Digital Trends: ASUS Zenbook NX500 ups the ante with Quantum Dot display featuring Nanosys QDEF tech

Quantum what?
A key trait of the Zenbook’s 4K touchscreen is the use of Quantum Dots, a display technology that improves the accuracy of backlit displays with millions of tiny nano-semiconductors that emit light at specific wavelength when hit with blue light. Though similar in purpose to a traditional LCD color filter, Quantum Dots are more efficient and produce more accurate color.
In tests, the NX500 rendered 100 percent of the sRGB gamut and 96 percent of the AdobeRGB gamut. The latter figure is good enough to tie Samsung’s $2,000 U970HD 32-inch monitor for the best we’ve ever recorded. The Acer Aspire V15 Nitro Black Edition, for comparison, only hits 73 percent of AdobeRGB.
