if you have the dough, buy this monitor. By the time you even have to worry about HDCP (even assuming that this monitor doesnt support it) you will upgrade your monitor again. SED is coming out in 2007 starting with large HD screens, and in early 2008 we should start to see large computer screens (20 and up). just imagine 100.000:1 contrast, and below 1ms response times. who wants LCD anymore? And I guarantee, you will not be watching HD movies on your computer for a while. At least not until they crack ACSS... (give it 6 months and some jew from sweden will find the keys again).
if HD and Blue ray comes out in late 2006, and so does vista, i predict both vista and HD media, will become common and affordable about half a year later. so think more mid 2007. wait another half year, and get SED. then your really set!
