The HDMI ports labeled "STB" and "ARC" on your TV have specific functions. Let's break down what each label means and whether it matters which one you connect your Nintendo Switch to.

1. STB (Set Top Box):

   • The STB label on an HDMI port indicates that it is specifically designed for connecting devices like cable or satellite set-top boxes [1].
   • However, it's important to note that the STB label does not limit the port's functionality to only set-top boxes. You can connect other devices, such as gaming consoles, to this port as well [2].
   • If you connect your Nintendo Switch to an HDMI port labeled STB, it should work just fine.

2. ARC (Audio Return Channel):

   • The ARC label on an HDMI port indicates that it supports the Audio Return Channel feature [1].
   • The Audio Return Channel allows audio to be sent from your TV to a compatible audio device, such as a soundbar or home theater system, through the HDMI cable [2].
   • If you have a soundbar or home theater system that supports ARC, connecting it to the HDMI port labeled ARC will allow you to control the TV's audio using the device-specific remote control [2].
   • If you don't have a soundbar or home theater system with ARC support, you can connect your Nintendo Switch to any other HDMI port on your TV.

In summary, the STB and ARC labels on your TV's HDMI ports indicate their specific functions, but they do not limit the ports to only those devices. You can connect your Nintendo Switch to any HDMI port on your TV, including the one labeled STB, without any issues.
