Troubleshooting and error codes
| Issue | Resolution |
|---|---|
| Screen issue: The brightness and color do not look normal. |
Go to Settings → Picture and adjust the screen settings such as Color, Brightness and Sharpness. Go to Settings → System and adjust the Power and Energy Saving settings. Reset the screen settings to the default settings. (P.86) Check the cable connections. |
| I see red, green, and blue. | This issue may happen when the panel of the product is defective. Contact a Samsung Service Center to resolve the issue. |
| The display looks unstable and then freezes. | The screen may freeze when a resolution other than the recommended resolution is used or if the signal is not stable. To resolve the issue, change the PC resolution to the recommended resolution. |
| The screen cannot be displayed in full screen. |
A scaled SD (4:3) content file can cause black bars on both sides of an HD channel screen. A video with an aspect ratio different from the product can cause a black bar to appear at the top and bottom of the screen. Change the screen size setting to full screen on the product or source device. |
| Sound issue (For models with built-in speakers): There is no sound. | Check the connection of the audio cable or adjust the volume. |
| The volume is too low. |
Check the volume. Adjust the volume. If the volume is still low after turning it up to the maximum level, adjust the volume on your PC sound card or software. |
| Sound issue (For models with built-in speakers): Video is available but there is no sound. |
If an HDMI cable or a DP cable is connected, check the audio output settings on the PC. Go to Settings → Sound and change Sound Output to Internal. If a source device is used: Make sure the audio cable is properly connected to the audio input port on the product. Check the audio output settings for the source device. (For example, if your monitor is connected to HDMI, you may need to change the audio option of your video output device to HDMI.) If the product has a headphone port, make sure nothing is connected to it. Reconnect the power cord to the device and then restart the device. |
| There is static coming from the speakers. |
Check the cable connection. Make sure a video cable is not connected to an audio input port. Check the signal strength after connecting a cable. Low signal level can cause corrupted sound. |
| Remote control issue: The remote control does not work. |
Make sure that the batteries are correctly in place (+/-). Check if the batteries are flat. Check for power failure. Make sure that the power cord is connected. Check for any special lighting or neon signs switched on in the vicinity. |
| Source device issue: A beeping sound is heard when my PC is booting. | If a beeping sound is heard when your PC is booting, have your PC serviced. |
| Other issue: The product smells like plastic. | The plastic smell is normal and disappears over time. |
| The monitor appears tilted. | Remove and then attach the stand again to the product. |
| Audio or video cuts out intermittently. |
Check the cable connection and connect it again if required. Use a standard cable. |
| Small particles are found on the edges of the product. | The particles are part of the product design. The product is not defective. |
| When I try to change the PC resolution, a message "The defined resolution is not currently supported." appears. |
The message "The defined resolution is not currently supported." appears if the input source resolution exceeds the maximum resolution of the display. To resolve the issue, change the PC resolution to a resolution supported on the display. |
| There is no sound from the speakers in HDMI mode when a DVI-HDMI cable is connected. |
DVI cables do not transmit sound data. Make sure to connect the audio cable to the correct input port to enable audio. |
| HDMI Black Level is not functioning properly on an external device with HDMI YCbCr output. | This function is available only when a source device with RGB signal, such as a DVD player and STB, is connected to the product to HDMI cable. |
| Other issue: There is no sound in HDMI mode. |
Displayed picture colors may not look normal. Video or sound may not be available. This can occur if a source device that only supports an older version of the HDMI standard is connected to the product. If these issues occur, connect an audio cable along with the HDMI cable. Some PC graphics cards may not automatically recognize HDMI signals that do not include sound. In this case, manually select a sound input. |
| HDMI-CEC does not work. |
To use several external devices compatible with the HDMI-CEC feature that are connected to the HDMI ports on the product, turn off the HDMI-CEC features on all the external devices. External devices include Blu-ray and DVD players. Operating an external device when its HDMI-CEC feature is enabled may automatically stop other external devices. To change HDMI-CEC settings, refer to the device user guide or contact the device manufacturer for assistance. |
| In power-saving mode, when the input source is DisplayPort, PC display settings cannot be saved. | Go to Settings → System → Power Control and set Max. Power Saving to Off. Alternatively, configure the PC display output settings again. Ensure the product is turned on. |
| When booting the PC with the input source set to DisplayPort, the BIOS and booting screens do not appear. | Boot the PC when the product is turned on or when the input source is not DisplayPort. |
