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 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 be followed at all times 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.

Screen Material Installation
Back Side
Please read this important note before proceeding with the installation process of the material.
Before handling the DarkStar® 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 DarkStar® UST material is very delicate
and should be handled with extreme care. Do not allow the material to fold or bend. Failu r e to fo llo w
instructions will result in permanent damage to the screen material, which is not covered by warranty.
Step 7: It is strongly recommended for two people to unroll the material to prevent it from rolling unevenly.
Each person holds one end of the roll. Slowly unroll the screen in a clockwise direction.
Step 8: 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 (black) of the screen material should be placed upwards.
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 grommet hole located on the screen material’s
outer edge in the following order. Attach all four corners first (1) and (2) on the outer grommet holes. Then
attach the Extension spring (n) on the two inner grommet holes. See illus tration below.

After all four corner s have b een attache d , proceed to attach the vertical sides of the material. Begin in the cen ter
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.

and move towards the corners from (3) to (4) to (5). Lastly, attach the horizontal sides of the material by
starting with the center of the material and mak e y our way towards the corners from (6) to (7) to (8).
Note: Please make note of the yellow label and spring in the center of the frame. This is an indicator to start the
screen material instal la tion proce ss from the middl e are a of the frame.
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 s cree n m aterial 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 as much as possible, and reattach springs to the materi al.

Center Support Bar
Step 11: Insert the Center Support Bar (i) into the upper top groove on the back of the frame with the bot to m
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.

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.

Please use the following installation instructions to obtain superior optical performance from
EPV’s innovative DarkStar® UST screen materi al .
The DarkStar® UST is exclusively for table-mounted ultra-short throw projectors as illustrated in the
Example 1 diagram. 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.

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 lev eled.
Step 15: Position the fixed frame screen onto the top wall bra ck ets as shown below and push down at the center
of the top of the frame to secure.
