Lưu ý quan trọng khi thiết lập:

• Ensure each computer supports dual-monitor display. Test by connecting monitors directly to your computer before using the KVM switch.
• Each computer requires one DisplayPort cable and one USB-A cable connected to the KVM switch for full functionality (video, keyboard, mouse).
• Both your computer and monitors must support 4K@60Hz, and you must use appropriate cables, to achieve 4K@60Hz resolution.
• Do not press the switch button while connecting devices or cables to prevent potential issues.
• The two monitors will display the video source from only one computer at a time; simultaneous output from both PC1 and PC2 is not supported.
