Is this a 120hz monitor?

If not what is the best for $240 or less...

Analog Signal Frequency: 30 ~ 83kHz(H)/ 55 ~ 76 Hz(V)
Digital Signal Frequency: 30 ~ 83kHz(H)/ 55 ~ 76 Hz(V)
This is said on the amazon link, I think it has something to do with it
Also please give me proof or explanation because i don't want to mess up. I am buying a very expensive gaming pc with a gtx 680



Answer
The importance of 120Hz comes into play when we are dealing with film-shot material rather than video-shot material, keeping in mind that film is 24fps and video is 30fps or sometimes 60fps. A 60Hz display refreshes it's image 60 times per second and 120Hz doubles that. For video, there is no problem displaying a smooth image on a 60Hz display because the number of video frames will divide evenly into the display rate. But when using film material that is 24fps, the frame rate will not divide evenly into the 60 frame display rate, so the 3:2 pulldown technique is put into play. This means that for every 3 video frames that display once, there is a single video frame that is displayed twice. This allows an even frame rate to be divided into an odd-numbered display rate. This 3:2 causes artifacts, such as blurriness or choppy frames during fast motion.

Now, the 120Hz display rate can be divided evenly by both film's 24fps as well as video's 30fps or 60fps, thus eliminating the need for the 3:2 pulldown math. But keep in mind that video-shot material will look good on both a 60Hz and a 120Hz display, especially HD video. Film-based material won't look as good on a 60Hz display as a 120Hz display because of the need for the 3:2 pulldown. As far as standard-def material, this will look crummy regardless of the display rate.

Basically what I'm saying is, you probably do not need to get a 120hz monitor specifically for your gaming PC, just because it's a gaming PC. I'm personally using a $4000 PC with a 30" monitor and that monitor is 60HZ, and it runs significantly better than a 120HZ monitor I had earlier. If you are set on getting a 120HZ monitor because you are a gamer and want the best monitor for fast action gaming (ie. FPS games), then aim for <5ms input lag and <2ms response rate.

That screen you linked is 120HZ with the recommended input lag and response rate above, so if you're set on that, go ahead and buy it by all means.

Are 120hz computer monitors good for gaming?

I'm considering purchasing a second monitor for general usage as well as for having a second monitor while running fullscreen games, and I'm considering getting a nice 120hz monitor.

I am interested in Nvidia 3D Vision glasses, but that's a different story. A 120hz monitor is required for that so I'll need the monitor is I'm going to go for the 3D business.

Anyway - what are the advantages of 120hz in PC gaming?
I have a 120hz TV and it's pretty nice for movies and just regular television, but how is it for PC games?

And what about frames per second? With a 60hz monitor, vsync clamps framerate to 60fps to prevent tearing, if I have a 120hz monitor do I need to maintain a framerate of 120fps? Because I have a fine card, but I can't say it holds 120fps all the time. Is this a problem?

Basically, what should I know about 120hz computer monitors and dual-monitor setups?



Answer
Yes they are.

First thing, you'll be able to disable vsync altogether. Vertical tearing only occurs when your frame rate exceeds the refresh rate of your LCD monitor. Its unlikely that you will ever go over 120 fps in any modern games, so its unlikely that you will ever see vertical tearing again.

And for gaming, a 120hz screen is amazing. Very smooth, makes gaming easier, and frankly, it will just look better. Its tough to describe until you try one, but what I can say is that it did give me a noticeable edge in multiplayer games.
