Last Updated Jun 2, 2022

If you notice that your LG TV’s resolution is grainy or “pixelated,” fear not: you can change the settings. This involves going to the DISPLAY menu, pressing a few buttons, and then bang! Perfect, crystal-clear movies, shows, and photos.

Continue reading to learn more about adjusting the resolution on your LG TV. You have two options for adjusting the settings: you can use the remote or use your smartphone. The steps are slightly different but render the same results.

How to Change Your LG TV’s Resolution with the Remote

With the remote, you can change your TV’s resolution by:

  1. Pressing the home button.
  2. Choosing “SETUP”
  3. Clicking “DISPLAY.”

From here, you can select which option works best.

How to Change Your LG TV’s Resolution with Your Smartphone

If you have an LG smart TV, you can control it using your smartphone. To do this, download the LG ThinQ app. You can download it from the Apple App Store or the Google Play Store, depending on what phone you have.

Then, after ensuring that your phone and TV are on the same Wi-Fi network:

  1. Turn on your TV.
  2. Open the app.
  3. Tap the “+.”
  4. Read through the information and tap “OK.”
  5. Select “Home Appliances.”
  6. Choose your TV.
  7. Enter the verification code on the TV into your phone.
  8. Choose “OK.”
  9. Tap “move to home.”

Now, using the steps listed in the previous section, you can change the resolution on your TV.

How to Change the LG TV’s Resolution Manually

Lost the remote? Don’t want to download the app? No problem. Depending on what type of LG TV you have, you can make changes manually. This largely depends on whether your TV has a control panel. It’ll be located either on the bottom or side of the TV.

Here, by locating the “Menu,” you can navigate to “SETUP,” just like in the sections listed above. Remember: many LG smart TVs have an on/off button, but not a control panel like old-school TVs have.

So, if you can’t locate your TV’s control panel, it probably doesn’t have one. Honestly, you’re better off using the app.

What If My LG TV’s Resolution is Still Bad?

If you configured your TV’s resolution and it’s still blurry, consider the following:

It Might Be the App––Not the TV

Suppose you’re trying to watch TV on your Amazon Firestick, and the picture’s still blurry. The problem might not be with your LG TV; it might be with the device. Most streaming devices (i.e., Roku, Apple TV, etc.) adjust to your TV’s resolution when you plug them in.

However, if they don’t, you can adjust those settings from the streaming device’s menu. The specific instructions largely depend on what type of device you have.

You Can Reset Your TV

LG says that if your picture’s still blurry, you should:

  1. Press the mute button three times.
  2. Choose “AV” reset.
  3. Wait one minute.

An AV reset restores your TV back to factory settings.

Identify Any External Factors

External factors could affect your TV’s picture. For instance, if there’s a glare reflecting off the screen, this could affect the picture’s presentation. LG recommends placing your TV away from any windows, mirrors, or light sources for the best possible viewing experience.

Something’s Wrong with Your TV

Sometimes, the problem isn’t you; it’s the TV. If you purchased your LG TV within the last year, it’s still under warranty. In this case, LG may repair or replace your TV at no cost to you. The warranty does not cover DIY “mods” or external issues, like a cracked screen. It generally only covers factory-specific flaws.

What Resolution Works Best for LG TVs?

Essentially, you want the resolution option with the highest number. However, to better understand this, you’ll need a basic understanding of what resolution is and how it works.

Every image on your TV screen comprises pixels; these pixels are measured in lines. The more lines of pixels, the better the picture. For instance, suppose you have one TV with 1080 pixel lines and another with 780 pixel lines. The TV that’s 1080 pixels has better resolution. The better the resolution, the better the picture you see on your screen.

You want to utilize as many pixels as possible, so when choosing the best resolution for your LG TV, you want the resolution with the highest number. Most LG TVs come with these resolution settings, beginning from the best picture quality to the lowest picture quality: 

  • 1080p. The “p” stands for progressive scanning. This is ideal for smoother video outputs.
  • 1080i. The “i” refers to interlaced scanning. In layman’s terms, this means your TV’s screen scans every other row of pixels. It’s not bad by any means, but this setting can cause flickering and delays.
  • 720p. Your TV will produce 720 lines of progressive video.
  • 480p. Your TV will produce 480 lines of progressive video.
  • 480. Your TV will produce 480 lines of interlaced video.

You may have more options, depending on how recently you purchased your TV. Also, feel free to experiment with different resolutions. Some apps and channels may work better with other resolution settings than others.

Final Thoughts

You have two basic options for changing the resolution on your LG TV: you can use your remote, or you can use the LG ThinQ app. Make sure you know what resolution you’re looking for before you make any changes.
