LG TV Lagging (This Worked!)

| Published:

When you find your LG TV lagging, it can affect your ability to enjoy content.

Today we will look at what caused LG TV lagging and the steps you can take to prevent it from happening!

Why Does LG TV Keep Lagging?

Most times, your LG smart TV may experience lagging when you try to load apps. 

This is due to your memory cache being full. Like your personal computer, your LG TV has a cache that stores data, and it can become full and lead to a sluggish performance.

With time the cache can become whole and cause your LG TV to lag.

Your TV can also lag when playing content due to streaming issues on your LG TV.

How to Fix LG TV Lagging

If this is your first time experiencing such issues, restarting your LG TV can stop the problem.

But for a recurring problem. Please read through the steps to know how to troubleshoot his problem.

Method 1. Check your internet connection

An unstable internet connection is one of the most common reasons why you are experiencing lagging on your LG Smart TV.

Ensure you check if the network does not have a problem. Do this, and you might get your smart TV up and running.

How to check internet speed on LG TV?

The easiest way to check your LG TV’s internet speed is to head to speedtest.net on your TV’s web browser.

We will review other options for testing the internet speed on your LG TV.

Use your LG TV web browser

One of the easiest ways to test the internet speed on your LG TV is by using your web browser.

Step 1: Choose the web browser from the menu bar from your LG TV.

Step 2: In the URL bar, type speedtest.net

Step 3: Hit go

Method 2. Restart your LG TV

If, after you have checked the internet connection and the issue is persisting.

Try restarting your TV.

Switch it off and plug it in from the power source for at least 30 seconds. Then, plug it back in and turn it on again.

This can help resolve your lagging problem.

Method 3: Reset your Router

Resetting your router can be an effective trick to preventing your LG TV from lagging.

How do I reset my router?

The easiest way to reset your router is to unplug it from the wall socket for 30 seconds before plugging it back in.

This action will “power-cycle” your router and provide more bandwidth to your LG TV, which can prevent stuttering.

Think of all the devices that are and have been connected to the router. I’m sure that in today’s digital world, quite a few devices are connected to the router.

Your router is like a mini-PC and will slow down as more tasks are added.

Having all those devices connected will reduce the bandwidth available to your LG TV and subsequently throttle your download speed, creating lagging.

Method 4: Close any apps that are running

If you followed the step of restarting your LG TV, then this step would have been completed for you, otherwise, please continue to close any running apps.

How does having open apps cause your LG TV to lag?

The more apps you have open on your LG TV, reduces your TV’s performance and the internet connection.

This performance degradation can cause your LG TV to lag when streaming content.

Method 5. Clear Cache 

You should consider clearing your LG TV cache when you have lagging.

There are currently two ways to clear your cache.

Newer LG TV Models

Method 1: Restart your LG TV

LG now automatically clears your cache when you restart your TV.

You can restart your TV by long pressing the power button on the remote.

Method 2: Use the LG Memory Optimizer

You can access a “Memory Optimizer” function on newer LG TVs.

The memory optimizer function will optimize your TV status by deleting unused apps and clearing some of your TV RAM/caches.

You can access the memory optimizer tool by following the instructions below.

  • Settings Button (Remote)
  • OLED Care
  • Device Self Care
  • Memory Optimizer

This option will also clear non-primary apps that are running in the background.

Older LG TV models

If your TV is an older LG, you must navigate the menu system and manually delete the cache.

1. Navigate to the Settings menu on the LG TV

2. Locate the Storage or Memory option

3. Select the Clear Cache option

4. Confirm the action and all

Method 6: Update your LG TV firmware

We have found that older unsupported LG TV firmware cause lagging when streaming content on your LG TV.

I recommend updating your LG TV firmware to ensure you have the latest software, access to new apps, and an improved viewing experience.

How to update your LG TV firmware

Assuming your TV is turned on, hit the settings button on the remote.

LG TV Remote Settings Button

Now you will see the setting menu on the TV’s left-hand side (Please note that this may vary depending on the model of your LG TV).

You should see the All settings button at the bottom of the row of icons. Please select this option to proceed to the following menu.

Now navigate down to “SUPPORT” on the new menu that appears and then select “SOFTWARE UPDATE”

Method 7: Use an Ethernet cable rather than Wi-Fi

To reduce LG TV streaming issues, an ethernet cable is a better option than using a Wi-Fi connection.

Wired connections transmit data quicker and with less interference.

Wi-Fi connections are slower and generally have a slower response time.

The distance from your playback device, along with the walls, floors, and ceilings, can all deteriorate the quality of your internet connection, causing LG TV speed test issues.

I always use a wired connection when available, and you should too!

Method 8: Disable any ad blockers or VPNs

VPNs and ad blockers can negatively affect the playback performance of your LG TV and cause lagging.

Your connection to a VPN will always limit the speed at which you can play content.

We understand that using a VPN can be a sensible choice, mainly due to privacy concerns.

Unfortunately, by using a VPN, you are creating another dependency that can cause LG TV lagging.

Method 9: Upgrade your Internet Connection

Not everyone has access to high download speeds through their ISP (Internet Service Provider), but for those that do, consider upgrading your internet connection.

It should go without saying that a connection with 100 Mbps will have a slower download speed than one with 1 GBPS.

Method 10: Upgrade your Router

If you have had the same router for a while and have upgraded your internet connection numerous times, you may wish to check the maximum download speeds for your router.

You want to ensure your router can utilize the download speeds you pay for.

A router bottleneck is an unlikely but possible cause of LG TV lagging.

Method 11. Reset Factory Settings

If none of the steps above work, you have no choice but to perform a factory reset on your TV. This will erase all settings and data, so back up all important data before proceeding. 

Please note that this is the last-resort option and should only be used when the situation demands it. 

How to perform a factory reset on LG TV

Go to Settings > Support > Self Diagnosis > Reset.

Method 12: Contact LG TV Support

If you have tried all the steps and your LG TV is still experiencing lagging issues, it may be time to contact LG support with your problem.

The support staff will be able to look more closely and provide more solutions to fix this problem.
