HDMI cables can make or break the installation
Radiance Pro outputs have fast 4k edge rates, and cable equalisation.
Due to transmission line physics, it is edge rate, not data rate, that is the primary factor in required cable quality
Passive HDMI cables should be at least 2 meters long and no more than 5 meters long, with 3m often the optimal length for cable attenuation
All HDMI cables should be 18 GHz Certified. Passive 48 GHz HDMI cables can work, but you may need them to be longer to have the appropriate amount of attenuation
Avoid Baluns at 4k. We have reports of issues with these (including systems without a Radiance Pro)
Avoid using active cables on source outputs as often sources do not have enough HDMI Output Standby Power to reliably drive active cables
Avoid“8k active cables” for 4k systems to work at 48GHz they need to have faster edge rates, which can cause issues in an 18 GHz system
