I am also looking at the Philip's LCD's. The model you have shown has the perfect pixel HD engine, and all of these in Europe support 100Hz and 24fps as far as
I know. The current models also have a 3ms reaction time and the new models due out in April will have a 2ms.
Please see my tread:-

I'm not sure why the US model dose not support this, and I can't see the Philip's model number on the costco page.
Have you looked at the US Philip's web site to confirm? It might be worth checking out.
