There's all the difference in the world between CRT refresh rate and LCD screen updates. A CRT has a single moving spot refreshing the raster, and the phosphor decay is typically such that the screen is nearly dark before the beam refreshes it again. 60 Hz refresh on a CRT is painful to watch, though YMMV, as Howard says. 60 Hz updates on an LCD involve no flicker whatsoever, as the pixels remain at a constant brightness until the next time they're instructed to go to a different value.
The article I read wasn't about gaming or fluid movement. It was about programers using a very high resolution monitor to display massive amounts of data, data that isn't moving in a fluid fashion. What you'll see on such a display is that your cursor doesn't move fluidly, rather it leaves a trail of cursor images as you move around the screen. For me, this would be the big 'if' - does it make it more difficult to zero in on a button to click it? The faster the refresh, the more fluid the cursor will appear to the eye. For any purpose other than programming, a 30 Hz display update would be unacceptable. In a programming environment, I imagine it's a big win. Curt On Mon, Jan 13, 2014 at 4:23 PM, John F.
