    Running 8 TV's

    Hi guys

    I need to build a machine to run 8 monitors for running different pictures for an estate agent.

    I was thinking of using 4 low ends gpu's but I know these will be very loud.

    What I need to know is will 2 Nvidia 660 run 8 tv's between them?

    I take it that they should not be put in SLI. Their website says each will run 4 displays, VGA and hdmi isn't an issue but how do I use the display output, adapter?

    Thanks for any help

    Not if they're passive :-) Maybe worth investing in a couple of quad screen workstation graphics card rather than normal 'gaming' cards. You only need 2d so a 660 would be overkill.

    Re: Running 8 TV's

    Would something like 4 gt610 passive be enough? With 4 in, would they not creat a lot of heat?

    Just so I understand the tech, would 2 660 run 8 screens in windows 7?

    Re: Running 8 TV's

    So. Welcome to amateur Digital Signage.

    Is framerate a concern, or do you need a mostly static display (e.g. powerpoint)?

    Is there a need for much range between the screens, or can you get away with all the screens being physically near the control box?

    You may find USB monitors (or USB graphics cards) a scalable solution - really you want a network-based box, but that can get complicated

    Re: Running 8 TV's

    directhex makes a good point, USB could be a good way to go. Two 660s is almost certainly overkill unless your customer is going to be demoing 3D representations of the properties.

    I'd say get the 610s, four of those will cost a lot less than the 660s and the noise and heat are tiny with the 610s, even the active cooled ones. Their max TDP is about 30W and will operate much lower than that most of the time given the likely use case. Choose a noise dampened case if noise is large concern, there are a number of good ones for not much money. Otherwise tuck the system away in a carpeted enclosure but don't forget ventilation.

    Re: Running 8 TV's

    My client wants everything in one case. If I was to run 4 610's I take it I would need a high end mobo with 4 pcie slots like the
    Asus Z87-WS s1150 Z87 Workstation Motherboard?
    The budget is high enough for this board.
    I take it that I don't SLI the cards, just run them indipendantly?

    you'd need one with 2 displayport outputs and you'd need expensive active adapters or monitors with native displayports. Nvidia has a big benefit at the minute in that you can run 4 monitors natively regardless of outputs. And 4 low end cards is still cheaper than 2 7770s.

    I can offer an alternative, however:

    buy two of these: http://www.ebuyer.com/451860-sapphir...i-11190-12-20g
    This is a sapphire Flex Radeon 6450 - it uses 2 DVIs and an HDMI to power 3 DVI monitors. Add them to an AMD motherboard with onboard graphics and two PCIe slots (like this one: http://www.ebuyer.com/280209-asus-f1...ard-f1a55-m-le) and you can use the two graphics outputs from the onboard graphics alongside the three from each Flex card to get 8 outputs. Probably the cheapest way, as you don't need the expensive motherboard with 4 PCIe slots.

    Thanks for your help with this.
    There is a good budget for this sytem and I have been asked for a highend i7 1150 with 16 gig of ram so I think the 4 gt610 with this mobo should do the trick:

    how hot do these cards run? would passive cooling be ok?

    Why? What's the system doing?

    I understand that management tend to think they know what they want, but if you can turn round and say "actually, you can do the whole thing for half that budget" you'll get props for saving people money and they'll get a system that's suitable to their needs. If there's a good operational reason requiring the extra performance that's fair enough, but really you need to consider what the system will be doing, creating a suitable specification for that, then checking it's within budget. Not setting a budget, then building a system that costs that much, just because you can...

    I understand your point but they are a small company which im doing a favour for. They have said that they require this performance for what ever reason. I agree thats it seems overkill for what they require but this is what they want. I'm not sure if thier marketing team will also be using it so its up to them really.

    I just need to know how hot these cards run?

    Re: Running 8 TV's

    Not hot at all as long as you keep the case well ventilated. Most GPUs can happily go up to 80*c but nVidia have stated 102 on their website as the max. Unless you do something really silly, I don't think you will hit that with a 610. I haven't spotted a case mentioned yet. Are you given one or are you going to get one? Whatever case you get, I'd say at a minimum you need 2x120mm intakes and 1x120mm exhausts. My preference would be 2x120mm front intake, 1x120 bottom intake and one top and one rear 120mm exhaust. With that, you can run them all at very low RPMs with Asus' Fan Xpert but still cool effectively in silence.

    I'm a sucker for Fractal Design with their clean cases and silence focused Define series.

    I've seen a 610 for sale somewhere with 4 outputs..
    2 of those maybe?
    Here it is:

    Not sure this is quite what the OP is after. having read a few reviews it looks like this will drive 4 monitors, but it will extend A+B and C+D rather then having 4 independent screens
