IMPORTANT TIPS!!! PLEASE READ BEFORE ORDER!!!

1. Dual monitor display requires 2 HDMI connection from each computer, however, most computers especially laptops do not have dual HDMI outputs, thus reliable adapters or docking station will be needed but not included for non-HDMI video ports like DisplayPort, USB C, DVI and VGA. Please be aware of the adapters needed for your computers before ordering it, or reach out CKL support for recommendations.
2. HDMI Monitors are preferred to avoid adapters being used on both computer side and monitor side which will probably cause display issue.
3. VGA to HDMI, HDMI to VGA and HDMI to DisplayPort adapters need to be at least USB powered, DisplayPort adapter needs to be active type. Simple video conversion cables are not recommended due to most simple conversion cable does not have built-in chips for reliable performance, they may work directly with computers, but may not work through the KVM switch; Resolution relies on adapters and docking stations as well.
4. Some keyboards and mice with special features like back lights, trackballs, gaming, mechanical, razar etc. may not work well on the USB keyboard and mouse ports which are dedicated for hotkeys, the workarounds are to turn off the hotkeys or plug them into USB 3.0 HUB ports.
5. If you have any assistance needed while setting up or using our products, please do not hesitate to reach out for CKL support.
