Several Nintendo Switch 2 owners have reported recurring disconnections with their Joy-Con controllers. Fortunately, there's a straightforward solution: simply use the official Nintendo Switch 2 HDMI cable.

This issue has been highlighted in numerous Reddit discussions where users describe their Joy-Cons disconnecting at random intervals, sometimes every few minutes. Our technology editor, Bo Moore, also encountered this problem immediately after unboxing and setting up his new Nintendo Switch 2, experiencing frequent disconnections every few seconds.

However, the fix appears to be simple: use the HDMI cable that comes with the Nintendo Switch 2, instead of any other HDMI cable you might have on hand.

Though it may seem obvious to some, many users appear to be unplugging their original Nintendo Switch systems from their TVs without swapping the cables, assuming the old ones would suffice. While using a Nintendo Switch 1 HDMI cable with the Switch 2 seems logical, it leads to problems because the original Switch cable is not an "Ultra High Speed" HDMI cable—unlike the one provided with the Switch 2. So, if you prefer not to use the included cable, make sure to use any other certified Ultra High Speed HDMI cable instead.

Our tech editor confirmed that switching to the new Nintendo Switch 2 HDMI cable resolved the issue, as it has for many other users online.

Nintendo also advises the same through its official support site:

Make sure you are using an "Ultra High Speed" HDMI cable to connect the dock to your TV. If the cable is not Ultra High Speed, your console may not perform correctly while docked.

It's generally recommended to use the cables and accessories that come with any tech device. That said, this serves as a helpful reminder that if you ever need to replace the Nintendo Switch 2 HDMI cable, you'll require a specific type to ensure your Joy-Con controllers work properly.
