The unit hosts two digital SDI inputs. These are configured as inputs 0 and
The HDP also supports DVI (with HDCP) and has two DVI jacks. These inputs
will support HDMI as well, although I did have trouble with 480i and 576i through
the DVI jacks with HDMI sources.
By way of outputs, the unit contains a set of five BNC connectors (RGBHV or HD
Component) as well as a single output DVI connector. You can turn on both
outputs through the service menu.
Finally, the unit contains a useful RS-232 jack that can be connected to
a home automation system (Crestron, AMX, and the like) and also serves to
upload the frequent firmware update.
The unit does not provide global audio delay (lipsync) support. I personally do not
normally use the lipsync features on other scalers, but I do think this is
an important feature for Lumagen to add in future products, particularly as
so many A/V receivers do such an awful job at doing digital lipsync
adjustment. (Lipsync is needed when the video ends up perhaps 30
milliseconds later than the audio, due to video processing delaying the
picture getting to the display).
Connecting with the Display
Although the original Vision processor had somewhat of a learning curve,
once you adapted to its mindset, there was almost nothing you couldn't do
with it. The endless range of features could be adapted to most common (and
Well, the list of features on the HDP VisionPro puts the original Vision and most
other processors to shame.
While it did take some time for all of these features to interact
flawlessly, Lumagen worked tirelessly and did not abandon the product. This
earned the company a great reputation with customer support and reliability.
The unit uses almost the same UI as the original Vision, an old school
textual menu system that should have been improved ages ago. The VisionPro
HDP has an LCD that helps figure out where you are in the menu system. This
is particularly useful when no image is shown on screen, which can happen
when playing with output parameters like resolution or output rate.
The menu system is not always easy to understand, because of its extensive
use of acronyms. This is due to simple lack of on-screen space. There are
not too many items to learn, so the installer can easily
learn them. Regular consumers wouldn't usually need to use the menu system at
all, as the unit would typically be put into Home Theater installations
that either have some automation in them or that use a smart macro-enabled
remote control. The processor provides discrete access to most common
features – so the unit can be made virtually transparent to the end user.
Step by Step
The first part of setting up any processor is setting up the output timing.
This is performed by specifying the output format. Advanced users can also
set up specific timing values, albeit the menu system can make this
procedure a tad complex. I would love to have the option of changing
individual output timing values like back and front porch by scrolling up
and down and not just entering them manually. The unit comes with quite a
few preset timing values that fit most displays. From those base settings,
one can adjust the rest of the parameters to achieve virtually any timing
that the unit supports.
Once the output timing has been set, one can use the HDP's test patterns to
ensure that black and white detail levels are set up correctly, ensure that
the signal is being mapped on screen correctly, as well as to determine if
native rate (the display's sweet spot resolution) has been achieved. A
special warm-up menu is intended for warming up projectors slowly.
Reaching the test patterns requires use of the menus. This is one feature
that I would prefer to be able to reach discretely using one touch of the
original remote control. But, again, this is something that the consumer
would not need on a day to day basis.
