1. If the DVI or HDMI device requires the EDID information, please use EDID Reader/Writer to
retrieve and provide DVI/HDMI EDID information.
2. All HDMI over CAT5 transmission distances are measured using Belden CAT5e 125MHz LAN
cable and ASTRODESIGN Video Signal Generator VG-859C.
3. 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 suited than unshielded UTP cables. A solid UTP
CAT5e cable shows longer transmission range than stranded STP CAT6 cable. For long extension
users, solid LAN cables are the only viable choice.
4. EIA/TIA-568-B termination (T568B) for LAN cables is recommended for better performance.
5. To reduce the interference among the unshielded twisted pairs of wires in LAN cable, one can use
shielded LAN cables to improve EMI problems, which is worsen in long transmission.
6. Because the quality of the LAN cables has the major effect on how long the transmission limit can
achieve and how good is the received picture quality, the actual transmission range is subject to
one's choice of LAN cables. For desired resolutions greater than 1080i or 1280x1024, a Cat-6
cable is recommended.
7. 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.
