Do 4K 120Hz TVs exist?

4K 120Hz TVs certainly do exist, but having a TV with HDMI 2.1 ports that support 4K resolution at 120Hz refresh rate is just part of the equation. To truly benefit from 4K 120Hz for gaming or movies, you need source devices that can output 4K content at high frame rates. This requires modern GPUs in gaming PCs, the latest consoles like PS5 and Xbox Series X, and very few movies/streaming services provide 4K 120fps content.

What is 120Hz refresh rate?

The refresh rate of a display determines how many times per second it updates to show a new image, measured in hertz (Hz). Standard TVs and monitors have a 60Hz refresh rate. 120Hz displays update twice as often, showing 120 frames per second. This results in much smoother motion clarity with less blurring of fast movement. 120Hz is considered the sweet spot for most displays, providing noticeable improvements in gaming, sports and movies over 60Hz.

Do 4K 120Hz TVs provide any benefits?

A 4K resolution screen with 120Hz refresh rate allows for extremely smooth, sharp motion clarity. Video games running at high frame rates of 120fps can take full advantage of 120Hz displays by synchronizing the TV‘s refresh rate to the game‘s frame rate. This reduces input lag, screen tearing and delivers an ultra smooth gaming experience.

4K 120Hz is also beneficial for sports programming and some movies where scenes contain fast dramatic motion. The higher refresh rate keeps the action looking crisp and smooth, rather than blurred. Keep in mind most content is still 60Hz, so the benefits are dependent on your media and devices outputting 120fps.

What do you need for 4K 120Hz?

To experience 4K resolution at 120Hz refresh rate requires:

• A 4K TV or monitor with HDMI 2.1 ports that support 4K 120Hz input.
• Source devices like gaming PCs, PS5, Xbox Series X that can output 4K video at high frame rates of 120fps or more.
• HDMI cables rated for 48Gbps to handle the high bandwidth signal.

Without all three of these elements, you won‘t be able to fully take advantage of 4K 120Hz. Most standard 4K TVs and monitors only have HDMI 2.0 ports limited to 60Hz at 4K. So it‘s important to check specifications for HDMI 2.1 support.

Gaming Performance at 4K 120Hz

For gaming PCs, you will need a high end modern GPU like the NVIDIA RTX 3080 or AMD RX 6800 and above to power the latest games at 4K resolution and 120+ fps frame rates. The extra responsiveness and fluidity of 120Hz makes for a super smooth gaming experience.

The Xbox Series X and PS5 consoles also support 4K 120fps gaming if you have a compatible 120Hz TV. There is a growing list of games being optimized for 4K 120fps, particularly multiplayer competitive titles where the lightning fast response can give players an edge.

While 60fps is fine for many single player games, competitive fast paced online shooters really benefit from 120fps at 4K resolution. The difference in fluidity and responsiveness between 60Hz and 120Hz is quite noticeable when playing at high frame rates.

What about 4K 144Hz or 240Hz?

4K monitors are now available with 144Hz and even 240Hz refresh rates. However, powering 4K games at extremely high frame rates requires the most powerful GPUs like the RTX 3090 Ti or Radeon 6950 XT. There are diminishing returns past 120Hz at 4K resolution. You have to balance visual fidelity and frame rates.

For competitive esports gamers, 1080p 240Hz monitors are a good fit for achieving those sky high frame rates above 200fps. While 4K 144Hz monitors future proof for the next generation of GPUs that can push closer to 144fps consistently.

Is a 4K 120Hz TV good for PS5 and Xbox Series X?

The PS5 and Xbox Series X aim to deliver 4K gaming at 60fps or up to 120fps. A matching 4K TV with 120Hz refresh rate, VRR (variable refresh rate) and low input lag is recommended to take full advantage of what these new consoles can offer.

Fast paced shooters like Call of Duty, racing sims like Forza Horizon and other twitch gameplay genres see the most benefit from high fps. While cinematic story driven games can still look stunning at 4K 60fps. Checking for PS5/Xbox optimized titles and their performance modes will let you know which games support 120fps.

What about movies and TV shows?

Most movies and streaming TV content is still standard 60Hz video. Sports programming will have the most examples of fast intense motion that can benefit from 120Hz clarity. But majority of media is 24fps to 30fps so you won‘t see dramatic improvements for films and shows on a 120Hz display. Movies are presented at a cinematic 24fps for a film look, which actually gets converted to 60Hz signal.

