Hi, recently I've bought this model from a local retailer and experienced this strange oval figure in the center of the screen. In about a week I got this model replaced with exact same one, and got almost the same oval figure in the center. Photo #1 - 1st monitor and #2 - 2nd monitor. So, I am wondering, is it ok or should I replace the 2nd monitor as well? 1st monitor2nd monitor

First, turn the room light ON. Dell monitors are not validated in a full dark room. Dell Consumer monitors are inspected at 150lux ambient lighting (similar to typical office lighting). Dell UltraSharp monitors are inspected with a tighter criteria of 70lux ambient lighting (dimly lit room but not completely dark).
Second, once the room light is on, run the disconnected from PC video card AW2518HF Built-in Diagnostics (page 52) on both AW2518HF. Post pictures of the gray, red, green, blue, black, and white screens. Based on those pictures, I will tell you if these AW2518HF pass our manufacturer uniformity policy.
