ViewSonic's 42" CD4220 commercial display features an elegant slim bezel design that's ideal for public information. The high brightness and contrast ratio and wide viewing angles clearly communicate your message regardless of ambient light. Create a 5x5 display video wall for maximum impact. The fast response time delivers blur free scrolling text or video. VGA and RS-232 inputs/outputs allow you to daisy chain multiple displays into your network and still control each display individually. The CD4220 sets a new standard for large format, high-impact digital signage.
