120hz vs 60hz

As was hinted at earlier the refresh rate the monitor was designed for. This was best seen on the old CRTs where the phosphor chosen, and hence the fade of the last frame defined the refresh rate. In that old example imagine phosphors designed for 120hz, they'd need to fade very quickly and so if run at 60hz. There would be a more visible flicker. However if designed with slow fade, the previous frame wouldn't have faded enough for it not to blur into the next, and hence the benefit lost.

Sure LCD screens don't work the same but don't forget that the final display electronics will be designed with similar "fade" in the form of capacitors acting as buffers.

LCDs don't fade at all and don't share any electronics with CRT screens. The filter stays the same until given the instruction to change. How quickly they can change is the response time, which can be just as quick on a 60hz screen as a 120hz screen.

- Exactly why i didnt bother to reply, and what i've been saying all along. What will affect monitor performance for image delivery is the response time (and digital connectivity).

Yup, and what do you think defines the refresh rate?

I was using CRTs as a hopefully easy way to see example of how if the while thing isn't properly designed for a frequency then benefits will be negated. Taken literally it was not applicable in the slightest, but that wasn't the intention.

Not the response rate of the capacitors. How quickly a pixel is charged and discharged is independent of the frequency the image is rendered or refreshed. Thats why on poor quality screens, you may have a refresh rate of 60 Hz yet see blurring on fast moving images. A fast response time with the capacitors will eliminate the blurring, but a fast Hz refresh will make it more apparent. That is to say that they rely on one another but are not the same thing. With a higher hertz cycle (assuming you have a fast response time) you will see more stability in motion. But this will be barely noticeable, and has nothing to do with performance in a game (as was earlier suggested by someone). It will just appear smoother.

To sum up: As with anything, a machine is only ever as good as the sum of its parts. If one part is inferior, it lets the whole thing down.

[phil4]

And that, the sum up, I wholly agree with.

I'm buying a Dell 27" IPS monitor in the future. I believe it's over 60hz.

AFAIK they are 60 Hz.
