Screen Maintenance
Dust, dirt and scratches on the projection screen surface will affect the quality and performance of the
projection image. For optimal results we advise to pay attention to the following instructions.
1) The screen surface has a horizontal lens structure. DO NOT wipe the screen up and down or in a circular
motion. Wipe very gently from left to right only.
2) Please clean the dust on the screen surface with a soft brush or microfiber cloth (rough towel or cloth
may damage the screen’s surface).
3) Gently wipe the screen with a moistened microfiber cloth with mild soap diluted in water.
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 4: Insert the center joint (a) connectors into one-half of the horizontal frame (b/c) and secure with the
M4x6 screws (c).
Step 5: Connect the elbow joints (b) to the top and bottom sections of the vertical frame. Once inserted, connect
the vertical sections of 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 6: Secure the elbow joints by fastening them with M4x6 screws (c), 4 at each corner.
Screen Material
Please read this important note before proceeding with the installation process of the material.
Before handling the Dark Star® UST material, put on the supplied pair of white gloves to avoid leaving
fingerprint marks, dust or hand oil on the material’s surface. The Dark Star® UST material is very delicate
and should be handled with extreme care. Do not allow the material to fold or bend. Failure to follow
instructions will result in permanent damage to the screen material, which is not covered by warranty.

Step 7: Put on the white gloves (m) and carefully unroll the screen material on a clean surface from the roller to
the other side as shown below. The back side of the screen material should be placed upwards.
Step 8: Insert the fiberglass rods (n) through the openings. The longer rods are used on the vertical edges of the
screen material, and the shorter rods are used on the horizontal edges, as shown below.
Step 9: Carefully and gently place the assembled frame on top of the screen material. Make sure to not allow
the angle edge of the frame to come in direct contact with the screen material to avoid puncturing it.
Note: Make sure all of the corners of the frame are aligned according to the markings on the back of the
material as indicated below.

Step 10: Use the spring hook (d) to attach the spring (e) to the hole located on the screen material’s outer edge
in the following order. Make sure the spring hook goes over the rod.
Attach the four corners first (1).
After those are secure, connect the vertical portions of the material, begin in the center and move towards the
corners (2). Lastly, connect the horizontal sections of the material by connecting the center of the material and
make your way towards the corners (3).
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.
To avoid ripples forming in the material it is imperative that all the corners are properly wrapped around the
edges as illustrated in the check mark diagrams above.

Center Support Bar
Step 11: Insert the Center Support
Bar (i) into the upper top groove on
the back of the frame with the bottom
end near the approximate center point
of the frame and rotate it in at an angle
so that both ends of the bar are in
alignment with the groove.
Attention: Do not proceed with the Edge Trim installation until making sure there are no ripples in the material.
Pre-check prior to Edge Trim Installation
Correctly distinguish the top
and bottom of the DarkStar®
UST material. Place the
assembled screen on the ground.
Look down on the screen. If the
material looks white/gray as
shown below then it is correct.
If the material looks black as
shown below, then it is upside
down.
Edge Trim Installation
Step 12: Place the Edge Trim over each end of the frame and secure with M4x6 screws (c).
Start with the center points first, then the rest of the corners as shown below.

Step 13: Install the angle cover (j)on each corner of the frame and install the LED light strip to hold down the
angle cover (or just use the clips if LED kit will not be installed). Then insert the LED light clip (l) to hold the
LED light strip in place.
Wall Installation
Step 14: 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.
