Designed for demanding professional applications in corporations and industries such as engineering, desktop publishing, imaging and CAD/CAM, the 447PRO 17" (16" viewable image size) display uses the firm’s Flat AG technology with the flat FD Trinitron CRT. With resolutions up to 1280 x 1024 pixels at a refresh rate of 90 Hz, images are reported as being flicker-free. Horizontal frequency ranges from 30 to 90 kHz, and aperture grille pitch is 0.24 to 0.25 mm. The flat CRT surface reduces geometric distortion and reflective glare. The display comes with an active USB hub and the firm’s Business Audio system that offers two 5W speakers located at the front of the unit and a personal headset jack for stereo sound.
