Does Xbox Series X and S Have HDMI 2.1 Ports?

Both the Xbox Series X and Xbox Series S come equipped with HDMI 2.1 ports, enabling next-generation gaming features for compatible displays. This article confirms the presence of this connectivity standard on both consoles, details the performance benefits like 120Hz refresh rates and Variable Refresh Rate, and highlights the subtle differences in how each machine utilizes the bandwidth for resolution and output.

Confirming HDMI 2.1 Connectivity

Microsoft ensured that both consoles in their ninth-generation lineup support the latest connectivity standard. Whether you purchase the flagship Xbox Series X or the digital-only Xbox Series S, you will find an Ultra High Speed HDMI port on the back of the device. This inclusion guarantees that both systems are future-proofed for modern televisions and monitors that support higher bandwidths.

Performance Benefits for Gamers

The presence of HDMI 2.1 unlocks several key features that enhance gameplay smoothness and visual fidelity. Both consoles support 4K resolution at up to 120 frames per second, provided the game is optimized and the display supports it. Additionally, the port enables Variable Refresh Rate (VRR) to eliminate screen tearing and Auto Low Latency Mode (ALLM) to automatically switch the TV to game mode for reduced input lag. These technologies work seamlessly on both the Series X and Series S hardware.

Differences in Output Capabilities

While both consoles have the port, their graphical power dictates how they utilize it. The Xbox Series X is designed to render games at native 4K resolution, fully leveraging the HDMI 2.1 bandwidth for high-fidelity output. The Xbox Series S typically targets 1440p resolution at 120Hz but can upscale to 4K output for media and compatible games. Despite this difference in rendering power, the physical HDMI 2.1 interface remains consistent across both devices, ensuring compatibility with the same range of high-performance displays.

Requirements for Full Functionality

To experience the full benefits of the HDMI 2.1 port on either console, users must connect the system to a compatible TV or monitor using the included Ultra High Speed HDMI cable. Older HDMI cables or displays limited to HDMI 2.0 may restrict performance to 60Hz at 4K or lower resolutions. Ensuring your display ecosystem matches the console’s capabilities is essential to taking full advantage of the high refresh rates and advanced features provided by the hardware.
