Hello, I recently upgraded to Bell HD programming and have my HD receiver connected to my 1080p tv via component cables(red,green,blue). While watching HD channels such as TSNHD(ch 1400) I receive a resolution of 480p as compared to the standard 480i. I am curious if the resolution is limited to 480p by the component cables and if a HDMI connection would bump this up to 720p/1080i? This being said I know that component cables CAN send 720p signals because my PS3 is connected via said cables. Any help would be greatly appreciated! Thank you.
