4K capable video card

[spdfreak]

We are installing a couple of 4k monitors to view the video feeds from 5MP surveillance cameras so I need to pick video card that will do 3840x2160 to 2 HDMI outputs. No gaming, just desktop apps... any suggestions?

IGPs will do that.

I don't understand why you would need 4k monitors for 5MP surveillance. That makes no sense..

The camera resolution is 2592x1944 so we need something better than 1080p. The customer wants to be able to see full res video.

From AMD's website, it looks like the 7xxx series and above support it but a search on NE only shows 2 cards- both Nvidia. Plus I need 2x HDMI. Each computer will run 2 monitors.

Look for display ports and use a HDMI convertor.

your specs dont entirely jibe. 4k requires 2hdmi for 1 monitor. are you driving 2 4k monitors on each computer? to drive 2 4k monitors on 1 machine with hdmi you would need 2 video cards or a card with 4 hdmi ports(which i dont think exists).

either way a single displayport cable would be cleaner. and doable on one card.

I didn't realize you needed 2 HDMI's for a single monitor- is that a card limitation? The monitor doesn't require 2 HDMI inputs so I'm not sure how you would even connect it. But, if display port is easier, that's no problem as long as the adapters work.
edit- none of the monoprice adapters do better than 1900x1200, so that won't work.

nvm i thought you were using 4k monitors, the seiki is a tv. 4k monitors usually have a displayport input. a single dp cable can do 4k thru mst but there are no adapters that will split out the 2 streams in the dp bus into 2 hdmi.

you will probably have to use 2 cards per pc.

this review says that HDMI 1.4 supports 4K... the question is whether it supports dual 4K monitors.

"In that short preview we validated that both NVIDIA and AMD current generation graphics cards support output to this TV at 3840x2160 using an HDMI cable. You might be surprised to find that HDMI 1.4 can support 4K resolutions, but it can do so only at 30 Hz (60 Hz 4K TVs won't be available until 2014 most likely), half the refresh rate of most TVs and monitors at 60 Hz."
