Monitors that aren’t working are usually the result of a bad video card or a bad graphics driver. However, monitors might fail for a variety of reasons. If your LG monitor isn’t working or isn’t working properly, try following this instructions to figure out why and how to solve the problem.
LG Monitor Doesn’t Turn On
If your LG monitor won’t turn on, double-check that it’s turned on and that the power and display cables are connected properly. If the problem persists, check that the monitor is set to the correct input and that the display resolution is reduced. Perform a factory reset as a last resort.
Other reasons for your LG monitor not turning on include PC difficulties. To begin, test the monitor with another device to ensure that the problem is not caused by the computer. Then, update the graphics driver and BIOS, and double-check that the display cable is correctly connected to the graphics card. Replace the RAM sticks and reset the CMOS/BIOS.

- Confirm monitor is ‘actually’ ON
- Check power cable connection
- Check display cable connection
- Set monitor to correct Input
- Lower display resolution
- Factory reset monitor
- Test monitor with another device
- Update graphics driver and BIOS
- Ensure display cable is plugged into graphic card
- Reinsert RAM sticks
- Reset CMOS/BIOS
Troubleshooting An LG Monitor That Won’t Turn On
Step 1: Verify that the monitor is ‘really’ turned on.
When you go to turn on your computer, all you get is a blank screen. Your LG monitor will not power up. Now what?
First, check sure your monitor is turned on before moving on to more complicated remedies.
Yes, I understand. This seems self-evident. This is a common mistake because you usually only turn your monitor on once and rarely need to do it again.
Your monitor frame’s ON button will be on the front, bottom, or side panel. It is usually found on the right side. Turn on the monitor.
Step 2: Double-check the power cable.
Next, double-check that both ends of the power cord are securely attached.
The power cord may not be securely placed into the power socket, resulting in your LG monitor not turning on.
Check the power outlet on the wall and the connection on the back of your monitor. Make sure you check your power cord for any visible damage.
Step 3: Make sure the display cable is connected.
Ok. You’ve double-checked that the power is on and that the power cable is secure. However, your LG computer monitor remains unresponsive. Let’s stay with the cable theme for now.
You should also double-check that your display wire is securely connected.
HDMI, DisplayPort (DP), VGA, and DVI are all common display cables. Even if the connection is minimally damaged on either end, an error can occur.
Do you see the tiny space between the HDMI and the HDMI port in my laptop in the image below? That was enough to result in a black monitor screen, as you might expect.
Disconnect and reattach the cable a few times. To avoid future problems with a VGA or DVI cable, tighten the screws all the way.
Step 4: Select the proper input on the monitor.
Let’s also double-check that your display is configured to the proper input.
To do so, you must first determine the type of input cable you are using.
HDMI, DisplayPort (DP), DVI, and VGA are the most common display cables, as previously stated. Use the image below to figure out which cord you have.
Display cables include HDMI, DisplayPort, VGA, and DVI.
Locate the Input button on your monitor once you’ve found the suitable display cable. Your monitor frame’s input button might be placed on the front, bottom, or side panel.
Identify the input that matches your display cable by adjusting the input settings.
Step 5: Reduce the screen resolution
LG monitors support a wide range of display resolutions that can be transmitted to your computer.
It’s conceivable that your computer’s graphic card is now configured to a higher display resolution than your LG monitor supports.
If this is the case, it is possible that your LG monitor will not switch on.
To resolve this, we must first restart your computer in Safe Mode.
Your computer will automatically use a lower display resolution than normal when in Safe Mode. This will enable you to access your computer’s resolution settings and choose a lower conventional display resolution.
Do you know what resolution your LG monitor can handle? You can choose between two options:
Look up the maximum resolution in the LG user manual by looking up your LG model number on the back of your monitor.
Make use of some good ol’ trial-and-error. Increase your resolution gradually. Wait around 30 seconds between each update to see if the monitor is still on.
Step 6: Reset Monitor to Factory Settings
When your LG monitor won’t come on, resetting it to factory settings may be enough to get it back up and running.
To factory reset your monitor, look on the back of the display for the LG model.
Then, using the LG user manual lookup, input your LG monitor model number and follow the manual reset instructions.

Step 7: Use a different device to test the monitor.
If your monitor is the root of the problem, we’ve reached the end of the most typical remedies.
To make sure your display is the problem, try using it with another device. This could be a different computer, laptop, game console, or other device.
If your monitor’s display works, your monitor is in good working order and your hardware is to blame.
Troubleshooting The PC – LG Monitor Not Turning On
You’ve established that your display is compatible with another device. What now? It’s possible that the problem is with your computer.
First, a couple of caveats. You must open and manage your laptop or desktop computer in steps 10 and 11.
If your gear belongs to your firm, you should delegate these tasks to your IT department.
Even if your gear is your own, you may want to take it to a local computer repair business.
If you do decide to go forward, be sure you’ve done your homework. To stop electrostatic charge from harming your computer, you should know how to properly ground yourself.
Step 8: Install the latest graphics drivers and BIOS.
Your graphics driver and/or operating BIOS version may be obsolete if your hardware is the issue.
Follow the links below to ensure you have the most recent graphics driver and BIOS updates.
How can I check for updates if my LG monitor won’t turn on?
If you’re using a docked laptop, there’s no need to be concerned. If you’re using a desktop computer, though, you’ll need to borrow a monitor to make the change.

Step 9: Ensure Display Cable Is Plugged Into The Graphic Card And Not The Motherboard
Double-check that the display cable is connected to the graphics card rather than the motherboard.
Almost every desktop computer has an on-board graphics unit with appropriate ports on the back.
If this is the case, make sure your display wire is linked to the graphic card rather than the motherboard.
For this reason, your LG monitor may not come on when connected to a desktop PC.
Step 10: Remove, Reorder, And Reinsert Your RAM Sticks
It’s possible that your LG display isn’t turning on because your RAM (Random Access Memory) sticks aren’t connected properly.
The failure to transmit electricity to your mouse and keyboard is one way this problem can emerge.
If your mouse and keyboard aren’t working, it’s most likely due to a bad RAM stick connection.
To resolve this, make sure your computer is turned off and the power cord is disconnected from the socket.
After that, ground yourself properly and open your PC unit. Then completely remove each RAM stick.
Finally, rearrange the sicks and re-insert them into their RAM seats.
Replace RAM sticks if your LG monitor won’t turn on.
Step 11: Reset the CMOS/BIOS settings
Complementary Metal Oxide Semiconductor stands for Complementary Metal Oxide Semiconductor.
The BIOS firmware is powered by the CMOS battery in your laptop or computer. BIOS stands for “Basic Input/Output System,” and it controls your computer’s key functions.
Resetting your BIOS returns it to its default settings. This can often solve a variety of problems, and it’s something you should attempt if your LG monitor won’t switch on.
Make sure your computer is turned off, the power cord is disconnected, and you are properly grounded once more.
Remove the CMOS battery from the motherboard after that.
Hold the power button down to drain any leftover power.
Replace the CMOS battery in your PC after roughly a minute.
Finally, restart your computer and verify that your display is operational.
