Notice
1. All HDMI over CAT5 transmission distances are measured using Belden 1583A CAT5e 125MHz
LAN cable and ASTRODESIGN Video Signal Generator VG-859C.
2. The transmission length is largely affected by the type of LAN cables, the type of HDMI sources,
and the type of HDMI display. The testing result shows solid LAN cables (usually in bulk cable
300m/1000ft form) can transmit a lot longer signals than stranded LAN cables (usually in patch
cord form). Shielded STP cables are better suit than unshielded UTP cables. A solid UTP CAT5e
cable shows longer transmission length than stranded STP CAT6 cable. For long extension users,
solid LAN cables are your only choice.
3. EIA/TIA-568-B termination (T568B) for LAN cables is recommended for better performance.
4. To reduce the interference among the unshielded twisted pairs of wires in LAN cable, you can use
shielded LAN cables to improve EMI problems, which is worsen in long transmission.
5. Because the quality of the LAN cables has the major effects in how long transmission distance will
be made and how good is the received display, the actual transmission length is subject to your
LAN cables. For resolution greater than 1080i or 1280x1024, a CAT6 cable is recommended.
6. If your HDMI display has multiple HDMI inputs, it is found that the first HDMI input [HDMI input #1]
generally can produce better transmission performance among all HDMI inputs.
