Can all TVs run 120 fps?

Hey there gaming and tech enthusiast! If you‘re like me, you love experiencing games in the smoothest, most responsive way possible. That‘s where ultra-fast 120Hz displays come in.

In this guide, we‘ll dive deep into the world of 120Hz gaming. I‘ll breakdown exactly what it takes to unlock truly fluid 4K 120 fps gameplay. Let‘s get started!

What is Refresh Rate and Why Does it Matter?

A display‘s refresh rate refers to how many times per second it updates its image. It‘s measured in Hz (hertz). Standard TVs and monitors refresh at 60Hz.

But a 120Hz display refreshes twice as often, at 120 fps (frames per second). This results in much smoother motion clarity and responsiveness.

Here‘s a quick video visually explaining the difference between 60Hz vs 120Hz:

Why does refresh rate matter for gaming? Because higher frame rates directly reduce input lag – the delay between your controller and on-screen actions.

At 60Hz, new frames only get displayed every 16.7ms. But at 120Hz, input lag is reduced to 8.3ms. That‘s up to 50% less lag!

According to detailed input lag testing by DisplayNinja, 120Hz gaming sees average lag reduced from 21ms down to just 10ms compared to 60Hz.

This means much more responsive controls for competitive multiplayer titles like Call of Duty or Fortnite. Even in singleplayer adventures, 120Hz provides a fluidity that just feels next-gen.

The Requirements for 4K 120Hz Gaming

So how can you unlock the ultra-responsive gameplay of 120Hz? There are 3 core requirements:

1. A 120Hz Compatible TV or Monitor

First, you‘ll need a display with an actual 120Hz-capable panel. Many TVs cheat by using motion interpolation to fake a higher "effective" rate.

Make sure yours has HDMI 2.1 ports and specifically lists 3840 x 2160 @ 120 Hz under its supported resolutions. This confirms true 4K 120Hz readiness.

Here are some of the best 120Hz-ready screens I recommend:

The LG C2 OLED and Samsung QN90B Neo QLED are top-tier options providing stunning image quality. Both contain HDMI 2.1 and 120Hz panels capable of 4K gaming up to 120 fps.

For monitors, the Razer Raptor 27 and ASUS PG279QM are excellent 27" options with 120+ Hz refresh rates.

2. A Compatible Console or High-Powered Gaming PC

Next, your gaming platform needs to be capable of high frame rate rendering. This means an Xbox Series X/S, PS5, or a PC with a powerful graphics card.

Here are the GPUs that can reliably hit 120+ fps in demanding games at 4K resolution:

• NVIDIA GeForce RTX 3080 Ti or better
• AMD Radeon RX 6800 XT or better

The extremely smooth 120Hz gameplay demands some serious horsepower from your hardware. But today‘s latest GPUs are up for the challenge.

According to testing by Digital Foundry, the RTX 3080 Ti averages 120-144 fps in Halo Infinite with max settings at 4K. That‘s a great example of properly utilizing an HDMI 2.1 TV.

3. Compatible Cables and Proper Setup

Finally, an Ultra High Speed HDMI 2.1 cable is required to pass the full 4K 120Hz video signal from source to screen.

Make sure to use the TV‘s dedicated HDMI 2.1 ports, and enable any special gaming modes in the TV settings to reduce input lag. Turn off unnecessary post-processing to keep the video path as direct and responsive as possible.

With the right gear, proper setup is crucial to maximize that silky smooth 120Hz goodness!

Why HDMI 2.1 is a Game Changer

Previously, HDMI 2.0 topped out at 4K 60Hz. But the upgraded HDMI 2.1 specification doubles available bandwidth to 48 Gbit/s.

This huge throughput allows features like:

• 4K at 120 Hz
• 8K at 60 Hz
• 10K resolution support
• Dynamic HDR (Dolby Vision)

It‘s this combination of ultra high resolutions and fast refresh rates that really enables next-gen gaming experiences.

Here‘s a chart comparing HDMI versions and their maximum capabilities:

That‘s why you‘ll only find super fast 120Hz support on TVs and monitors with HDMI 2.1. This latest standard provides the pipeline necessary for higher resolutions and frame rates.

Digging Deeper on Refresh Rates

Beyond 120Hz, some screens advertise 144Hz, 240Hz, or even 360Hz. Is more Hz always better? What about diminishing returns?

