100 hz and low input lag
These two systems are irreconcilable. 100/200 Hz systems are used to calculate new images based on the ones received. This is impossible to do without introducing input lag. So basically, what you want, is a TV without 100 Hz
For gaming I would suggest you go with a plasma TV. They are faster, have lower input lag and cheaper in the large formats. Try to have a look at the TX-P42G30 or maybe one of Samsung's non 3D-plasmas (since the 3D Samsung plasma TVs still have some problems with retention and you don't want that on a TV mainly used for gaming).
I don't think Philips make very good gaming TVs to be frank - actually they are often the ones with the highest level of input lag.EDIT:
I just noticed that you are not seeking a plasma - sorry about that. Maybe you want to have a look at Samsung's 5 or 6 LED series and then deactive the MotionPlus system. Sharp's LE831S is also fairly good for gaming but it has some overdrive trailing.
