ViewSonic shows off 22-inch 120Hz LCD monitor at NVISION 08

And how do you know that?

An easy way to test if it is really 120fps is frame tearing. If it is operating at 120fps, it would be able to display fluid motion all the way to 120fps without experiencing any frame tearing. So get a game where you can put a frame cap on, and set it at like 110 or 115 fps, and move the mouse around really fast and see if there is frame tearing. If there is, it is not 120Hz.

Sorry this is completely wrong. Tearing has nothing to do with the FPS. It has to do with what is in the front buffer when the monitor refreshes. So you'll get tearing no matter what the refresh rate is unless you have v-sync on.

In fact you'll get twice as much tearing with 120Hz because there are twice the number of refreshes, unlinked from the backbuffer presents. But the fact is each refresh displays for less time so it might end up harder to see.

By the way, it's not 120fps, it's 120Hz... 120 refreshes. It is *not* linked to frames in any way.
