In case someone else was wondering about this too. I was recently kind of confused myself.
Starting in August, all current models from the XL and RL series of monitors by BenQ will have new model names. The XL2430T, XL2730Z, XL2720Z, XL2411Z, RL2455HM and RL2755HM models by BenQ will be re-released as the BenQ ZOWIE XL2430, XL2730, XL2720, XL2411, RL2455 and RL2755 respectively.
More details in the article. I downloaded the user manual for the XL2430 and it does indeed have motion blur, even though that's not even mentioned in the specs: http://zowie.benq.com/en/product/monitor/xl/xl2430.html
