CIOs with loose bring-your-own-device policies might find their corporate networks clogged should employees bring the just-announced Macbook Pro computers to work. Introduced at Apple's developer conference Monday, the new Macbook Pro is fitted with a Retina display, whose resolution of 2880-by-1800 pixels packed into a 15.4-inch screen is the crispest screen for a computer yet, clearer than Apple's newest iPad.

But it may also wreak havoc on CIOs' networks and connectivity budgets because, as some analysts have suggested, owners of devices with high-resolution screens might well consume more video and HD video, which would result in higher bandwidth consumption.

Experts told CIO Journal earlier this year that employees using the new iPad, which includes a Retina display of 2048-by-1536 resolution with 3.1 million pixels, would be likely to download more video content because of the more attractive display, thus slowing enterprise networks and increasing data costs from carriers.

CIOs would thus do well to monitor network usage and make sure their employees aren't watching too much high-definition content from YouTube and other video websites. At the very least, CIOs might want to follow the lead of companies such as Google, which give employees a monthly "bill" for the IT services that they consume, and make the usage a matter of record throughout the company.

CORRECTION: An earlier version of this article incorrectly said that the higher resolution Retina displays of the new iPad and forthcoming Macbook Pro computers would increase consumption of network bandwidth, thus slowing performance of corporate networks. Higher resolution screens do not in and of themselves consume more network bandwidth. Some analysts have suggested that owners of devices with high-resolution screens will likely consume more video and HD video, which would result in higher bandwidth consumption. This article has been substantially recast to reflect this change.
