What Type of HDMI Cable Comes With Xbox Series X?

The Xbox Series X ships with a specific high-performance cable designed to unlock the console’s full visual potential. This guide confirms the exact HDMI standard included in the box, explains the benefits of Ultra High Speed connectivity for 4K and 120Hz gaming, and helps you determine if your current display setup requires a replacement cable.

The Included Cable Specification

Microsoft includes an Ultra High Speed HDMI cable in the Xbox Series X packaging. This cable meets the HDMI 2.1 specification, which is a significant upgrade over the HDMI 2.0 cables commonly found with previous generation consoles. The primary purpose of this inclusion is to ensure that users can immediately access the highest fidelity features the hardware supports without needing to purchase third-party accessories separately.

Why HDMI 2.1 Matters for Gaming

The HDMI 2.1 standard provides the necessary bandwidth to support resolutions up to 8K at 60Hz and 4K at 120Hz. For the Xbox Series X, the most relevant benefit is the ability to output 4K resolution at 120 frames per second on compatible displays. Older HDMI cables often lack the bandwidth required for this data throughput, which can result in the console defaulting to lower resolutions or refresh rates.

In addition to raw resolution and frame rates, the Ultra High Speed cable supports advanced gaming features such as Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM). VRR synchronizes the display’s refresh rate with the console’s output to eliminate screen tearing, while ALLM automatically switches the TV to game mode to reduce input lag. These features rely on the data capacity provided by the HDMI 2.1 standard included with the system.

Compatibility with Older Displays

While the included cable is optimized for modern TVs, it is fully backwards compatible with older displays that use HDMI 2.0 or HDMI 1.4 ports. You can safely use the Xbox Series X cable with an older television, but the console will not be able to output 4K at 120Hz on those screens. The system will automatically negotiate the best possible signal based on the capabilities of the connected display, ensuring functionality even without a new TV.

When to Purchase a Replacement

For most users, the cable provided in the box is sufficient for all needs. However, you may need to purchase a replacement Ultra High Speed HDMI cable if the included one is too short for your entertainment center setup or if it becomes damaged. When buying a spare, look for certification labels that confirm the cable supports 48Gbps bandwidth to ensure you maintain access to 120Hz gaming and other high-end features.
