Review on Viotek 109013NH: Ultra Thin G Sync Compatible Zero Tolerance 23.6" Monitor with 1920X1080 Resolution, 144Hz Refresh Rate, Anti-Glare Coating, Frameless Design, and Wall Mountable Capability. by Trevor Lawler

Overall this is a great monitor but after 3 years of use I noticed flickering horizontal lines at the bottom and sometimes at the top of the monitor. This also results in a halo. I fixed this issue by setting the frequency to 120Hz instead of the full 144. I'm not an absolute fan of FPS graphics, so I don't mind it, but for people who are, I suggest getting a 4-year warranty (if you have one). is a). ) in case something goes wrong.
