As the adoption of cheaper mobile devices continues, worldwide shipments of PC monitors will be less than 100 million units by 2020.

That's according to analyst firm IDC, who just released its quarterly worldwide PC monitor tracker results.

Maura Fitzgerald, senior research analyst of Worldwide Trackers, says the second quarter proved better than forecast overall.

“However, IDC expects the global monitor market will continue to decline at rates around 3% year over year from 2018 through 2020," she says.

Currently, it is IDC's understanding that 118 million PC monitor units will be shipped for the full year of 2016. The analyst firm also predicts a year-over-year decline of 12.7% in worldwide shipments to 26.7 million units in the second quarter by 2017.

In the second quarter of 2016, the worldwide PC monitor market also saw more than 30 million units being shipped, with HP and LG Electronics reporting solid year-over-year growth.

HP saw 4 million units shipped, resulting in 13% share with a year-over-year increase of 51.1%, however the vendor isn't in the top position.

Dell remains top of the leader board with its worldwide market share of 17.0%. The company saw strong growth around a number of different countries and shipped more than 5.2 million units.

For Samsung, the results weren't overly positive. The South Korean conglomerate moved down the board to fourth position, with nearly 3 million units shipped.  Overall, the vendor saw a year-over-year decline in all regions except Central - Eastern Europe and Canada.
