Does slow respone time affect screen tearing?

[kinsonapril]

I have got my new 2007WFP, and I am using it to play xbo360, the game Blue Dragon.
But I encounter serious screen tearing during the game...

My question is, does it related to the 16ms respone time of the 2007WFP? I mean, does respone time affect screen tearing?

I heard that something about tearing in the dell forum:

if your screen is refreshing at a higher rate then your FPS. To illustrate this phenomenon: lets say that your screen is refreshing at 100Hz and the average FSP of a game your playing is 70. Then the monitor will display some frames that are not fully rendered. For example, the screen goes to refresh and the new frame is only 50% rendered, the frame that is displayed is 50% of the old frame and 50% of the new. This is commonly referred to as tearing.

Is that correct? thx a lot

Actually, what I want to know is:

If there are 2 different montior, while playing the same game with same input source, is it possible to have one monitor having screen tearing but another one not?

Because it seems some people are not having the tearing problem on that game(at least they said NO)... I wonder if it is the matter of different monitor ><! I just got the 2007WFP for 2days...
(I have try it on my LCD TV, screen tearing also happens...)

Does it related to the ability of graphic process of the xbox360 as well?

Actually, how does screen tearing happens?

thx to all.

No, the response time doesn't affect tearing. The refresh rate does. The explanation you posted is correct. Tearing happens when the screen refreshes while a frame is being drawn, so you see part of the new frame and part of the old frame.

You can eliminate tearing by enabling vsync, but that can't be done with external devices like the Xbox 360.

Tearing happens on all monitors. Some people just aren't bothered enough by it to notice. It's not as noticeable at higher refresh rates since more frames are being drawn, but that's not really an option on most LCD monitors.

ToastyX , thanks so much.
I was worried about the tearing is caused by my lovely 2007WFP~!!

By the way, why the game developer doesn't enable the v-sync while making the game? Is there any difficulties for them to do that?

And, simply saying, if tearing occur, does it means the game is having a very low frame rate due to too much texture need to be drawn in one time?

Thanks again

Most often it's the other way around. Having a higher fps number than your refresh rate is the normal case, that's why people turn it off.

That makes me confuse... if the explaination I quoted was correct... does it means, tearing can occur in both higher and lower frame rate?

that explaination is saying the monitor refreshes and display a frame which is not totally drawn.

So, what you are trying to say is, the game is rendering a frame that the monitor can't display it in one refresh and the remain part is going to display after the next refresh?

Am I getting your point? Thx~!

I just went to the wikipedia, and I found some strange things... it said:

The faster the monitor's response time, the less page tearing, the higher the monitor's refresh rate, and the higher the frame rate.
