The future of collaboration

Instant engagement: With InGlass™ 20-point touch capability, multiple users can interact with the screen at the same time.

Intuitive technology: Experience natural touch functionality, a feature that allows you to annotate with your fingers, write with a stylus*, or even erase written content with the palm of your hand with virtually no lag. And, since the touch functionality is compatible with most industry-standard software (as well as included FlatFrog software), it integrates seamlessly into however you work.

More ways to display: Quickly tile and arrange your applications by conveniently selecting from predefined templates with the Easy Arrange feature on Dell Display Manager software. You can also start presentations faster with Auto-restore, a feature that remembers your last presentation layout.
