Vizio TVs are well-known for their affordable prices and impressive picture quality. If you’re the owner of a Vizio TV and you’re wondering how to enable 120Hz, you’ve come to the right place. In this guide, we’ll explain what 120Hz is, why it’s important, and how to enable it on your Vizio TV.

What is 120Hz?
Before we dive into the details, let’s first understand what 120Hz means. The refresh rate of a TV determines how many times the image on the screen is updated per second. For example, a 60Hz TV refreshes the image 60 times per second, while a 120Hz TV refreshes it 120 times per second. This means that the 120Hz TV can display more frames in the same amount of time, resulting in smoother motion and reduced motion blur.
Why is 120Hz important?
If you’re a fan of sports or action-packed movies, you’ll appreciate the benefits of a high refresh rate. A 120Hz TV can display fast-moving objects more smoothly, making the action easier to follow and reducing the blur that can occur on lower refresh rate TVs. Additionally, 120Hz can provide a more immersive gaming experience, as it reduces input lag and motion blur, allowing you to react faster to in-game events.
How to enable 120Hz on Vizio TV?
Now that we understand the benefits of 120Hz, let’s dive into how to enable it on your Vizio TV.
Step 1: Check the TV’s specifications
The first step is to check if your Vizio TV supports 120Hz. Not all Vizio TVs have a 120Hz refresh rate, so it’s essential to check your TV’s specifications to confirm if it supports it. You can typically find this information in the TV’s manual or on the manufacturer’s website.
Step 2: Check the source
Even if your Vizio TV supports 120Hz, you may not be able to take advantage of it if the source material doesn’t support it. For example, most cable and satellite TV channels only broadcast at 60Hz, so you won’t see any benefit from a 120Hz TV when watching those channels. However, some streaming services and video game consoles do support 120Hz, so it’s worth checking if your sources can take advantage of it.
Step 3: Enable Game Mode or PC Mode
If your Vizio TV supports 120Hz and your source material does too, the next step is to enable Game Mode or PC Mode. These modes disable post-processing effects on the TV, which can add lag and reduce the refresh rate. Enabling Game Mode or PC Mode can also reduce input lag, which can be beneficial for gaming.
To enable Game Mode or PC Mode, follow these steps:
- Press the Menu button on your Vizio TV remote.
- Navigate to the Picture Settings menu.
- Find the Game Mode or PC Mode option and select it.
- Enable the mode.
Step 4: Enable 120Hz
Once you’ve enabled Game Mode or PC Mode, you can then enable 120Hz. Follow these steps:
- Press the Menu button on your Vizio TV remote.
- Navigate to the Picture Settings menu.
- Find the Refresh Rate option and select it.
- Choose 120Hz.
If you can’t find the Refresh Rate option, it may be because your Vizio TV automatically detects the source material’s refresh rate and adjusts the TV’s refresh rate accordingly. In this case, if your source material supports 120Hz, your TV should automatically switch to 120Hz.
