Are we talking about component output for the TV? Does ATI do this entirely via the Rage Theater chip or is there something internal to R300 that gives this capability? I remember Anandtech saying the HD output signals really give a much cleaner TV output quality.
It's a bit disappointing, but my favourite TV for the last year has been the Samsung DLP series, and it has a DVI input AFAIK. I think the Grand Wegas have it too. I don't expect TV manufacturers to do this for the lower end HDTV's, though.
On the other hand, I'm also running a cable from my AIW to my TV across rooms, and I'm pretty sure a long DVI cable would not only need big ugly holes to get the plugs though the wall/ground, but would also be expensive
This would be a shame, I agree. I'm not planning to buy a VC soon, though. Just blabbering on about some issues other people may also have.

I'm not so sure about the validity of these claims of no HDTV support, because the tech specs on the 6800 say:
Would be nice to hear more about this though.

Generally when someone says "HDTV ready", that implies that a signal can be received. The wording above is a bit deceptive, and I can see that now.

By the way, this is what someone at NVN said about HDTV support:

Someone just posted this at NVN about using DVI out on their HDTV with a 5900U:

Someone else at NVN just looked at the leaked Forceware v61.21 driver, and said that this driver includes custom resolution settings and HDTV support

Um....and just what does that link have to do with the 6800's?

Everyone needs to give this whole thread a read....JJ123, none of this refutes the story....... except the hearsay evidence of a notorious nVidiot. Everything else in the thread points to the fact that nVidia seems to be telling the same half truths (or no truths!
) as usual........^did you even read the thread? instead of resulting to call somebody a " notorious nVidiot" theres a little bit more info than you claim to notice...

Yes I've read it, and I've been at that site for years...... the person in question has been a source of bad info for years..... And the point of the original Bit-Tech post was that nVidia has lied about the abilities of the NV40 for HDTV... Not that it couldn't do any HDTV. The points that are now coming out is the the NV40's hardware is no different than "any" card from the previous generation.... the info nVidia gave at the introduction of the NV40 was that it would have SOOOOOO.... much more capabilities on HDTV......
There are many that are interested in a card primarily for it's HDTV abilities. Believe me, at the moment, they all fall far short of what most of us want FOR HDTV. If the NV40 is no more capable that a NV3x, a R3xx or RV3xx, then it's not the card that was being pushed at it's intro........

What the hell is the real story here??? I just got a 6800U and was expecting HDTV support :?
Statements to the effect that the 6800U supported HDTV were all over the place prior to this info?
If this is the case then this card is going back!....how can Nvidia possibly claim one thing then deny it at the last moment.......if this turns out to be true then this is REAL BAD.

It's nice to see that he's gotten it to work with a FX5900. Only problem wrt to this thread is that we're talking about the NV40, which would be the 6x00(Ultra/GT/XT) cards..
Oh, and as for the "HDTV-ready", there are several ways in which to interpret that sentence (just quoting those two words is a bit out of context), and even if it turns out to be "HDTV-ready" it might not necessarily mean that it support HDTV without any extras.
(Quite a lot computers have been sold as internet/broadband ready, just add the modem, the software, the account with the ISP etc, and you can use it)
What is the purported issue, exactly? That NV40 can't accept an HDTV input (which is what I interpret "HDTV-Ready" to mean on a video card) and then encode it using its onboard MPEG2 encoder? Or that the NV40 can't encode an HDTV signal for output to an HDTV monitor?
Here're two blurbs from the 6800's product sheet. Which parts are BitTech disputing?

Note the difference between the product description:
"HDTV-ready MPEG-2 decoding"
... and what the article stated:
"both the core and the existing reference board have no capacity to support an HDTV signal"
So the card is capable of decoding MPEG-2 to an HDTV-Ready signal, but not an HDTV signal. I would take this to mean that the signal it sends does not need to go through an HDTV receiver. Instead, it can pump directly to an HD-Ready TV (or HDTV Monitor) and be displayed at full 1920x1080i on the screen. If it were sending an HDTV signal (the kind it doesn't support), it *would* need to pass through a receiver/decoder before going to the TV.

Just from reading:
-it won't 'tune' ATSC or QAM (methods of broadcasting an HDTV/mpeg2 stream over cable or over the air)
-it will accellerate mpeg2 decoding, assuming you have a card that can get the mpeg2 stream 'off the air' and feed it to the driver
-it won't output component output (a means of connecting to most HDTV sets, in addition to DVI and VGA)
-it won't support HDCP (copy protected DVI)
The ATI card is the same, except it outputs component video.
And yes, this website is making a mountain out of a molehill.
There's a lot of terms being bandied about (in this thread too) that show a fundamental lack of terminology and what HDTV actually is.

matrox, there are many steps to supporting HDTV. To claim that that "lied" by asserting the NV40 does more than other NV cards to support HDTV is a crock. Being able to encode and decode 720p and 1080i streams in real time is one of the cornerstones and that has been upgraded in the nV40. NVidia specifically added acceleration for the most important part of dealing with ATSC broadcasts: decoding and encoding them.
The fact that it doesn't have 100% of the HDTV pipeline in the core (component video, HDMI/HDCP) is irrelevent. These have been historically handled by external chips, because there are too many standards to support and it is best to treat the framebuffer as the final stop, and let external chips do the conversion for NTSC/Component/DVI/HDMI/ATSC/1394/etc Almost every piece of HD equipment I have takes component, DVI, and DTCP Firewire inputs, so it would be quite ludicrous to try and shoe-horn all of these into the core.
BTW, where's your indignation of ATI's Hyper-this and Smooth-that HD buzzwords. They seem to add HD onto every marketing buzzword.
