TSDisp is designed for all users of Teamspeak who want to see exactly who they are talking to at any time.
TSDisp adds the option of being able to read the screen name of the person who is speaking to you to remove any confusion in group meetings. To use it, you need Teamspeak connected, and through TSDisp simply select a channel of "vigilance". Once done, you can see the screen name of the person who is speaking. There's actually not much more to it than that.
However, by the developer's own admission, there are a few bugs with TSDisp, one of which is it doesn't always work if you switch a game or other application to full screen mode as it does not remain in the foreground like it's supposed to. It could also do with a few customization options as to the way names are displayed - a few ways of changing the colour at the very least.
TSDisp is a handy plugin for Teamspeak users who want to know exactly who they're talking to or who deal with big online meetings.
