With its excellent contrast and relatively well-calibrated brightness, the 930BF is a good monitor for office applications.

Video games are another area where it excels. Provided, obviously, that players aren't too demanding about color rendering in their games, because transitions generate chromatic aberrations on the contours of moving objects. So is that really so bad, you're asking? Yes and no. It's a little like the three fine lines that hold the matrices of Trinitron CRT monitors in place. You don't notice them until somebody points them out to you, but once they do it's all you see. One way to attenuate the phenomenon is to set the vertical refresh rate to 75 Hz. That may seem odd, but it works relatively well on monitors where the electronics specify Overdrive as a percentage of the scan time and not as a set duration.

Video was the big disappointment with the 930BF. The viewing angles are fairly wide, but the video noise was unacceptable. So forget about video.

Conclusion

If you're a gamer, the 930BF might attract you, but I find that the gain in responsiveness isn't worth the loss in flexibility of use. The VP191b is suitable for other uses and much more ergonomic for a price that's barely higher. 4 ms as offered by Samsung was a nice try, but I'm not buying it.
