Can I Increase Refresh Rate on My 4K TV?

Yes, you can increase the refresh rate on a 4K TV, but the possibility depends on the model, display settings, and connected devices. Some 4K TVs support variable refresh rates, while others are limited by their native hardware.

Below, we’ll explore how to adjust the refresh rate, what factors influence it, and why higher refresh rates matter.

Can All 4K TVs Support Higher Refresh Rates?

Not all 4K TVs can handle higher refresh rates.

Many models are capped at 60Hz, especially those in the budget category.

However, mid-range to high-end models often support refresh rates of up to 120Hz or higher.

To determine if your 4K TV supports a higher refresh rate, refer to the manufacturer’s specs.

Look for terms like “native refresh rate” or “motion enhancement”—which may list the maximum refresh rate available.

60Hz TVs: Most basic models.
120Hz TVs: Common in mid-range and high-end models.
240Hz TVs: Rare and typically found in high-end gaming setups.

But how?

Here are some ways you can try:

Method 1: Adjusting Through TV Settings

To adjust the refresh rate, navigate through the TV’s display or picture settings.

Open the settings menu on your 4K TV.
Select Display or Picture settings.
Look for Refresh Rate or Motion Settings.
Set it to the highest supported refresh rate (usually 120Hz if available).

If the option isn’t visible, your TV might be limited to a specific refresh rate.

Method 2: Adjusting Through Connected Devices

If you’re using devices like gaming consoles or streaming boxes, their output refresh rates need to be compatible with your TV.

Xbox Series X and PlayStation 5: Both support 4K at 120Hz if connected to a TV that can handle it.
PC Users: You may adjust the refresh rate by accessing the display settings in your computer’s control panel.

Note: Ensure the HDMI cable is rated for high-bandwidth transmission (HDMI 2.1) to support 4K at 120Hz. Lower-grade HDMI cables might not handle high refresh rates effectively.

Do Higher Refresh Rates Make a Noticeable Difference?

For most viewers, increasing the refresh rate from 60Hz to 120Hz is highly noticeable during fast-moving content, particularly in gaming or sports.

Casual TV watchers, especially those watching standard movies or TV shows, may not notice as much of a difference.

However, gamers and sports enthusiasts often report a significant improvement in the overall visual experience.

A 120Hz refresh rate decreases the input lag, providing faster reaction times and a smoother gameplay experience.

Additionally, in games that support frame rates over 60fps, such as Call of Duty or Fortnite, a 120Hz refresh rate provides a substantial competitive advantage.

Here Are Some Considerations Before Increasing Refresh Rate:

Content Compatibility: Not all streaming services, apps, or channels support higher refresh rates. Ensure your primary content can benefit from 120Hz before upgrading.
Device Compatibility: Verify if your gaming console or streaming device can support higher refresh rates. Without this, a higher refresh rate on the TV won’t make a difference.
Cable Quality: Ensure your HDMI cable is rated for high bandwidth (HDMI 2.1) to handle increased refresh rates.
