Thanks, @wendell I finally caved and purchased a fibbr cable. I went from a maximum length of: TB3 dock - 6.56’ club3d dp1.4 → KVM - 6.56’ club3d dp1.4 → 1440p@165hz monitor ~ 13.12’ total to now: TB3 dock - 3.28’ club3d dp1.4 → KVM - 6.56’ fibbr → 1440p@165hz monitor ~ 3.28’ total copper and the difference is night-and-day. I have zero flickering issues across three different computers. I had random issues before where the refresh rate would change (probably due to a bandwidth negotiation issue) and that doesn’t seem to be happening. I’ve spent so much money on cables to dial everything in. The price we pay for productivity perfection!
