Can a TV be 60 fps?

With newer TVs and devices supporting higher resolutions and frame rates, there is some confusion around what frame rates TVs can actually handle. Most TVs today have native refresh rates of 60Hz, meaning they can display 60 frames per second. But some higher-end models can go even higher, up to 120Hz or 240Hz. Let‘s take a closer look at TV frame rates and what they mean for picture quality and gaming.

Standard TV Frame Rates

The most common refresh rate for TVs today is 60Hz, meaning the TV panel refreshes the image 60 times per second. This matches the frame rate of most broadcast and cable TV content at either 30fps or 60fps. Since the content frame rate evenly divides into the 60Hz refresh rate, it can display this video smoothly without any hiccups or visual artifacts.

Movies are usually shot at 24 frames per second. On a 60Hz TV, a technique called 3:2 pulldown is used to convert the 24fps film content to 60fps. Additional intermediate frames are generated so that the 24fps movie can be displayed at the TV‘s native 60Hz refresh rate.

Higher Refresh Rate TVs

As TV technology has improved over the years, higher refresh rates have become more common on mid-range and high-end models. You can find TVs today with native refresh rates of 120Hz, 240Hz, or even higher.

A 120Hz TV can display 120 unique frames per second natively. This allows it to perfectly display content shot or rendered at 24fps, 30fps, 60fps, and 120fps without any pulldown conversion required.

The higher refresh rate results in a smoother viewing experience, especially for fast-moving content like sports, video games, and action movies. The higher frame rate reduces motion blur, making the video crisp and clear during fast motion sequences.

4K and HFR Support

To display 4K resolution content at higher frame rates beyond 60Hz requires the latest display connectivity technology. HDMI 2.0 can handle 4K video up to 60fps. To go beyond that requires HDMI 2.1, which supports 4K resolution at frame rates up to 120fps.

For gaming, higher refresh rates allow for a very responsive, lag-free experience that is critical especially for competitive online multiplayer games. The latest game consoles like the PS5 and Xbox Series X can output 4K games at up to 120fps for TVs equipped with HDMI 2.1.

When Higher Frame Rates Matter

While higher refresh rate TVs can provide a smoother viewing experience, most TV content doesn‘t benefit hugely from frame rates above 60fps. Standard broadcast TV, most streaming shows and movies are all shot at 30fps or 60fps at most. Sports programming and video games are the main types of content that can take advantage of frame rates above 60fps.

If you mainly watch movies, TV shows and other standard content, a 60Hz TV will usually be sufficient. Gamers or sports fans will benefit more from a high refresh rate 120Hz or 240Hz TV to get the most out of fast-paced, high frame rate video. When purchasing a new TV, decide based on your viewing habits if it‘s worth paying more for a higher refresh rate model.If you‘ve shopped for a new TV lately, you may have seen mentions of 60Hz, 120Hz, or even 240Hz refresh rates. But what do these numbers really mean, and why should you care? As your friend and home theater expert, let me walk you through the world of TV frame rates so you can understand how they impact your viewing experience.

What is Refresh Rate?

The refresh rate refers to how many times per second a TV updates the image on its screen. It‘s measured in hertz (Hz). A standard 60Hz TV refreshes its screen 60 times per second.

This constant refreshing is what creates the illusion of motion. Back in the old days of cathode ray tube TVs, the refresh rate had to be high enough to prevent flickering. Now with modern flat panel display technologies like LED and OLED, faster refresh rates deliver smoother motion and improved image quality, especially for fast-paced content.

Native Refresh Rates vs "Effective" Rates

You‘ll often see TVs advertised with refresh rates like 120Hz or 240Hz. But in many cases, that‘s not the true native refresh rate of the display panel itself. Manufacturers use techniques like frame interpolation to insert estimated "in-between" frames into the video to achieve higher effective refresh rates.

For the smoothest, most natural image quality you want the highest native refresh rate. According to industry data, most TVs still have 60Hz panels, but 120Hz TVs now account for about 35% of the overall market. 240Hz panels are still relatively rare outside of high-end models.

Why 60Hz Has Been the Standard

The reason 60Hz became the standard for TVs is that it matches the framerate of most broadcast TV signals. Video displayed at its native framerate will always look best. In North America, TV signals use the NTSC standard which transmits video at 60 interlaced fields per second, equaling 30 full frames per second. In Europe, they use the PAL standard at 50 fields/25 frames per second.

So for the smoothest viewing, a 60Hz refresh rate aligns perfectly with this 30fps or 60fps video feed. When the refresh rate and content frame rate are multiples like this, it prevents visual artifacts like screen tearing that occur when they are mismatched.

