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.
LG Monitor Not Connecting To Laptop/Mac/PC
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.
After turning off the computer and monitor and disconnecting the cable, wait at least five minutes before doing anything else.

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.

Your LG monitor and laptop should work well together. It’s a convenience that many people appreciate. Here’s how to set things up properly.
Modern LG monitors are plug-and-play compliant. In other words, when you plug an LG monitor into a laptop, it should walk through the setup process without any interaction on your part. Setting up a single LG monitor on a laptop should be a simple matter of plugging it in and pressing the power button.
There are also some power users who want to have multiple LG monitors plugged into their laptop. If that is the case, you may need to use the input button on the monitors to switch the input from one to another.

LG Monitor Not Connecting To MacBook/MacBook Pro/MacBook Air
We really love our MacBooks because they work so well with any peripherals that we connect to them. This is also true of LG monitors, but what can you do when they are not connecting properly?
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.

2. Turn on Mac
The MacBook should be turned on after the monitor is on and fully started. It may recognize it, even if you plug it in first while the Mac is on but connecting while it is asleep or off ensures that it is recognized.
3. Press a Button
It may be necessary for you to press a button on the keyboard so the monitor wakes up and is recognized as an external display.

You may need to reset the monitor and cycle the power on the PC to get things to work properly. It isn’t always necessary, but unfortunately, PCs are imperfect and at times, they may need a little help to recognize the LG monitor.
If all else fails, press the Windows logo key + P to enter the presentation display mode.
How To Connect LG Monitor To PC
Connecting an LG monitor to your PC is going to be one of the easiest things you have ever done with your computer.
LG monitors are plug-and-play compliant so when you connect them to a PC, they will be recognized automatically and the setup will take place without any work on your part. This is true of the first monitor as well as a second monitor.
If multiple monitors are being used, you can select the input button on the controls of the monitor to ensure that it is recognized.
An initial step of configuring the monitors in the setup of your operating system may also be necessary. This will ensure that the monitors are recognized and displayed properly.
When your LG monitor is not connecting to your computer, check the cables. They should be new cables that are free of damage and should be inserted fully in the ports on both the computer and the monitor. You may need to restart both the computer and monitor if you are experiencing problems or have to change the cable.
