IDC lowers Q1 2013 global PC monitor shipment estimates from 34.7 million units to 33.8m, a 9.9% Y-o-Y decline caused by the continual drops in desktop PC shipments.

The analyst expects WW monitor shipments to drop further to 113.6m units by 2017.

"The continued decline in PC desktops is bringing about changes in strategy and product focus in the PC monitor market," IDC says. "With Windows 8 we expect to see more touch-based monitors although price points are a little high. Average screen size is also expected to increase to 21.4-inch in 2017 from 20.4-inch in 2012."

LED Backlit technology holds 69.2% Q1 2013 market share with 26.6m units, a 15.7% Y-o-Y increase. The aspect ratio of choice remains 16:9 with around 75% market share.

Monitors armed with TV tuners should see growth in the future-- IDC forecasts 7.6% 2017 share, up from 5.7% in 2013.

When it comes to vendors, Samsung remains on top with 14.4% WW market share despite -19.6% Y-o-Y decline on shipments of 4.8m units. Dell follows with 12.7% share, while HP is 3rd with 11.2%.
