Fix 3: Check Power & Video Source
Change the power source of your monitor to see if the issue is resolved. If none of the outlets in your home are able to turn your monitor on, then there might be a blown fuse or a broken connection.
Should the monitor turn when plugged into a different outlet, the issue might be with the initial power source. This simple step may help you save time by identifying the precise location of the issue.
Also, make sure to select the correct Video input for the monitor to display something. Follow the steps below:
- Press the Joystick button on your monitor.
- Move the joystick to the right and select Settings.
- Select Input from the sidebar.
- Now, select any of the HDMI inputs, DisplayPort, or USB-C. Make sure you select the input that is connected to your device.
Fix 4: Check your Cables
Check the integrity of your power and HDMI cables to make sure everything is running fine. Check for any visible signs of damage, such as tattered or twisted wires, on the HDMI and power cables.
Additionally, check the integrity of the connections. Securely insert the HDMI cable into the source device (game console, computer, etc.) that you want to connect to the monitor.
You should also inspect the power line to ensure that the monitor is snugly connected to the outlet. Power surges resulting from a loose connection have the potential to damage the display.
If any of the cables are frayed or damaged, you should replace them immediately. Make sure to buy good quality cables that are compatible with your monitor.
Fix 5: Graphics Card Connection
Many users make the mistake of connecting their DisplayPort to the motherboard instead of the Graphics Card. If you are one of them, remove it from the motherboard and connect it to the Graphics Card of your PC. Make sure to insert it into the correct port on your Graphics Card.
Fix 6: Test with Another Device
Just plug it into another device, like a computer or gaming console, and see if the issue still persists. With the help of this, you can narrow down the likely cause to the device that originally connected it. If the monitor turns on when connected to a different device, then the issue lies with the current device and not the monitor.
If that’s the case for you, check out Fix 8, Fix 10, Fix 11, and Fix 12. These fixes tackle the device-related issues that could be preventing the monitor from turning on or displaying something.
Fix 7: Reset the Power Strip or Surge Protector
Resetting a surge protector or power strip is a must before using it. There is a possibility that these parts might trip or fail, cutting power to the monitor. Resetting these safety features may fix their issue. To reset your surge protector or power strip, follow the steps below:
- Power off all the devices connected to the surge protector or power strip.
- Find the reset button on your surge protector. The button is usually tiny and hard to find.
- Press the button, and the surge protector will be reset. If you can’t find the reset button, simply disconnect your monitor from the surge protector and reconnect it.
- You can even plug the monitor directly into the power outlet if you want to.
Fix 8: Remove and Re-insert the RAM Strips
RAM failure can be the reason why your LG Ultragear gaming monitor might not turn on or display anything. If the RAM isn’t working properly, this will lead to a system failure, causing the monitor to go blank.
One way to fix a RAM failure on your PC is by removing and re-inserting the RAM strips. This resets the connection with the motherboard and the other components of your PC. Make sure to be gentle with the RAM strips during the process. You can also run a CheckDisk scan to ensure the integrity of the RAM:
- Press the Windows key + Q on your keyboard and type “cmd” in the search bar.
- Now, click on Run as administrator.
- On the UAC prompt, click on Yes.
- Type the following command and press Enter:
chkdsk /f /r
Once the command is executed, restart your Windows PC by going to Start > Power icon > Restart. Check to see if the issue has been resolved.
Fix 9: Factory Reset
If the issue persists, you can try to factory reset your monitor and see if that helps resolve the issue. Restoring the screen to its factory settings should fix the issue if the issue is related to the software. Follow the steps below to factory reset your LG Ultragear gaming monitor:
- Press the Joystick button on your monitor.
- Move the joystick to the right and select Settings.
- Select General and then Reset.
- Select Yes.
- Your monitor will now restart.
Fix 10: Update Windows/macOS
It is important to keep your operating system up-to-date at all times. Perhaps, patches and fixes included in updates will address issues with the compatibility or performance of your monitor. The latest system update should fix any issues you’re experiencing with your monitor. Follow the steps below:
Windows:
- Press the Windows key + I on your keyboard to open the Settings app.
- Now, select Windows Update from the sidebar.

- Restart your Mac once the update is installed.
Fix 11: Update Graphics Drivers (Windows Only)
You should also keep your Windows graphics drivers up-to-date at all times. Problems with the graphics could arise if the drivers are either outdated or incompatible. Staying up-to-date with your graphics driver updates should help your computer and monitor work together better. This may resolve the problem. Follow the steps below:
- Press the Windows key + X simultaneously and select Device Manager.
- Once the Device Manager window opens, click on the arrow next to Audio inputs and outputs to expand it.
- Right-click on the audio drivers and click on Update driver.
- Then, click on Search automatically for drivers.
- Once the drivers are installed, restart your PC and see if the issue has been resolved.
If the issue persists, you can also reinstall the audio drivers on your PC. This will delete the existing drivers that might be corrupted and install fresh ones automatically. Here’s how:
- Press the Windows key + X simultaneously and select Device Manager.
- Once the Device Manager window opens, click on the arrow next to Audio inputs and outputs to expand it.
- Right-click on the audio drivers and click on Uninstall device.
- Do this for all the audio drivers available.
- Restart your PC, and the missing drivers will be installed automatically.
Fix 12: Update BIOS (Windows Only)
If the issue still persists, there might be an issue with your BIOS settings. If your BIOS settings are corrupted or if the BIOS itself is outdated, then you might not be able to display anything on any monitor, let alone your LG Ultragear gaming monitor. Follow the steps below to update your BIOS:
Note: Take a backup of all your data before proceeding. Although BIOS updates don’t lead to data loss, it is better to be cautious.
- Press the Windows key + X simultaneously and select Device Manager.
- Once the Device Manager window opens, click on the arrow next to Firmware to expand it.
- Right-click on “-System Firmware” and click on Update driver.
- Then, click on Search automatically for drivers.
- Once the drivers are installed, restart your PC, and your BIOS will be updated.
Fix 13: Check for Physical Damage
Check for the usual signs of screen wear and tear, such as dents, fractures, or exposed wires inside the cables. The internal components of the monitor are susceptible to physical damage, which could render it worthless.
If the monitor is physically damaged, then it will obviously not turn on. In this case, you can either get it repaired or buy a new monitor altogether. You can better decide what to do.
If the problems persist after you have tried the aforementioned options, please contact the manufacturer’s support team. You can contact the LG support team via their website or request for a repair. Even if there is no physical damage to your monitor, you should send it for repair for a quick resolution.
