S2419HM, backlight bleeding

blurry and bleeding on edge screenbleeding and blurry on left and right edgesI just bought model of your monitors S2419HM UltraThin
I have some question to Dell Support here

1. The blurry and shadows edges, it it normal on this model that near all edges
there is soft dark shadow
2. Is it related to the thin bezels or is it a defect?

Monitor Settings: Factory Settings,  I do like the design thin model, but i am honestly disappointed on the image quality. The dark edges are really annoying and bring feeling cheap model. Is it all model thin bezel Dell Product (s2419HM and s2719DM have bleeding problem on edges) ? if monitor dell S2419hm return back, and has still problem bleeding, May it for money refund ?

Please help
