Kosin store tv projector

This is my Barco Graphics 801 CRT projector. In the first part of the video, the input is a standard interlaced video signal (576i). When I switch to the other channel, the projector is driven by my MacBook. The signal is 1920 x 1080 @ 60Hz (1080 progressive). In the 576i signal, the scan-lines are visible!!! If my camera was better, you could see it in the video. The projector is from 1994 but it still delivers an amazing image! The Barco has a very short runtime, only 827 hours.
