8.Notice
1. 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.
2. EIA/TIA-568-B termination (T568B) for CAT5e/6/6a/7 cables is recommended for better performance.
3. 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.