120Hz really shines for gaming where the PC or console is outputting a high 120fps frame rate to match the TV‘s capabilities. This is what gives such a noticeable boost to smoothness and responsiveness compared to 60Hz.

For media consumption, 4K resolution is more impactful than high refresh rates. A 4K OLED TV will provide stunning image quality that immerses you in movies and shows, even at standard 60Hz.

Do I need a 120Hz TV for PS5 or Xbox Series X?

You don‘t absolutely need one. These new consoles are designed for 4K 60Hz TVs which will look beautiful with optimizations for graphics and performance. However, to experience the max frame rates supported in some games, a 120Hz TV is recommended.

For multiplayer titles like Call of Duty and Fortnite where hitting the highest fps provides a competitive edge, a 120Hz display paired with a PS5 or Xbox Series X will give you an advantage. Sony and Microsoft are promoting 120fps gameplay as a big feature of this generation. So a 120Hz TV helps realize the full potential.

Should I get a 4K 60Hz or 1080p 120Hz monitor for gaming?

This depends on your priorities and the power of your PC‘s graphics card. Here are factors to consider:

– 4K 60Hz will provide the sharpest image quality and highest resolution. Ideal for story driven single player games.

– 1080p 120Hz allows for ultra smooth frame rates above 100fps. Competitive multiplayer games benefit most from high refresh.

– What GPU do you have? If playing at 4K, you will need at least an RTX 3070 / RX 6800 to hit 60fps in demanding games.

– Monitor size and viewing distance matter. On smaller 27" screens or when sitting farther away, 4K provides less benefit.

– 1080p on a large monitor may look more pixelated up close compared to 4K.

There are also 1440p 144Hz monitors which balance quality and performance. Ultimately both 4K 60Hz and 1080p 120Hz are great options suitable for different gaming needs.

Do 4K TVs support 1080p at 120Hz?

Yes, most 4K TVs with 120Hz refresh rates also support 1080p resolution at 120Hz through their HDMI ports. This is handy for older game consoles like the Xbox One X and PS4 Pro which can output 1080p at 120fps.

Getting a new 4K TV with 120Hz support provides an upgrade path for both current and next gen game systems. You can play older 1080p games at high refresh, and new 4K games at 60Hz or 120Hz. Just be sure to check your particular TV’s specs to confirm 1080p 120Hz is enabled on the HDMI inputs.

Things to check for 4K 120Hz support:

As a tech enthusiast and avid gamer, you may have heard about 4K resolution televisions with 120Hz high refresh rates that promise an incredibly smooth, responsive gaming experience. But are these too good to be true? Do 4K 120Hz TVs actually exist on the market today?

I‘m thrilled to tell you that YES – real, true 4K 120Hz TVs are absolutely available from multiple manufacturers! However, unlocking the full potential of 4K 120fps gaming requires specialized gear and know-how.

In this comprehensive guide, we’ll demystify 4K 120Hz displays, what it takes to power them, their benefits for gameplay, and how to choose the perfect high performance TV or monitor for your needs. Let‘s dive in!

## HDMI 2.1 – The Key to 4K 120Hz

In order to achieve 4K resolution at 120Hz refresh rates, your display must have HDMI 2.1 ports. This latest HDMI specification provides the high bandwidth needed to handle those blazing fast frames.

HDMI 2.1 increases maximum bandwidth to 48 Gbps – a huge leap over 18 Gbps of HDMI 2.0. This opens the floodgates for uncompressed 8K video and 4K gameplay at 120fps with HDR enabled. Other enhancements include:

* Support for eARC (enhanced audio return channel)
* Dynamic HDR formats
* Up to 10K resolution at 120Hz!
* Variable refresh rate (which we‘ll discuss soon)

For now, it‘s important to know that ONLY HDMI 2.1 has enough oomph to push 4K 120Hz. So when TV shopping, look for displays with HDMI 2.1 ports. Many don‘t have this yet, so it‘s still a premium feature limited to higher-end models.

## What difference does a higher refresh rate make?

You‘re probably familiar with the standard 60Hz refresh rate on today‘s TVs. This means they redraw the entire screen 60 times per second. Jumping up to 120Hz doubles this rate, for a total of 120 complete image refreshes every second.

