Video card dependency

[Macko112]

I'm starting to get into the home theatre world and have been doing some research. However, there's one concept I can't wrap my head around and my searches have proved futile.

A lot of people here talk about hooking up their HDTVs to their mediocre video cards. Do the inner working of the TV also help to generate the picture? Or is generation completely in the hands of the poor little video card?

It doesn't make sense to me that video cards which can't achieve constant 60fps in 1280x800 resolution video games on a PC can run a 2 hour action-packed movie at 1920x1080 resolution. Could anyone clear this up or help me see what I'm missing?

Thanks.

PC video cards CREATE the video for games, they have to individually render layers, fills, texture, edges, etc... whereas they only have to act as a digital to digital or digital to analog convertor for video, and may have a built-in hardware codec to do so. Video playback, game graphics and autocad graphics are three different worlds.
