I need to find an HD capture card (720p) which will allow me to pass the 360, PS3 or whatever video signal to my PC without any input lag. Anyone know if such a thing exists? I have and HDMI one already from Avermedia and it lags by about 1/3 of a second.

Reason I need this is not to capture video, but so I can scale the 360 video signal and pass it on to 3 monitors set up in portrait mode. Below is image of what I am trying to do. Need it to be input lag free...

It's physically impossible. There will ALWAYS be lag, period.

Now, if you're looking for sufficiently insignificant lag, that's a different story altogether.  I'm not certain about the cards, but part of the solution involves having a sufficiently powerful system to work with the card, and having a card that has good software/drivers. It's not just the card hardware itself that matters here.

I see, thanks for reply.

Yeah with an overclocked i7 and top notch hardware I am getting lag so I don't think PC hardare is the bottleneck.

That really sucks as I was hoping to somehow get consoles working on a 3 projector setup I will be setting up shortly. PCs have no ptoblems scaling to whatever resolution you throw at them using eyefinity or nvidia surround but consoles can't do that without capture cards.

Just a question, why would you want to play a console?

Consoles still have some games PCs don't get which I'd like to play.  Obviously it wouldn't be a screen setup designed for consoles as they would still be running in dinky 720p, while PC games would have no problems scaling to 3240x1920. But I'd still love to play the Halos, Bayonettas, XBL/PSN stuff and a slew of other games that don't make it to PC...without having to buy a 4th projector to play them on. :)

Oh I just have that TV thing over there...

OK your setup consists of 3 vertical monitors and judging from your photo the 3 monitors give you a 16:9 aspect ratio with a screen size of about 32 inches.

Solution: buy your self a dedicated 32 inch TV or Monitor and you won't have to worry about input lag, nor the convoluted setup you want.

you probably already thought of this but disregarded it, but sometime the best solutions are the most simple ones.

lol, while I appreciate the reply, it just isn't what I am looking for. This was just a test setup to see how it works with PC games. It works great...

Now I am looking to  do this with 3 1080p projectors in portrait mode on a 100+ inch screen(16:9 ratio). I want the 4K resolution for PC, but would love to be able to play console games in their 720p awesomeness on the giant screen.

I use Blackmagic Intensity Pro for my PS3 and Wii Captures. For the PS3, I have a HDMI splitter with one cable going to my TV and one going into a HDFury 2 to a component splitter box to the capture card for 720p capture(HDCP is fucking gay, and that's my workaround until I get a more powerful computer with USB3 so I can move on to 1080p captures using the HDFury 2,) PS3 main audio output is TOSLink to my reciever with multi-audio output enabled to goto the component box to output to my PC for stereo capture. For my Wii, I set it to 480i wide screen with component cables and hook it up directly to the component box when I capture. If you are doing it for the 360, just plug the HDMI cable straight into the card and it'll work, it doesn't have all the lock outs like the PS3.

If you are just trying to max the screen and not really trying to record or stream anything, that's easy, just get a HDFury 2 and Blackmagic Intensity Pro, change the firmware to like 3.2 on the card, use graphstudio64(I'm pretty sure you are running Win7 64bit heh,) and alt-enter that shit and you are done without all the complicated shit.

Nice. Now thats what I am looking for...

So you are not experiencing any lag with this capture card? People were saying that about Avermedia one but I sense the slightest latand it just kills my desire to play using the capture card.
