The PlayStation 5 (PS5) is a powerhouse console capable of stunning visuals and incredibly smooth gameplay. To fully unlock its potential, especially the coveted 120Hz refresh rate, you need the right HDMI connection. The short answer is: while technically some lower resolutions might work with older HDMI versions, for the best, most consistent, and future-proofed experience at higher resolutions like 4K, you ideally need an HDMI 2.1 port on both your TV and your PS5, and an Ultra High Speed HDMI 2.1 cable. This is the true enabler for 4K 120Hz gaming on the PS5. Let’s delve into why this is the case, and explore the intricacies of HDMI versions and their impact on your PS5 gaming experience.
Understanding HDMI Versions: A Crucial Foundation
Before we dissect the PS5’s specific requirements, it’s important to understand what different HDMI versions offer. HDMI (High-Definition Multimedia Interface) is the standard for transmitting audio and video signals. Each iteration of HDMI brings increased bandwidth, unlocking higher resolutions, refresh rates, and advanced features.
- HDMI 1.4: This older standard can handle 4K at 30Hz, and 1080p at 120Hz theoretically. However, it lacks the bandwidth needed for consistent and reliable 4K 120Hz output. In some cases, even forcing 1080p 120Hz might not work, as the PS5 is designed with smart bandwidth detection.
- HDMI 2.0 (a/b): A significant step up, HDMI 2.0 significantly increases the bandwidth compared to 1.4. It can handle 4K at 60Hz, and 1440p or 1080p at 120Hz. While HDMI 2.0b can technically display 120Hz at lower resolutions, it falls short of the requirements for optimal PS5 performance at 4K 120Hz, especially with HDR enabled.
- HDMI 2.1: This is the gold standard for the PS5 and the future of gaming. HDMI 2.1 boasts a massive bandwidth increase compared to its predecessors, enabling 4K resolution at up to 120Hz, along with other features like Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM). This is the only version that can reliably and consistently deliver the PS5’s full potential.
Why HDMI 2.1 Matters for PS5 120Hz
The PS5 is designed to output stunning visuals at high frame rates, and HDMI 2.1 is the key to unlocking this performance. Here’s a breakdown of the benefits:
- Bandwidth: HDMI 2.1’s increased bandwidth of 48Gbps is essential for transmitting the massive amount of data required for 4K resolution at 120Hz refresh rate, especially with HDR.
- VRR (Variable Refresh Rate): VRR synchronizes the refresh rate of your display with the frame rate output of the PS5, eliminating screen tearing and stuttering for a smoother gaming experience. This is an HDMI 2.1 feature.
- ALLM (Auto Low Latency Mode): ALLM automatically switches your TV to its lowest latency mode when gaming, reducing input lag for more responsive controls. This is also an HDMI 2.1 feature.
- Future-Proofing: As game developers continue to push the boundaries of visual fidelity, HDMI 2.1 ensures your setup remains compatible with future games and updates that may require even more bandwidth.
What if I Don’t Have HDMI 2.1?
If your TV or monitor only has HDMI 2.0 or older ports, you can still play games on your PS5, but you won’t be able to experience 4K at 120Hz. You’ll be limited to either a lower resolution (like 1440p or 1080p) at 120Hz, or 4K at 60Hz. While this is still a great experience, you’ll be missing out on the visual clarity and smoothness that HDMI 2.1 provides.
Verifying Your Setup
Here’s how to confirm if your PS5 is outputting at 120Hz:
- PS5 Settings: Go to Settings > Screen and Video > Video Output > Video Output Information.
- Check the Information: Look for “120Hz” under the “Information for the connected HDMI device” header. If it’s not listed, your display doesn’t support 120Hz, or the setting isn’t properly enabled.
- Enable 120Hz Output: In Settings > Screen and Video > Video Output, make sure “Enable 120Hz Output” is set to “Automatic.”
Choosing the Right Cable
Even if your TV and PS5 support HDMI 2.1, you need an Ultra High Speed HDMI cable certified to handle the 48Gbps bandwidth. Standard or High Speed HDMI cables may not be sufficient, leading to signal dropouts or reduced performance. The PS5 ships with an HDMI 2.1 cable, so if you have that cable, be sure to use it.
Conclusion
While the PS5 can technically connect to displays using older HDMI standards, to truly unleash its potential for 4K 120Hz gaming – including features like VRR and ALLM – an HDMI 2.1 port on your TV (and PS5) along with an Ultra High Speed HDMI 2.1 cable are essential. By investing in the right equipment, you’ll be well-equipped to experience the future of gaming.

Frequently Asked Questions (FAQs)
Here are some frequently asked questions to further clarify HDMI requirements for 120Hz gaming on the PS5:
1. Does HDMI 1.4 support 120Hz on PS5?
Theoretically, HDMI 1.4 can support 1080p at 120Hz. However, the PS5 may not allow this, limiting you to 60Hz due to bandwidth limitations and the console’s smart detection features. HDMI 1.4 is not suitable for 4K 120Hz gaming.
2. Can HDMI 2.0b do 120Hz on PS5?
HDMI 2.0b can support 120Hz at lower resolutions like 1440p or 1080p. However, it lacks the bandwidth for reliable 4K 120Hz, especially with HDR enabled.
3. Is HDMI 1.4 better than 2.0 for PS5 gaming?
HDMI 2.0 is significantly better than HDMI 1.4 for PS5 gaming. It offers increased bandwidth, supporting 4K at 60Hz, whereas HDMI 1.4 is limited to 4K at 30Hz.
4. Do I need HDMI 2.1 for 120Hz PS5?
Yes, to get the best experience, it is better to have HDMI 2.1 for 4K at 120Hz on the PS5. While you might get 120Hz at lower resolutions with older HDMI versions, HDMI 2.1 is required for the highest fidelity visuals.
5. Is HDMI 1.4 good enough for PS5?
