Is there any practical way to drive this from a Linux-based laptop that doesn't currently have an appropriate video card / output? (I don't consider "buy a new computer" to be a helpful answer: I'll be ready to do that in about 18 months. But I'll understand if the correct answer is "no." :-)
Well things that can't drive it at 4k: VGA DVI HDMI 1.3 or lower. Things that can drive it: HDMI 1.4 at 4k@30Hz HDMI 2.0+ at 4X@60HZ except they didn't put that on the monitor in this case, so that's not an option. Displayport 1.2 MST at 4x@60Hz I think Displayport 1.1 could do it at 4x@30Hz but I am not sure. So if you have any displayport, you might get 4x@30Hz, or if you have pretty recent HDMI you might, but otherwise you can't. In theory a dual link DVI to displayport or hdmi 1.4 adapter would be able to give 4k@30Hz, but as far as I can tell no such device has ever been made. -- Len Sorensen
