Two HDMI Outputs with Different Resolution from one HTPC?

post #1 of 20
Thread Starter 
My HTPC will be used to play back DVDs and Blu-Ray's ripped to an NAS, and that's about it. To make a long story short, I'd rather let my receiver (which cost more than my entire HTPC will) upconvert a 480P DVD signal to send to my TV than have the PC do it, and would rather not have to switch resolution when I then want to play a Blu-Ray at 1080P. Can I use one of the motherboards from the "How To" thread, with on-board HDMI, to send a 480P signal, and then add a Xonar to send a 1080P signal, without changing any settings in the HTPC on the fly? I know I'll be wasting an HDMI input on my receiver, but I have an extra. I guess I'd also have to use two different media players, but is this possible? Thanks.

You would have to configure the two HDMI ports in extended desktop mode and not in clone mode in order to have different resolutions. Then also have an ICON on the extended desktop for run any application such as your BR player app on the extrended desktop so you can start it on from either port.

I'm reading that you may need to use the same driver for both monitors, so does that mean that I can't use the on-board HDMI and then add a second through a PCI card? Do I need to use two PCI cards? Thanks.

Nvidia has one driver
ATI has one driver

so if you have an 8200 you could use any other nvidia card.

Please excuse my ignorance for a second, but is the Xonar HDAV based on an Nvidia chipset? Thanks.

Do not get a card with onboard video.
Get a graphics card with two HDMI outputs if you can. you may only be able to find one with one DVI and one HDMI output but at least you will have the one driver problem resolved.

actually what he said.

DVI is 100% compatible with HDMI.

Just get any old card with Dual Digital outs, run one to your xonar and the other to your TV.

Right on!

And have three displays. Works great with the Xonar.

Just for posterity: any video card made in the last few years, absolute minimum, will do a far better job at scaling content than your receiver will ever hope to do. The very best up-scaling chips on the market don't have a hope of competing with the amount of raw power that a mid-end video card has.

Basically, your video card has a hell of a lot more resources available than your receiver does, and additionally has the help of the software you're playing the video back in as well.

Outside of broadcast grade video solutions, I don't think you'll do any better than a recent Nvidia or ATI card combined with a decent media player with good scaling implementation (ie not something sloppy like nearest neighbour).

I'm in a similar situation--my scaler is a Lumagen VisionHDP (much better than graphics card scaling). I haven't been able to find a good solution so far. I thought about programming a key on my Harmony remote to switch resolutions when I want to watch SD material. I guess I would need another key to switch back to HD resolution. Anyone know if this would work and/or how to do this? I'm using Media Browser in VMC.

The proper solution for those wanting to use an external scaler/processor, as far as I can see, is to just drop $150 (or whatever they cost) on an Oppo DVD player that will preserve the original, unmoleseted 480i signal over HDMI.

You'll never get a HTPC to work with multiple resolutions in anything close to a user-friendly manner, if it's even possible to begin with.

This motherboard and one of the supported Nvidia Hybrid SLI video cards will give you the capability to run Multi Adapters.

That won't work for DVDs backed up to hard drive, an NAS actually, though.

And I can set different resolutions? Any recommendations on a compatible card?

Go to Nvidia's site then Technologies/Hybrid SLI, having problems with the link. It sounds like you can run independant resolutions.

I just read that and found it funny that Microsoft used the words "upgrade" and "new restriction" in the same paragraph. It looks like Windows XP is more friendly to having drivers from different vendors, whereas Vista requires that the driver be the same. I have an unregistered copy of XP that I was going to give this a go with anyway, so that just pushed me a little further away from buying Vista up-front. Thanks, guys.

Yeah, I too was surprised by XP being able to handle different ATI/NVIDIA, but that's a plus to keep in mind. Now, how does W7 handle this?

I have to agree with the comments relating to upscaling on the PC. Between the far simpler implementation of a single output and the higher quality of the scaling you really do not need to go the complex route you originally mentioned. Far better to get a good Nvidia or ATI card and let it do the scaling. ATI cards do have the additional benefit of 8-channel LPCM output.

I have an Integra DTC-9.8 which has a very good scaler and I actually do not use it. I let the HTPC scale DVDs and frankly have a hard time seeing the difference between them and Blu-Ray on the same system. Admittedly some of this is due to my projector being only 720p but the point is that it works very well these days.
