As far as the lack of a HDMI port goes , when a monotor does not ave built in speakers there is no need for a HDMI connection and a DVI is the same thing but without the sound.
When you start looking at monitors for $100 or less then you really can't expect much and the ons year warranty is an indication of the kind of quality. If you do get this monitor make sure it's running perfect because you don't want top be left stuck later on when the warranty expires.
