The VX2268wm is a year late, but at least Viewsonic has made the most of the time to work on improving this monitor.  It uses the same panel as the Samsung 2233rz, but makes some general improvements in a lot of areas--especially the accuracy of the colours it displays, which was the latter's main weakness.

Although we don't take it into account in the score for a monitor, it's immediately obvious that the VX2268wm is finished to a much higher standard than Samsung's screen.  There's another factor that becomes immediately obvious, though, and that's the rather weak hardware offering.  With just one VGA input and one DVI input, and a line in connected to 2 x 2 W speakers, it's a rather limited proposition.  It doesn't really stand up to much comparison with the 2233rz, which has a rotating stand (but no speakers or VGA connectivity).

Response Time

When we test monitors, we prefer to count the number of frames of ghosting (phantom images that trail behind moving objects), rather than specifying a number of milliseconds, because response time isn't a reliable measure to compare one panel technology to another.  Worse still, even two screens that claim to use 2 ms TN panels don't produce identical results.  Here's a recap of how how different screens that use different technologies perform:
  • 5 ms TN: 1.1 colour frame, 0.5 transparent frames (for example: Iiyama Prolite E2208HDS)
  • 6 ms e-IPS: 0.4 colour frames, 0.35 transparent frames (for example: Dell 2209WA)
  • Average 2 ms TN: 0.8 colour frames, 0.5 transparent frames (for example: Samsung T220)
  • 8 ms C-PVA 8: 0.95 colour frames, 0.2 transparent frames (for example: Samsung F2380)
  • The best 2 ms TN 2 (not including 120 Hz): 0.35 colour frames, 0.5 transparent frames (the Samsung 2253BW).
The VX268vm does better than all of these monitors, as you can see:

Average ghosting over ten frames

The VX2268vm goes one better than the 2233rz.  It isn't very far ahead, with just half a frame of transparent ghosting less, but it can now claim the crown of the most responsive monitor yet.  It's entirely worth its five stars, especially given that its input lag is less than one frame.  In short, it's perfect for gaming!

If you decide to switch to 3D mode (see inset), you will however have to compromise on this responsiveness, falling back to a traditional 2 ms TN mode--but it's a price worth paying for the 3D experience.  You can read about what we thought about the 3D games we've tried so far in our test of the 2233rz.

When we were testing the Samsung monitor, it was at this point that disappointment began to set in.  ViewSonic hasn't produced a screen that will win any awards for the accuracy of its colours either, but it's still a large improvement.  The deltaE score--the average discrepancy between the colours requested by the graphics card and those displayed on screen--is 3.4 using the default settings, half of what it is on Samsung's monitor.  With those default settings, the VX2268wm suffers from a slightly red tinge, something which is easily correctible using the controls on the OSD.

However, the contrast ratio is far from being stunning.  Falling between 750:1 and 800:1, it's very average.  The 2233rz almost reaches 1000:1.  In our final analysis, though, the more accurate colours are a more important factor than contrast, leaving ViewSonic with three stars in this area, compared to Samsung's two.
5/5 ViewSonic VX2268wm DigitalVersus 2009-10-21 00:00:00

Pros

  • Excellent responsivess: the best we've seen so far
  • New 3D gaming experience with compatible Nvidia hardware
  • Colours more accurate than on the Samsung 2233rz

Cons

  • TN panel, so poor vertical viewing angles
  • Few extra options

Conclusion

The VX2268wm is faster and produces more accurate colours than Samsung's 2233rz, which, for us, makes it the best 3D screen on the market today. Still, ViewSonic will need to think about lowering its prices as the current differences in quality aren't justified by the much higher price.
