This refurbished computer was advertised as having HDMI and WI-FI.  What they DO NOT communicate - is that the to make the HDMI work- you have to use the supplied adaptor (converts display port to HDMI)The wi-fi is also not built in card but rather a USB  thumb drive that acts as a wi-fi adapter.The adapter works but the monitor "flashes" on/off like there is a short in the display port or the HDMI converter.  I think the description should be MORE CLEAR so that customers are not left surprised
