Video wall monitors typically use LCD panels model specifically classed as being for video walls, the main characteristic of these being very narrow bezels, currently as thin as 0.9mm. Furthermore, there are specific video wall functions such as daisy-chain & scaling and calibration together with any application specific requirements for input signals and color settings.
Digital View has three LCD controller board models with specific video wall functionality suitable for making video wall monitors:
- SVX-4096-VW: Signal daisy-chain, 4K input with video wall scaling, calibration support.
- SVX-2560: 4K input with video wall scaling, calibration support.
- SVX-1920v3: Full-HD input with video wall scaling, calibration support.
Most video wall panels on the market are 1920×1080 resolution so a 2×2 video wall will have 4K (3840×2160) resolution. However to show 4K across a 2×2 video wall requires that either the signal source is matched to the panel or the monitor is able to accept 4K and scale appropriately (the SVX-4096-VW and SVX-2560 can do this).
Here is an exploded view of a video wall monitor design available from Digital View, a complete sample kit would also include other parts such as cables and power supply:
LCD based video walls can be almost any size with various ways to connect input sources to maximize resolution and functionality while keeping costs down. For example a single 4K input can be daisy-chained to all video wall monitors or groups of video wall monitors can be connected to multiple video sources such as:
The main video wall LCD panel manufacturers available outside Asia include AUO and LG Display and Samsung Display with panel sizes of 46″, 49″, 50″, 55″ and recently announced 65″. Other characteristics such as brightness (500~800nit) and surface finish (2% to 44% haze) are also a consideration.
