1.
The CV-117 may not be compatible with the DVI sources and displays that feature resolutions not in the
aspect ratio of 4:3, 16:9 and 16:10.
2.
All DVI over CAT5 transmission distances are measured using Belden 1583A 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 DVI sources, and the type of
DVI 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.
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, you 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 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.
