8. Řešení problémů

Pokud narazíte na problémy s přepínačem KVM, podívejte se na následující běžné problémy a jejich řešení:

Problém	Možná příčina / řešení
Žádné zobrazení na monitoru	Ensure all HDMI cables are securely connected to both the KVM switch and the PCs/monitor. Ověřte, zda je monitor zapnutý a nastavený na správný vstupní zdroj. Try switching to the other PC input to confirm the KVM switch is functioning. Check if the resolution and refresh rate of your PCs are supported by the KVM switch (max 4K@30Hz). If using an optional power adapter, ensure it is connected and providing power.

Some advanced keyboard/mouse features (e.g., custom macros, extra buttons) may not be fully supported through KVM hotkeys. Try using standard USB ports on the KVM switch if available. Check PC power management settings for USB ports (e.g., disable USB selective suspend).
USB peripherals (front port) not working	Ensure the peripheral is properly connected to the front USB 2.0 port. Verify the KVM switch has sufficient power. An optional 9V/DC power adapter may be needed for high-power USB devices. Confirm the peripheral is compatible with USB 2.0.
Žádný zvuk nebo zkreslený zvuk	Check all 3.5mm audio cables are securely connected to the KVM switch and your audio devices/PCs. Ensure the correct audio output/input device is selected in your PC's sound settings. Verify volume levels on both your PC and audio devices.
KVM switch not responding or freezing	Press the RST (Reset) button on the front panel. Disconnect and reconnect the USB cables from the PCs to the KVM switch. Ensure stable power supply. If issues persist, consider using an optional 9V/DC power adapter.
Beeping sound upon switching	This is often a normal operational sound indicating a successful switch. Consult the Quick Installation Guide for information on disabling beeping, if such a feature exists for this model.
