Monitors: response time (in ms) and Hz are the same thing? and if not, what's the different?

Thx for the help

No both are different things
Response time is how fast a pixel can display a change in color like from black to white or another changes of color
and Hz is the refresh rate the like@60Hz you can see the lag when seeing a car driving at faster speed or other things like football but its much more smoother in 120Hz

OK THX

They're different. Hz refers to how many times per second the image on the screen can be updated. So a 60 Hz screen can flip through 60 different frames per second. In that case, the screen will be updated to show a new picture every 16.7 milliseconds (thousandths of a second). Or in the case of a 144 Hz screen, it will be updated approximately every 6.9 milliseconds.

Response time, on the other hand, refers to how long it takes one frame to update to the next. It's the speed at which the individual pixels can transition from one color to another, although there are various ways to measure it and not all screens will necessarily go by the same standard. In modern displays, this is typically below the length of time that the frame will be shown for though. A lower response time can potentially allow for the image to appear sharper in motion, since the pixels spend less time transitioning between two colors.

Another thing that's not usually advertised in a monitor's specs is "input lag", the time it takes a signal sent from your graphics card to get displayed on the screen. Many screens will spend some time processing the image before displaying it, to do things like resizing the image, enhancing its colors, and so on. In extreme cases, this can result in a noticeable split-second delay between when you perform an action, and whether that is depicted on the screen. Keeping the input lag as low as possible can potentially provide a slight performance advantage in fast-paced competitive games, but you'll need to check in-depth reviews for measurements of this statistic.
