The Acer H Series Widescreen HD LED Monitor with VGA & DVI Inputs is an LED-backlit display with a 1280 x 1024 high definition resolution and a 5ms video response time. LED-backlit means that LED lamps are used for light as opposed to traditional CCFL lamps. LED lamps are longer lasting than CCFLs and consume less power. The 1280 x 1024 resolution will display images in fine detail and the fairly fast 5ms response time will play those images smoothly, without dropping pixels in the process as can be expected with slower response times. Inputs consist of VGA and DVI, and a cable is included for each.Features: Display Type: Widescreen Full HD TN Panel LCD, 3D Ready Display Area: 21.5 Display Colors: 16.7 Million Brightness: 400 cd/m2 Contrast Ratio: 70,000:1 Viewing Angle (H/V): 170Âdeg;/170Âdeg; Response Time: 3 ms Max Resolution: 1920 x 1080
