Impressive image quality with 4K support
The video switch maintains 4K Ultra-HD picture quality while switching between content from HDMI source devices - including Blu-ray™ players or DVD players, computer systems, video game consoles, digital cable and satellite boxes and A/V receivers.
4K support ensures a higher level of image clarity and visibility, delivering four times the resolution of 1080p - 8.29 million pixels versus 2.07 million pixels. It provides a more engaging visual experience for audiences in a wide range of venues including conference centers and boardrooms, home theaters, and commercial settings. With its exceptional resolution and image quality, it's also ideal for bringing your digital signage to life.
Fast and easy operation
Enjoy hassle-free operation with three switching modes:
• Fast auto-switching: ensures minimal time for switching between HDMI sources. The switch provides effortless operation with advanced auto-sensing - it detects the latest connected HDMI source and automatically switches to it. Auto-switching encourages collaboration among colleagues, by making it easy to share your projector. It also ensures no downtime in a digital signage application if a source signal is accidentally powered off or fails.
• Priority switching: identifies one port to take first priority for HDMI sources when multiple sources are connected, ideal for applications such as digital signage.
• Manual switching: enables you to manually select your HDMI source with front-panel buttons that are easy to use.
An IR remote control is included in the box, enabling you to select your desired input source remotely. The RS-232 serial control interface ensures easy remote operation with serial control enabled devices.
Hassle-free setup with plug-and-play installation
The switch also saves time during setup with EDID emulation, which ensures that all of your display settings, such as native resolution and refresh rate, are communicated between your display and video source devices. EDID emulation maximizes compatibility with your 4K display to ensure a convenient plug-and-play installation and the sharpest image quality.
• Share a 4K television or projector with four different 4K video sources to create a powerful visual experience in boardrooms, classrooms, home theaters, hotels, shopping malls, health centers and many other environments
• Collaborate easily with colleagues by connecting multiple users to the same display, and switch between input devices
• Enhance your home theater by connecting four A/V devices to your television, such as Blu-ray players, cable and satellite set-top boxes, and computers
• Ideal in digital signage applications - the switch is backward compatible with high-definition 1080p, so any video source will look great in your digital signage
