DisplayPort
DisplayPort is a widely spread audio/video interface standard designed by VESA (Video Electronics Standard
Association) in 2006. The aim was to create such an interface that would be the connection between graphic
cards and display devices. The standard is available and free thus it can be implemented widely, which could
help replacing the previously used interfaces, such as VGA or DVI.
Lightware’s DP-OPT extenders are designed according to DisplayPort standard 1.1a. The maximum allowed
bandwidth is 10.8 Gbps, which means e.g. 2560x1600 pixel resolution at 60 Hz or 4096x2400 pixels at 30
Hz. Color depth until 16 bits per color and 8-channel embedded LPCM audio is supported.
7.2.1.
Dual Mode
Mentioned standard was designed to support HDMI/DVI display devices too. If the sink is assembled with
DVI or HDMI input connector, it can be connected to a dual mode DisplayPort source by a passive adaptor
(DP++). In this case, source switches to DVI/HDMI mode and the signal is changed to be in line with DVI/
HDMI requirements.
INFO:
Most of the sources assembled with DisplayPort supports Dual mode, but if you are not sure check
the documentation of your device.
Passive adaptor
Display device with HDMI or DVI connector can be connected by a passive DP-HDMI or DP-DVI adaptor to
the source. The passive adaptor has two functions: sending a sign to the source if DVI or HDMI signal is
required, and doing level shifting from +3.3V to +5V. The source switches to DVI/HDMI mode and sends the
proper signal.
DP-DVI and DP-HDMI Passive Adaptors
