Review on ViewSonic VG2860MHL 4K Ergonomic Monitor with DisplayPort, HDMI, HD, LCD - ‎3840X2160P Resolution, VG2860MHL-4K by Joey Basso

These monitors are not very good. They last about 6 months before DisplayPort stops working. Their HDMI ports aren't much better (they add about 3 months to the lifespan). I bought 3 (paid 599 at the time). Viewsonic replaced all 3 in the last year but this will void the warranty. After 6 months the new ones stop working and for now they don't do anything about it. They are also extremely susceptible to static electricity. They are poorly insulated and will flicker if there is static electricity in the room.
