When your conference all-in-one device experiences unresponsive touch controls, non-functional remote controls, or inability to connect with other devices, it can severely impact meeting efficiency. Please don’t worry—most issues can be resolved by following the steps below. Refer to this guide and troubleshoot from simple to complex.
1. What to do if the touch screen is unresponsive or inaccurate?
Start with basic checks
Clean the screen: Use a soft, dry cloth to wipe the screen, ensuring there is no dust, grease, or moisture.
Check the screen protector: If a third-party screen protector is applied, try removing it to see if touch responsiveness improves.
Restart the device: Fully power off the conference all-in-one, wait for one minute, and then turn it back on. This is the most effective way to resolve temporary software issues.
Calibrate the screen
If basic checks don’t help, the screen may need calibration.
Go to [Settings] > [Display] or [Touch Screen] in the device menu.
Find the "Touch Calibration" or "Position Calibration" option.
Follow the on-screen prompts and accurately tap the indicated points to complete the calibration process.
Check for system updates
Outdated system software may contain bugs. Go to [Settings] > [About Device] > [System Update] to check for and install any available updates.
2. What to do if the remote control or software cannot control the device?
Remote control not working
Replace the batteries: This is the most common cause. Try replacing the batteries with new ones first.
Re-pair the remote: For Bluetooth remotes, refer to the user manual to re-pair (usually by holding a specific key combination).
Avoid interference: Ensure there are no obstructions between the remote and the device, and keep it away from strong light sources.
Phone/computer control software cannot connect
Check the network: Ensure both the controlling device and the conference all-in-one are connected to the same Wi-Fi network.
Confirm device information: In the control software, enter the correct IP address or device ID displayed on the conference all-in-one. The IP address can be found in [Settings] > [Network].
Update the software: Ensure the control app on your phone or computer is updated to the latest version.
3. What to do if screen mirroring fails or external devices cannot connect?
Wireless screen mirroring fails
Select the correct signal source: On the conference all-in-one, use the remote or side buttons to switch the signal source to "Wireless Screen Mirroring" mode.
Use the correct operation:
Windows PC: Press
Win + Kand select the name of your conference all-in-one.Apple devices: Use the "Screen Mirroring" function.
Restart the network: If the connection is unstable, try restarting the router and the conference all-in-one.
External devices (e.g., speakers, cameras) not responding
Check the connections: Ensure HDMI, USB, and other cables are securely plugged in and not loose or damaged.
Check the power supply: Ensure external devices (e.g., speakers) are powered on.
Check the signal source: For wired connections (e.g., HDMI screen mirroring from a PC), switch the conference all-in-one’s signal source to the corresponding input (e.g., HDMI 1).
