A Little About the Input Lag of the LG W2363D 120Hz LCD Monitor

June 27th, 2010 · 24 Comments · Other S3D Tech

I have been testing for some time already the 23-inch LG W2363D 120Hz LCD monitor, of course focusing mostly on its performance in stereo 3D mode. A more detailed review of the display is coming soon, but meanwhile I’m going to share with you some important information regarding the input lag that the LG has or actually doesn’t have. The input lag of a display does not directly influence the quality of the image you get or create issues when playing in stereo 3D mode, but the presence of input lag is not desired by gamers, because it leads to slower reaction time and thus may lead to worse results in more competitive and especially multiplayer games.

Unfortunately I was not able to get a Acer GD245HQ/GD235HZ monitor to compare directly with the LG W2363D, so I did the comparison with the Samsung 2233RZ instead, but as I’ve already compared the Samsung 2233RZ and ViewSonic VX2268WM and found they both have the same input lag, and that input lag is almost identical to that of a good CRT display (meaning input lag of less than 1 ms if there is any at all). On the other hand the Acer GD245HQ/GD235HZ monitor has between zero to about 15-16 ms input lag delay compared to the ViewSonic and all this can help a lot in judging the results I got from the LG below, so pay good attention…

The LG W2363D monitor has a special mode called THRU Mode that has the sole purpose to eliminate any input lag when activated, but before trying if that mode really works and if it does – how well it performs I’ve tried the input lag without it being enabled. The minimum input lag I’ve managed to get with the THRU Mode disabled was 9 milliseconds delay as compared to the Samsung monitor.

And after taking a long series of photos with an exposure time of 1/1000th of a second and high ISO setting the maximum input lag I was able to measure was about 18 seconds. Have in mind that these tests are performed with the use of a DVI splitter cable instead of connecting the two monitors to the two outputs of the video card and using a clone mode as my tests confirm that using the clone mode does not provide accurate results as compared to using a single monitor output with a splitter cable. So far these results can be considered worse than what I’ve managed to get from the Acer, so lets see how the THRU Mode on the LG works and will it be able to do some wonders in getting rid of the input lag…

Enabling the THRU Mode on the LG completely eliminates the the input lag on the LG, bringing it down to exactly the same results the Samsung is showing. So the THRU Mode on the LG does exactly what it is supposed to do – eliminate the input lag completely, but you need to enable that mode in order to have no input lag as some people will most likely forget to do so every time they need it. So you should enable it right from the start and forget about switching it off again…

The good news is that whenever you switch to 3D mode the THRU Mode is automatically being enabled and you are unable to switch it off until you are back to normal mode again, so there is no input lag while playing in stereo 3D mode and that is a good advantage for the LG. And there is another advantage of the LG that you’ve probably already noticed in the photos above and that is the higher brightness of the LG (400 cd/m2) compared to that of the Samsung (300 cd/m2).

MTBS-TV Episode: Stereoscopic 3D Gaming History, Part III

February 15th, 2010 · No Comments · Other S3D Tech

Neil Schneider from MTBS started telling the histtory of the stereoscopic 3D gaming in the form of a YouTube 3D video, then in the second part of that video he continued with more recent development around S3D gaming. This time, in the third part, Neil is talking about what happened in the last two years – things like Zalman Trimon 3D monitors being launched with Nvidia stereoscopic 3D drivers, updated only to work with this monitor. iZ3D and DDD extending their driver support for additional hardware, but they still did not offer shutter glasses support. Then Nvidia demonstrating their new 3D Vision shutter glasses along with a 120Hz LCD monitors and new 3D drivers. And at the end he also mentions that other companies are already working on alternatives like for example Bit Cauldron’s upcoming shutter glasses.

And don’t forget to visit MTBS if you haven’t done so yet…
