Replaced 6 Dell monitors from 24" to 30" with 6 Lenovo monitors from 28" to 32" with DisplayPort and HDMI and couldn't be happier. The Dells were old and very hot, operating almost at room temperature. Colors are vibrant, response time is twice as fast as the Dells (there were old ones). UNIFORM color and brightness with screen adjustment that makes sense unlike almost every other monitor I've bought. The price is negotiable. Would buy again without hesitation.
