TightProjectorPro

If you want to share your computer's screen with other computers that are connected to the same Local Area Network (LAN), you should understand that attempting to do so without specialized third-party software solutions might prove to be pointless.
One of the applications that can come in handy in the situation depicted above is TightProjectorPro, as it provides you with several tools that are relevant to your current needs.

Broadcast your screen on the network

You can turn to this application if you need to broadcast the contents of your screen within your Local Area Network so that other computers can view them.
The data is streamed continuously, in a similar manner to how a projector functions. You plug it in and the contents of your screen are displayed on an external source, in this case, other PCs from your network.

Subtle interface

TightProjectorPro comes with a subtle user interface that tries to interfere with other active applications as little as possible by minimizing itself to the System Tray and running from there.
You can access its functions by right-clicking the tray icon and choosing the feature you want to access from the context menu. Alternatively, you can double-click the icon if you want to start the broadcast immediately.

Encompasses several components

This application comes with multiple components, each playing its role in helping you broadcast your screen as quickly and efficiently as possible.
First of all, TightProjectorPro is one of the core components, since it holds the ability to broadcast the contents of your screen (audio can be toggled), save the session on your computer and play it later if you want. The TightReceiver, as its name suggests, can pick these streams from your network and display them on your computer.
Last, but not least, the TightInformerPro utility enables you to send simple text messages over the network and displays them on the receiving computers as tickers.

Handy screen broadcast toolbox

All things considered, TightProjectorPro is a toolbox that contains numerous utilities, which can help you broadcast the contents of your screen, along with audio, to other computers on your network.
