Samsung 2233RZ and ViewSonic VX2268wm are With the Same Input Lag

October 29th, 2009 · 11 Comments · Other S3D Tech


Today I’ve finally got my Dual-Link DVI splitter cable and was very eager to compare the two 22-inch 120Hz LCD Monitors – Samsung 2233RZ and ViewSonic VX2268wm using the splitter instead of the two VGA outputs in clone mode. I’ve heard that testing with the two outputs and clone mode is not a good idea if you want to achieve relevant data, but instead you should rely on signal splitter cable and a single video output. But until today I was not completely sure if these two methods really give some difference, but after testing with the splitter cable things got more than clear for me. Testing with the two video cards outputs, connecting both displays to them, and setting the display mode to clone is not suitable for input lag testing at all, because it does give results that are way off from the real ones…

This video shows the two 22-inch 120Hz LCD monitors side by side, connected with an Dual-Link DVI splitter cable to a single output of the video card in order to check if there is actually a difference in terms of input lag between the two displays. The video was shot at 240 fps in order to catch even small differences (use the pause button to compare), but the numbers on the timer stay the same on both monitors, meaning that neither one has more or less input lag than the other one. So in the end both LCDs actually perform the same when talking about the presence of input lag, so no advantages for choosing either of them just because of having less input lag than the other. Meaning that when choosing you should consider features and design to get the one you prefer better or suites your design taste more.

When the analog video splitter arrives I’ll also do an updated comparison between these two 120Hz LCD monitors and a good old CRT display to actually measure the input lag of these displays compared to an old CRT….

    i really hope there is few imput lag in comparison with a crt…. i have the viewsonic and i’m very happy

    Do you notice any idea if the ghosting is worse on the 2233RZ compared tot he VX2268WM?

    As concluded in this review comparing the two monitors:

    Before using the DVI splitter with both monitors connected separately I had the subjective impression that the Viewsonic has a bit less ghosting. But after connecting them both and running the same image through the splitter with the displays side by side, I can say that there is very slight difference, but it is not easily noticeable with bare eyes. What created made me think that the ViewSonic is better was probably caused by the different (better) color reproduction it has, which in my opinion makes it better for S3D gaming.

    Try to adjust the viewsonic color to 91 red 87 green and 100 blu. It seem more accurate to me (those are xbit lab stat).

    This differs from one display to another, I’ll measure it with a colorimeter to get the best settings for my screen to see if they are going to be close to these ones.

    what are your setting? (i have no colorimeter :( )

    the samsung is behind slightly when i use the pause, the numbers are the same but the samsung is still fading on some numbers

    I Currently use a 85 hz CRT for competitive Counterstrike: source and i have a massive advantage over lcd’s because of this. My old monitor believe it or not is a 22″ samsung 2 ms 60 hz, what i want to know is do you believe its worth me spending $400-450 australian to get this monitor AND will it be equal or better than my 85 hz crt

    LMS, there are a few places where you can barely see a little difference, but it is so small that I’ll probably be unable to measure it with what I have available. Probably much less than a millisecond which you cannot consider as such a difference between the two ;)

    Fab, it will most likely perform better than what you get on your CRT as CS: Source is able to run with no problems at 120Hz. But please wait a few more days until my other cable splitter arrives so that I can compare the input lag between these two displays and a good CRT.

    Did you ever get to do the Samsung 2233rz vs a good CRT test using a suitable splitter? I mean a chronometer test like the one above.

    What do you mean “clone mode” causes irrelevant results? How do they differ?
