The pursuit of smoother visuals and more responsive gameplay is a constant for gamers and professionals alike. A key component in achieving this is a high refresh rate display, often measured in frames per second (fps). While monitors and graphics cards are crucial, the connection between them, namely the HDMI cable, plays a vital role. This leads to a common and important question: Can you get 120fps with HDMI? The answer is a resounding yes, but it comes with important caveats and requires understanding the specific HDMI version, the capabilities of your hardware, and the resolution you’re aiming for.
Understanding the Fundamentals: Refresh Rate and Bandwidth
Before diving into the specifics of HDMI and 120fps, it’s essential to grasp the core concepts.
What is Refresh Rate?
Refresh rate, measured in Hertz (Hz), indicates how many times per second a display updates its image. A 60Hz monitor refreshes 60 times per second, displaying 60 unique images. A 120Hz monitor, on the other hand, refreshes 120 times per second, theoretically allowing for 120 unique images per second. This translates to smoother motion, reduced blur, and a more immersive experience, especially in fast-paced games or dynamic video content.
What is FPS?
Frames per second (fps) represents the number of individual frames your graphics processing unit (GPU) can render and send to the display each second. Higher FPS generally means a smoother and more fluid visual experience. When your FPS matches or exceeds your display’s refresh rate, you’re getting the most out of your hardware.
The Role of Bandwidth
The critical factor linking your GPU, your display, and the desired refresh rate is bandwidth. Bandwidth is essentially the data carrying capacity of a connection. Think of it as a highway: the wider the highway (higher bandwidth), the more cars (data) can travel at the same time. To transmit a 120fps signal, especially at higher resolutions, a significant amount of data needs to be transferred per second. HDMI cables, through their various versions, offer different levels of bandwidth.
HDMI Versions and Their Capabilities for 120fps
HDMI (High-Definition Multimedia Interface) is the industry standard for transmitting digital audio and video signals. Over the years, HDMI has evolved, with each new version offering increased bandwidth and support for new features. The ability to achieve 120fps with HDMI is directly tied to the version of the HDMI standard being used.
HDMI 1.4: A Glimpse of Possibilities
HDMI 1.4, introduced in 2009, offered a significant leap in bandwidth compared to its predecessors. While it was a major improvement, its bandwidth capabilities are somewhat limited for high-refresh-rate, high-resolution content.
- Bandwidth: Approximately 10.2 Gbps.
- 120fps Support: HDMI 1.4 can support 120fps, but typically only at lower resolutions. For example, it can handle 1080p resolution at 120Hz. At 4K resolution, the maximum it can manage is usually 30Hz or 40Hz, making 120fps at 4K impossible with this version.
HDMI 2.0: The Gateway to Higher Refresh Rates
HDMI 2.0, released in 2013, marked a substantial upgrade, significantly increasing bandwidth and enabling higher resolutions and refresh rates. This version opened the door for many users to experience 120fps gaming.
- Bandwidth: Approximately 18 Gbps.
- 120fps Support: HDMI 2.0 is capable of supporting 120fps at 1080p and, crucially, at 4K resolution. However, there’s a limitation: at 4K resolution, the maximum refresh rate achievable with HDMI 2.0 while maintaining full color depth and without chroma subsampling (which can reduce color quality) is often 60Hz. To achieve 4K 120Hz, you would typically need chroma subsampling or a reduced color format, which might not be ideal for all users. Nevertheless, for 1080p and 1440p, 120fps is readily achievable with HDMI 2.0.
HDMI 2.1: The Current Standard for High Refresh Rates
HDMI 2.1, released in 2017, is the current pinnacle of HDMI technology, designed specifically to cater to the demands of next-generation gaming consoles, high-resolution displays, and ultra-high refresh rates. This version is the key to unlocking 120fps at higher resolutions without significant compromises.
- Bandwidth: A massive 48 Gbps.
- 120fps Support: HDMI 2.1 is engineered to handle 120fps at 4K resolution with full RGB color and without any chroma subsampling. Furthermore, it can even support 8K resolution at 60fps and 10K resolution at 120fps (though displays and hardware for these are still emerging). This makes HDMI 2.1 the definitive standard for anyone aiming to experience 120fps at 4K or even higher resolutions.
Hardware Requirements for 120fps via HDMI
Achieving 120fps isn’t solely dependent on the HDMI cable or port. Your entire setup needs to be capable of delivering and displaying this performance.
Graphics Card (GPU)
Your GPU is the engine that drives your frame rates. To consistently hit 120fps, you need a graphics card powerful enough to render the game or application at that frame rate at your desired resolution and graphical settings.
