1. If the DVI or HDMI/DVI device requires the EDID information, please use C-EDID-RW EDID
Reader/Writer to retrieve and provide DVI/HDMI EDID information.
2. All HDMI over CAT5 transmission distances are measured using Belden 1583A CAT5e 125MHz UTP
cable and ASTRODESIGN Video Signal Generator VG-859C.
3. The transmission length is largely affected by the type of category 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 or 1000ft bulk cable) can transmit a lot longer signals than stranded UTP cables
(usually in the form of patch cords). 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 cables are your only choice.
4. EIA/TIA-568-B termination (T568B) for category cables is recommended for better performance.
5. To reduce the interference among the unshielded twisted pairs of wires in category cable, you can
use shielded STP cables to improve EMI problems.
6. The quality of UTP/STP cables can affect the transmission distance.
7. The video quality is subject to the resolution of the source, also the connected display should be
compatible with the resolution of the source .
