Your computer display screen might appear different depending on the manufacturer and your operating system. Consult your computer’s instructional manual on how to connect to an external display. If a vertical and horizontal frequency-select mode exists, select 60Hz (vertical) and 67.5KHz(horizontal). In some cases, abnormal signals (such as stripes) might appear on the screen when the computer power is turned off (or if the computer is disconnected). If this is the case, press the [INPUT SOURCE] button to enter the video mode and supply an active signal. The display timings conform to VESA and CTA standards. For 4:3 content, the screen will display them in the center of the screen and maintain a 4:3 aspect ratio. The optimal vertical frequency for each mode is 60Hz.

Troubleshooting Common Problems General Problem or Issue Possible Solutions Remote Control is not working Check whether something is obstructing the display’s remote control receiver. Check whether the battery polarities in the remote control are installed correctly. Check whether the batteries need to be replaced. The unit turns off unexpectedly Check whether Sleep mode is enabled. Check if there is a power outage in your area. Turn on the display, provide an active signal, and see if the problem is with the signal or external control system. The power indicator is off, and there is no response Ensure the power cable is connected and not loose. Check that the power outlet is functioning properly and meets the required electrical requirement. The display does not recognize the USB storage device Ensure the drive is either formatted for FAT32 or NTFS. If the USB storage device needs external power, connect its power adapter to an electrical outlet. Video Not Working Properly Problem or Issue Possible Solutions No picture / No sound Check the Power status. Check the signal cable. Use the remote control to ensure the input source setting is the same as the connected device. Picture is unclear or cuts in and out Check the signal cable. Check if other electronics or different signal types are interrupting the signal. An optional active video cable or optional video extender is required for a long distance source. Poor picture quality Adjust chroma and/or brightness settings in the menu. Check the signal cable. Use the display’s native resolution for the source. Audio Not Working Properly Problem or Issue Possible Solutions No sound Press the Mute/Unmute button. Adjust the volume. Check the audio cable connection (if used). If using a computer digital video with embedded audio, ensure the computer speakers are set to external speakers. One speaker only Adjust the sound balance in the menu. Check the left and right sound control panel settings of the computer or media player source. Check the audio cable connection (if used). Ensure the content has two audio channels and not mono. Module Brightness Calibration Maintaining the LED Display General Precautions The LED lights used in the modules are susceptible to ESD (Electrostatic discharge). To prevent damage to the LED lights, do not touch them with bare hands or with conductive materials when handling. It is recommended to regularly inspect all installed components. Do not bring objects close to the ventilation holes of the display. Burns or personal injuries may occur if any body parts are brought too close. Be sure to power off and disconnect all cables before moving the display. Moving the display with its cables attached may damage the cables and thus cause fire or electric shock. Power off and disconnect the power plug from the wall outlet as a safety precaution before performing any type of cleaning or maintenance. Initial Operation If a new screen has been stowed for less than three (3) months, it can be used at normal brightness during its first use. If a new screen has been stowed for more than three (3) months, the brightness should be set at 30% for its first use and allowed to operate for two (2) hours continuously. After two (2) hours of use, power off for 30 minutes. The new screen is now ready for normal brightness usage. Front Panel Cleaning Instructions Use cool, compressed air to remove dust when the power is off. If the dust cannot be removed, the LED module should be replaced. Do not scratch and do not put pressure on the panel surface with fingers or any abrasive object. Do not use volatile substances such as sprays, solvents, or thinners. Cabinet Cleaning Instructions Do not allow water or detergent to come into contact with the surface of the display. If water or moisture gets inside the unit, a system malfunction or electrical shock may occur. Do not scratch and do not put pressure on the cabinet with any abrasive objects of any kind. Do not use volatile substances such as sprays, solvents, or thinners on the cabinet. Do not place anything made from rubber or PVC near the cabinet for any extended periods of time.
