Applications such as games and video editing suffer more with an input lag higher. Learn how to minimize the problem.
At the time of purchase of an LCD monitor is extremely important to check the information in the box and manual equipment, such as brightness, contrast ratio, response time and resolution. And even with all this in mind, a prominent factor is left out: the entry delay-time that a monitor does it take to receive the signal generated by other devices such as keyboard, mouse and joystick (and if you often play on the PC, you know exactly what we’re talking about).
Why this occurs? The LCD or plasma screens do take time to process the image in order to improve the quality that is displayed. Those who use or monitor (or even an HDTV) for general work, surf the web or watch TV or movies, this lag (input lag) will be negligible. And any delay greater than if you know it, it is likely that he obtained wireless keyboard or mouse.
Now, if you use the monitor in activities that require precision in time (such as games and video editing), you might want to test your configuration. A video on Youtube called LCD Delay help understand how this delay affects performance.
In the video, a monitor and a LCD monitor are installed on the same PC side by side running the same graphical application. It is clear the difference of time to process the image on both monitors.
To do a test of this nature is necessary to have a video cable splitter, found in specialty stores. But this procedure requires an additional expense with a cable that probably will no longer be used.
An alternative to this is to do a simple test, simply based on your own reflection with the mouse. The site HumanBenchmark.com offers a test in which the user must click on the screen at the moment it changes color.
Try a few times and, if you notice any significant difference between the results (30 milliseconds or more) in different configurations, one of them is probably overdue.
The input lag is more easily noticed by players in games that you understand when the game does not respond as expected. Games that rely heavily on that time may have their effects changed. We can cite as examples, Rock Band and Guitar Hero.
How to Reduce Lag Time
One thing is certain: all LCD screens offer some degree of input lag. So, what we need to do is find ways to diminur the time to the point that our vision is not able to percebêr him.
First, check if your TV or monitor has the game mode configuration. Basically, it shuts down the image post-processing routines-you will lose a little of the quality of the image displayed.
Next, turn off other video processing options. Each manufacturer identifies its characteristics with different acronyms, like DRE or 3DNR.
If you use the HDMI or DVI input, try go back to VGA. As the VGA signal is simpler, there will be no post-processing of image as high-definition entries.
Adjustments of this kind affect the final quality of the image, but not to be so significant.
