admin Ready to buy a projection screen but do not know what is meant by the different styles to choose from, the business offered. Some ideas to narrow your choices.
Step 1: What kind of screen you want?
- Fixed frame screen. Installed in a fixed location. Ready to use at any time.
- Motorized screen. Installed in a fixed location. Press remote to use screen.
- Manual pull-down screen. Installed in a fixed location. Drag the screen to use.
- Pull-up Screen. Can also be worn
Step 2: What kind of audio-format you want?
- 01:01
- 4:03, such as TV and PC monitors
- 16.09 clock, such as screens
Step 3: What color you want to see?
- White
- Gray.
Screen-white vs. gray screen debate. It is said that the gray screens absorb ambient light better. There is more contrast, because the colors appear darker black. White screens are ideal for those who use the latest models with high contrast projectors.

Step 4: What materials do you want?
Select the fabric of your projection screen. Note that the gain in brightness from the center of the screen. A gain of 1.0 means that the amount of light is projected onto the screen back to the viewer the same brightness: not everything is absorbed and re-radiated with perfect uniformity from all angles.
Glass beads. High optical gain of more than 2.9, effective scattering angle more than 32, high contrast and resolution, fine color rendition, excellent vision. Reflective beads are air insulated and permanently attached to the surface of the screen. Screen surface is flat, prevents mold, moisture and odors. Refractory. Brightness does not decrease with time.
Pearlux tissue. High optical gain of more than 1.4, effective scattering angle more than 100, high contrast and resolution, fine color rendition, good vision in bright light conditions. Stable physical parameter and less attenuation. Flat and odorless.
Gray glass beads. High optical gain of more than 2.8, effective scattering angle more than 32, high contrast and resolution, fine color rendition, excellent vision. The best choice for home theater. Tissue increases the color saturation of black and gray, enhances the contrast. Reflective beads are air insulated and permanently attached to the surface of the screen. Screen surface is flat, prevents mold, moisture and odors. Refractory. Brightness does not decrease with time.
Matt White.
Diffusion screen surface with effective scattering angle of 160 degrees, high brightness coefficient (about 0.92), anti-glare, fine color rendition, wide viewing angle, soft light. No strain on the eyes, when I had a long time. Stable physical parameter, less attenuation.
Grey Matt White
Diffusion screen surface with effective scattering angle of 160 degrees, high brightness coefficient (about 0.85), anti-glare, fine color rendition, wide viewing angle, soft light. No strain on the eyes, when I had a long time. Stable physical parameter, less attenuation. Odorless
Gray vinyl
PVC screen surface with effective scattering angle of 160 degrees, high brightness coefficient (about 0.82), high contrast, wide viewing angle, soft light. No strain on the eyes, when I had a long time. Stable physical parameter, less attenuation, flat and free of odor. Odorless.
White vinyl
PVC screen surface with effective scattering angle of 160 degrees, high brightness coefficient (about 0.90), fine color reproduction, high contrast, wide viewing angle, soft light. No strain on the eyes, when I had a long time. Stable physical parameter, less attenuation, flat and free of odor. Odorless.
Step 5: What size screen do you want?
As for the screen size, you:
The diagonal is the distance from a bottom of the screen on the corner diagonally across the top. Diagonals are always specified with the specifications.
Removal is appropriate to consider equal to the diagonal of the screen.
- The recommended width of the screen:
If you want a 4:3 ratio, the width is Diagonal times .80 (P = 0.80 x diagonal)
If you want an aspect ratio of 16:9, is diagonal wide by 0.82 (P = 0.82 x diagonal)
- The recommended height of the screen:
If you want a 4:3 ratio, the width is Diagonal times .60 (P = 0.60 x diagonal)
If you want an aspect ratio of 16:9, wide Diagonal times .49 (P = 0.49 x diagonal)
- Write down the margin of the room through the screen when it is installed is required. The recommended distance between the ground and the bottom of the screen from 0.7 to 1.25 meters.
For example, you plan to buy 100 electric screen with 4:3
First The screen size is
Diagonal = 100
Width W = 0.80 x diagonal
W = 100 x 0.80
W = 80 in
Height H = 0.6 x diagonal
H = 0.6 x 100
H = 60 in
The screen size is 80 x 60 in
Second And place for your screen
The width is greater than 80 inches – 80 inches, plus an allowance on the sides
Height must be greater than 60 inches – 60 inches from the floor space.
Reflecting on these factors in advance You can choose to limit the projection, which is perfect for your needs and use. Fergameri USA offer the best screen suitable for you at affordable prices.
