HDMI 2.0 vs 2.1 for Consoles: What You Need
Short answer: HDMI 2.1 offers higher bandwidth than HDMI 2.0, which allows for higher resolutions and refresh rates, such as 4K at 120Hz, when both the console and TV support it. HDMI 2.0 can handle 4K at lower refresh rates, typically 60Hz. Check your console's stated specs and your TV's HDMI ports to see which version you need. For most setups, HDMI 2.1 is future-friendly, but HDMI 2.0 is fine for standard 4K gaming.
What HDMI versions mean for consoles
HDMI is the cable and port standard that carries video and audio from a console to a TV or monitor. The version number, such as 2.0 or 2.1, tells you the maximum data capacity, called bandwidth, that the connection can handle. Higher bandwidth allows more information to pass through, which supports higher resolutions and refresh rates. For a clear guide on choosing a console, see the best gaming consoles.
When you see a console listing, the HDMI version is not always stated. The maker's page may mention capabilities like 4K or 120 frames per second, which depend on the HDMI version. For example, the Xbox Series X page states "True 4K Gaming" and "Up to 120 FPS," which are features that typically require HDMI 2.1. The Nintendo Switch 2 page mentions "up to 4K resolution" and "frame rates up to 120 fps," also pointing to HDMI 2.1 support.
This article explains the difference between HDMI 2.0 and 2.1 in plain terms, so you can decide which console and TV combination fits your needs. The focus is on bandwidth, resolution, and refresh rate, not on specific game performance.
Bandwidth: the core difference
Bandwidth is the amount of data that can be transferred per second. HDMI 2.0 supports up to 18 gigabits per second, while HDMI 2.1 supports up to 48 gigabits per second. This higher bandwidth is what allows HDMI 2.1 to carry more visual information, such as higher resolutions at higher refresh rates.
In practical terms, more bandwidth means the cable can handle larger data loads without compression. For a console, this translates to the ability to output 4K at 120Hz, which requires more data than 4K at 60Hz. HDMI 2.0 can handle 4K at 60Hz, which is sufficient for standard 4K gaming.
The exact bandwidth numbers are not listed on the console maker pages provided, but the capabilities they mention, like 4K or 120 FPS, are tied to these bandwidth limits. When comparing consoles, look for stated features like "4K" or "120 FPS" to infer the HDMI version, or check the technical specs on the maker's site.

Resolution and refresh rate support
Resolution refers to the number of pixels on the screen, such as 1080p, 1440p, or 4K. Refresh rate is how many times the image updates per second, measured in hertz (Hz). A 60Hz display updates 60 times per second, while 120Hz updates 120 times.
HDMI 2.0 supports up to 4K resolution at 60Hz. This is the standard for many TVs and consoles, and it delivers a clear, smooth picture for most gaming. HDMI 2.1 supports higher combinations, such as 4K at 120Hz, which is beneficial for fast-paced games that can run at higher frame rates. Learn more about 4K gaming and 120Hz.
The Xbox Series X page states "True 4K Gaming" and "Up to 120 FPS," indicating support for 4K at 120Hz, which requires HDMI 2.1. The Nintendo Switch 2 page mentions "up to 4K resolution" and "frame rates up to 120 fps," but notes that 4K output is fixed to 60 fps. This shows that even with HDMI 2.1, the actual output depends on the console's design and the game.
When choosing a console, consider your TV's capabilities. If your TV only supports HDMI 2.0, you won't get 4K at 120Hz, even if the console supports it. Check your TV's HDMI ports and manual to see which version they support. For matching your console to your TV, see this TV resolution matching guide.
How to check your TV's HDMI version
To know if your TV can take advantage of HDMI 2.1 features, look at the HDMI ports on the back. They are often labeled with the version number, but not always. Check the TV's manual or the manufacturer's website for the specifications.
If your TV has HDMI 2.0, you can still use a console that supports HDMI 2.1, but you'll be limited to the TV's maximum capabilities, such as 4K at 60Hz. This is fine for most gaming, but you won't get the higher refresh rates.
For a new console purchase, consider whether you plan to upgrade your TV in the future. If so, a console with HDMI 2.1 support is a good choice, as it will be ready for a newer TV. If you're keeping your current TV, HDMI 2.0 may be sufficient. Also, check the TV input lag to ensure a responsive experience.
Remember, the HDMI cable also matters. To get HDMI 2.1 features, you need a cable that supports the higher bandwidth, often labeled as "Ultra High Speed." The console may come with a compatible cable, but check the box contents.
What to pick for your situation
The right choice depends on your TV, your budget, and how you plan to use the console. If you have a 4K TV with HDMI 2.1 and want the highest refresh rates, look for a console that supports those features. If you have an older TV or are on a budget, a console with HDMI 2.0 support may be enough.
For handheld consoles, HDMI output is less critical because you play on the built-in screen. However, if you plan to connect to a TV, check the HDMI version for external display support. The Nintendo Switch 2, for example, supports 4K when docked, which requires HDMI 2.1.
Use the guides on this site to compare consoles based on stated details like storage and edition. The HDMI version is often implied by the features listed, so read the maker's pages for clarity. For top picks, see the best Xbox consoles and best PlayStation consoles.
