This is an ACER 21.5" 1080p LCD monitor with 60Hz refresh rate. In superclean condition comes complete with all accessories in original retail box. Features a fast response time and good viewing angles. Comes with power cable/block and a wide variety video card conections including VGA-D-Sub, HDMI, DVI-D and DisplayPort (not all pictured). No Bad Pixels! I have been using this to test motherboards and video cards for many years without any problems. Type fonts are very clear on this monitor so great for gaming, internet browsing and word doc creation.
