I have an ACER Aspire 5517 notebook. It has 2 USB ports and one VGA port. My DVR hooked to my TV has a USB port in the front, and 2 in the back of it. It also has a HDMI port on the DVR. Can you tell me if I can hook the 2 of them up, and with what type of cable? Also, is there anything special I need to do in addition to see my computer screen on my TV?
