You should ask Greyex. He returned the Phillips and bought the Samsung. Also, will you be happy with this on your screen? https://www.youtube.com/watch?v=zmmhsORVv5c.
No I would not be happy. But is that a common problem with the philips in general or was that simply a bad unit?
Also, if the philips is really that much better in constrast and input lag, it may be worth the trade off since the problem only shows in a specific scenario.
