One of the most important novelties this year has perhaps been the irruption in the market of the first commercial monitors with 4K resolutions, that is, an average of 4 times more definition than the already classic Full HD monitors and televisions.
Now that Thunderbolt 2 is making its way into the new Macs that are appearing with ability to output video at this resolution On an external monitor, Apple has been quick to include a Sharp 32 ″ 4K compatible monitor as an option even though the price is still quite restrictive.
However, not everything is positive in the appearance of 4k on Mac and it is that Apple's flagship seems that there is still not everything optimized at the software level It would be desirable to adequately support these types of resolutions with certain monitors.
The Anandtech website has carried out a full equipment analysis in which both the aforementioned Sharp monitor and a 24 ″ Dell Ultrasharp have been tested, concluding that although at HiDPI resolution at 3840 × 2160 the video quality was overwhelming and the detail was very good when scaling sources and adapting the resolution made everything look more blurry than what might be considered acceptable.
I am disappointed that Apple does not allow any HiDPI mode on the Sharp screen. While 3840 x 2160 seems like a great resolution for video work on the one hand, for everything else, even on-screen menus and text look too small. I'd love to see a 2560 x 1440 HiDPI option but it looks like I'm going to have to wait for Apple's own display before this is achieved.
