calibration over the life of the display and can control the back light system
automatically to extend the life of the monitor and achieve very short warming up
time.
Multi-interface for video inputs- Support DVI-D,DVI-A,BNC (combined with
optional BNC cable) video inputs.
Digital control interface-The monitor has an asynchronous RS-232 architecture
interface for remote control, such as Brightness, Contrast etc. The protocol of RS-232
is compatible with GE OEC 16 inch CRT monitor.
Left and Right Monitor-The monitor can be supported in pairs. The left monitor has
protective glass in the front and the right monitor has infrared touch screen in the
front.
Remark -All relate to the touch screen only applies to HL1928M-R.
