For Xbox Series S owners looking to squeeze every last frame out of their hardware, the question of high refresh rates is critical. The short answer to whether the console supports 120Hz is a definitive yes, but the reality lies in the specifics of your setup. Understanding the distinction between the console’s output and the requirements of your display is the key to unlocking a smoother gaming experience.
Native Resolution vs. Refresh Rate
When discussing 120Hz, it is essential to separate the concept of resolution from refresh rate. The Xbox Series S is capable of rendering games at 4K resolution, but achieving a stable 120 frames per second (FPS) at that resolution is often demanding. The console supports 120Hz output, but you may need to adjust your visual settings to prioritize performance. This typically means selecting a lower resolution, such as 1080p, to maintain the high frame rate without overloading the GPU.
HDMI Requirements and Bandwidth
Not all cables and ports are created equal, and this is the most common reason a 120Hz setup fails. To transmit a 120Hz signal, you must use a High-Speed HDMI 2.1 cable. Older standard HDMI cables or cables that are not explicitly rated for high bandwidth will choke the data flow, resulting in the display defaulting to 60Hz. Furthermore, the HDMI port on your TV must also be 2.1 compliant; using a port labeled 1.4 or older will prevent the high refresh rate from working.
Checklist for a 120Hz Setup
Xbox Series S firmware updated to the latest version.
High-Speed HDMI 2.1 cable.
TV with an HDMI 2.1 port.
TV settings configured to allow variable refresh rate (VRR).
Television Settings Matter
Even with the correct cable and port, the television itself must be configured correctly. You need to ensure the specific HDMI input is set to handle 4K at 120Hz, which is often buried in the TV’s picture settings menu. Additionally, features like Black Frame Insertion (BFI) or motion smoothing might interact poorly with the high refresh rate, causing visual artifacts. Disabling these post-processing features often results in a cleaner image.
Performance Benefits and Limitations
Running at 120Hz provides a tangible benefit in competitive gaming. The reduced motion blur and lower input latency make aiming and movement feel significantly more responsive. However, developers optimize for either 4K or 120Hz, not both simultaneously on the Series S. If you enable 120Hz mode, you might notice a drop in visual fidelity, such as reduced draw distance or lower texture quality. The goal is to find the right balance between smoothness and graphical detail that suits your preference.
Compatibility with Monitors
While TVs are the standard display for Xbox consoles, some enthusiasts prefer using a high-end monitor. Monitors often have faster pixel response times, making them ideal for competitive play. If you are using a DisplayPort connection, ensure the monitor supports DisplayPort 1.4 or higher. The bandwidth capabilities of DisplayPort make achieving 120Hz at 4K much more reliable than HDMI in some scenarios.
Future-Proofing Your Setup
The Xbox Series S was built with next-gen standards in mind, including HDMI 2.1 and full 120Hz support. As game engines become more efficient, titles that currently require performance mode will likely be able to run at 4K 120Hz without compromise. Investing in the correct hardware now ensures your setup will be ready to handle future titles and free updates that take advantage of the full potential of the hardware.
