Enhance LG Tv Speed: Step-by-Step Guide

It’s frustrating when tasks on your LG TV are delayed due to slow speed. Fortunately, there are several methods you can use to tackle this issue.

Reasons for Slow LG TV Performance

Before jumping to the solutions, you must explore the reasons behind this issue. This way, you can effectively avoid encountering similar issues in the future.

Slow Internet Connection or Network Issues

Smart TVs function properly only on stable and fast internet networks. An unstable or weak network can cause your TV to perform slowly. Additionally, weak signals can also affect your viewing experience.

To resolve the slow internet issue, follow these steps:

Restart your router

To restart your router, follow these steps in sequence:

  1. Locate and press the Power button on the router.
  2. Unplug the router from the power outlet after it has turned off.
  3. Keep it unplugged for 15-20 seconds, then plug the router back into the power outlet.
  4. Wait for the router to reboot and reconnect to your devices.

Moving the router closer to the smart TV

Some routers may not have a wide enough range to connect with your devices over long distances. Additionally, walls or other obstacles can interfere with the Wi-Fi signal between your TV and router. Bringing the router closer to the TV can help avoid these issues.

Optimizing your Wi-Fi settings

Wi-Fi routers use different frequency bands to avoid signal interference. Check your router’s settings to ensure it’s on the correct frequency.

Using a wired connection

Almost all smart TVs have Ethernet cable ports, which can be used to connect your TV to Wi-Fi via a wired network. To avoid signal interference and ensure a fast and smooth experience, use a wired connection.

After restarting your router and optimizing your Wi-Fi settings, if your LG TV still can’t connect to Wi-Fi, you should contact your internet service provider for further assistance.

Overloaded Storage or Limited Memory

Your LG TV’s speed may become slow due to overloaded storage. Everything installed on your TV consumes a specific amount of storage space. A lot of downloaded apps, files, and other content can contribute to your LG TV’s slowness.

Moreover, your smart TV’s limited random access memory (RAM) can fill up, which may also affect your TV’s performance. There are various methods to clean up memory

Note: You can’t change or upgrade your TV’s RAM because it is directly connected to the motherboard.

Here’s how you can clean up memory:

  1. Uninstall less frequently used apps from your TV, and make sure that closed apps are not running in the background.
  2. Always Remove cache to delete temporary files.
  3. Erase all unnecessary downloaded content, such as pictures and videos. Alternatively, you can move this data to a USB flash drive or external hard drive.

If your LG TV is still experiencing slow performance, you should consider performing a factory reset to clear up storage space. Keep in mind that a factory reset will remove all data stored on your smart TV. Therefore, make sure to back up any important data onto a USB flash drive before proceeding.

Outdated Software

Software is the soul of electronic devices such as computers and smart TVs. If the software becomes old or buggy, it will affect the performance of the device. Make sure that you are using the latest software on your LG TV.
