We ordered a renewed tower since we wanted a home PC, but really do not use it often. What we ordered was advertised as having an HDMI interface. We received one with a display port instead. Thankfully the seller included an adapter. The tower had a VGA interface as well as 4 different display ports. We tried but could not get any of them to work. According to their correspondence, the seller did not feel this was possible as every unit is tested. We connect to a newer model TV with an HDMI interface. This worked with our 12 year old HP, works with my daughters newer laptops, but simply would not connect to the unit we received. I tried to save a few dollars and took a gamble with a renewed product and seem to have lost this round.
