4. Setup Instructions
Follow these steps to set up your llano HDMI 2.1 Switcher:
- Power Connection: Connect the provided USB-C power cable to the DC 5V port on the switch. Connect the other end of the USB-C cable to a suitable USB power adapter (e.g., a 5V/2A phone charger, not included). Ensure the switch receives stable power.
- Input Device Connection: Connect your HDMI source devices (such as gaming consoles like PS5 or Xbox, Blu-ray players, PCs, or streaming devices) to the HDMI INPUT 1, INPUT 2, INPUT 3, and INPUT 4/ARC ports on the switch. Use high-quality HDMI 2.1 compatible cables for optimal performance.
- Output Display Connection: Connect your television, monitor, or projector to the HDMI OUTPUT port on the switch. Again, use an HDMI 2.1 compatible cable.
- ARC Connection (Optional): If you intend to use the Audio Return Channel (ARC) feature, ensure your television and audio receiver both support ARC. Connect an HDMI cable from your TV's ARC-enabled HDMI port to the INPUT 4/ARC port on the switch. Note that only this specific input port supports ARC functionality.

5. Operating Instructions
The llano HDMI 2.1 Switcher offers multiple ways to select your desired input source:
- Manual Switching: Press the 'SELECT' button located on the front panel of the switch to cycle through the connected HDMI input sources (Input 1, 2, 3, 4). The corresponding LED indicator will light up to show the active input.
- IR Remote Control: Use the included IR remote control to directly select an input source. Press the '1', '2', '3', or '4' button on the remote to switch to the respective HDMI input. Ensure there is a clear line of sight between the remote and the IR receiver on the switch for proper operation.
- Automatic Switching (CEC): The switch supports Consumer Electronics Control (CEC). When a connected HDMI source device is powered on or begins playback, the switch may automatically detect the active signal and switch to that input. This functionality depends on the CEC compatibility and settings of your connected devices.
- Indicator Lights: Observe the LED indicators on the front panel to identify the currently active input source.

7. Troubleshooting
If you encounter issues with your llano HDMI 2.1 Switcher, refer to the following common troubleshooting steps:
- No Video/Audio Output:
- Ensure all HDMI cables are securely connected to both the source devices, the switch, and the display.
- Verify that the correct input source is selected on the switch (check LED indicators).
- Confirm that the switch is receiving power from the USB-C power cable and adapter.
- Test with different HDMI cables, especially high-quality HDMI 2.1 certified cables, as lower quality cables may not support high resolutions/refresh rates.
- Bypass the switch and connect the source device directly to the display to confirm the source device and display are functioning correctly.
- Flickering Screen or Intermittent Signal:
- This can often be caused by cable quality. Replace HDMI cables with certified HDMI 2.1 cables.
- Ensure the power supply is stable and sufficient.
- Reduce the resolution or refresh rate of the source device to see if the issue persists.
- IR Remote Control Not Responding:
- Check and replace the battery in the remote control.
- Ensure there are no obstructions between the remote and the IR receiver on the switch.
- Note that the effective range of the remote control may be limited.
- ARC (Audio Return Channel) Not Functioning:
- Confirm that both your TV and audio receiver are ARC-enabled and that ARC is activated in their respective settings.
- Ensure the HDMI cable is connected to the INPUT 4/ARC port on the switch and the designated ARC HDMI port on your TV.
- Some TV brands (e.g., Sony) may have specific ARC compatibility considerations with external switches. Consult your TV's manual.
- Automatic Switching (CEC) Issues:
- CEC functionality can be inconsistent across different brands and devices. Ensure CEC is enabled on all connected devices.
- Try disabling and re-enabling CEC on your devices and the switch (if applicable).
