Any actions you perform on your Mac will be mirrored or extended to the TV screen, depending on your chosen display settings.
If you are using a different input method, such as a game console or set-top box, and want to use your Mac’s keyboard and mouse with them, this typically wouldn’t work unless the device explicitly supports such an option. In general, for a straightforward laptop to TV connection, your existing peripherals will function as usual.
Is the audio transmitted through the USB connection when connecting to a TV?
Yes, when you connect your Mac to a TV using a USB to HDMI adapter, both video and audio signals can be transmitted through the HDMI connection. This means you should hear sound through your TV’s speakers without needing to make additional adjustments. Upon connecting, your Mac should automatically switch the audio output to the TV.
If you do not hear sound coming from the TV, you may need to check your Mac’s sound settings. Go to System Preferences, select “Sound,” and check the output section to ensure that the TV is listed as the selected audio output device. If it is not selected, you can easily change it to route audio through the TV.
Can I disconnect my Mac from the TV at any time?
Yes, you can disconnect your Mac from the TV at any time without any issues. It’s always a good practice to properly disconnect the display before unplugging the adapter or cables. You can do this by going to System Preferences, clicking on “Displays,” and then either selecting “Detect Displays” or choosing to “Turn off” the external display to avoid any potential issues.
Once you have safely disconnected the display, you can simply unplug the USB to HDMI adapter from your Mac and then from the TV. This ensures that both devices are aware of the change and prevents any potential disruptions or glitches in future connections.
