would a 6600GT be able to perform well at 1920x1200 resolution...?
(thinking about the dell2405FPW 24" LCD). mainly i'm concerned about
openGL performance in Maya, and DVD playback, i would want no jerkiness
for either application. gaming performance would be cool but not essential.

i know that SLI has problems with widescreen and DVI, so not much point
in considering it yet anyway.

No. The sweet spot for this chipset is 1280x1024 according to some
recent tests in a UK PC mag.

This is a mid-range chip, you'll need to go for top-of-the-range for
3D use.

In my limited experience, the 6800GT is too slow for smooth 1600x1200 video,
as it appears to rely on software scaling. So I would say no, the 6600GT
would probably not be the best choice for 1920x1200 video...

DVD is fine, apps like Maya and such should run fine, too. Games might
require to use a lower resolution, though. I have a PNY 6600GT and a Dell
2005FPW, HL2 runs fine with everything max but without AA/AF on 1680x1050...

IMHO it's not worth considering price-wice anyways. A single GF6800GT or
Ultra is cheaper and faster than a SLI 6600GT setup...

I was reading an SLI test on Beyond3D yesterday in which the 6600GT SLI
setup repeatedly outperformed the generic 6800 SLI setup for some reason.

thanks to all who replied. i will wait for a few months until i've built
up a new system (with new Tyan K8WE SLI mobo & dual 6800GT, providing
nVidia fix the widescreen problem with SLI).

getting a bit OT does anybody know whether the new Tyan dual opteron
boards purchased now will support the dual-core chips being released
early next year...?

that's over half a million pixels less than the 2405... a huge
difference in stress levels on the graphics card...

I said that games certainly won't be playable in full resolution. But
nevertheless DVD and professional apps llike Maya should be fine (they are
fine at 1920x1200 on slower cards)...

Sure, since a single 6600GT outperforms a 6800 (non-GT/non-Ultra) in almost
all situations already...

in this thread i've heard 2 people say completely opposite things about
DVD performance with a 6600GT at 1920, and watching full-screen movies
on the LCD would be the 2nd most important task.... so not sure what to
believe on that yet...

Strange, as both people (I assume You are talking about Arthurs and Dr Teeth
postings) are talking about the 6800 and not the 6600GT. The funny thing is
that the 6600GT has much better video acceleration hardware which also
supports HDTV, and the 6600GT doesn't...

Besides that, it depends on what exactly You want to do. DVD watching is
different from i.e. watching DivX movies or WMV movies (especially WMV-HD),
and it also depends on the DVD player software You use...

Besides that, it's IMHO totally stupid to rely on watching DVDs at
1920x1200, simply because DVD Video has a max resolution of only 720 x 576
pixels. So even if You set Your gfx card to 1920x1200 the DVD Video has to
be interpolated, and the resulting picture isn't better than with Your gfx
cards at i.e. 1440x1152 and having the display interpolating the image...

If I were You I'd concentrate on things that are much more essential than
DVD playback which hardly is a problem for any somewhat modern gfx card...

Replace this "6600GT" with "6800". Sorry.

it has to be 1920 for several reasons, no-one can really be bothered
changing the res of a monitor just to watch a movie, and interpolated
DVDs i've seen still look great. it has to be no less than 1920 because
as i understand it changing the native res of an LCD would look bad,
worse than interpolating the DVD movie itself.

No matter what You do, DVD will always be interpolated. If the gfx card does
the interpolation or the display does makes no difference. Using a high
resultion brings You nothing. That's btw one of the reasons why most LCD TVs
use XGA or SXGA displays. Higher resolutions simply don't offer a better
picture.

Besides that, having the display interpolationg lower resolutions isn't
always as bad as it sounds. Of course it usually looks really bad if You use
1024x768 on a 1280x1024 (SXGA) display or if You go down to 800x600 on a
1024x768 (XGA) TFT. But the image quality on i.e. a HP L2335 23"-Display
(native 1920x1200; we have dozens of them at work) on lower resolutions like
1600x1024 or even down to 1024x768 is very good and sharp. That's because
such high-res monitors have lots of pixels on which even lower resolutions
look good, while usual 15" XGA and 17" SXGA TFTs have a much smaller number
of pixels which results in a unsharp image on non-native resolutions.

But of course if You insist You can watch DVD in 1920x1200 with a 6600GT
without problems...

