A REPORT said an implementation of a system wide content protection scheme in Microsoft Vista will mean many screens will display a "monitor revoked" message.
According to an article in PC World, the scheme called PVP-OPM is intended to stop pirated disks from displaying their content.
But a side effect means that the same scheme will lock out displays which don't support PVP-OPM.
The same report, here, claims that there are very few wide screen desktop monitors which will support the scheme. So even if you're law abiding you're going to be in trouble.
And Blu-ray and Toshiba HD DVDs need Windows Vista, while Windows XP won't support HDCP, Intel's "high bandwidth digital content protection". So there's no point sticking with your old OS.
Oh yes, the OS times they are a changing. And the hardware manufacturers are no doubt rubbing their hands with glee at the prospect.
