Dell moved ahead of Samsung in the worldwide PC monitor market for the first time since 2007, shipping more than 5.0 million units in the second quarter of 2013 (2Q13), according to the International Data Corporation (IDC). "Dell grew its unit shipments by 12.7% compared to the first quarter of 2013, which vaulted the company into the number one position worldwide. However, Samsung continues to be the worldwide revenue leader, despite its declining shipment numbers," said Jennifer Song, Research Analyst, Worldwide Trackers at IDC. "On a geographic basis, China remained the largest market for PC monitors with 29.2% share, followed by the U.S. with 18.4% share. The number three market, Brazil, trailed by some distance with 4.3% share."

Looking ahead to the third quarter of 2013, IDC is forecasting 0.7% quarter-over-quarter shipment growth to 33.8 million units. IDC also slightly raised its total shipment forecast for 2013 from 134.4 million units to 134.7 million units, which represents a year-over-year decline of -9.7%. By 2017, worldwide shipments are expected to drop further to 110.8 million units, lower than the previous forecast of 113.6 million units, as the adoption of mobile devices at lower price points is expected to continue.
