Hello Hakan -<br><br>PJLink is a standard for controlling remote display devices; as such it only defines controls for power on/off, shutter, volume/microphone volume, and video input source selection (hardware input). PJLink does not specify how to share your screen via the network.<br><br>Looking at the InFocus projector, it looks like it's using a version of the Miracast technology for sharing your computer screen via the network. Video sharing via network is not a PJLink option since the PJLink standard does not define screen sharing, only basic remote projector control.<br><br>OpenLP is designed to share the screen via a second monitor (in other words, a second video card in your computer) only.<br>
