In 12g UHD mode, are there any registers to be configured? I searched the forum. Many people reported that there was a problem in 12g mode. Is there any way to deal with it?

The test cable I used is a 12g cable from canare, with a length of 3M. Is it because the minimum value of adaptive equalization is too large for a 3M long cable? Is it necessary to reduce the threshold of adaptive equalization?
