Ma siamo sicuri che i 400hz delle TV equivalgano alle frequenze di aggiornamento reali? Se non ricordo male erano calcolati in modo completamente diverso e inidicavano un'altro paramentro..per tanto le TV sono 60hz effettivamente.
A supporto di quello che dico:

Displaying a 120fps signal on a 120Hz+ television
As of 2013, there is no television officially supporting a true 120 frames per second signal as an input. Even a real 120Hz or 240Hz television does not support a source of 120fps. They can only display at that speed frames created by themselves using motion interpolation. For example, you can feed a television a 1080p @ 24Hz signal, which it will up convert to 1080p @ 120Hz internally; but you cannot feed it directly a 1080p @ 120 signal.
Although not officially supported, some people were able to hack it, either by faking the signal as being 3D or by overclocking it.
Despite the fact that the HDMI version 1.4 added support for 1080p @ 120Hz, there is no content available to display on a TV at that frame rate. Only a computer can generate this high frame rate. This will not change anytime soon. Gaming consoles are limited to only 60fps, even the PS4 and Xbox One. Movies are being shot at 24 fps. The first movie shot in 48fps is The Hobbit and it is only available at that speed in some specific theaters.
Currently, the only screens than can display a real 120fps signal are some 120Hz computer monitors on high end graphic cards.
Conclusion
For TVs, the refresh rate means nothing, especially with manufacturers inflating their numbers. A high refresh rate TV does not guarantee it to be motion blur free. Even for console gaming, there is no advantage to a 120Hz+ TV because the console video games are capped at 60 fps anyway.
For gaming on a PC though, a higher refresh rate monitor is definitely worth it if you have a strong enough graphic card.
