Mobile PCs embrace embedded DisplayPort

In-Stat forecasts that DisplayPort will see significant adoption in mobile PCs as an internal interface between the motherboard and the LCD panel. However, the market analyst cautions that DisplayPort's success in LCD monitors is much less certain, as LCD manufactures grapple with issues of backwards compatibility.

"We expect embedded DisplayPort to outpace DisplayPort ports in mobile PCs over the next few years, due primarily to the power reduction advantage," says Brian O'Rourke, In-Stat analyst. "Adoption in desktop PCs will be slower because embedded DisplayPort's power reduction is not as relevant in wired desktops, and external DisplayPort has tough display interface competition. In LCD monitors, DisplayPort enables direct drive monitors, which allows the elimination of the scaler chip and shifts the graphics control to the CPU or GPU in the PC. However, this means the monitors can no longer display VGA, DVI, or HDMI signals without an adapter, creating potential marketing and cost issues for monitor vendors."

Recent research by In-Stat found that shipments of DisplayPort-enabled devices will see a CAGR of 194 percent from 2008 to 2013, albeit from a very low base in 2008. 2010 will be a very significant year for DisplayPort, as both Intel and AMD are scheduled to release next-generation mobile and desktop PC chipsets and platforms that support it.
