If you can notice it depends on how well the display was designed. The issue is that when manufacturers give a single "response time" measurement, it's a totally bogus number that basically has no basis in reality.
What you want is for every possible gray level transition of the LCD pixel to be a low response time, and for them all be about the same response time. You could have a "6.5ms" set where many gray level transitions can take absurdly long (many times longer) meaning they'll be in transition for multiple frames, or one where the transitions take a significantly different amount of time which causes weird color artifacts on fast moving objects. At least in PC monitors, 99% of them have these issues.
The problem is I've not seen any HDTV reviewer go to the anal level of detail that you can find in PC LCD reviews. Tom's Hardware, for example, measures and graphs all those transition times. Here's an example of why the numbers manufacturers give you for response time are completely bogus - this is the curve for Sony's 16ms PC/TV monitor hybrid (fix the domain name, forum won't let me post the link right):
Note that it peaks at 80ms! That's over 3 frames where the pixel isn't right.
A good PC LCD to compare with re ghosting is the VX-922, which is absurdly fast - the fastest LCD you could buy at least last I checked earlier this year. I can't see any ghosting at all, nor color artifacts, and I'm extremely sensitive to it. It'd be nice to see someone do that kind of anal level of reviewing to find out which is best in this regard.
