Input Lag and Refresh Rate

post #1 of 3
Thread Starter 
What's the difference between input lag and refresh rate when it comes to choosing a good monitor?
Input lag seems to be measured in ms and refresh rate is measured in hz. I think that I do understand refresh rate a lot better then input lag (in essence, 60hz = 60 "fps" on the screen), but when it comes to input lag I'm still kind of confused.

Thanks,
My System

Refresh rate is simply how many times the display can refresh per second. Input lag is the delay between what comes out of your video card and it being shown on screen.

They aren't related.

I found this thread rather interesting. I am a huge fighting game fan in super important high level fighting games each frame loss is important, and losing a few frames is actually noticeable. These monitors were tested for Evo:

The specs like 2ms / refresh rate do not mean you won't have lag or input lag, I wish that was true.
