I am using the Teradek Spark 4k set for wireless HDMI transmission between the C200 and Atomos Ninja V. This small set works great with the C200 up to 4k25p with almost no latency. However, I could not make it work with the Canon EOS R5. I contacted Teradek support who was very helpful. It looks like the HDMI signal from the R5 is not recognized by the receiver. The only way I could make it work was first firing up the set with the C200, then swapping the HDMI cable from the transmitter to the R5 (this was a tip from Teradek support). Has anybody an explanation or solution? Might a HDMI EDID emulator solve the problem?