Now why does this matter? The higher the refresh rate, the smoother and more fluid the motion appears. Objects that are moving across the screen, like a racing game or a football player running down the field, will appear less blurry and more sharply rendered at 120Hz.

It comes down to our human eyesight being able to perceive and track motion better when the image refreshes more rapidly. 120Hz is considered the sweet spot that maximizes smoothness without going overkill.

## Just How Much Smoother is 120Hz over 60Hz?

It may seem subtle on paper, but the difference between 60Hz and 120Hz is quite dramatic when seen side by side. Gameplay appears significantly more fluid, crisp and lifelike at the faster rate.

To quantify the improvements, industry tests have measured:

* **Up to 50% reduction in motion blur** – Objects exhibit less ghosting and blurring as they move across the screen.

* **33% less input lag** – The delay between controller and on-screen response is radically shorter. This means much snappier reflexes for competitive multiplayer.

* **60%+ higher visibility of critical details during fast motion** – A 120Hz refresh provides clearer visuals when tracking fast-moving targets compared to 60Hz. You can literally see more temporal detail.

The boost in smoothness and sharpness when panning the camera, tracking enemies, or driving at high speeds is immediately apparent. Once experienced, many gamers consider 120Hz indispensable and struggle to go back to 60Hz!

## For Gaming, Frame Rate Matters As Much As Refresh Rate

Now, to enjoy the benefits of 120Hz, the content you‘re viewing also needs to play at native frame rates of 120fps (or even higher). This is where gaming PCs and the latest consoles come in.

The PlayStation 5 and Xbox Series X are designed to support 4K gaming at up to 120fps. This matches beautifully with a 4K TV running at 120Hz. When the TV‘s refresh rate syncs with the console‘s frame rate output, you get that super fluid motion.

On the PC side, rendering games in 4K at 120+ fps requires serious graphics horsepower. You’ll need one of the latest NVIDIA 3000 series or AMD 6000 series graphics cards. A GeForce RTX 3080 or Radeon RX 6900 XT are good targets for smooth 4K 120Hz gameplay.

Interestingly, many competitive esports gamers prefer 1080p resolution with extremely high 240Hz refresh rates. This allows their PCs to push frame rates up over 200fps for outrageously fluid motion!

## 4K 120Hz for Cinematic Story Games and Fast Competitive Multiplayer

The benefits you’ll see from 4K 120Hz depend on the genre and pacing of the game. For cinematic story driven games meant to look like movies, 4K 60Hz is often ideal. This provides pin sharp visuals and smooth animations just like 24fps films.

However, competitive online shooters and fighting games thrive at 120fps. The radically reduced input lag and crystal clear motion allow players to react quicker and track targets more accurately. When milliseconds matter, 120Hz can provide a real edge.

Racing games also emphasize smoothness and responsiveness where high frame rates excel. Speeding along detailed 4K tracks at 120fps in a Forza or Gran Turismo game is an absolute thrill!

So while not every game needs the high frame treatment, 4K 120Hz unlocks options. You can enjoy both immersive high-res cinematics AND liquid smooth competitive play on one display.

## What About TV Shows, Movies and Streaming – Do They Benefit from 120Hz?

Great question! The content you watch also factors in. Most television programming and films are still standardized at 60Hz. So a 120Hz television won’t make those look smoother.

However, one genre that DOES benefit from 120Hz clarity is sports. Viewing sports at 120fps helps capture all the detail of dramatic fast motion that occurs in football, hockey, basketball and more. You’ll catch more player and ball movements with a crisper, clearer picture.

As for streaming shows and movies, even at 60Hz they will look fabulous at full 4K resolution. Focus on image quality technologies like OLED contrast, HDR and Dolby Vision over refresh rates for cinematic content.

## Do You Need HDMI 2.1 Cables for 4K 120Hz?

To enjoy full 4K 120Hz from your HDMI 2.1 source devices into your HDMI 2.1 TV or monitor, you WILL need new Ultra High Speed HDMI cables rated for 48Gbps.

Many owners make the mistake of trying to use old HDMI cords, only to be limited to 4K 60Hz. Don’t blow hundreds on a new TV only to hamstring performance with outdated cables! Be sure to get 48Gbps certified HDMI wires.

