Home > Products > Selecting the Right Screen > Screen Borders and Drop Four Steps to Selecting the Right Screen Screen Borders and Drop Black masking borders are standard on all Da-Lite front projection screens at no extra charge. Borders enhance the perceived brightness of an image on a screen. The human eye perceives the image to have more contrast and a sharper picture with brighter colors. Borders also allow the projected image to "bleed-off" the screen for professional appearing presentations. Drop is also available on most Da-Lite wall and ceiling electric screens. Drop is extra fabric added to the top or bottom of the screen to adjust the screen surface to within normal viewing heights. Drop can be specified in either black or white.   For pricing information, please contact Media Fabricators, Inc. e-mail at [email protected] or via telephone at 323 937 3344.
