4k monitors are not that rare/pricy. You can get pretty cheap 60hz ones from Asus and the best ones from DELL. Problem is that most consumers who would buy those monitors would expect every application to run on it without problem, that includes games and for that you need to spend a lot of money on GPUs.

I'd say the real problem is the fact that the affordable ones you mention, tend to have terrible specs apart from resolution (and latency). Low contrast, bleeding, terrible colour representation. At least that was my experience.

Before anyone goes jumping on the "best ones" from Dell, take a read through this 35 page support discussion about their UP2414Q: http://en.community.dell.com/support-forums/peripherals/f/3529/t/19536443?pi23185=35 http://en.community.dell.com/support-forums/peripherals/f/35... Anecdotal, but a friend and I both have problems with ours, and he got lucky with the 1.1 firmware revision (Dell won't let you upgrade it, you have to go through support for a replacement, and they'll send you a refurb that might have the newer firmware because they decided it would cost too much to update their existing inventory). And even then it might not work. He's waiting on Dell Support for his 3rd unit. Do yourself a favor and wait until DisplayPort 1.3 is widespread and can drive a 4k screen without using Multi-stream Transport. It's not worth the headache. Right now my computer is convinced that the left and right halves of my screen are separate displays and nothing will convince it otherwise. Other times MST will fail to connect and it only picks up 1/2 the resolution in the middle, with 1/4 width black bars on the left and right. From what I remember reading, Dell botched the DisplayPort handshake, and the workarounds that AMD/Nvidia have put into their drivers to try and fix it aren't 100%. I need to return mine for backlight flicker too. But I'll write that off an an excusable manufacturing flaw that's going to pop up occasionally on some number of any model. EDIT: Just for perspective, this is a screen with an MSRP around $1100, though we both bought ours on sale. The amount of shit we're dealing with for a screen that expensive is not reasonable.

  UPDATE My friend's 3rd display just came in this afternoon. When he plugs it in and turns it on, the computer stops responding. When he turns it off, the computer resumes working normally. Ordinarily I would scream "driver problem" at that one, but the 2nd screen did not have this problem with the same GPU and driver installation. (That one just randomly disconnected and reconnected every 30 seconds or so) He's trying it on different computers next, further updates as events warrant... UPDATE 2 Hooked up to his Mac. It flickers on and then goes blank. Even running at 30 Hz on single-stream transport, it doesn't work over DisplayPort. HDMI works at 30 Hz, but DisplayPort 1.2 with MST is the only option with enough bandwidth for 4k at 60 Hz.

  > Do yourself a favor and wait until DisplayPort 1.3 is widespread and can drive a 4k screen without using Multi-stream Transport. It's not worth the headache. It reminds me of getting an external monitor for my T420 from Dell and seeing that DisplayPort to DisplayPort 1.2 cables are practically non-existant. I ended up getting one after hours of search online, the only proper manufacturer of these being Lenovo itself. I wonder if the situation gets any better...

    I was under the impression that DP's cables have all been backward compatible, and a 1.0 device could just plug into a 1.2 screen and work. Not the case?

  I have my UP3214Q working just fine. You need to A) make the SIMULATED_* monitor settings match the 4K ones; and B) use an HDMI cable along with the displayport cable.
