Good workspace in applications, fit 27 "very well.
Nice move in the picture with 144Hz and G-Sync.
Right stylish design, stylish, fits most of the time. Relatively narrow edges.
No extreme quirks / attributes.
Cheaper than the competitors.
High gamma / brightness default.
Very bad blackness in the picture.
Poor color rendering, slightly cured image even after calibration.
The viewing angle is ok but not more.
Nvidia G-Sync sticks on the foot with superlists that leave a sticker sticker when you remove it, requiring some work to get rid of.
Good screen for FPS gaming with high demands on response. Less good for image processing, after calibration, it works helpful. The color rendering is poor at lower brightness and you want to decrease the brightness to increase the very badness. Gives it a "nja" in grades, however, I think similar models on the market suffer a bit of the same problem.
One year after purchase, I gained some artificial burn-in at the top of the screen, it appears quite clear even against bright backgrounds and is very ugly / distracting in darker backgrounds. The error covers 80% of the horizontal on the monitor and 1-3cm down from the top. Pulling down the score because of this,
Dell support has proven to be difficult to get in Sweden, linked to German pages when trying to find them. But they will have a Swedish department to see if they are willing to do something about the error. Have read about others who had the same mistake, they blame for having static images on the screen for a long time as burnt but I've always had power saving mode running. Never had a burn-in on a LED screen before.
