Too expensive for now, but I'm sure prices will go down way faster than two years. It's one of the very first 4k monitors, they're asking for a premium. That won't last long, hopefuly And I'd prefer something like 24"-26".
it's the pixel density that makes it cost that much smaller pixel = greater error rate x area of screen = failure rate / component, so it's simply much more expensive to make at the moment + IGZO is more than AS (ingium gallium zinc oxide) (amorphous silicon)
Speaking of user interface, I read on the forum they are thinking of doing a window-in-window type of thing to help keep track of all the bases. Making a mini-map sized box that shows a view of any part of the map you want without the need for multiple monitors. I wish other rts games had this feature.
