How can I determine whether a monitor has a horn in my computer?

1. First, check whether there is a paper instruction page in the display package you purchased. If so, check whether there is an introduction to audio connection on the instruction page, for example:

2. If there is no instruction page in the package, check whether there is an audio interface at the display interface on the bottom. If there is an audio port, see step 3 to determine whether there is a built-in speaker, if there is no audio port, there must be no built-in speaker, for example:

2) if the monitor has an audio interface, you can check whether the icon on the monitor is displayed as; it proves that the monitor has a built-in speaker. For details, refer:

2) if the display has an audio port and the icon marked at the audio port is:, this audio port is not a built-in audio port with a speaker, it should be a machine with a digital interface such as DP or HDMI, as shown in the following figure:

In general, we just need to check whether the monitor has an interface for receiving audio. We just need to check it carefully. This is not something we can't see, the labels are displayed on the monitor.
