I see new LCD monitors with 5ms response time, and 60Hz refresh rate. What is the difference between the two? Refresh rate is the amount of frames the monitor can generate per second, and the response time is input lag or something like that?

Thanks,

Refresh rate is how many fps the screen can display. I don't quite know about response time though. I believe it's how long the picture takes to show up on the screen.

Actually the Refresh rate is how often (in Hz) the screen refreshes the display (or "is the number of times in a second that a display hardware draws the data"). A higher refresh rate means less screen flicker and less eyestrain as a result. This is completely different from FPS. Good thing LCD's don't suffer from screen flicker.

Response time is how quickly the display can have a LCD pixel to change from fully active (white) to fully inactive (black), then back to fully active again. A lower response time typically means less ghosting of the image and better picture quality. However this is best done by actually seeing the display in action. Some 5ms Displays ghost like a 10ms display. It all depends on the manufacturer (and how truly honest they are.).

Refresh rate is the maximum amount of times the screen will attempt to update per second. Response time is the delay from when the screen receives the signal and fully switches the pixels to display the image.

Boom - Enough explained here! smile.gif

@OP - if you're wondering what you should look for in a monitor in reference to refresh rate and response times, just go for the monitor that you like best. 5ms response times are common and most aren't bad ghosters. Find one that exhibits the best color in the light you'll be using/playing on it! thumb.gif

Neg. That and input lag is much more of a factor than response times below 10ms. The panel is the factor in picture quality, not response time.

True. Which is why I said typically. In true reality, one shouldn't look at specs, but at the actual physical display picture in person to determine their purchase.thumb.gif
