No, this KVM switch supports a single monitor up to 8K@60Hz or dual monitors up to 4K@60Hz. It does not support a triple monitor setup.
Yes, an external power adapter is included and required for the KVM switch to operate, especially to provide the 60W USB-C Power Delivery.
The maximum resolution is 7680 x 4320 pixels (8K) at 60Hz for a single display, or 3840 x 2160 pixels (4K) at 60Hz for dual displays. Higher refresh rates like 4K@144Hz are supported with DSC (Display Stream Compression).
For full functionality, especially for 40Gbps data transfer and high-resolution video, it is highly recommended to use certified Thunderbolt 4 cables. For display output, ensure your USB-C cables support DisplayPort Alternate Mode.
Yes, all USB ports support BC 1.2 charging, providing up to 5V/2.4A, which is suitable for charging smartphones and other small USB-powered devices.
This KVM switch is designed to control up to three computers, sharing your display, keyboard, mouse, and other peripherals between them.
DisplayPort Alternate Mode (DP Alt Mode) allows a USB-C connection to carry DisplayPort video signals. This KVM switch relies on DP Alt Mode being supported by your computers to output video through its Thunderbolt 4 ports.
Verify that both the computer and the cable support DisplayPort Alternate Mode. Ensure the monitor and KVM switch are connected with compatible Thunderbolt 4 or USB-C cables. Try a different display cable or port. Confirm the selected computer's graphics drivers are up to date. For dual displays, ensure your system supports MST (Multi-Stream Transport).
Disconnect and reconnect the keyboard/mouse to the KVM switch. Ensure they are plugged into the correct USB Type-A ports. Try plugging them directly into the computer to check if the peripherals are functioning. Restart the computer after switching.
Confirm you are using Thunderbolt 4 cables for the fastest speeds. Ensure the connected devices and ports on both the computer and the KVM switch support 40Gbps. Check for any other high-bandwidth devices connected that might be sharing bandwidth.
Ensure your laptop supports USB Power Delivery (PD 3.0) and that the connected USB-C cable is capable of carrying sufficient power (at least 60W). Check that the KVM switch is powered by its AC adapter. The PD charging is delivered via the Thunderbolt 4 host ports.
Disconnect the power adapter from the KVM switch, wait for 10 seconds, and reconnect it. Ensure all connected Thunderbolt 4 cables are properly seated. Try connecting a different computer to rule out an issue with the source machine.
