Remember the HDCP fiasco, which came out Feb 2006? What has changed since then? Does every aftermarket video card still not actually support HDCP?
 
The article says the X1900 XT doesn't actually support HDCP, so what makes you pretty sure that the 1950 or 8800 do?
 
I know my EVGA 7950GT supports HDCP as well as my Dell 2007WFP. How this helps me I'm not quite sure yet...
 
yeah hdcp support was one of the major sellign points for the 7950 and 1950 series cards.
 
I think you only need HDCP support if you plan on watching HD content in Windows Vista with a blu-ray or hd-dvd drive.
 
doesnt anydvd have a hd version out now that makes it so your monitor/card doesnt need to be hdcp compliant??

All Blu-Ray and HD-DVD movies don't have the ICT bit enabled, which means that HDCP compliance doesn't matter. But in 2010 or later, they might start enabling it with movies, which would mean the resolution is downscaled by a factor of 4 unless all your involved devices are HDCP compliant.

That's total rubbish. Although it's true that all current movies do not have the ICT enabled (currently planned for 2012) ICT is in no way related to HDCP. HDCP only concerns digital cables (DVI/HDMI) with Blu-Ray and HD-DVD movies, whereas ICT only concerns analogue cables (VGA/Component). ICT if activated halves the vertical resolution of HD content to 540 lines but only happens if you are using analogue cables and thus has nothing to do with HDCP.

HDCP - High-Bandwidth DIGITAL Copy Protection (thus not related to analogue - ICT)

Recent articles on BeHardware stated all kinds of rubbish about HDCP, confusing it with ICT and have thankfully since removed it. I can see this kind of miss-information is still common so please do some research before posting on these forums as people may want to actually listen to it!

You think badly. It has nothing to do with Vista - you need HDCP support, no matter what you use to watch it - if you wan't to do it legally.

Well sorry for misinforming if I got it wrong. I'm still not convinced that I did. Maybe you can help clear this up.

You said ICT only applies when analog is involved. What happens if you have an entirely digital setup, and you use a Blu-Ray player, but one of your devices isn't HDCP compliant? Without that compliance, will you get nothing at all (a blank screen) or will the resolution be downscaled? What will happen?

According to wikipedia, "they" decided not to enable the ICT bit for several years to make things easier on people who purchased HDTV's when they first came out, since those TV's are not HDCP-compliant. That makes logical sense to me, but you're saying that's not the case, since ICT only matters when analog is involved. Then what determines whether the resolution is downgraded in a purely digital setup when HDCP is involved (a Blu-Ray player playing to an original HDTV)?
 
So artmonkey, do you have any sort of response? It still seems to me that the ICT bit applies whenever there's no HDCP compliance, whether it's due to broadcasting out of an analog port or if a digital device in your system isn't HDCP-compliant. I see no reason to believe the ICT is limited to affecting analog.

Excuse my ignorance but just why is HDCP support needed for anything other then High Definition DVD's to satisfy Hollywood's pirating paranoia?

Yes, using anydvd hd will strip it of the protection, but its also illegal. Not to say I'm one to follow the law or anything...;)

Yeah, the laws are kinda fucked when it's illegal to strip copy protection just to be able to view legally purchased content.

Hell, that isnt even a fair use issue.. it's an "I just want to get what I bought to actually work" issue!

But it's probably just a fallacy to hope that a government bought out by the entertainment industry will ever change the laws to reflect and address those issues.
