NOTICE
1. If the DVI or HDMI 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
double shielded STP cables to improve EMI problems, which is worse in long transmission.
6. Because the quality of the category 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 category
cables. For resolution greater than 1080i or 1280x1024, a solid CAT6 cable is the only viable choice.
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.
