Acer gaming monitor, 23.8-inch size. Its specifications are FHD 1920+1090 with excellent FreeSync technology, AMD, 180 frames, and 1 millisecond (VRB). Note: The monitor has been with me for three years, used for two years, and it is clean and working (its plug is American). Note: The monitor has no sound unless headphones are worn. It has been like this since I bought it, I think because it's a gaming monitor.
