Why can’t I see standard definition on my HDMI-based TV?
The HDLink and HDLink 2 models were originally designed for use with DVI displays before HDMI was
widely available. HDMI support was subsequently added with a HDLink software update which upgraded
the firmware in both the HDLink and HDLink 2 models. This firmware update exclusively supported high
definition video formats and not standard definition. If you need to monitor standard definition with these
models of HDLink, you will need to use a DVI-based monitor. If your DVI monitor supports 1920 x 1200
resolution, you may wish to use the Enable 2x Scaling of SD Video setting in order to mostly fill the display
with your video. This will minimize the black borders around your standard definition video. Blackmagic
Design has newer HDLink models which support standard definition via HDMI.
Why can’t I hear audio on my HDMI TV?
The original HDLink and HDLink 2 were originally designed for use with DVI displays and the DVI
standard does not support audio. That is why stereo, analog, RCA ports are provided on the HDLink
for low cost, 2-channel monitoring of SDI audio. HDMI support was subsequently added with a HDLink
software update which upgraded the firmware in both the HDLink and HDLink 2 models. This firmware
update exclusively supported high definition video formats via HDMI but audio must still be monitored
via the analog outputs. Analog audio can be connected to an amplifier for audio monitoring and some
HDMI-based TVs also provide analog, RCA audio inputs which makes it even easier to connect the HDMI
video and analog audio directly to the TV. Blackmagic Design has newer HDLink models which support
2-channel audio monitoring via HDMI.
Why can’t I use a 30” DVI monitor?
HDLink and HDLink 2 models connect to DVI-based monitors via a single-link DVI-D connection. This
includes LCD computer monitors with a resolution of up to 1920 x 1200 pixels. Larger monitors, such as 30”
LCD computer monitors, support higher resolutions but require a dual-link DVI-D connection. Blackmagic
Design has newer HDLink models which support 30” dual-link DVI-D LCD computer monitors as well as
smaller single-link DVI-D monitors.
