i am looking at 32 inch 120hz 1080p tvs out there to use as a pc monitor. i know the image wont be as sharp as 1920 by 1200. i am just concerned about ghosting. since it is a 120hz tv will that help? or since its connected to a video card, will it only display 60hz? thanks guys!
120Hz PC monitors and 120Hz HDTV work differently.
The electronics of a 120Hz HDTVs create an interpolated frame in between every two actual frames it receives (at 60Hz) to improve smoothness and gives movies that "live" look; kinda like a talk show or news program.
The creation of the interpolated frame will take time, thus it will increase input lag.
