Dell's ambitious $4999 4K 120Hz OLED display canceled

Noooo. Dell has canceled what could've been the best monitor ever made, its unreleased UP3017Q - a 30-inch 4K OLED display with a 120Hz refresh rate.

Dell's now canceled UP3017Q was due in March 2016, but was pushed to July, and then said to be coming "soon". French outlet Les Numeriques said that Dell officials confirmed at CES 2017 that the UP3017Q was indeed canceled. But why?

The shift was said to be around image quality problems, with color drift even when the Dell UP3017Q was viewed off-center. The company worked on these issues for months, but couldn't fix them, ultimately canceling the monitor of my dreams.