Actually there has been a lot of success in upscaling DVDs to HD
resolutions. There was an article a year or so ago about it on one of the
hardware sites that showed screenshots of Star Wars Episode 2 from standard
DVD video and the upscaled version and there was quite an improvement.

I know, but there are quite contrary opinions around about upscaling. I've
seen it myself several times, but I don't think it's really that good. Most
people simply forget that the visual information (detail resolution) in
720x576 isn't sufficient for higher resolutions. There are some tricks to
make some(!) (not all) scenes look better, but that's it. It's not even
close the quality of a high resolution video stream, and in most scenes that
aren't taking place in the dark the picture also can get worse...

Of course HDTV video (like wmv-hd) is a different story, but for that the
6600GT also is one of the best cards available...

I beg to differ. My 6800GT card displays video in 640x480 overlay, and it
looks absolutely horrible compared to when I use my Parhelia, which scales
the overlay to the chosen destination resolution, using 10 bits per colour
while interpolating. Gone are the horisontal stripes that you easily see in
640x480, and aliasing effects are severely reduced.

The video quality of the 6800GT is so bad that I'm about to yank it out and
put the Parhelia back in, despite not being able to play $300 worth of games
plus having spent $400 on a card I won't use.

Provided you use Windows XP. If you use Windows 2000 (which has some
advantages over XP, where XP has been crippled), all the extra video
features are disabled. This is not an OS problem, as other video card
producers have no problems doing HW accelleration in W2k, but likely a
conscious decision from nVidia not to support W2k more than they have to,
due to the smaller user base.

What software are You using? I have no problem watching DVDs at 1680x1050
with my PNY Verto GF6600GT PCIe...

Maybe You should just choose a different card, or check Your
setup/configuration...

That's BS. The GF6600GT works as well with video in W2k as it does in
WinXP...

I really suggest You check Your setup...

Video overlays should be independent of the software used.
If the software does it for you, bypassing the drivers, that's cheating.
:)
So the answer is really "any program without special nVidia support".
This includes Pinnacle Studio 8 and PCTV Vision, BeyondTV 3, Intervideo
WinDVD Recorder, Bink/Smacker player, and a bunch of games (where
cut-screens don't appear on the second monitor at all, even when an overlay
is used).

I tried an ATI X800 pro first. That was much worse -- it can't do overlays
to a second monitor at all unless you use clone mode.

As for configuration, I'm uncertain what to check for. It's not like
there's a lot of options in the nVidia drivers for overlays when running
W2k. There are some things I am sure are just plain wrong with the driver
setup, though, like:

- Having no less than *eight* monitors show up in the device manager when I
really have two. If I remove any of them, they reappear if doing a hardware
scan. I have four "Default Monitor (winseset)", two Envision monitors and
two Mitsubishi Diamond Pro monitors listed, when in reality I have one
Envision and one Diamond Pro. No matter what I try, the extra non-existing
monitors reappear in the device manager as long as the GT6800 card is
installed.
- Whenever I select the "GeForce 6800 GT" tab in the display properties
advanced settings, the primary monitor degausses and goes black, and I have
to turn the monitor off and on again to get the display back. Same when I
OK out of the display properties.
- DDC/CI doesn't work. I refuse to believe that a $400 card doesn't
support this, and think it might be related to the above mentioned confusion
with number of monitors.

There's at least a few places where XP has been deliberately crippled:

- Multiple colour profiles per monitor.
- For networking, having more than 10 half-open connections (which has been
crippled even for XP Pro with SP2).
- Being able to "Remove Hardware", so you can revert to a previous version
of a driver if the latest one gives you problems, even when there's no
specific uninstaller.

Nope. Look at nVidia's site:
http://www.nvidia.co.uk/object/dvd_decoder_sysreqs.html
Or this review from Anand:
http://www.anandtech.com/video/showdoc.aspx?i=2305

In short, thne nVidia hardware decoder isn't available for W2k (and neither
is WMP 10 which you need to take full advantage of all the options).

> I really suggest You check Your setup...

I'd love to, but I don't know what to check or how to fix what's wrong,
beyond what I've already tried. Do you have any specific suggestions?

Yes, _should_. However, reality is different. I for example have no problems
with PowerDVD while WinDVD sometimes gives me artifacts...

Fine. But if You re-read my postings You might notice that I was talking
about DVD playback as was the OP. Not about watching TV or any video
players...

