    It does seem like Chroma subsample enters in effect automatically... I just tried yesterday by connecting my laptop and selecting 4k 60hz. I saw a slight reduction in image quality, but it did seem to run at 60hz.

    What I need to find now though, is if there is a way to force it. I noticed that some games were unable to run stable at 4k 60hz as the TV displayed weird color artifacts that went away at 1080p 60hz, or 4k at 30hz.

    Uni engine Heaven though, did run without artifacts (though granted... my SLI 980m barely mustered between 18 and 38fps haha)

    All of the output can handle 4K but HDMI can only run it at lower frequency, so they should be able to accommodate your requirement.

    Oh the trick is, nVidia enabled 4k at 60hz with HDMI 1.4 via a trick of chroma subsampling, reducing the image quality and thus the bandwidth needed to maintain the image. It does work for windows as I have tested, fully working 60hz at 4K, but with a slight drop in image quality. I assume there is a way in the nvidia control panel to confirm or reduce the image setting, to ensure games work as well, but I have yet to find it.

    Both mini displayport adapters should work though. I was just testing because my TV is HDMI 2.0 and it does work despite my laptop outputing via HDMI 1.4, using the provided cable and port of my TV for it.

    I'd recommend using mini display output for gaming, but HDMI works well for... working hehe.

    Thanks for the detailed response.

    I primarily want the 4k triple setup for desktop workspace. So 30hz doesn't matter too much then right? Or does only one monitor run at 30hz while the other two are at 60hz?

    Let's assume I do try to game. I can just have one of the 4k monitors enabled at that point right? And if I go with a Gsync setup it should in theory be fairly smooth in a game that isn't too demanding?

    You are welcome! If you see my more recent post, you will see that due to chroma subsampling, HDMI 1.4 does output to 4K 60hz but with reduced image quality, or at 30hz full quality. The other two monitors could run at 4k 60hz independently, without issues. You could have all 3 running differently, no problem.

    Yes you can game on a single monitors, and the rest showing something different. In theory yes, though I am not sure this machine supports Gsync, maybe we need to confirm that first, but it most likely support it. And yeah, games that are not too demanding should run fine at 4k :)

    Unless you enable nvidia surround, you won't use all monitors to game simultaneously.

    Yes it will support G-sync :)
