While these pixel response tests show the U2713H to have pretty fast transitions and low levels of motion blur, there is something else going on as well here which can't be picked out by the camera. All of these other TN Film models are running at 120Hz refresh rates, which allows for improved 120fps frame rates and the support of 3D stereoscopic content as well. This can really help improve smoothness and the overall gaming experience so these screens still have the edge when it comes to fast gaming. From a pixel response point of view the U2413 performed well, although the overshoot in certain transitions was severe. There are some other areas you still need to think about when it comes to high end gaming. It couldn't keep up with the very fast TN Film models with 120Hz support.
The responsiveness of the U2713H was pretty good overall. We had measured a pretty low average G2G response time of 7.2ms which was good, although we'd seen some high overshoot in certain transitions, especially when changing from dark to very bright / white shades. In practice it didn't feel quite as fast overall as the U2713HM model or some of the other popular PLS-based models we've tested. Keep in mind though that this is aimed at higher end uses and the semi-professional market and so the performance for gaming is obviously not a number 1 priority for Dell. It should still be perfectly adequate for most gaming, but those wanting to play fast FPS or competitive games may want to consider some of the more mainstream (and more suitable) models available, or better still, some of the 120Hz compatible displays out there.