Can't confirm that. One of my friend is running W2k because of paranoia on
his P4 with 6600GT PCIe (with one 19" TFT and an Liyama 17" crt), and he
doesn't have this problem...

Also this doesn't happen here...

Again, no problems here...

This definitely isn't a problem of the Nvidia W2k driver (which btw. is the
same like the XP driver). Your system really screams for help. I don't know
what hardware You have, and remote diags often are difficult, but all I can
say is that the Nvidia drivers work flawlessly under W2k as they do under
XP...

You said You had an X800 first. It's possible that there are remainings of
the ATI Catalyst driver that hasn't been uninstalled properly...

I can add as many colour profiles to my monitors as I want on my XP Pro
machine...

With SP2 MS lowered the TcpNumConnections value to prevent DDoS and flooding
attacks. The options were already there in WinXP Pre-SP2 and even W2k, but
not activated. If You use XP SP2 You can raise the number of connections by
hand. XP before SP2 behaves exactly the same like W2k.

That works exactly the same in XP than in W2k...

These are the requirements for Nvidias DVD Player software(!). This has
nothing to do with the video capabilities of the GF6600 gfx cards which _do_
work fine under W2k...

> Or this review from Anand:

Anandtech is unreachable atm. Don't know why...

No. You need WMP10 for WMV-HD and for using the Nvidia DVD Decoder. You
don't need it if You want to use the DVD decoding features of the Geforce.
And that's all the OP wants...

I'd check if there are any remainings of the ATI drivers on Your computer
which should be removed. If You use a board with non-intel chipset get the
latest mainboard drivers from the chipset manufacturer website. Always use
the drivers from the chipset manufacturer and not from the mobo/gfx card
manufacturer site as the latter often are old.

That would happen in XP, too. I think it has to do with how NVidia has
implemented nView.

This occurs when your monitor isn't sending EDID data via DDC.

The card absolutely does support DDC (and as seen by the problem mentioned
above, relies a bit too much on it). Either your monitor does not support
DDC or there is some type of compatibility issue.

Mitsubishi DiamondPro 930SB, which is probably the best aperture grille 19"
you can get these days, after Sony stopped their CRT line.
DDC/CI works fine when using a Matrox Parhelia card, but not when using the
6800GT.
I'm using the monitor through a DVI->VGA adaptor plug, but I did that with
the Parhelia too, so that shouldn't matter. The only thing I can think of
is that the 6800GT can't handle a situation with the monitor on the DVI port
supporting DDC and the one on the VGA port doesn't.

Reality is different for nVidia then -- with Matrox cards, overlays work the
same independent of the program you use.

All scrubbed, including a manual registry and inf scrub after using ATI's
removal utility.

The thing is that hardware accelleration is only available through the
driver extension that comes as part of the dvd decoder. (You don't have to
use the nVidia player, but it comes with the decoder.) If watching DVD
without the nVidia decoder, you are basically doing it all in software, even
though the card itself is capable of basic video HW accelleration.
Check the CPU use if you don't believe me.

The DVD decoding parts are not available unless you buy the DVD decoder.
You can still watch DVD, of course, but without hardware assist.

All that checks out.
All previous drivers scrubbed.
P4T533, latest BIOS, latest Intel 850E chipset drivers.
P4 3.06HT, 512MB PC4200 32-bit RDRAM
W2k SP4 + all recommended patches
All other drivers latest stable or latest WHQL version.
BFG 6800GT OC
nVidia 71.84 drivers
(I never installed the drivers from the CD that came with the card -- the
setup program on the CD fails unless you already have video drivers
installed as it needs to play a video first, so I figured that whoever
assembled the CD wasn't too smart.)

When installing the drivers under W2k, no less than *six* reboots are
required before everything is up and running with dual monitors in
independent mode. Probably less under XP, but still...

Playing a DVD in PowerDVD or WinDVD and checking the status window will
clearly show you that iDCT and/or motion compensation acceleration is
being used. The NVIDIA DVD decoder software is not needed for this..

You're wrong. You don't need the Nvidia software to be able to use the
6600's hardware acceleration. You need the software to use the other
functions, but not DVD playback.

I don't have the Nvidia Decoder software, and playing back a DVD at
1680x1050 only raises CPU utilisation by 2-3%. And PowerDVD clearly says
it's using hardware acceleration...
