Business owners who take particular pride in the design of their sales rooms are often faced with a dilemma when introducing digital signage: an emphasis on technology usually means sacrificing appearance. The NEC Option Slot for expansion modules such as the built-in PC or the DVI Daisy Chain Board offers technical as well as visual advantages. The extensions replace external distribution equipment and the cables they need to operate. And when it comes to sparing resources too, the Multeos devices are consistent. The built-in ambient light sensor measures the ambient lighting and ensures that the screen brightness is only as high as needed.¤¤With a range of interfaces, the Multeos M461 is equipped for all kinds of situations. As well as DVI and HDMI, it boasts a DisplayPort connection. The built-in Ethernet connection facilitates network integration, thereby enabling the screens to be controlled and managed remotely. An RS-232 interface enables the direct copying of device settings without having to adjust each screen manually with the remote control, thereby reducing installation costs.¤¤The display offers extended combination possibilities for picture-in-pictures from different signal sources. The simultaneous input for two PCs is now also possible via DVI and VGA. NEC also sets great store by user-friendliness. Different input interfaces, for instance, can be assigned informative names in order to make allocation easier. Another useful detail comes into play when the screen is used in portrait mode: the on-screen display rotates around 90 degrees, making it easier to operate.
