Response Time

One of the most interesting features of the Flatron W2363D is Thru Mode which is meant to eliminate the input lag (the difference between the moment the frame is received from the graphics card and the moment of its output to the screen). Of course, I checked this feature out to see how it works.

Compared to a monitor that has no input lag, the W2363D has a lag of about 16 milliseconds with Thru Mode off and 0 milliseconds with Thru Mode on. Thus, this feature really works even though I doubt its practical usefulness. It is impossible to spot the 16ms lag with a naked eye. By the way, the lag was the same at a refresh rate of 60 Hz as well as 120 Hz.

Quite unexpectedly, the monitor’s response time is 11.2 milliseconds (GtG) at 60 Hz. There is no trace of response time compensation here.

Switching to 120 Hz doesn’t change the overall picture quantitatively: the response time is 7.2 milliseconds (GtG) but there are still no traces of response time compensation such as RTC misses.

However, if we compare the diagrams and numbers to those of TN-based monitors with no RTC, for example with those of the Acer GD245HQ with the OD option turned off, we can see that the Flatron W2363D is quite fast. This makes me suspect that this monitor has RTC but it is set up in a non-aggressive way. As a result, the W2363D is faster than typical 5ms models but has no RTC-provoked artifacts.

But what about 3D mode when the monitor has to be as fast as 6 milliseconds or better? Unfortunately, my testbed can only work with 2D mode and cannot measure a monitor’s responsiveness in 3D mode. I suspect that the W2363D switches to a more aggressive RTC setup then because the image doubling effect was just as conspicuous with it as with competing monitors. And this effect is determined by the speed of the matrix.


The LG Flatron W2363D is not an exceptional monitor. Its exterior design is no different from its competitors and its color accuracy is not without drawbacks. The extra features like Thru Mode and Tru-Light are nothing more than trifles to play with on the first day after the purchase.

On the other hand, this monitor is quite a good option for people who want to enjoy stereoscopic imaging at resolutions higher than 1680x1050. It is free from serious defects and delivers good image quality in both 3D and 2D mode.
