Was there ever any attention given to this monitor's refresh rate? It has a refresh rate of 16ms. Isn't that a poor refresh rate?

Ah, I believe that translates to 60Hz, a standard refresh rate for all LCDs.

If you include the infamous black-frame-insertion technology, then it's reportedly 120Hz, but really you're only still seeing 60 true frames of color changing per second. Or something like that. =P

I think you mean response time, not refresh rate.

What's the difference? I'm a huge nub, I know!

Response time = time it takes for a white pixel to go black, or sometimes a gray pixel to go black (depends on the latest standards).

Frame rate / refresh rate = how many times per second the image on the screen is redrawn. LCD standard rate is 60 Hz / Hertz = times per second.

Refresh rate on LCDs are a completely different animal than on CRTs anyways. I always laugh at those who complain about "only 60hz refresh rate" on LCDs.

On a CRT, the refresh rate actually means something: The picture is drawn and re-drawn x times a second (well, not technically correct: the phosphor particles are shot at x times a second, making them light up and dim again; but let's not get too technical), fooling your eye to have a constant picture. In practice, however, the picture is not constant at all, it flickers on and off. A 60hz refresh rate means that the picture goes on and off 60 times per second, making it appear that the picture is unsteady. If the monitor has 120hz refresh rate, the eyes are fooled enough to see a constant picture without flicker.

A LCD works differently. A LCD actually DOES have a constant picture (again, not quite correct; anyways, it does not use phosphor that dims easily) and does NOT flicker on and off all the time. A solid color on a LCD will stay solid until you do something with it, e.g. in a game. When you move a character in a game and the background never changes, then the LCD won't "turn off and on" those pixels that don't change, they simply stay lit. The only thing that changes on such a screen would be the pixels of the character.
