Many users, unaware, reuse cables from the original Nintendo Switch, assuming compatibility. However, the Nintendo Switch 1’s HDMI cable isn’t "Ultra High Speed," unlike the Nintendo Switch 2’s cable. If you prefer not to use the included cable, any Ultra High Speed HDMI cable should work.

Using the provided cables is generally wise for any tech device. If you need to replace the Nintendo Switch 2 HDMI cable, ensure it’s Ultra High Speed to maintain Joy-Con functionality.
