Apple on Thursday revealed the “next step” in Retina display technology by packing what it calls the “world’s highest resolution display” into its popular all-in-one desktop.
The all-new iMac with Retina display boasts a 5,120-by-2,880 pixel resolution with a total of 14.7 million pixels crammed into a 27-inch panel, which Apple calls “Retina 5K display.”
Compared to a 4K display, Retina 5K has 67 percent more pixels, or seven times the pixels of a normal HD display. The pixel-dense panel is shoehorned into a chassis that is only 5mm thick at its thinnest edge.
Apple needed to invent new technologies to achieve the super high resolution pixel densities in a small package, include oxide TFT, Organic Passivation to reduce cross-talk, new power-efficient LED backlight modules and a completely new timing controller. Despite the new graphics, the new iMac is 30 percent more energy efficient than the previous version.
The new iMac starts shipping today starting at $2,499 with a 3.5 GHz Intel Core i5 processor and Radeon 290X graphics chip, both of which can be upgraded to more powerful components.