## What About Gaming Monitors – Do 4K 120Hz Models Exist?

Gaming monitors with 4K 120Hz support absolutely exist from brands like ASUS, Acer and LG. Just like on the TV side, you’ll want to look for models with HDMI 2.1 or DisplayPort 1.4 to unlock the highest 4K frame rates.

Monitors have traditionally had higher refresh rates than TVs, with speedy 1080p 144Hz – 240Hz models common. Now we are seeing the first 4K 144Hz monitors emerge capable of 144 fps gaming.

The catch is you need an incredibly powerful PC and GPU combo to push triple digit frame rates at such a high resolution. Cool tech preview for the future though!

## Why Variable Refresh Rate Matters for Smooth Gaming

To complement their 120Hz capabilities, many new TVs also include variable refresh rate technology (VRR). This synchronizes the monitor‘s refresh rate to the actual frames being rendered by the game.

Why does this help? Game engines often render frames at inconsistent intervals that fluctuate based on scene complexity. VRR smooths out those natural dips and spikes to reduce stuttering and screen tearing.

Enabling VRR provides an even smoother 120Hz experience untethered from constant frame times. The HDMI 2.1 spec accommodates VRR signals.

## Auto Low Latency Mode for Fast Response

One other awesome innovation available on HDMI 2.1 TVs is ALLM – auto low latency mode. This automatically switches the display into its fastest response time preset when you begin playing a game.

Input lag refers to the delay between hitting a button and seeing the result on screen. Keeping this as low as possible is critical, especially in competitive online games.

ALLM ensures your display is ready for those hair-trigger reactions without having to manually change settings. Just start the game and it kicks into fast mode. Sweet!

## What About HDR – Is It Supported at 4K 120Hz?

You‘ll be pleased to know that 4K 120Hz works simultaneously with HDR for an image quality double whammy! The widened color gamut and enhanced contrast of HDR combined with the temporal clarity of 120Hz is outstanding.

Now this demands a lot of processing power and bandwidth. So compromises like 4:2:0 chroma subsampling are often used to squeeze both 4K 120Hz and HDR through the HDMI 2.1 pipeline.

Peak brightness is also an important HDR trait – look for TVs capable of 1000 nits or higher. And of course excellent full array local dimming takes HDR to the next level.

## Do You Need a 4K 120Hz TV to Enjoy Next-Gen Gaming Consoles?

This depends on the games you play. The PlayStation 5 and Xbox Series X are designed to deliver gorgeous 4K gaming at 60fps. For more cinematic single player experiences, a standard 4K 60Hz TV is perfect and widely available.

However, to access the bleeding edge 120fps performance in supported competitive multiplayer titles, you WILL need a compatible 4K 120Hz display. So if you‘re a hardcore online gamer who wants every possible advantage, investing in 4K 120Hz makes sense.

The good news is that these new consoles can also take advantage of gaming features like VRR and ALLM over HDMI 2.1. This really unlocks their full potential.

## What About a 1080p 120Hz Display – Does Resolution Matter?

This is another great option! You‘ll also find tons of high performance 1080p gaming monitors with super fast 120Hz, 165Hz or 240Hz refresh rates.

The benefit here is it‘s MUCH easier for a console or PC to render games at 100+ fps when working at the lower 1080p resolution vs 4K. You can enjoy extra smooth motion without the heavy 4K rendering workload.

Image quality does take a hit on a larger screen. But for competitive multiplayer, lightning reflexes and tracking accuracy trump resolution. Pros will gladly sacrifice sharpness for speed!

## Things to Look for When Shopping for a 4K 120Hz Display

Okay, let‘s recap the key features that enable the best 4K 120Hz gaming experience:

* Native 120Hz refresh rate

* HDMI 2.1 input ports

* Low input lag (10ms or under is great)

* VRR (variable refresh rate)

* ALLM (auto low latency mode)

* High peak brightness (1000+ nits)

* Full array local dimming with ample zones

* DisplayPort 1.4 for PC / laptop gaming

Of course picture quality traits like contrast, black levels, viewing angles and color depth remain important too. OLED is hard to beat for its infinite contrast and true blacks.

Prioritize the refresh rate, connectivity and gaming features first. Then choose between LED LCD, QLED or OLED to suit your budget. There are now great options across the price spectrum.
