Lets folks who design video walls use Blu-ray or HD Satellite sources.
I hate HDMI and HDCP. They are supposedly “intelligent” signals. When you plug them in, they look at what they’re being plugged into and decide whether they like it or not. If they don’t like what they see, they won’t pass the signal through. I eventually got so fed up trying to split HDMI signals from DSLR’s for monitoring, that I just gave up and bought a device that converts them to HD-SDI and called it a day. Other times you’ll plug in 5 different HDMI cables that don’t work, and the 6th one will. Until you try it later and it stops working too. I hate HDMI and HDCP.
