Would be nice to rackmount a few of my PCs in the garage and just gave displaylink devices on the desks kinda like dumb terminals. 3m USB 3 cable limit doesnt allow for this. Maybe its possible with usb extenders. But to get the hot and loud gaming PC's out of the rooms will be a win.
Freeze functions on classical projectors were very popular, in particular for people facilitating workshops or holding seminars. With the introduction of LCD screens this feature disappeared. Display link could easily re-introduce this. Ideally, hitting a (user-definable) key combination would turn PAUSE on and off. In addition the status (frozen / unfrozen) should be displayed with the application icon.
