8. Notice
1. All HDMI over CAT5 transmission distances are measured using Belden 1583A CAT5e 125MHz UTP
cable and ASTRODESIGN Video Signal Generator VG-859C & VG-870B.
2. The transmission length is largely affected by the type of CAT5e/6/6a/7 cables, the type of HDMI sources,
and the type of HDMI display. The testing result shows solid UTP cables (usually in the form of 300m
[1,000ft] bulk cables) can transmit a lot longer signals than stranded UTP cables (usually in the form of fixed
length patch cords). Shielded STP cables are better suited than unshielded UTP cables. A solid UTP Cat-
5e cable shows longer transmission range than stranded STP Cat-6 cable. For long extension applications,
solid UTP/STP cables are the only viable choice.
3. EIA/TIA-568-B termination (T568B) for CAT5e/6/6a/7 cables is recommended for better performance.
4. The quality of CAT X cables on the market may vary greatly. Reducing the number of RJ45 patches, using
higher quality cable and choosing a higher Cat X number will invariably yield better results.
