Isn't the input rate independent of the panel itself and instead dependent on the controller board and receiver?
I haven't used one yet, but BrightCandle is right. If it takes nearly as long to change a pixel to the new color as it is displayed, before changing to a new color, the color on a moving object never spends time at the correct displayed color. If you run at 60 FPS, this may not seem like a huge deal, as the frame only changes every other refresh, but as 120 FPS, a moving object is almost always the wrong color and shifting.
So a liquid crystal panel has little crystals suspended in a liquid.
The panel has to flip those crystals around, using electric fields. You could imagine that if the liquid is very thick and syrupy, you won't be able to flip the crystal fast enough, even if you pile on a ton of electric field. Or, you'd need enough electric field that it would damage the crystals.
So even if you swap out the controller for a panel, the panel itself might inherently be unable to support really high frames per second. For example, the panel might rely on the crystal passively aligning one way, and using an active field to align another. So you can't increase the passive part of that.
then why does a 120hz ips panel have a noticeable, positive difference in gaming compared to running it at 60hz? i won't pretend to understand how the panel technology works, because i don't. however, i've seen the difference first hand.

To an extent that is correct. The frame rate is mostly dependent on the monitors controller. But just putting 120hz controller isn't sufficient to make any panel respond well. If the LCDs can't switch fast enough then 120Hz is going to be very blurry, as each frame merges into the next.
Clearly the Korean panel makers have put overclockable controllers into their IPS panels and shown that sometimes you can get the controller at least to perform better, but the panels don't all respond all that well to this.
No, not all panels can handle a 120Hz refresh rate. There is two ways of getting 120Hz on an LCD.
1: The panel actually supports refreshing its pixels at that rate. This is what the more expensive displays typically do.
2: The panel uses a backlight that cycles from top to bottom (typically referred to as a Scanning back light). This gives the affects of having a higher refresh rate without actually flipping the pixels that fast. So a cheaper panel can be used, but gives the same affect of of a 120Hz display. This does result in a dimmer display in some cases.
But yes mate you know more about it that I, but the big problem is (this is real hard in english for me), that you expect the concept refresh to be the same for ips and lcd, but it's not. I did not invent this madness someone else did. So you cannot compare.
It's not just that it's more..
Ips is not lcd end.
Okay I' sorry it ended like that and maybe you got me wrong.
That does not make it true what you said tho.
