Display multiplexers provide a convenient way for the chipset to connect to either a DisplayPort connector or a PCI Express slot, based on which device is active or connected. These multiplexers are high-bandwidth passive switches that connect one port and isolate another based on the desired position of the switch. To support Gen 2 PCI Express graphics slots, multiplexers are available that support up to 5 Gbps link speeds. When the mux connects to a DVI or HDMI connector, a Level Shifter is additionally needed. Level Shifters and Muxes thus work together to provide the optimal cost-effective solution for graphics and display connectivity around the PC. As shown on the current slide, muxes are used in desktop motherboards to connect one source to a DisplayPort/DVI/HDMI connector or to a x16 PCIe Gen2 connector. Notebooks with docking stations can use a mux to support DisplayPort output.
