HDBaseT / HDMI Distance

Pick the transport (passive copper HDMI, HDBaseT 2.0 or 3.0), the resolution/rate and the cable category, and get the maximum typical video distance plus a cable recommendation. These are standard reference values: they vary by extender and cable quality.

Passive HDMI = a direct HDMI cable. HDBaseT = an extender over twisted pair (RJ45).

Cable category

Cat6A = full distance. Cat6 ≈ −30 %. Cat5e ≈ −40 %.

 Typical standard values: the real distance varies with the
        extender (chipset), cable quality and the installation.

 How to read the table · assumptions 
 
 1. Passive HDMI: a direct HDMI
            cable, no extender. Distance drops fast as resolution rises because of
            copper attenuation.

 
 2. HDBaseT 2.0 (class A) carries
            up to 100 m for signals up to 10.2 Gbps
(1080p60, 4K30 4:4:4, 4K60 4:2:0). Above that, 4K60 4:4:4
uses compression and the usable length drops to ~40 m.
            It does not support 8K.

 
 3. HDBaseT 3.0 raises the
            bandwidth: 4K60 4:4:4 and 8K30 reach
~100 m over Cat6A.

 
 4. Cable category: HDBaseT distances are given
            over Cat6A. With Cat6 subtract
~30 % and with Cat5e subtract ~40 %.
