I bought an Insignia 46" Model: NS-L46X-10A. I have a media server that im connecting directlyto the TV. so im essentaly making my TV into a big monitor. In my media center, i installed a HIS H545H1G Radeon HD 5450 graphics card. this card supports 1080p. im using windows 7 64-bit. i installed all of the drivers for the video card. The best output i can get is 1080i. Has anyone heard of and problems with my TV and video card? i cant seem to find anything.
