Through this guide, we want to assist you and help you figure out the solution yourself without having to spend money on a technician. Let’s get started!

  1. Check all the connecting wires and see if any of them is loose. The video cable should particularly be secure. If you use LCD TV in Video mode, check that as well. Sometimes, you may connect the cable in the wrong input, causing this problem. So, make sure you didn’t commit that error. Also, we recommend that you change the video cable and see if the problem persists. This will tell you if the cable is at fault. If yes, simply changing it will solve your problem and you won’t need to bother with the rest of the tips!
  2. While you are at it, you may also want to use the original cable with another monitor and see if the problem repeats. For all we know, the monitor’s display is at fault, and your cable is completely fine.
  3. Look around and see if any other electronic devices are causing interference. This is a big factor sometimes, and we don’t realize it. Other monitors, electric clocks, radios, fans, and TVs are the culprits in this case. Try removing devices that are in close proximity to your LCD monitor and see if that makes a difference.
  4. Your video card has to be compatible with the resolution of the display. Take a quick look to be sure because compatibility issues have also been known to cause horizontal lines on the monitor screen.
  5. Go to your Control Panel and into Advanced Settings to check the refresh rate. Change it and see if that helps because as we discussed earlier, the refresh rate is likely the reason behind your problem.

If none of these works, we recommend that you talk to a technician because the problem may be too advanced. Don’t try doing things like opening up your monitor unless you are sure about what you are doing. All the best!
