Maximum cable length for the HDBaseT connection: 70m (approx.). Full HD 1080p 60Hz (4:4:4 up to 16bpc) including 3D up to 70m. Ultra HD 4K 60Hz (4:2:0 12bpc) / 4K 24/30Hz (4:4:4 8bpc) up to 40m. I don't have any 4K sources so cannot test 4K, but as you can see from the last photograph, the units are working perfectly with full HD 1080 signals.
