People often get confused between the utility of an HDMI adapter and an HDMI splitter.

The conditions that need to be checked before you set up to make the connections are:

  • The system to which an external or a second monitor is to be attached needs to have the function of supporting multiple displays. The connection will not be initiated until your system has this feature of multiple connections.
  • Also, make sure that your system supports an HDMI port connection. Many systems nowadays support other formats also like VGA, DVI and etc. So, if you buy the HDMI kit to set up the connection and later on you find that your system does not support it then it might be a little disappointing. So, to avoid this problem check your system properly before initiating the connection.
