btarunr If it wasn't for the 1080p dark-ages (2005- date), 3840x2160 would be mainstream.

But this isnt about what could or couldnt happen before. This is about what is happening, what is available, and what is possible to run. Sure we might only be 2 or even 3 generations away from running 4K monitors on single or dual GPU's, but thats still perhaps almost 3 years away, and people can barely afford to run on 1200 plus resolutions on the current GPU's of today.Either these 4K screens drop significantly in price within 3 years (to within 1200 or 1440 monitor prices of today) and people are able to buy pretty high end systems to run it, or they simply arent going to sell except to those 1% of enthusiasts with money, or oil barons with cash to splash.Sadly we're in the situation now, and 1080p is still mainstream because the hardware available just isnt fast enough to warrant such a jump from 1080p to 4K to anyone except those with money. They need to work on getting IPS 1200+ monitors cheaper, or their precious 4K technology will fail, and they'll blame consumers for not needing it, when in actual fact, they just pushed it too soon.Dont get me wrong, I'd love 4K, for everyone, used in everything. But we're not prepared for it. We cant afford to run it. Not to mention they used 2 PSU's to run 4 titans on the monitor...