Here‘s an analysis of refresh rates and whether the differences are actually noticeable:

[insert refresh rate comparison chart]

• 60Hz to 120Hz – A substantial improvement in motion clarity and input lag. Once you game at 120Hz, 60Hz feels sluggish in comparison.

• 120Hz to 144Hz – A smaller incremental upgrade. 144Hz looks slightly smoother, but120Hz already provides excellent fluidity. Still a worthy upgrade for esports pros who want every advantage.

• Beyond 144Hz – Extremely diminishing returns. 200Hz+ refresh rates are mostly just bragging rights. Exceeds what the human eye can perceive.

So while 144Hz or higher seems impressive on paper, I find the 120Hz sweet spot hits the best balance. Unless you‘re a pro gamer, 120Hz delivers that silky gameplay you crave.

120Hz vs 60Hz Input Lag Testing

Exactly how much faster is 120Hz compared to 60Hz when it comes to input lag? Detailed display testing provides some definitive numbers.

According to benchmarks by DisplayNinja, here is how average input lag compares between 60Hz and 120Hz displays:

[insert bar graph comparing 60Hz and 120Hz input lag]

At 60Hz, average input lag across multiple games is 21ms. But at 120Hz, that average lag drops substantially to just 10ms.

That 11ms saved means much snappier response in competitive multiplayer titles like Fortnite or Valorant where every millisecond counts. Even in cinematic singleplayer games, the reduced lag provides a more direct and crisp feel to controls.

So not only does 120Hz reduce perceived motion blur, but it directly speeds up the time between your inputs and on-screen actions. No wonder it feels so much more responsive!

TV vs Monitor – Which is Best for 120Hz?

When it comes to 120Hz gaming, should you use a large 4K TV or smaller high refresh gaming monitor? Let‘s compare the pros and cons of each.

Monitors

Pros:

• Very fast refresh rates (165Hz, 240Hz, etc)
• Smaller screen reduces input lag
• Designed specifically for gaming

Cons:

• Limited to 25-27" screen sizes
• No 4K – 1440p or 1080p only

TVs

Pros:

• Big screen 4K gaming
• OLED TVs provide stunning image quality
• More affordable at large sizes

Cons:

• Input lag typically higher than monitors
• Often limited to 120Hz without interpolation

For intense competitive multiplayer, smaller high refresh monitors still have the edge. But 4K 120Hz TVs now provide a much more cinematic and immersive experience while still being highly responsive.

Ultimately, it comes down to your priorities. Casual gamers will appreciate the jaw-dropping visuals of a big 4K 120Hz OLED. But esports pros may still prefer ultra-fast 240Hz monitors.

Should You Upgrade to 120Hz?

If you‘re still gaming on an older 60Hz display, should you upgrade to the latest and greatest 120Hz screens?

If you frequently play competitive online games, absolutely! The difference is like night and day. Once you‘re used to 120Hz, you‘ll never want to go back to 60Hz. Everything feels more responsive and immediate.

For singleplayer cinematic games, 120Hz provides less of a benefit. The increased smoothness and lower input lag are still nice. But graphics and immersion become more important than sheer speed.

For media streaming and movie watching, 120Hz is mostly overkill. Since movies only run at 24 fps, you won‘t really benefit from refresh rates over 60Hz.

But for gaming, especially fast-paced competitive titles, 120Hz is a massive upgrade! The gameplay revelation is worth leaving 60Hz screens behind.

Cutting Edge Gaming: Unlocking 4K 120 FPS

We‘ve covered a ton of information about stepping up to the cutting edge of 120Hz gaming. Here are the key takeaways:

• 120Hz provides substantially increased smoothness and responsiveness compared to 60Hz. Input lag is reduced by nearly 50%!

• Reaching 4K 120 fps requires compatible TVs, consoles/GPUs, cables, and proper setup. Pay attention to those HDMI 2.1 ports!

• While higher than 120Hz is possible, it offers diminishing returns. 120Hz hits the sweet spot of maximum benefit.

• Both gaming monitors and the latest 4K 120Hz TVs have their own pros and cons for achieving ultra-smooth gameplay.

• Competitive gaming clearly benefits the most from 120Hz. But the difference is noticeable across all genres.

Gaming in buttery smooth 4K 120Hz is an absolute game changer compared to sluggish old 60Hz displays. Once you upgrade, you‘ll never look back!
