Conclusion

The deep blacks, accurate colours and low input lag on Sony’s latest high-end (W series and above) LCD HDTVs need no further praise, so we’re left to comment on the Sony KDL40Z4500’s 200Hz Motionflow implementation.

The good news? There are surprisingly few kinks for what effectively is the first incarnation of 200Hz MCFI technology. Now the not-so-good news: any resultant improvement in motion clarity isn’t really leaps and bounds ahead of what 100Hz LCD televisions currently offer when it comes to real-life viewing.

So while the Sony KDL40Z4500 holds the current record for the highest motion resolution we have measured on an LCD TV so far, pound-for-pound we think that the Sony KDL40W4500 (equipped with 100Hz Motionflow) represents better value-for-money.
