LG Monitor Not Connecting To Laptop/Mac/PC

Black modern monitor on the table

We all expect life to be good when we purchase a new LG monitor. Unfortunately, there are also problems that sometimes occur.

A common reason why your LG monitor is not connecting to the computer is that the cables are not connected properly. In order for everything to work, the cables need to be new, in good condition, and well seated in the port.

You may be somewhat limited in the type of cables that you use, depending upon the computer that you are using. Most PCs will have plenty of port options but if you are using a laptop or a Mac, you may be limited to HDMI.

An HDMI cable will still work fine for your LG monitor, but new technology requires that you are using new cables. Older HDMI cables may not carry enough signal for your LG monitor. It might work, but it may not work as expected.

If you need to use a VGA but you don’t have a VGA port on your computer, you can purchase a converter. These are relatively inexpensive and make it easy for you to use HDMI or USB 3 to connect to a VGA port on the LG monitor.

If you have problems with your LG monitor and you contact customer support, the first thing they are going to tell you to do is to reset the monitor. They may also tell you to unplug the monitor and cables.

This is actually something that works in many cases. Sometimes, the computer just doesn’t recognize the monitor when it first sees it. It may take a reset or a soft restart to get things working.

We will discuss a soft restart throughout this article, but here are the general steps used for it:

1. Turn off Power

Turn off the LG monitor and disconnect the power cable. If you can’t reach the receptacle, you can turn off the circuit breaker.

2. Shutdown Computer

Make sure that you are doing a full shutdown of the computer and not simply putting it to sleep.

3. Disconnect Cables

Remove the cable between your computer and the LG monitor.

4. Wait

After turning off the computer and monitor and disconnecting the cable, wait at least five minutes before doing anything else.

5. Press and Hold

The purpose of waiting is to allow any energy in the LG monitor to fully dissipate. You may, at this point, press and hold the power button on the monitor for 30 seconds. Doing so ensures that all of the power has been removed.

6. Connect Cables

Reconnect the cable between the LG monitor and your computer. Make sure that you are using a new, high-quality cable and that it is fully seated in the ports.

7. Turn on Computer

press the power button on the computer and allow it to fully restart.

8. Turn on Monitor

Plug in the LG monitor and press the power button. Your computer should recognize the monitor and begin the brief setup process.

Let’s consider some factors that are specific to the type of computer that is being used when problems occur.

The order of operations really matters when it comes to connecting your MacBook with a new LG monitor. If it isn’t connecting properly, turn off your MacBook and then connect the display while the MacBook is in the off state. After waking up or restarting your Mac, it should recognize the monitor and begin working.

One other thing to check is that the cables are fully inserted into the ports. If the cables are loose, old, or damaged, they will not work as expected.
