5. FEATURES
• HDMI with 3D & 4Kx2K supported, HDCP and DVI compliant
• Simultaneous HDMI and CAT5e/6/7 outputs
• Supports data rate from 250Mbps up to 3Gbps
• Supports wide range of PC resolutions from VGA to WUXGA
and HDTV resolutions up to 4Kx2K (3840x2160@24/25/30Hz and
4096x2160@24Hz).
• Supports LPCM 7.1CH, Dolby TrueHD, Dolby Digital Plus and DTS-HD
Master Audio transmission (32-192kHz sample rate)
• Supports distances up to 60 meters through CAT5e/6/7 cables
• Supports USB service port
• Supports Bidirectional IR control
• The 3D signal display follow by display TV’s EDID
Note:
1. This system was tested with CAT6/23AWG cables, results may vary
with cables of a different specifi cation.
2. Displaying HDMI 4Kx2K resolution require the standard 4Kx2K HDMI
cable and display in order for proper image displaying.
3. This device obtain the last memory function therefore, the device
will use last CAT5e/6/7 output port's EDID when CAT5e/6/7 output is
not connected to a display after power cycling.
The unit will detect CAT5e/6/7 output's EDID when it obtain a 4Kx2K
EDID and send out the signal accordingly to other output ports. If
the CAT5e/6/7 output is without a 4Kx2K's EDID the unit will detect
all output's EDID and send out the signal that all outputs can
accept.
