You are referring to the supplier of your broadband Internet connection, which comes over your cable TV wire, through your cable modem. My iMac is one of the newer (12/06) flat panel iMacs. It has a built-in screen, but can support an external screen -- a second screen -- with a resolution up to the same as the internal screen. The connection must be made through a physical wire -- a cable. I can use either a VGA wire (cable) or an HDMI wire (cable). The iMac's internal screen's resolution is 1920 x 1200. The external Dell display has the same resolution as the internal display, i.e., 1920 x 1200 = 24". But when I connected the external display through the VGA cable, the iMac could not support 1920 x 1200. So everything on the Dell display looked magnified, i.e., the resolution was less than 1920 x 1200, something equivalent to a 20" display.* When I changed the connection cable from VGA to HDMI, the Dell display happily worked at 1920 x 1200. It has a rotation pivot in its support arm. I can turn to display from landscape to portrait, and then use the iMac's System Preference Displays Pane to change the view to the correct orientation. *Full disclosure: I first used iMac Mini-HDMI to VGA converter. Then I used iMac Mini-HDMI to HDMI converter. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Roger S.
