ScreenFreeze

ScreenFreeze gives you full control over your extended display, whether it's a projector, a second monitor or an LED wall. Switch content with the numeric keypad (CTRL+Num) or a clear control window with thumbnails. It works in two independent layers: the top layer covers even a running PowerPoint presentation, the bottom one appears the moment the presentation ends or crashes. The "Freeze" function instantly snapshots the current image with a single keystroke — a perfect rescue when you need to cover the screen. Show almost anything: images, videos, web pages — even with live polls, YouTube in top quality, network streams (RTSP/RTMP) and NDI. ScreenFreeze can not only receive NDI but also send it — each display as a separate source on the network. Ideal for presentations, conferences, events, churches, theatres, AV production and digital signage.
