IR would be routed only to the applicable source.
Do I need power at the TV end?
Yes. Our HD display adaptors require a 5v power supply
at the TV end to operate. It’s important that these are
powered locally and do not receive remote power from
the rack as there can be issues resulting from voltage
drop along the length of cable. Our new USB power
cables overcome the problem of having a second mains
outlet behind the TV. These useful leads draw the 5v from
the USB socket on the TV to power the receiver, this also
means that the receiver is only powered when the TV is
on making the system more environmentally friendly.
Are WyreStorm products compatible with
HDMI 1.4?
HDMI 1.4 refers to a list of ‘features’ that a device is
capable of supporting, including Ethernet channel, return
audio channel, 3D etc. Due to the continuously evolving
nature of the technology, HDMI Licensing LLC have now
decided to simplify terminology by testing and referring to
cable in terms of STANDARD or HIGH-SPEED rather than
in generations 1.3, 1.4 etc.
• STANDARD (or “category 1”) HDMI cables perform
at speeds of 75Mhz or up to 6.75Gbps, which is the
equivalent to a 720p/1080i signal.
• All WyreStorm equipment support HIGH-SPEED (or
“category 2”) HDMI cables that have been tested to
perform at speeds of 340Mhz or up to 10.2Gbps, which
is the highest bandwidth currently utilised over an HDMI
cable and can successfully handle 1080p signals including
those at increased color depths and/or increased refresh
rates from the Source. High-Speed cables are also able
to accommodate higher resolution displays, such as
WQXGA cinema monitors (resolution of 2560 x 1600).
What about screens with different
resolution capabilities?
When sending a signal point to point a TV will
communicate it’s capabilities to the source, then the
source will output a suitable signal that compatible (i.e.
1080p Stereo audio). If you were to use a matrix switch
with three 1080p screens and one 1080i screen, the
resultant image would be 1080i across all screens. The
matrix switches do not scale per output but instead
negotiate with the source a signal that all screens are
capable of supporting.
How do WyreStorm devices handle HDCP?
HDCP (High Definition Copyright Protection) is a feature
built in to HDMI devices to prevent theft of or illegal
distribution of HD content. Unlike competing products,
WyreStorm devices are legal and comply with HDCP
regulations. They do this by assigning a “key” to every
display connected to the switch. HDCP “keys” are
assigned to a display when connected to a HDMI device
normally. This doesn’t change when connected to a
switch; it just assigns more of them.
I can get 1080i but not 1080p at a TV
location
Firstly ensure that both the source is outputting 1080p
and that the TV is Full HD 1080p screen. If this is the
case then the receiver may need setting up for long cable
mode using the DIP switches. This useful feature uses an
alternative Equalisation method to re-sync the signal over
longer distances. (feature available on selected models)
I cannot get a signal out from my A/V
receiver along a Cat 5e extender set
Check to ensure that the A/V Receiver isn’t adding CEC
(HDMI Control Protocol) to the outgoing signal, this can
sometimes have an effect on the HDMI signal.
Clean this unit with a soft, dry cloth only. Never use
