The faster the display screen refresh, the less visible is the sample-and-hold blur. It's already true that 120Hz has very little sample-and-hold blur left, but I find that most often I can pick out the difference between 120Hz and 240Hz screens on several manufacturers HDTVs. I have observed the Sony 480Hz and 960Hz displays, but I cannot actually see any benefit of faster refresh there.
What I have observed is that the faster displays seem to have other high-end features that seem to be interesting. Reduced crosstalk in 3D mode is one of these. Extra fine resolution scaling is another. Effective local dimming is also common. These benefits do not necessarily derive from faster screen refresh, rather it seems to be the case that the faster screen refresh is one feature of a high-end HDTV.
I tend to look for display image quality first, and other HDTV features are a lower priority. I don't particularly care how many online services can be accessed or whether I can play video off a USB stick. But all the high-end LCDs you see seem to have lots of features, and you don't really get the choice to just get a monitor type display without such features, even though that would make high-end display quality more affordable.
