In which case integrated HD2000 or HD3000 via HDMI on mobo and Sandy bridge is just fine without need for any card at all.

Also the IDT ViewXpand VMM1400 chipset isn't a feature set of the nVidia GPU. It's an addon solution requiring it's own drivers and software and it doesn't create discrete displays beyond what the nVidia two clock generators do. It simply creates a clone of one of two discrete displays and that chipset adds the ability to flip them around or it can "span" multi monitors in a way they appear as ONE MONITOR. It's for a wall of screens in a department store. duh

It actually treats it as one big display exactly the way AMD Eyefinity Technology does. Basically it's a chip to give nVidia the features Eyefinity ALL READY PROVIDES ROTFL

Here is info from IDT on that chipset.



And from a reviewer at Newegg



Now say thanks Assassin as you prob would have bought that card thinking it would work for your customer as independent displays. It will give you two discrete displays you can clone and again as I've been trying to pound into ppls heads it has only TWO clock generators!

This just says to me you can get more than two independent displays. It's in their literature. Another reviewer at Newegg states that and the person you had on hold replies at Newegg that he does. I'm sure Assassin would do more research than looking at one link to spend close to $300. Anyway sorry Assassin for the off topic, as OP you were looking for a dual hdmi out solution and you found a few options as offered by the manufacturers.

Again these comments are from a conversation I had with Renethx who has done more testing than many of us combined:

Quote:


Every latest GeForce card supports two-independent video/audio streams over HDMI and DVI (extended desktop mode; use a generic DVI-HDMI adapter to connect the DVI port to HDMI IN of one of the displays). It also supports clone mode if the two displays have identical resolutions/refresh rate (audio is different: two audio streams are still supported).

It is a great looking case, but I must be missing something. I don't understand the need for a touch screen at the htpc. IMHO I would like a touch screen remote; maybe a tablet pc. But I can't Imagine wanting to use a touch screen at the pc. at least not on any regular basis. what am I missing?

Still building. Have to get a slightly different CPU cooler.

Also were able to secure a few 4TB hard drives.

Just found this thread, and hopefully someone can point me in the right direction.

I have a Sapphire 5670 and I am using both the HDMI and the displayport connections in the following way:

HDMI -> Onkyo 606 -> Epson projector (1080p, 60hz)
Displayport -> 1080p TV (via Displayport - HDMI connector)
Clone mode

Issue:

I can only get the sound coming out of one of the two devices - whatever was activated first. So, if I start with the TV, I can't get any sound coming out of the Onkyo. If I start with the Onkyo, I can't get any sound from the TV.

Video is OK - both devices can always display 1080p video.

Important: I don't need them to display video or sound at the same time. But as of today I need to reboot Windows everytime I want to switch from the TV to the projector. Ideally, I just want to turn one off, turn the other one on and get it working.

Is there any way to make it work? Do I need a different card?

I also tried the HDMI Splitter option, but then I got into a different issue: If the TV is the first one recognized by the splitter (hdcp compatible), only stereo sound comes out of Windows media center. If the Onkyo is the first one identified, it will bitstream TrueHD/DTS-HD to the tv, which doesn't work either.

So the solution would require Windows to recognize what device is "on" at the time and send the appropriate sound.

Probably dual cards.

Or,

You can always change the audio device by right clicking the speaker icon on the bottom right of your screen to go into the "playback devices"

Here you should select the one you want to send sound to.

You should not require a restart to do this.

But you will only be able to send sound to one at a time.

Dual sound- will require dual HDMI processors- not just a video card that does dual video. That is different.

Thanks Mfusick

I tried the playback devices option, but I only have1 device there - the HDMI one - even when only the Displayport is the one being used.

With adapter, the dp will show up as hdmi. Try extend mode even though it's more labor extensive. That's how I have it set up with 605.

Just tried using the extended desktop mode but got the same results. The sound will only come from either the HDMI or the Displayport - whatever was active first. And as soon as I turn off the device that is using the sound, the HDMI Playback device will show up as Disconnected.

I tried to disable/enable it, no luck.

Would a NVidia card help? Earlier in this thread someone said that NVidia cards are capable of dual audio coming from 2 digital outputs.

Never got simultaneous output nor stated I did. Just that you can switch from one to the other.

Still coming.

If anyone ever uses this case know that you need SATA cables with "L" connectors on each end for all connections.

Had to order some.

I started using these more. I find they work better in many applications.

I use them on my RAID PCI card. The angle helps make it neat and secure.

Thanks for your help anyway. I ended up buying a Nvidia 430 card and now I can achieve my goal. The NVidia card reports 2 audio devices and I can either listen to them at the same time (same audio) or turn off the TV/turn on the Receiver with no need for reboot.

Since they are coming from different audio outputs, I can have the TV set as stereo and the Receiver as 7.1, TrueHD/DTS-MA.

Now I need to find what are the best settings for the Nvidia control panel.

Well with this report I stand corrected about the audio device count on the nVidia cards... UNLESS it's just a routing/cloning option....

hey danbez can you send different audio to each output separately? In other words does each playback device appear as a different discrete audio device?

I find this amazing if it's the case. Also people should be aware of this and nVidia should add the feature to their marketing material!

BTW how do you use them at the same time? I'm not aware of windows audio API being able to do that. I currently have three sound devices in my machine. ATI 5000 series, onboard ALC889 and Asus Essence ST. I can set one to be the default for windows. I can also select a separate audio device from the windows default if the application supports this like foobar and XMplay. I don't see how one could mute each discretely...

Just wanted to point this out and say thank you for taking the time to post it.

I am wrong often and actually like it when I am wrong as it gives me a chance to learn something.

The older I get the more likely I am to admit when I am incorrect.

Many of us on AVS know this about NVidia. I am not sure why they don't market it better as you say.

LOL

I'm very similar and also love to lose a heated debate as I end up learning as well.

I have a funny feeling yourself, Shark007 and me are very similar characters!

Again I tip my hat to you two as I really don't think there are any others in the community that has contributed more to HTPCs.

Is Nvidia only capable of this?

Does this not work for ATI or AMD?

THe" reports two devices" and "or turn off/on tv/receiver" I've done with AMD and Nvidia. Would like a little more specifics on "listen to them at the same time" Thanks, cause I have a 430 too. Are you using clone?

That's the way I've gone, an I3 with an HD3000 and a fanLESS (i.e., NO FAN) case. I built a completely silent HT computer, but WMC balks at recording HD files when all you have is 60GB (of 120GB) free. So, I use an external 3TB hard drive for that. (Even though I use MCE file mover to copy the HD files to an unraid server.)

To be honest I'm still cynical about it... LOL

I know for a FACT this can't be done with just one video card with AMD. The DVI ports simply don't have audio. Where you using a DP to HDMI adapter or something to that affect? I'm not even sure if the DP ports provide audio with AMD as I've never used them. It's apart of the DP spec to have audio though so perhaps that's it ehh... I'm still shocked the audio streams to each port can be addressed/set discretely. Windows audio API doesn't even have a feature set to route like that between audio devices.

DVI can indeed carry audio.

Its been discussed a ton on here and many doubters have lost that bet.

Still building.

These things take time. Custom HTPCs like this aren't quick and take patience and often we have to order parts 2 or 3 times to get everything the way I like it. Sometimes if I don't like something I will send it back and order something else.

The guy purchasing it has been awesome to work with which makes it even better for everyone involved.
