The HD151X  supports Optoma’s wireless projection technology, so you can move your projector around the room without having it tied to your AV cabinet.  In the same room, we were able to place the HD151X and our PS3 about 35ft apart with several boxes and obstacles in the way before the signal started cutting out.

Whereas BenQ’s system only managed about 12-15ft when we placed our PS3 in the next room, the WDH200 achieved more than double this distance with the same number of obstacles in the way, as we got to the other end of our testing room roughly 30ft away and still had a clear picture. This makes Optoma’s WDH200 the superior wireless projection kit.
