• Video interfaces include VGA, HDMI, DVI, and DisplayPort, with resolutions ranging from 1280x1024 up to 4K at 60Hz . Form Factor and Mounting:
• Most units are 1U rack-mountable, saving space in server racks. Some include integrated LCD consoles with foldable drawers for compact deployment . Switching Methods:
• Switching between computers can be done via front-panel push-buttons, hotkeys, or on-screen display (OSD). Auto-scan modes are available for sequential monitoring . Peripheral Sharing and USB Hubs:
• Many models include built-in USB hubs (2–4 ports) to share devices across connected computers. USB 2.0 and 3.0 support is common, with backward compatibility for older devices . Compatibility:
• Works with Windows, macOS, Linux, and Sun systems. Some models are TAA-compliant for federal procurement . Additional Features:
• Audio support with stereo or 2.1-channel output

2. Video resolution and interface – ensure compatibility with your monitors and desired resolution.
3. USB hub requirements – if sharing peripherals, select a model with built-in USB ports.
4. Rack space – most switches are 1U, but integrated LCD consoles may require additional depth.
5. Budget and warranty – prices range from $100 for basic 4-port units to over $1,500 for high-end integrated consoles, with warranties typically 1–3 years . USB-compatible rack-mounted KVM switches provide a centralized, efficient, and scalable solution for managing multiple servers or computers, making them ideal for data centers, server rooms, and IT labs.
