ENGLISH 27 •• The PC BIOS configuration screen is not displayed correctly. -- On some PCs, the BIOS configuration screen may not display correctly because the 58:9 aspect ratio is not supported before the graphics card driver is configured. This is not a problem of the product; it is due to the design of the graphics card's BIOS configuration screen aspect ratio. To access the PC BIOS configuration screen, please connect a standard aspect ratio (4:3 or 16:9) monitor, then perform the BIOS configuration. Issues Related to Screen (Color) •• Screen has poor color resolution (16 colors). -- Use PC settings to set the color to 24 bits (True Color) or above. •• Screen color is unstable or mono-colored. -- Check the connection status of the signal cable. Or, re-insert the PC graphics card. •• I see dark or bright spots on the screen. -- Some pixels (red, green, blue, black) are visible on the screen due to the unique characteristics of the display panel. This is not a malfunction of the product. •• The screen's brightness seems dark. -- Adjust brightness and contrast again. -- Backlight may need repair. Issues Related to Sound •• The audio doesn't work. -- See if the audio cable is connected properly. -- Adjust the volume of the product or external device. -- See if the sound is set properly. •• Sound is too dull. -- Select the appropriate equalizer sound. •• Sound is too low. -- Adjust the volume of the product or external device. •• For some models, you will need to purchase external speakers separately since they do not have speakers built-in. Other Issues •• The power suddenly turned off. -- Check if the 'Power Off Time' is set. -- Power interrupted. See if the product power cord is connected properly. -- Check the power control settings.
