Disappointment - perhaps it can be described as a
reaction to the most recent update MacBook Air. The laptop is not even got a new trackpad, limiting only the processor and integrated graphics. However, buyers still waiting for a pleasant surprise.
As it was established resource Ars Technica, the new MacBook Air is able to output video to an external monitor in 4K and 60 Hz. Thanks for this should graphics Intel HD 6000, which provides an output image of similar quality through DisplayPort 1.2. The previous generation of thin laptops Apple, equipped with a processor Intel Haswell, under similar conditions would provide only 30 Hz.
However, on the Apple site for maximum resolution external display 2560x1600 pixels listed. The reluctance of companies to disclose potential MacBook Air can be explained by the fact that the work of the modest hardware component in 4K resolution may not be entirely perfect. This is especially true of heavy tasks.
Used in the MacBook Air and MacBook Pro Thunderbolt connector supports 2 specification DisplayPort 1.2. Therefore, 4K resolution at 60 Hz is possible by connecting a monitor with a single cable. The same HDMI is still limited to 24 Hz at the same resolution due to the nature of specifications version 1.4. Therefore, for viewing movies in 4K resolution on a home TV MacBook Air fit perfectly.
