Why Is My LG TV So Slow? (8 Quick Fixes)

Most LG TV users have to face the sluggish performance of their smart TV. And it’s one of the worst experiences: the apps open late and start lagging, stuck screens hinder streaming, and the TV responds slower to your commands.

The primary reasons that slow down the LG TV’s performance are the unnecessary apps, slow internet connection, outdated firmware, and cache. 

Luckily, you can fix this problem in a few minutes.

So let’s jump into it. 

How To Fix The Slow Performance Of LG TV?

1- Power Reset

Before going for any other solution, try power resetting your LG TV. In most cases, this simple solution can fix the slow performance of LG Smart TVs. 

No matter your LG TV model, the power reset method is the same for all. It will fix all the connectivity, performance, cache, and software-related issues and glitches. 

Here is hot to power reset LG TV;

  • First, unplug the TV from the power outlet or wall mount. 
  • Wait for at least 30 seconds. 
  • Now press and hold the power button of the LG TV for 10 to 15 seconds. 
  • Plug back the TV power cable into the outlet.
You should try this method 2 to 3 times; if the first attempt fails, the second or third will work.

Surely, this simple chore will fix the slow performance of the LG TV, and if it fails, move on to the next solution.

2- Fix The Slow Internet Connection

Fix The Slow Internet Connection

The performance of LG TVs depends on the Internet connection. The faster the internet connection, the quicker the apps open, and the smoother the streaming experience. 

One of my smart TVs also got sluggish due to the internet connection, and I simply reset the router, and it started working fine.

You need to first conduct an internet speed test; for that purpose, you can use any speed testing website like Fast.com or Speedtest.net. If you have encountered sluggish internet speed, then it’s time to restart the router. 

Below are the steps to restart the router; 

  • Unplug the router from the main power source. 
  • Wait 10 – 15 seconds to allow the router to fully power down. 
  • Now plug the power cable of the router back into the outlet.

You might be wondering what happens when the router restarts. This process clears all the cache and temporarily stored data from the router and eliminates all the potential connectivity glitches. 

So if your Internet connection is slow or you’re facing connectivity issues, restarting the router will fix these problems. 

3- Use Ethernet Or Wired Connection 

Use Ethernet

Most of the time, the router is far from the smart TV, so the TV doesn’t catch the strong wifi signals resulting in a slow internet connection. And if the internet connection is slow, your LG TV automatically slows down. 

If the wifi router is at a distant location from your LG TV, you should use the ethernet cable to eliminate the latency rate. Ethernet cable doesn’t depend on the distance; that’s why it provides a smoother internet connection. 

The wifi signals interrupt the medium between the router and the source. 

Due to the mediums like roofs, fans, and walls, the wifi signals get weaker, and your smart TV doesn’t catch sufficient signals if the router is placed far away from it. 

To establish an Ethernet connection, you only need an Ethernet cable. Connect one cable end with a router and the other with your LG TV (into the ethernet port). And that’s it! You don’t need to do anything else.

4- Update The Firmware

LG TVs run on WebOS, and the company launches frequent updates to eliminate glitches and bugs. The outdated firmware is also a primary reason that impacts the LG TV performance and makes it slower. 

If you have missed several firmware updates on LG TV, the TV will be more prone to bugs and glitches that make it sluggish. 

Lagging and slow opening of apps on LG TV is also caused by outdated firmware. 

Most of the time, the LG TV updates the firmware automatically if it is connected with a stable internet connection, but sometimes updates get missed due to internet issues. In this case, you need to manually update the firmware. 

Below are the steps to manually update the firmware of LG TV. 

  • Go to “Advanced Settings.”
  • Scroll down to “General.”
  • Under General settings, tap on “About This TV.”
  • Now tap on “Check For Updates.”
  • If any new update is available, the TV will automatically download the update.

Note: Before processing updates on LG TV, ensure it’s connected with a stable internet connection. 

5- Go For 5GHz Band Network 

If your home’s internet speed is slow, you’re using a 2.4GHz band network

You need to replace the 2.4GHz band adapter with the 5GHz to improve the internet speed and get a stable connection. The 5 GHz band has a wider channel width and can transmit more data simultaneously.

So if you want to eliminate the lagging of streaming services on LG TV or improve the TV performance, you should use the 5GHz band. 

Especially if you’re living in a small apartment or a room, 5GHz is the best option because it works well in proximity. At the same time, the 2.4GHz band is best for distant connections. 

6- Ask Your Internet Service Provider To Increase The Internet Speed

If you connect multiple devices with the same wifi network, the internet connection will gradually become slow. Similarly, your LG TV will also catch weak wifi signals

In this scenario, you must contact the internet provider and ask them to upstage the current internet plan. 

You should use 30 Mbps or higher internet speed for streaming apps and high-level internet usage. Once you have upgraded the internet speed, you will never face lagging issues on your LG smart tv. 

7- Fully Closed Apps To Improve The Memory Health

There is limited memory on LG TV, and the more apps you have on the TV, the more will increase the memory consumption, slowing down the LG TV performance. 

It’s mandatory to fully close the apps on LG TV to avoid them from running in the background. If you just press the back button to close the apps, you’re increasing the load on memory. 

The LG TVs give the easy option to fully quit an app, and you should use that option instead of just pressing the back button.

Here are the steps to fully close the apps on LG TV: 

  • Open the app that you want to be fully quiet. 
  • Press the three-dot button from LG TV remote control. 
  • A menu will pop up on the right side. 
  • Now tap on the “Quit App” option to fully close the app.

8- Factory Reset LG TV

Here are the steps to factory reset your LG TV. 

  • Go to “Advanced Settings.” 
  • Scroll down to “General.” 
  • Tap on “Reset To Initial Settings” 
  • Now press ok to confirm

The process will take a few seconds, and the LG TV will automatically restart
