Selecting the right KVM switch allows IT teams to streamline workflows, reduce desktop clutter, and manage multiple systems from a single console. Because a KVM must align with your video standards, USB requirements, and peripheral needs, choosing the correct model is essential to achieving reliable performance in production environments. Below are seven key considerations every IT professional should evaluate when selecting a StarTech.com hardware KVM. 1. Hardware KVMs Are Platform-Independent StarTech.com KVMs are hardware-based unless active functionality is explicitly stated. They rely on industry standards rather than software or drivers, allowing them to operate independently of operating systems. This design makes them compatible with a wide range of systems, including servers, workstations, laptops, small form factor devices, and many NVR or security platforms. Some models also support features such as keyboard hotkeys and independent peripheral switching, without requiring any software installation. For IT teams, this reduces configuration complexity and long-term support risk. 2. Start With Your Displays — They Drive Every Other Decision Display requirements should be the starting point for any KVM deployment. Confirm each monitor’s native resolution, maximum refresh rate, and available video inputs before selecting a KVM. For the most reliable experience, connect displays directly to the KVM. Adding adapters or converters between the KVM and the monitor can interfere with EDID communication and introduce signal stability issues. A direct connection helps ensure consistent video output across systems. 3. Plan All Required Computer Connections Each connected system typically requires multiple connections to the KVM one video cable per display and a USB or HID connection for keyboard and mouse control. Multi-monitor setups or specialized workflows may require additional video or audio links. When adapters are required, place them between the computer and the KVM rather than between the KVM and the display. This approach preserves signal integrity and simplifies troubleshooting. Always verify cable types, adapter direction, and resolution support. The accessories section on each StarTech.com KVM product page lists validated connection options. 4. Know Your Video Format, Each Behaves Differently Video standards vary significantly, and selecting the correct KVM depends on matching those behaviors to your environment. HDMI and DVI-D operate interchangeably at resolutions up to 1920 × 1200. DisplayPort supports higher resolutions and refresh rates but requires careful attention to version compatibility and cable quality. For non-DisplayPort sources, active converters are recommended. Dual-Link DVI-D remains the best option for high-resolution DVI deployments. VGA continues to be used in many industrial and legacy environments, though converting VGA to digital formats always requires an active converter to maintain signal reliability. 5. USB Isn’t Just USB — Device Behavior Matters Although USB is the standard interface for HID devices, not all peripherals behave the same way. The keyboard, mouse, or HID-labeled ports on a hardware KVM are designed for standard USB input devices. More complex peripherals, such as wireless keyboards, gaming keyboards, or devices with integrated hubs, may need to connect through the KVM’s general USB hub ports instead. High-bandwidth devices like webcams, touchscreens, or extenders may exceed USB limitations when routed through intermediate hardware, requiring direct connections or additional planning. 6. Confirm Additional Data Ports for Your Workflow Some KVM models include legacy or supplementary data connections, such as PS/2, serial, or audio switching. These ports are often critical in environments that rely on older control systems or require synchronized audio routing. Before deployment, verify that the KVM includes the specific data connections your equipment and workflows depend on. 7. Use the Correct Console or Combo Cables Many KVMs, especially VGA-based models, use proprietary console or combo cables that split into video and USB or PS/2 connections on the computer side. These cables are not interchangeable across models. Using an incorrect console cable can prevent the KVM from functioning properly. Always use the specific cable model recommended for your KVM to ensure full compatibility and reliable operation. Choose a KVM Built for Your Environment The right KVM simplifies system management, delivers consistent performance, and helps IT teams maintain clean, efficient workspaces. By starting with display requirements, mapping out all system connections, and selecting compatible video and USB accessories, you can deploy a KVM solution that remains reliable over time.
