Screen response time?

Hi guys i have a WUXGA screen for my laptop how do i find out its response time? What i mean is TFT Monitors usually have a displayed response time 6ms,4ms etc.

 

Very good point there...i guess you would have to find you the brand of you screen 1st.....then google the specs of the screen.

 

here are the typical specs of the 17" gaming notebook LCD panels
(used for most notebook brands)

25ms? thats bad How would i find out which company made my screen? Its a dell vostro 1700

 

Yeah i get what you mean ....but then again these are notebook screens not stand alone LCD monitors.....

 

Use everest or another system information program.

And you think 25ms is bad? I think it's pretty good for a laptop.
According to a magazine, my packard bell lappy's display(lg philips) has a 35 ms response time, and i only notice it when draging a window. It doesn't bother me at all

 

do you think it has any effect in gaming? Some LCD's boost response times of 2ms. Think its just a marketing gimmick?

 

In real life less than 4ms is impossible, sorry. The cost for producing LCDs with a response time lower than 4ms is much higher.

 

Doesn't the response time differ depending on the color? A lot.

 

out of interest, how is it meaningful to worry about framerates in games on laptops above about 40fps if the screen response time is 25ms? Surely that means the maximum refresh rate of the screen is 40Hz? Am I missing something? More importantly, am I making sense?!

 

Yes you're making sense. 16ms = 1/0.016s ~ 60 Hz (62.5 actually), or 1/0.025 = 40 Hz. You won't be able to display above that rate.

If your GPU is fast enough, this is when Vsync is useful. As long as the GPU can feed your display at 40fps or faster, it'll be smooth as silk. But if it even drops to 39 fps, with vsync on, your fps will drop in half because it will have to wait extra cycles to synchronize properly.

So having 16ms or faster response is ideal because even if it drops from 60 Hz to 30 Hz then you're not noticing it so much.
