I work for Stewart's Marketing Dept and may be able to help.
We have a variety of sample sizes we can send you. Please email me your address and we will send you the requested material.
Below is a good guideline in reviewing screen samples.
HELPFUL HINTS FOR EVALUATING SCREEN SAMPLES
Tape screen sample(s) to a flat vertical surface, such as a wall. Ordinary masking tape works well. Screen samples should be perfectly flat with no wrinkles.
It is much more efficient to study and evaluate still images rather than chasing an image in motion. From a video source, select an appropriate image and freeze the frame. Be sure to select a variety of material, such as a bright daytime image with deep shadows. Also, project images with dark screens, such as a night shot, to evaluate shadow detailing and black levels.
Evaluate the image quality from an appropriate viewing distance. Both the projector and screen will not look true at very close viewing.
Evaluate the screen performance from different seats and viewing angles. Try the seat which is the least perpendicular to the screen's centerline.
Introduce ambient light into the room. Try to duplicate actual conditions that you wish to view your system.
Position your projector in the same vertical orientation that will be permanently used. Some screens are gain sensitive to a floor or ceiling mount projector.
Try out these steps with your samples. It may help you in your decision. As Darren said read old posts, study your options, and make an educated decision.
