Fixed Frame Screen
USER’S GUIDE
Product Description:
The Dark Star®UST 2 eFinity Series is a fixed frame projection screen that uses EPV’s EDGE FREE®
technology. The EDGE FREE®design resembles a flat panel TV display. The Dark Star®UST 2 includes
a micro-thin bezel trim to further enhance the frame appearance and absorb projector overshoot.
The screen material included is our Dark Star®UST 2, which is an optical lens front projection material
precisely formulated for environments with minimal control over room lighting. It was designed to filter
and absorb overhead light while directing table-top mounted ultra-short throw projection. It best for family
rooms, educational facilities, conference rooms or any applications in which incident light is a factor.
Screen maintenance
Dust, dirt and scratches on the projection screen surface will affect the quality and performance of the projection
image. Follow the instructions below to properly maintain the screen.
1) The screen surface has a horizontal linear structure. DO NOT wipe the screen up and down or in a
circular motion. Wipe gently from left to right only.
2) Clean the dust on the screen surface with a soft brush or microfiber cloth. A rough/coarse towel or
cloth may damage the screen’s surface.
3) Gently wipe the screen with a lightly moistened white lint free cloth with water or with a neutral
detergent (1mL/0.33 oz) mixed with water (1000 mL/33.8 oz).
Notes: The following precautions should always be followed to avoid damaging the material, which is
not covered under warranty.
•Don’t touch the screen material to avoid leaving fingerprints.
•Use gloves when handling the material.
•Don’t scratch the material, as it will leave permanent markings on the screen’s surface.
•Don’t point to the screen material with a fingertip or other sharp objects to prevent damage to the
material.
•Don’t use acetone, benzene, alcohol and any other organic solvents to clean the screen material.
Using such chemicals will permanently damage the screen.

Step 3: Insert center joint (a/b) connectors into one-half of the horizontal frame (B/C) and secure with the M4x7
screws (g) as shown in the illustration below.
Tip: The center joint (b) with the larger diameter holes should be on top.
Step 4: Connect the elbow joints (c/d) to the top and bottom sections of the vertical frame. Once inserted, connect
the vertical sections to the horizontal frame sections. Make sure all holes are in alignment and the frame pieces are
flush (no gaps). They should form perfect right angles.

Step 8: Carefully and gently place the assembled frame on top of the screen material in the marked areas as shown
below. Make sure to not allow the angle edge of the frame to come in direct contact with the screen material to
avoid puncturing it.
Step 9: Hook one end of the spring and secure inside the groove of the frame, use the spring hook (i) to attach the
spring to the hole located on the screen material’s outer edge in the following order.
Begin by first attaching the center points on both vertical (left/right) sides, steps 1-2. Then the center points on both
horizontal (top/bottom) sides, steps 3-4. Once all center points have been secured, make sure the screen material is
still within the marked areas before proceeding to attach the next springs.
Continue attaching the rest of the springs to the material in the following order in steps 5-12.

Note (after all springs have been attached):
Correct material installation –Corners of the screen material are properly wrapped around the corner edges of the
frame and material is evenly tensioned and flat, creating a nicely taut surface.
Incorrect material installation –The corners of the screen material are not properly wrapped along the edge of the
frame leaving the material with unbalanced tension and an uneven finish. To correct, detach springs from material at
the corner(s) where material does not lie flat along the edge of the frame, reposition the material so that it lies flat
and wraps along the edge of the frame, and reattach springs to the material.
Edge Trim Installation
Step 10: Place the edge trim frame pieces over each end of the frame.
Connect edge trim frames (E/F) together using the Center Joints- M4(a) and secure with four of the M4x4 Screws(m)
as show in Step 1. Repeat for other side.
Once both top and bottom edge trim frames have been connected, attach the vertical (left/right) sides edge trim
frames (D) using the Elbow Joints M4 (c) and secure with four M4x4 screws (m) on all corners, Step 2.
Step 11: Install the angle cover (n.) on each corner of the frame using the double-sided tape.
To avoid ripples forming in the material it is imperative that all of the corners are properly wrapped around the
edges as illustrated in the check mark diagrams.

Attention: The back of the material has labels indicating the TOP and BOTTOM. The top edge trim piece with
the logo should be installed at the top. The material is directional so it will not properly reflect if bottom side is
projected on.

Notice to Installer:
Material Tip: Proper Projector Placement for DarkStar®UST 2
The DarkStar®UST 2is exclusively for table-mounted ultra-short throw projectors.
Overhead placement or a standard projector will make the image very dark, on account of the screen’s absorbent
layer deflecting light that is not aligned with its reflective angle.

Wall Installation
Step 13: Measure the overall length and height of the frame and drill holes for the top brackets. Line up the wall
brackets with the drilled holes on the installation location and screw them in using a Phillips screwdriver. If not
installing into a structural wood stud, use a hollow wall anchor then screw in the M5x50 wood screws with a
screwdriver. Make sure the brackets are leveled.
Step 14: Position the fixed frame screen onto the top wall brackets as shown below and push down at the center of
the top of the frame to secure.
