Should the MacBook Pro actually get the Retina display it would need a couple of tweaks to pull off a resolution of that kind. Intel’s Ivy Bridge chipset can handle resolutions at 4096×4096, so that’s covered.
According to MacRumors:[quote]Apple has already added new “HiDPI” modes in Lion that support this resolution-doubling mode. Apple has even added ultra-high resolution artwork in Lion with desktop images at 3200×2000 pixels and icons at 1024×1024 pixels.[/quote]
It looks like Apple’s already taking the steps necessary for implementing Retina graphics in their MacBook Pro lineup. The question remains, can a MacBook Air handle this kind of resolution? Does it have the power to drive that display density? If not, then this may be one of the key differentiating factors between the MacBook Air and the MacBook Pro lineup moving forward.
We hope — like seriously hope — that Apple doesn’t roll out Retina displays in one model and not the rest of its laptops. That would be a pretty serious bummer moving forward.
