For Xbox Series S owners looking to squeeze every last frame out of their hardware, the question of high refresh rates is a critical one. The promise of buttery-smooth gameplay and a competitive edge in fast-paced shooters is incredibly tempting, leading many to ask: does Xbox Series S support 120Hz?
Understanding HDMI Bandwidth and Refresh Rates
The foundation of any high refresh rate experience lies in the HDMI connection between your console and display. To output a 120Hz signal, especially at higher resolutions, the cable and port must support specific bandwidth standards. Xbox Series S utilizes HDMI 2.1, which is the standard required for uncompressed 4K at 120 frames per second. If your television or monitor does not also have an HDMI 2.1 port and support HDR, you will be unable to achieve the full 120Hz benefit, regardless of what the console is capable of.
Native Performance Targets vs. Dynamic Resolution
Unlike its more powerful sibling, the Xbox Series X, the Series S does not have the raw graphical horsepower to render many modern games at a native 4K resolution running at 120 frames per second. Instead, developers often target a dynamic or checkerboard 1440p resolution to maintain high frame rates. For the majority of titles, the Series S will output a 1440p image and then use a process known as checkerboard rendering to upscale it to 4K, allowing it to consistently hit 60fps or, in performance modes, 120fps without a significant drop in visual fidelity.
The Reality of 120Hz Support in Games
Support for 120Hz is not a universal setting that can be toggled on or off; it must be implemented by the game's developer. When a game on Xbox Series S supports 120fps, it usually offers a "Performance" mode that prioritizes frame rate over resolution. This mode is where you will see the benefits of 120Hz, providing incredibly snappy response times that are particularly noticeable in competitive multiplayer titles like shooters and racing games. If the game is locked to 30fps or 60fps, the high refresh rate monitor will simply display the frames as they are delivered, without magically creating new ones.
Setting Up Your Console for High Refresh Rates
Enabling the technology is a straightforward process, but it requires attention to detail in the settings menu. To ensure your Xbox Series S is pushing out 120Hz, you must configure both the console and the display correctly. The display must be recognized by the console as a 120Hz capable screen. If the TV only reports 60Hz capabilities, the console will not offer 120Hz as an option, even if the port is technically HDMI 2.1.
Steps to Enable 120Hz on Xbox Series S
Navigate to the Xbox Settings menu, then go to Display and visuals.
Select Video output and ensure the HDMI signal format is set to Enhanced.
Go back to Display and visuals, then choose TV settings.
Verify the TV resolution matches the setting found under "Current display mode," confirming the TV is communicating at the correct frequency.
The Benefits Beyond Resolution
While the visual difference between 60Hz and 120Hz can be subtle in slower-paced games, the advantages become stark in high-velocity environments. A 120Hz display reduces motion blur and ghosting, making it easier to track fast-moving objects. Furthermore, the reduced input latency provides a tangible competitive advantage, allowing player reactions to register on screen almost instantaneously. This makes the feature not just a visual upgrade, but a functional one for serious gamers.
