I opened the item and displayed an image to confirm its functionality. It is a new, unused item. This 21.5-inch IPS display with Full HD resolution utilizes technology to achieve a wide 178/178-degree viewing angle, allowing you to see the screen from almost any angle. With AMD FreeSync technology and an ultra-fast response time, it delivers smooth performance at any frame rate. It is equipped with flicker-free technology to reduce eye strain and a Low Blue Mode that cuts harmful short-wavelength blue light with smart software technology.
