For Cat 1, Type A, 15 meters for a AWG22, 12 meters for AWG24, and 10 meters
for a AWG26. For Cat 2, the maximum seems to be 5-8 meters
There are many HDMI Adopters working on HDMI solutions that extend a cable’
s effective distance from the typical 10 meter range to much longer lengths.
These companies manufacture a variety of solutions that include active
cables (active electronics built into cables that boost and extend the cable
’s signal), repeaters, amplifiers as well as CAT5/6 and fiber solutions. We
have seen cables pass "Standard Cable" HDMI compliance testing at lengths
of up to a maximum of 10 meters without the use of a repeater. It is not
only the cable that factors into how long a cable can successfully carry an
HDMI signal, the receiver chip inside the TV or projector also plays a major
factor. Receiver chips that include a feature called "cable equalization"
are able to compensate for weaker signals thereby extending the potential
length of any cable that is used with that device. | A*********l
发帖数: 2005 | 3 If you run the cable inside of drywall or ceiling, better buy quality HDMI
cable, so you won't have to replace it later. If you run it outside of
drywall/ceiling and can replace it easily, why not try some cheaper cables
first.
I have 25ft HDMI cable run through drywall/ceiling, and I bought the cable
from http://www.bluejeanscable.com/. It costed me around $90. The cable is very thick (diameter as big as a male adult's finger), the build quality feels really solid. Maybe cheaper cable will work for me with no problem, but I think the build quality of the cable I got make it less likely to fail and I shouldn't need to worry about replacing it later.
If you read HDMI cable reviews on Amazon, many people complains that their
HDMI cables stop working properly after some time. That's what triggered me
to buy the more expensive cable.
