Here’s a surprise feature that Apple hasn’t advertised: the new MacBook Air models, which were refreshed during the company’s “Spring Forward” event a few weeks back, support 4K displays… with some caveats.

The support was recently revealed by Ars Technica, which notes that Apple’s site actually only says the computer supports displays with resolutions up to 2560×1600 pixels.

The site believed Apple’s computers actually supported higher-res displays, however, so it put its hypothesis to the test and found that the 2015 MacBook Air does indeed work with a 4K display without a hitch, even though Apple isn’t advertising the feature.

“The short answer is that yes, both the Pros and Airs now support 4K output at 60Hz using a single DisplayPort 1.2 cable,” Ars Technica explained, noting that support comes in the form of Intel’s Broadwell-U processor and integrated graphics.

There are a few caveats, however. The news outlet says you won’t want to play games and that framerates start to drop below acceptable levels even when running apps in full-screen mode.

That might explain why Apple doesn’t advertise the feature – since it doesn’t work flawlessly in all situations – but it’s still a neat bonus if you happen to pick up a 2015 MacBook Air.
