This 4 port KVM switch combines 4K (60Hz) digital display capabilities with control of our connected computers. 4K 60Hz Picture and Full Audio Support The HDMI KVM switch supports resolutions up to 4K at 60Hz. It drives one large monitor at the full 4K resolution. Includes EDID and HDCP signal emulation so monitors always remain synced for faster switching times, and desktop settings are maintained to avoid disrupting your workflow. With support for digital audio (with supporting displays and sources) and separate 3.5 mm stereo audio, the HDMI 2.0 KVM switch delivers full audio compatibility. Integrated USB Hub The integrated USB 3.0 hub shares two peripherals (in addition to keyboard and mouse) among attached computers as if they were directly connected to your host computer, eliminating the cost of duplicate devices such as printers and scanners. Windows, Mac & Linux Compatible While supporting Windows, this HDMI KVM switch is also compatible with Mac and Linux operating systems. Easy to Operate The front-panel pushbuttons make it easy to switch between systems and activate the auto-scan feature. The hotkey functionality makes accessing each system quickly, while a buzzer sound confirms the switch.
