Samsung 28-inch 4K Display for $700
The UD590 connects to your PC via HDMI or DisplayPort, and its specs are impressive: a 1-millisecond gray-to-gray response time, 370 cd/m2 brightness, and support for one billion colors. It uses LED backlights with a TN panel that offers 170- and 160-degree viewing angles. These angles are good, though not as wide as monitors using IPS or LPS panels.
