Input lag or ghosting... Whats more noticeable - Page 2

post #11 of 19
Hyperion you have been told a million times, the ghosting & input lag on both the Samsung & Asus are only going to be an issue for CRT users or users switching between the Samsung and a 120hz low lag Asus or BenQ.

I'm just trying to get the opinion of those who do notice it, as to what is more annoying.

I wasn't aware you were comparing the input lag and ghosting to a CRT monitor. In that case, you're absolutely fine. Go for either one!

I don't know if you know this but response time and input lag are two different things.

http://en.wikipedia.org/wiki/Input_lag#Input_Lag_example_for_console_gaming
... lag measured by the difference between the time a signal input enter a display and the time it takes for that input to be shown on the display.
...
Display lag is not to be confused with pixel response time.

Response time is the amount of time a pixel in an LCD monitor takes to go from one value to another and back again. It is measured in milliseconds (ms). Lower numbers mean faster transitions and therefore fewer visible image artifacts.

Older monitors with long response times would create a smear or blur pattern around moving objects, making them unacceptable for moving video. Long response times can be annoying to a viewer depending on the type of data being displayed and how rapidly the image is changing or moving. Current LCD monitor models (such as those with 120Hz or 240Hz refresh rates) have improved to the point that this is only seen with extreme contrasts.

In short,
Response time = Ghosting or smearing, this issue solely depends on the display
input lag = time it takes to see input on screen. can have many factors, such as type of keyboard/mouse, drivers, background processes, system performance, display, etc...,

EDIT FOR CLARITY:
generally when people measure response time, they are measuring the signal after it has been output from the computer and passed through all the internals and processing of the monitor itself. They are measuring the time it takes for the signal to enter the panel and display a given color.

Analogy: response time
Imagine tipping a bottle of honey upside down. and measuring the time it takes for a drop of honey to hit the floor. for this example, we will not measure the time it takes for the honey to run down the side of the bottle to reach the cap, nor will we measure the amount of time it takes to bead up at the tip. We are only measuring the time it takes for the honey to fall to the ground once it is suspended in free air and no longer in contact with the bottle.

Input lag:
the time it takes from the moment you begin thinking about the bottle of honey, to the time it takes you to extend your arm to pick up the honey, tipping it over, flowing through the bottle, this timer stops once the drop of honey hits the floor.

Essentially if measured properly on a 120HZ monitor, response time under 4ms will very rarely have ghosting(generally depending on color of pixels), 4-8ms might incur mild ghosting but should really never be noticed, 8-15ms will usually have ghosting, and will be noticed during certain fast paced scenes, anything over 15ms will be very noticeable as the ghosting can last 3+ frames.

input lag is there but just take the screen that is the most basic high end.for the real world ms time ,wich was tested by a doctor in the past sony came as the best for what the doc tested.plasma is king in this field but good luck finding small one.last i checked 32 inch 1080 unit were the smallest

Ghosting affects your ability to focus on an object at high speed. How much someone finds annoying depends on their play style, mouse sensitivity (higher=faster=more blur), eyesight and previous CRT experience.

Despite having a measured input lag of 4ms and supposedly CRT like, I find my Asus vg236he far laggier than my Sony FW900. The sample and hold effect is creating an extra level of visual lag not detected by measuring equipment.

I have directly compared:

Samsung 2233rz (15ms lag, very low blur during fast motion)*
vs
Asus vg236he (4ms lag, some blur during fast motion)*

They are a virtual tie with my preference oddly going to the Samsung for gaming performance. It is easier to focus on a target and let the brain compensate for the input lag.

*By fast motion I am referring to the use of sub 15cm/360 mouse sensitivity in an fps game such as Quake. Due to confined spaces, this is far more motion than in slower paced games like BF3.
