LG Monitor Not Working
Monitors not working are generally a sign of a defective video card or an improper graphics driver. However, sometimes, monitors fail for other reasons. If your LG monitor isn’t functioning or is improperly functioning, try to follow this guide to understand why and fix the issues.
Test if the Monitor is Properly Powered
To help diagnose where the problem is, you should test to make sure that your monitor itself is not the problem. LG Monitors use energy-saving technology, so if there’s no signal, they may appear to be off – but there should be an indicator light somewhere on the model. Check to see if it’s powered.
- Do you have a power strip that the monitor is plugged in to?
- Is power supplied to the other devices plugged into the strip?
- Is there a standby light when the monitor is plugged in? Does toggling the power make anything happen?
- Do you have any other devices you can plug in? Does the monitor work when they are plugged in instead?
If the power is working to everything else, but the monitor still isn’t working, it could be the power cable for your LG monitor. See if replacing the LG Power Cable fixes the issue. You can call or contact LG to get a replacement power cable.
Test if your Video Cables Work
If your monitor seems to be receiving power, but no signal is provided when plugged in, you could have a frayed video cable.
- Try using the cable you have hooked up with another device. Does that one also perform similarly? Are you getting an error on your LG monitor?
- Try replacing the cable that you’re using. Most monitors use either VGA, DVI, Display Port, or HDMI to connect to a computer. Determine which one you use with your computer and see if you have a replacement somewhere in the house. If you don’t, you can usually buy them for pretty cheap online or at major retailers.
If replacing a cable fixes the issue, discard the old cable and use the new one.
Test Another Display
This may be more difficult, but if your desktop or laptop has an HDMI port, try plugging it into a TV. Do you get a response from the TV when you’re on the correct channel? If so, your monitor may be broken or faulty. You should reach out to your retailer if your monitor is still under warranty, or reach out to LG to try to receive a replacement.
Graphics Card Problem
If your graphic card has multiple output ports on it, try a different port for your cable to see if the issue is the port. Sometimes, whether you’re on AMD or Nvidia, one of your outputs will fail. If this clears the problem, contact your retailer or manufacturer to try to get a refurbished card.
Sometimes, a faulty or out-of-date driver can cause graphics issues as well. If you’re on a desktop and you have an integrated graphics output, try plugging into that output and updating your video card’s drivers. If you’re on a laptop, try using your native screen and updating your graphics drivers as well as your chipset drivers.

Have you tried multiple cables? Could it be a bad cable? If multiple cables don’t work and it works with a different monitor, maybe the monitor is broken. Has it worked on other devices? Such as a phone, or a DVD player?

My H/P does not have HDMI ports, so I used the VGA. I get the message “not connected” on the LG monitor. BUT, when I hooked up my OLD monitor to the same cable, it all works fine.
