ViewXpand™ Multi-Monitor Controller IC

The VMM1400 is a VESA DisplayPort™ v1.1a, HDMI v1.3 and VESA DDM Standard compliant Multi-monitor controller with a single DisplayPort input port and four HDMI or DVI output ports. After initialization, the VMM1400 senses the number of monitors connected to its output ports, retrieves the Extended Display Identification Data (EDID) for each of the attached monitors, generates corresponding combined resolutions of EDID, and presents this onto the DisplayPort interface while triggering Hot Plug Detect (HPD). From the PC perspective, only a single big screen monitor is seen.

The generated EDID will give the user both expanded and original resolution options. When expanded resolution is selected, the VMM1400 will expand the PC desktop to the attached monitors as though only a single monitor were attached. When a display resolution the same or smaller than the monitor’s native resolution is selected, the VMM1400 will send the identical PC desktop screen images to each attached monitor.Both the input and output ports are protected with security circuitry that is fully compliant with the industry standard HDCP v1.3.

In addition the ViewXpand family also includes the VMM1300 - the world’s first VESA DisplayPort™ (DP) -based multi-monitor controller IC. It is fully compliant to the DisplayPort v1.1a and the VESA Direct Drive Monitor (DDM) standards.

The device integrates a DisplayPort receiver and multiple transmitters into a single chip, providing a high bandwidth, superior performance and cost effective solution for multiple PC monitor and display panel products. The patented technology provides complete high-definition multi-monitor capability without the need for a graphics card for each monitor. The IDT VMM1300 enables manufacturers to significantly simplify multi-monitor system design and provide the flexibility to customize the multi-monitor experience for their customers.
