Multiple Reddit threads highlight random Joy-Con disconnections occurring every few minutes. Our tech editor Bo Moore encountered this problem immediately after setting up his new Switch 2, with controllers losing connection every few seconds.

While this might seem obvious, many users kept their original Switch HDMI cables, assuming compatibility. The crucial difference lies in cable specifications - the Switch 2 requires Ultra High Speed HDMI, while the original Switch's standard HDMI cable falls short. Any certified Ultra High Speed HDMI cable should work as an alternative.

Our testing confirms this solution works, mirroring numerous online reports. Nintendo officially recommends using Ultra High Speed HDMI cables for optimal docked performance.

The company states:

Confirm that you're using an "Ultra High Speed" HDMI cable to connect the dock to the TV. If it's not Ultra High Speed, your console won't perform as expected when docked.

While using included accessories is generally recommended, this serves as an important reminder about the Switch 2's specific HDMI requirements for stable Joy-Con connectivity.
