I brought the insignia 40 led tv 1080p/60Hz
When I hook it up it reads 720 in the upper right hand corner where is the 1080 I supposed to have brought
It depends on the source, if your cable box, bluray player, etc, is set to output 720p, then that is what your TV will display. You'll have to go inside their setting menu and adjust the output to 1080p.