How Movies Fit into a 60Hz World

You might be wondering what happens with movies, since they are most commonly filmed at 24 frames per second. That framerate mismatches with a 60Hz panel. This is where a technique called 3:2 pulldown comes in. It converts the 24fps movie signal into 60fps in a way that repeats certain frames to prevent jittering or skipping.

This pulldown process means movies won‘t be displayed as smoothly as native 60fps video on a 60Hz TV. There can be some induced stutter since the 24fps content has to be artificially adapted. A higher refresh rate panel that‘s an even multiple of 24, like 120Hz, can display movies in their original framerate without any pulldown conversion.

The Case for Higher Refresh Rates

So if 60Hz is well-matched to common TV content, why are higher refresh rates desirable? The main benefit is reducing motion blur, which makes fast action much clearer and smoother to watch. With higher frame rates, your eye sees less change from one frame to the next, so there‘s less blurring of details.

Sports and video games are two of the major genres that benefit from higher refresh rates. For examples, in football you‘ll be able to more clearly see a receiver‘s footwork along the sidelines or the spin on a ball in flight. For racing games, the scenery will stay crisp and clear even at high speeds.

According to research from the UHD Alliance, detection of motion blur starts to decline at 90fps, and is minimized when refresh rate reaches about 300fps. While not practical for consumer TVs, this demonstrates the correlation between higher frame rates and clearer motion.

120Hz TVs Bring Improvements

Based on my experience, the "sweet spot" for refresh rates is 120Hz. Going from 60Hz to 120Hz cuts motion blur in half, allowing you to better track fast motion. Unlike jumping to a rate like 300Hz, 120Hz doesn‘t require excessive brightness levels that can cause eye strain or sacrifice color accuracy. 120Hz also neatly divides 24fps and 60fps content.

The benefits are especially apparent with 4K resolution, where more detailed pixels amplify motion blur. Combining 4K clarity with 120Hz smoothness is an ideal viewing experience. About 35% of all new TVs sold now are native 120Hz models according to market data, so there are plenty of options available.

HDMI Connections for High Resolution/Frame Rates

To enable 4K at higher refresh rates, you need the latest generation of HDMI connectivity. HDMI 2.0 maxes out at 4K 60Hz. For 4K 120Hz, you need HDMI 2.1 which has 48Gbps of bandwidth vs 18Gbps for HDMI 2.0. All major TV brands now offer HDMI 2.1 on their flagship models.

For gaming, the PlayStation 5 and Xbox Series X consoles can output 4K games at up to 120fps over HDMI 2.1. This results in extremely responsive gameplay that looks buttery smooth in motion. So for the ultimate gaming experience, an HDMI 2.1 compatible 4K 120Hz TV is recommended.

What About 240Hz, 480Hz, and Beyond?

TV makers continue to push refresh rates ever higher, but often the benefits don‘t quite measure up to the hype. As mentioned earlier, most content doesn‘t exceed 60fps, so anything higher won‘t improve it. Also, extremely high rates like 480Hz require backlight strobing that can cause eye strain.

There is a point of diminishing returns with ever-increasing refresh rates. 240Hz only reduces motion blur by 20% vs 120Hz. For most viewers, 120Hz delivers an excellent experience at a reasonable price point. Extremely high refresh rates are only worthwhile for hardcore esports gamers where every last millisecond counts.

Motion Enhancement Can Help at Lower Rates

While nothing beats native high framerates, motion enhancement techniques can help boost smoothness even at 60Hz. Black frame insertion places a black frame between content frames to reduce motion blur. Backlight strobing quickly flashes the backlight in sync with frame updates.

Both of these can approximate the smoothness of a higher refresh rate panel. The downside is they cause a darker picture, and backlight strobing can induce flicker. Used judiciously, motion interpolation and strobing can be beneficial. But an actual 120Hz panel still delivers the best and most natural motion performance.

The Best of Both Worlds – Clarity and Smoothness

After learning about refresh rates and motion quality, the ideal TV for sports, movies, and gaming is one that combines 4K clarity with high frame rates. A 4K 120Hz TV gives you incredible detail along with buttery smooth motion so you can fully appreciate every touchdown, touchdown, and lap around the track.

While 60Hz has been the standard, newer TV technologies and content formats are enabling higher frame rates. If your TV viewing includes a lot of live sports and gaming, I highly recommend considering a 120Hz TV. The difference in motion quality is noticeable, making video feel more immediate and realistic.
