Projection Screen Manual Avtek International Video 175

The Avtek International Video 175 is a manual projection screen designed for 4:3 video formats with a viewable width of 170 cm and height of 127.5 cm. Housed in a white metal casing with black edging, the screen offers a matt white projection surface with a gain factor of 1.0 and black borders that improve perceived contrast. The lower bar is made of a hard material to protect the surface from creasing and features an adjustable height and a pull-up safety catch for controlled operation. The unit supports both ceiling and wall mounting and includes a black top section so the image can be positioned to the viewer’s eye level.

Advantages

The construction combines a durable white metal casing and a reinforced lower bar to reduce the risk of damage and surface creasing during use and storage. The matt white surface provides neutral color reproduction and even light diffusion suitable for presentations and home cinema. Black frames around the viewing area increase perceived contrast while the adjustable lower bar and black top allow flexible image placement. Manual drive with a pull-up safety catch enables simple, tool-free operation and reliable locking at the desired height.

How to use

Install the screen to a stable ceiling or wall mount according to the mounting instructions supplied with the product, ensuring fixings are suitable for the installation surface and load. Pull the lower bar gently to release the manual mechanism and set the screen to the required height; the pull-up safety catch will engage to hold the screen in place. Adjust the lower bar height if needed to position the image vertically using the black top to align the top edge with the viewer’s eye level. Retract the screen by releasing the safety catch and guiding the lower bar upwards to roll the surface back into the casing to avoid rapid retraction.

Usage recommendations

For optimal image quality, use the screen in a dim or controlled lighting environment and position the projector to match the 4:3 aspect ratio. Clean the matt white surface with a soft, dry cloth; avoid abrasive cleaners and excessive moisture. Verify that mounting hardware is rated for the installation and periodically check fixings and the lower bar for wear to maintain safe operation.
