8-port HDMI KVM switch 

with on-screen display (OSD) and serial control; USB 2.0 peripheral sharing 

SM-UHO-8P HDMI-USB KVM switch allows a single user to control 8 Ultra-HD 4K 30Hz USB computers with one USB keyboard, USB mouse and a 4K HDMI monitor. Dedicated internal microprocessors emulate keyboard and mouse presence to each attached computer 100% of the time so all computers boot-up error-free.

SM-UHO-8P HDMI-USB KVM switch features an on-screen display (OSD) and a built-in fully transparent USB 2.0 hub. This means that when a USB device is connected to a transparent USB port, it is the same as if the device was being plugged directly into the computer's USB port. The transparent USB hub is capable of supporting any two low- full- or high-speed USB 2.0 devices, including but not limited to card readers, printers, scanners, and thumb drives. This built-in USB 2.0 hub enables the use of a USB keyboard and mouse on one computer while other USB peripherals are connected to a different computer. 

Connections use standard HDMI and USB cables.

SM-UHO-8P supports 4K video resolution up to 3840x2160 @ 30Hz with zero pixel loss from TMDS signal correction.

Flexible Control
Switching between computers is simple: Use the push-buttons on the front panel, or the programmable keyboard hot-keys, or RS-232 commands, or use the built-in on screen display (OSD).
• The OSD is accessible at the press of a button, and features controls for all of the SM-UHO-8P's functions. The SM-UHO-8P is easily programmable through the setup function of the OSD.
• Any external device or program supporting RS-232 can control SM-UHO-8P. SM-UHO-8P uses a very simple protocol, enabling easy integration with the RS-232 control devices.
• Hot keys enable the user to switch and control all the different functions of the KVM switch via the connected keyboard.
