Much has been said about 4K technology lately, technology that certain audiovisual work programs boast about, or without going any further, various audiovisual providers (like Netflix) already announces that it will soon broadcast TV shows and series in 4K. Apple for its part has provided its latest Mac's with outputs for 4K screens e they are even marketing some third party displays in 4K.
It is a technology that does not stop developing, 4K is the visual quality closest to the quality of celluloid to give you an idea. Well it seems that working in 4K with Mavericks, and the latest MacBook Pro with retina display, it only works at 30Hz, if we want to reach 60Hz the screen would deform, something that does not seem to happen in Windows ...
If we want send signal to a 4K screen at 30Hz we will be sending about 8Gbps of data through a 10Gbps Thunderbolt. The 60Hz requires a Thunderbolt 2, which with its two transfer channels can transmit two signals of 1920 x 2160px alternating pixels.
Something that is complex to understand but it will undoubtedly be fixed with a driver update in Mavericks, since Windows 8.1 is capable of working at 60Hz with the latest Nvidia driver update.
Really to the naked eye there is not a big difference working at 30Hz compared to 60Hz, speaking of a simple use of the machine, but it is true that If you are gamers, or you work in the audiovisual world (or if you want all the definition of a 4K screen) you will have to wait for the drivers to be updated or go to the dark side of Windows 8 ...
