What is the best KVM Switch for me and what factors do I need to take into account when choosing?

It's important to carefully consider what is the best KVM switch for your configuration depending on your application requirements and the switch features. In order to find the best KVM switch for your configuration here are the major questions to consider:

1.Existing PC Setup - Purchase a KVM switch that supports the number of computers in your setup.

2.Required Video Formats - It is best practice to use the same video connections wherever possible.

3.Multiple monitor support? Ensure every computer can support the number of monitors you are looking to use in your setup. This is 4 computers 2 monitors KVM switch (HDMI + HDMI).

4.Hotkey support- TESmart KVM switches support the use of hotkey combinations to complete tasks such as switching between computers.

How can I get the sound from L/R?

1. Please confirm what output interface is the computer equipped with? (DVI? HDMI?) If your computer is equipped with DVI output, normally that the DVI output does not carry audio signals, so the audio signal cannot be output to the speaker.

2. After you connect the headset, you need to switch to the computer ith the audio device turned on. Only the computer that controls the audio playback will output audio.

3. If you have controlled the computer to turn on the audio device, select the correct audio output channel. (Right-click the speaker, open the sound settings, select the correct HDMI output device, and set it as default.)
