Cant get full screen tv display on dell xps one 2710

January 2, 2013 1:03:00 AM

I have a Dell XPS One 2710 with TV tuner in it, purchased about 10/12/12. I can’t get a full screen display watching TV. Regular display is fine. The TV display shows as a 19 inch diagonal inset. It is connected via coax from the set-top box (Cisco ISB7000) supplied by Hawaiian Telcom to the tuner card. Using Media Center’s auto setup fails. Manual setup does not find any Cisco in its 300+ boxes listed. Hawaiian Telcom, the TV service provider, had no one capable to deal with the problem and sent a Supergeek tech at their expense. He did get a display going but it only shows the 19” inset. I think he tried some of the boxes in the Media Center list till he found something compatible enough to get the display. He was not able to get a full 27” display.