- Mid-Range to High-End GPUs: Generally, GPUs from the last few generations (e.g., NVIDIA GeForce RTX 30-series and 40-series, AMD Radeon RX 6000-series and 7000-series) are capable of pushing 120fps in many modern titles at 1080p and 1440p. For 4K 120fps, you’ll typically need a top-tier GPU.
- Driver Updates: Always ensure your GPU drivers are up to date. Manufacturers frequently release driver updates that optimize performance for new games and improve overall stability.
Display (Monitor or TV)
Your display must have a native refresh rate of at least 120Hz to take advantage of 120fps output.
- Native Refresh Rate: A 120Hz or higher native refresh rate is essential. While some displays can upscale to higher refresh rates, native support is always preferred for the best experience.
- HDMI Port Version: Your display must also feature an HDMI port that supports the required HDMI version (at least HDMI 2.0 for 4K 60Hz/1080p 120Hz, and ideally HDMI 2.1 for 4K 120Hz).
Source Device (PC, Gaming Console)
The device generating the signal also needs to be capable.
- PC: Your PC’s motherboard must have an HDMI port that supports the necessary HDMI version. More importantly, your GPU’s output ports will determine the HDMI version you can utilize.
- Gaming Consoles:
- PlayStation 5 (PS5): Supports HDMI 2.1, allowing for 4K 120fps gaming in compatible titles.
- Xbox Series X/S: Also supports HDMI 2.1, enabling 4K 120fps gaming where supported.
- Older Consoles: Previous generations of consoles (e.g., PS4, Xbox One) typically do not support the HDMI versions required for 4K 120fps.
The HDMI Cable: A Crucial Link in the Chain
It’s not enough to have HDMI 2.1 ports on your devices; you also need an HDMI cable that can handle the increased bandwidth of HDMI 2.1.
HDMI Cable Certifications
HDMI cables are certified based on their capabilities. Using an older or uncertified cable can bottleneck your performance and prevent you from reaching 120fps, even if your devices support it.
- High-Speed HDMI Cable: Generally supports HDMI 1.4 capabilities, sufficient for 1080p 120Hz.
- Premium High-Speed HDMI Cable: Designed to support HDMI 2.0 features and bandwidth (18 Gbps). This is suitable for 4K 60Hz and 1080p/1440p 120Hz.
- Ultra High-Speed HDMI Cable: This is the certification required for HDMI 2.1 and its full 48 Gbps bandwidth. These cables are essential for reliably achieving 4K 120fps and beyond. Ensure the cable is explicitly labeled as “Ultra High-Speed HDMI Cable” or “HDMI 2.1 Certified.”
Cable Length and Quality
While cable length generally doesn’t impact digital signal integrity as much as analog signals, very long or poor-quality cables can still introduce issues, especially with the high bandwidth demands of HDMI 2.1. For the best results, use certified cables of appropriate length for your setup.
Troubleshooting and Optimizing for 120fps
Even with the right hardware, you might encounter issues. Here’s how to troubleshoot and ensure you’re getting the best performance.
Confirming Settings
Double-check all your settings on both your PC/console and your display.
- Display Settings: Ensure your monitor/TV is set to its native 120Hz refresh rate. Sometimes, displays are factory-set to 60Hz, and you need to manually change this in the display’s on-screen menu or through your operating system’s display settings.
- Graphics Settings (PC): In your graphics card control panel (NVIDIA Control Panel or AMD Radeon Software) and in-game settings, verify that the resolution and refresh rate are correctly configured.
- Console Settings: On PS5 and Xbox Series X/S, navigate to the video output settings and confirm the resolution and refresh rate are set to your desired levels.
Game-Specific Settings
Not all games support 120fps, or they might require specific graphics settings to be lowered to achieve it.
- Performance Modes: Many modern games offer different graphics modes. Look for a “Performance Mode” or similar setting, which often prioritizes frame rate over graphical fidelity, making 120fps more achievable.
- Resolution Scaling: Some games allow for dynamic resolution scaling, which can lower the rendering resolution on the fly to maintain a higher frame rate. This can be a good compromise if your hardware struggles to hit 120fps at native resolution.
Testing Your Connection
- Built-in Benchmarks: Many games include built-in benchmarking tools that can show your average FPS.
- FPS Monitoring Software: Tools like MSI Afterburner, NVIDIA GeForce Experience overlay, or built-in game counters can provide real-time FPS information.
- Display’s On-Screen Information: Many modern displays can show the current resolution and refresh rate being received, which is a quick way to confirm if your 120Hz signal is being registered.
Beyond Gaming: Applications for 120fps HDMI
While gaming is the most common driver for 120fps, other applications can also benefit.
- Video Editing: Smoother playback and scrubbing through footage, especially for content creators working with high-frame-rate footage.
