Troubleshooting
| Problem | Possible solutions |
| THERE IS NO LED DISPLAY or SCREEN SAYS NO SIGNAL | Make sure you switched to the correct source. Check both sources to see if the video is on the other source. Check your video cable. It might be corrupt. Swap out the video cable for another one to see if the monitor will work. Check your power plug. See if it is fully plugged in on both the monitor and the wall. |
| MONITOR SAYS “SIGNAL OUT OF RANGE” | If you have a CRT monitor, please connect the CRT monitor to the computer and change the refresh rate down to 60 Hz via your video card’s display settings menu. After the setting of 60 Hz has been changed, you can then use the C34 LED Monitor on the computer. 1. To change the setting, go to display settings by right-clicking on your desktop with nothing selected. Choose the PROPERTIES option. 2. Click on the SETTINGS tab, verify the resolution is NOT higher than 3440 x 1440, and click on the ADVANCED button. 3. Click on the MONITOR tab and change the refresh rate to 60 Hz. 4. Click on OK 2-3 times to finalize your change. If you do NOT have a CRT monitor or it is already broken, please make sure both the C34 LED monitor and your computer is turned off. 1. Turn on the LED monitor and the computer. 2. While the computer is turned on, press the “F8” key on your keyboard continuously until a selection menu appears and select the “Safe Mode” option. 3. When you have entered Safe Mode, please uninstall any video card driver and monitor driver by using either the “Add / Remove Programs” icon or going into “System.” 4. Properties” and manually removing anything under “Monitors” and “Display Adapters”. After removing all the drivers, please reboot your computer and you should be able to see Windows. Please install your monitor driver first, then your video card driver. Please remember to make sure your refresh rate should be at 60Hz. |
| I CAN’T OPEN THE OSD | You need to have a valid video signal going through the monitor before you can turn on the OSD. |
| Problem | Possible solutions |
| I CANNOT GET THE RESOLUTION | Sometimes your video card will not read the monitor correctly and will not allow you to achieve the resolution you want. Rebooting your computer will solve the situation.
You can also make sure your video card’s video drivers are up to date. You can find what video card you have by clicking on START then RUN. Type in “DXDIAG”. When the diagnostic window pops up, click on the DISPLAY tab. The program will tell you what video chipset you have. Copy that name then search it with an online search engine like GOOGLE™. Find your video card company’s web address and search for newer drivers. If updating your drivers does not work, you probably have one of the older video cards and cannot achieve a widescreen resolution. You will need to upgrade your video card to a newer one. |
| THE VIDEO IS TOO BRIGHT NO MATTER WHAT I ADJUST | Sometimes having older video cards, this type of problem might happen due to newer LEDs having to provide HD video capability and not being fully compatible with older video cards. You can try adjusting the contrast to a lower value and adjust the brightness to compensate. |
| THE WORDS AND VIDEO ARE TOO BLURRY | Are you using the monitor’s native resolution? If not, you will need to switch resolution to the native 3440 x 1440 at 60 Hz to make the words clearer.
If the words are still blurry, please try enabling or disabling the CLEAR TYPE function from Windows. |
| THE COLORS ARE NOT CORRECT | Sometimes the colors are not correct because your DVI or DP or HDMI cable is loose or corrupt. Please try reconnecting your cable or swap out your current cable to see if the problem persists. |
| HOW DO I RESET THE MONITOR | Make sure there is a valid video signal to the monitor and press menu to open the OSD. Look for RESET under the OTHER options. |
| I CHANGED MY COLOR SETTINGS NOW I CAN’T GET THE FACTORY DEFAULT BACK. | Open the OSD, under OTHER, select RESET to reset all values back to factory default. |
