Projector
The standard Q-1500d projector, shown Figure 2-2, consists of two discrete LED optical
engines stacked one on top of the other. The “primary” optical engine (the one nearest the
glass) receives an HDMI video signal from the Primary DHD Controller. The “secondary”
optical engine (the one nearest the feet) receives an HDMI video signal from the
Secondary DHD Controller. The projector superimposes the output from one engine onto
that from the other engine to produce an extremely bright and focused image.
Figure 2-2. Standard Q-1500d Projector Functional Components
• PROJECTION LENS
Available in two versions: standard throw range (1.94:1 to 2.40:1) and short throw
range (1.64:1 to 1.86:1).
• LENS LOCK
The screw to the right of the lens activates the lens lock, which freezes the zoom and
lens shift settings to keep the projector images aligned over time.
When shipped from Runco, the lenses are unlocked. To lock the lens position, use the
same 5.0-mm Hex wrench (provided) that you use for lens shift adjustments. (Turn
clockwise two or three turns.)
THE LENS SHIFT MECHANISM CAN BE DAMAGED BY
EXCESSIVE FORCE.
• Ensure that the lens lock is released before adjusting horizontal
or vertical lens shift.
• Do not attempt to move the primary lenses beyond their normal
adjustment ranges.