- Professional Workflows: Certain professional applications, particularly those in motion graphics or simulations, can benefit from the increased fluidity offered by higher refresh rates.
- General Desktop Use: While the difference is less pronounced than in gaming, a higher refresh rate can make scrolling through web pages and interacting with your operating system feel more responsive and pleasant.

Is HDMI 2.0 capable of 120fps?
Yes, HDMI 2.0 can support 120 frames per second (fps) for gaming and other video content, but with certain limitations. Specifically, it can achieve 120fps at resolutions such as 1080p (Full HD) and 1440p (2K). When you move to higher resolutions like 4K, the bandwidth of HDMI 2.0 becomes a bottleneck.
For 4K resolution, HDMI 2.0 is typically limited to 60fps. To get 4K at 120fps, you would need a newer HDMI standard like HDMI 2.1, which offers significantly more bandwidth to handle the increased data required for these high refresh rates at higher resolutions.
What are the requirements to achieve 120fps over HDMI?
To achieve 120fps over HDMI, several components in your setup need to be compatible. Firstly, your graphics card or console must be capable of outputting a 120fps signal at the desired resolution. Secondly, your display (monitor or TV) must also support a 120Hz refresh rate. Lastly, and crucially, the HDMI cable itself needs to be certified for the appropriate HDMI standard that can carry the necessary bandwidth.
For 1080p or 1440p at 120fps, a certified High Speed HDMI cable (often marketed as HDMI 1.4 or 2.0 compatible) is usually sufficient. However, for 4K at 120fps, you absolutely need an Ultra High Speed HDMI cable, which is certified for the HDMI 2.1 standard, to ensure stable and consistent performance.
Does the HDMI cable quality matter for 120fps?
Yes, the quality and certification of your HDMI cable are paramount when aiming for 120fps, especially at higher resolutions. A poor-quality or uncertified cable may not have the necessary bandwidth to transmit the signal reliably, leading to issues like flickering, signal loss, or the inability to even achieve 120fps.
Using a cable specifically certified for the HDMI standard that supports your desired frame rate and resolution is essential. For 1080p/1440p at 120fps, a good quality High Speed cable is usually adequate, but for 4K/120fps, an Ultra High Speed HDMI cable (HDMI 2.1) is a non-negotiable requirement to handle the immense data flow.
Can all TVs and monitors display 120fps via HDMI?
No, not all TVs and monitors can display 120fps via HDMI. The display itself must have a native refresh rate of 120Hz or higher to achieve this. Many older or budget-friendly displays are limited to 60Hz or 75Hz refresh rates, meaning they cannot physically refresh the image 120 times per second, regardless of the signal they receive.
When purchasing a display for high refresh rate gaming, it’s important to check its specifications for the supported refresh rate and the specific HDMI version it uses, as this will determine if it can take advantage of 120fps signals from your gaming device.
What is the difference between 120Hz and 120fps?
While often used interchangeably in casual conversation, 120Hz and 120fps refer to different aspects of the gaming experience. 120Hz refers to the refresh rate of your display, meaning how many times per second the screen can update its image. 120fps, on the other hand, refers to the frame rate generated by your graphics card or console, which is the number of individual images your gaming hardware produces per second.
For a smooth 120fps gaming experience, both your hardware and your display must be capable of matching that rate. Your graphics card needs to render 120 frames per second, and your display needs to be able to refresh at 120Hz to show each of those frames. If one is lower than the other, you will be limited by the lower value.
Does VSync or G-Sync/FreeSync affect 120fps over HDMI?
Yes, display synchronization technologies like VSync, G-Sync, and FreeSync can affect how you perceive and achieve 120fps over HDMI, but they don’t inherently prevent it. VSync synchronizes your game’s frame rate with your display’s refresh rate to prevent screen tearing, but if your game consistently drops below 120fps, VSync might cap it lower to maintain synchronization, potentially reducing the perceived smoothness.
G-Sync and FreeSync are adaptive-sync technologies that dynamically adjust the display’s refresh rate to match the GPU’s frame rate, eliminating tearing and reducing stuttering without the input lag often associated with VSync. These technologies work very well with 120fps gaming, providing a smoother visual experience, as long as your HDMI connection and hardware support the target frame rate.
Will I notice a difference playing at 120fps over HDMI compared to 60fps?
Absolutely, the difference between 60fps and 120fps is quite noticeable and can significantly enhance your gaming experience, provided your display and HDMI connection can support it. At 120fps, motion appears much smoother and more fluid, reducing blur and making fast-paced action easier to track.
This increased smoothness translates to improved responsiveness, as there’s less delay between your input and the action on screen. For competitive gamers, the advantage of seeing enemies and reacting faster can be a significant factor in performance, making the upgrade to 120fps gaming well worth the investment in compatible hardware and cables.
