By Acer's measurements, the S231HLbid 23-inch LED monitor has much higher dynamic contrast ratio than most LED monitors; that is, deeper blacks and whiter whites. (Contrast ratios are debatable in meaning across manufacturers and models, but the picture quality does consistently receive praise in user reviews.) It has VGA, DVI, and HDMI for Full HD 1080p viewing and gaming needs. The slim design fits any office desk, even that of a messy graphics designer. Energy Star 5 compliant and uses 68% lower power consumption To top it off nicely, a new model comes with a 3-year limited warranty for parts and labor. HDMI cable is conveniently included in the box.
