I'm an avid user of multiple monitors and have been contemplating an upgrade to a couple of 4k monitors. However I'm not sure how to interpret my video card specs or the specs of other cards I might have to get. Most cards specify the maximum resolution, but it isn't readily apparent whether this is per display or an overall maximum renderable area.

For example I have a card based on the GTX 650 Ti chipset that claims to be able to drive 3840x2160 at 30Hz. This is the size and speed of the monitor I was looking at—bit while my card has four outputs, somehow I wonder if it is up for driving 2ea 4k displays. Would that spec resolution be per-display or an overall total across multiple displays?

I'm sure there are exceptions to this depending on the system, OS, and approach used in general, but I'm going to have to go with, as a general rule, saying that resolution is on a per display basis. I remember using a 19" CRT running 1600x1200, with a 15" @ 1024x768 way back, having two gfx adapters with Windows 2000.

    Your anecdotal evidence is exactly the opposite of what I'm asking. I have one GFX adapter, and in fact a typical way of using the DVI ports on these sorts of cards is in a dual-link configuration. – Caleb May 17 '15 at 18:46

    @Caleb I did the same with a single GFX card with two outputs, and I was able to set individual resolutions for each of them. – Jarmund May 17 '15 at 19:06

    up to a total the max speced res of the card on each port or up to a total where the overall rendered area is less than the total max spec? – Caleb May 17 '15 at 19:11

    @Caleb I cannot say, my resolutions bottlenecked at both of the screens. I think I remember the card advertising up to 2048xSomething – Jarmund May 17 '15 at 19:16
