A tuner produces 25 or 30 fps image, while a PC does 60+, so you need faster response. Also, the ghosting on a TV signal which was captured using a rather open shutter (>180 degrees) is already in the signal as motion blur, so the little ghosts on the LCD does not matter. And the signal has about the half (in HD) or very low resolution (in SD) which is upscaled with blur. In opposite, the PC with windows and other sharp artificial image will show the real performance of the LCD panel when these objects move. (btw you will not notice blur/ghosts when watching videos on a PC either, it's not because of the tuner, it's because of the content).
