Display Data (EDID) Learning & Programming
Detection of DDC signals for all attached devices is effortless with HDN-4Duo due to its real EDID learning and programming. This is vital in optimizing the resolution of the selected graphics card to properly display on the remote monitor. Furthermore, the EDID learning feature continues to replicate the right DDC for the computer to enable the display card to effectively work when unused ports are not selected.
Full USB Keyboard & Mouse Emulation
The USB keyboard and mouse emulation utilized by HDN-4Duo provides accurate and quick source switching by means of keyboard hotkeys and mouse actions. HDN-4Duo imitates the presence of a keyboard and mouse for every attached computer through a USB cable. This is essential as it simulates the existence of the keyboard and mouse to all the computers while switching without interruptions.
