And how is the situation with the input lag on Samsung 2233RZ and ViewSonic VX2268wm… So if a display has absolutely no input lag this means that you get no disadvantage of actually seeing things with some delay and you’ll be able to react faster. And here we are talking about fractions of a second or milliseconds, but even 1 ms can be vital to winning or to cost you your life in some very fast paced FPS games like Counter Strike or Quake Live for instance. You probably guessed already that I’m talking about input lag or the time that the video signal coming out of the video card needs in order to be processed by the electronics of the display, before it can be visualized on the screen. There was one thing that I needed to be certain of, because it might be vital for some gamers playing in 2D mode (especially in FPS games) and even for the people using these displays with 3D Vision to play in stereoscopic 3D mode. Both displays have some differences in design and functionality and although they both use the same LCD TFT panel they do differ in the results they provide. So if you consider replacing your gaming CRT monitor you should definitely go for a 120Hz LCD, especially if you also consider using this display together with 3D Vision for viewing stereoscopic 3D content.įinally I was able to get a hold of a 120Hz ViewSonic VX2268wm monitor for testing and of course to be able to compare it to the already available Samsung 2233RZ I’ve had for quite some time. But anyway to answer the question if a 120Hz LCD display is a good alternative to a good CRT display I can already say they perform as close as possible in the critical areas like input lag or the lack of such, but the LCD also has some clear advantages over the CRT technologies.

Now I’m talking about a very minor input lag and by that I mean something like 1 or 2 milliseconds at most, but then again we can also consider that the “ghosting” of the numbers on the LCD can also be caused by the slower response time of the pixels – taking pictures at 1/1000th of a second while the response time of the pixels is at 3-5/1000thof a second. At first look the numbers on the counter look the same on both displays, which is good, but the second and more detailed look reveals the fact that the millisecond counter on the LCD does not show absolutely clear numbers as on the CRT.Īs a result of this test I can conclude that in fact there is a very little input lag on the 120Hz LCDs like ViewSonic VX2268wm compared on what you get on a good CRT display, but still there is some, even if it is very little. The following pictures were taken with 1/1000th of a second shutter speed, so that the camera can register even a 1 millisecond delay between the two monitors. So, now lets get to the point where I compare the 120Hz LCD and the CRT display, using the analogue splitter cable. If you try to use an active splitter (with its own electronics and needing external power) you can again get inadequate results as this additional hardware may or may not introduce input lag too… As I already said in the article Samsung 2233RZ and ViewSonic VX2268wm are With the Same Input Lag and based on my previous experiences, testing with two displays connected to the two outputs of a video card and using a clone mode does not give accurate results – they simply vary too much! So in order to compare displays and have an accurate judgment on the presence or lack of input lag you must use a passive video splitter that is capable of splitting a single video signal to two displays. My second video splitter, this time compatible with analogue displays arrived so I took the opportunity to connect the ViewSonic VX2268wm along with the good old Samsung CRT to a single video output of the card in order to test for input lag.
