CH optical audio output and RS232 control for integration with AV control systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable build:\u003c\/strong\u003e Metal housing with gold-plated interfaces reduces interference and improves signal stability over time.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe controller is aimed at small to medium digital signage projects, trade show booths, point-of-sale video walls, and meeting rooms where a single high-resolution source must be split across multiple screens.

It is best for digital signage and small video walls where each panel at 1080p is acceptable, and where RS232 control and optical audio are helpful. For projects that require native 4K per output or advanced processing, a higher-tier processor will be more appropriate, but for its price and purpose this unit delivers dependable performance.\u003c\/p\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eCan this unit accept a 4K input?\u003c\/strong\u003e\u003cbr\u003eYes, it accepts 3840x2160P@24\/30Hz input but outputs are limited to 1920x1080P@60Hz per screen.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes it include a remote and power adapter?\u003c\/strong\u003e\u003cbr\u003eYes, the package includes an infrared remote control and a 5V\/2A power adapter; note the remote requires AAA battery which is not included.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan all outputs be rotated 180 degrees?\u003c\/strong\u003e\u003cbr\u003eNo, rotation is supported in seven splicing modes but only certain outputs (output 1 and output 2) can be flipped 180 degrees per the product limitations.\u003c\/p\u003e","brand":"GGrozza","offers":[{"title":"Default Title","offer_id":48689367941339,"sku":"B0C4XQ553C","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0724\/1043\/1707\/files\/71yeBzFni9L._AC_SL1500.jpg?v=1778624993","url":"https:\/\/gearmusthave.com\/products\/video-wall-controller-4k-2x2-tv-wall-processor-flexible-8-modes","provider":"GearMustHave","version":"1.0","type":"link"}
