In early 2016 Dell announced the world's first OLED monitor, the 30" 4K Ultrasharp UP3017Q. This interesting and innovative monitor was supposed to be shipping in March 2016 for $4,999 - but that did not happen, and reports suggested that Dell canceled this monitor as the company was unhappy with the image quality of that OLED panel - especially the amount of color drift that it displayed when you viewed the monitor from the sides.
But Dell now started shipping the UP3017Q, and the price is set at $3,499, or $1,500 lower than the original price Dell announced in 2016. Hopefully other companies will follow suit to release OLED monitors as well.
The UP3017Q features a 4K resolution (3840x2160, 147 PPI), a refresh rate of 60Hz, viewing angle of 178 degrees (both vertical and horizontal) and a brightness of 300 cd/m2. The monitor supports mDP (1.2), HDMI (2) and USB type C.
