My cameraman uses a Canon DSLR camera where, when the HDMI output is enabled, the viewfinder shuts off (Canon 6D Mark II). I am wondering if I can use an HDMI splitter before my capture card (Magewell HDMI/USB C) so I can run the second HDMI output to a video monitor? Will a splitter degrade the signal? Will it add more latency? Which one should I buy?
