Extron HDMI Ultra/12 (part number 26-663-12) — a 12 ft (3.6 m) Premium High Speed HDMI cable for the longer in-room run.

Twelve feet is usually where installers start worrying about 4K holding up. This assembly is specified for it: attenuation stays at or below 12 dB per 3 m through the 0.825 to 2.475 GHz band, intrapair skew is capped at 112 ps per 3 m, and the pairs hold 100 ohms ±10 ohms end to end. Physically it is still an HDMI Ultra cable, meaning a 0.22 in (5.7 mm) jacket and gold-plated type A plugs that measure 1.40 in long excluding the plug body.
