Dell this weekend inadvertently let slip details that confirm its upcoming 27-inch computer screen. Accidentally posted at a product site for the 20-inch 2007WFP display, a diagram for the 2707WFP confirms the new display's existence and provdes additional details beyond those revealed in a Samsung statement last month. Dell's new screen will have a new display arm that eases adjusting the screen height and should retain the TV-oriented inputs of its 24-inch predecessor, including component video. USB ports and a 9-in-2 card reader are planned for the new LCD as well. While its price remains a mystery, the 2707WFP is expected to debut at CES next week and go on sale shortly afterwards.
