4k Monitors that just work?

Hey guys, I've been looking around a bit at the different 4k options we have at this point. Are there any monitors that don't use the tile separation to work at 60 Hz? Meaning it's acting as one display and not two. Or do you think I'll have to wait for the new display port standard?

I'm going to be using it for coding and gaming, so I'd like to avoid high input lag/pixel response. I'm probably asking for the holy grail of monitors, but maybe it exists :p

Thanks!
 
For 4K Monitor/TV to just work (SST mode that is) you are limited to 30Hz via HDMI 1.4 or DP 1.2.
Via hacks like DP 1.2 MST mode you can get 60Hz with current 4K monitors and Panasonic UHD TVs, but bugs/glitches in MST implementation of AMD/Nvidia videocards and current monitor firmwares imho are far from 'just work' experience.

For 'just work' one will need - next gen gpu-s supporting DP 1.3 or HDMI 2.0 (none of current GPUs including latest ones like Titan Black/780 Ti/R290X does), so that output device will support UHD 60p via single stream output, not needing to rely on buggy multi-stream implementations usage with current GPUs and current monitor firmwares to get those 60Hz. If you choose this route of waiting, as bonus you will also be able to buy your next monitor/TV for way less then current prices, but of course you won't get them now, rather just in a year. If your current monitor is 1440+p 27" or 30" i advise wait out that year for next GPUs. If you absolutely cannot wait and upgrade for old 720p/FHD display is long overdue, then it's up to you if you choose faiting with current implementations/products. No bugless 'just work', at least for non screen-tearing 60Hz.
 
This plug and play 4K would only apply to AMD cards with 600MHz pixel clockscorrect? As Nvidia cards with their 400MHz RAMDACs have too low bandwidth to send a 4K60 signal.
 
No, your fine as long as your card supports DP1.2. Displayport 1.2 is enough bandwidth to push 4k 60hz, the reason why the IGZO & Dell 4ks need MST is because their TCONs are crap. The new 4ks have beefier Tcons that automatically join the two panels as one so your GPU only sees one panel. No mess, No fuss.

BR2008's got a 680gtx and it pushes the U28D590 just fine @60hz 4k.

Why do you care about 60Hz? It doesn't matter unless you are playing first person shooters, or like watching fast action video at 4K (content doesn't exist currently).

I love my seiki 4k monitor at work and recommend it to everyone.
 
<sigh> church the U28D590 is plug and play 60hz 4k as long as your using displayport. This has already been verified by users who already have the display. As for me, mine arrives tomorrow.

It would be best to let more than 3 people verify that the monitor works before declaring on the Internet that it is "plug and play" aka. works with a variety of DP video cards of different generations under several recent device drivers under a couple of recent desktop OS's.

60hz and 30hz is a huge difference as that is what most standard monitors have trained our eyes to see over the years in any type of games

The Seiki 4k is a great value and its VA picture quality is excellent....only thing it needs is 60hz and Sinuhet may be able to make that happen!

Well I have the display now in my possession and it runs 4k 60hz perfectly on my 290x and Titan GTX, if thats not enough for you then, well...I dont care really :)
 
My Samsung monitor works perfect too. Completely plug and play. Games work as well in 1080P as they do in 4k too.
 
Does the Samsung operate in MST mode or SST? Or does it auto-switch between the modes?

30Hz vs 60Hz is a big deal for most people even in mundane desktop work. Some people don't notice or care that their display is running at only 30Hz, but others (myself include) can really sense the stuttering of 30Hz.

Also, fast action video at 4K wouldn't need 60Hz unless it happens to be 60Hz content or you're using software to frame interpolate.
 
Stutter =/= flicker.

30Hz is really really obnoxious. If you don't notice it then more power to you but it seriously degrades useability for those who notice when things jerk across their screen.

120hz isn't even seamless motion for things as simple as moving a window around on your screen. 60Hz is definitely useable but kinda unfortunate. 30hz is pretty much an insult :p

However, it's much like Anti-Glare coating in that some people couldn't care less and/or don't notice, while some people would prefer to claw their eyes out over using a display with it.

What frame rate do you get with a flight sim? Typical is 24Hz. Movies are 24Hz. People don't complain about jerking across the screen with those.
 
Another misconception.

Hz =/= FPS. Movies operate at 24FPS yes, and they look FAR FAR SMOOTHER on a 120Hz screen over a 30Hz screen (simple math, 120/24=5 whereas 30/24=5/4 which means that every 5 cycles you see four frames plus a repeat which looks jerky). Regardless, 24fps also sucks, hence the push by the more progressive parts of the movie industry to 48fps.

Also on the games I play I get 150-200FPS at 1440p.

I've never hear somebody say that movies ghost or otherwise look "lagged."

Most of what people complain about in movies is jaggies and artifacts which result from the 5/4 pulldown you mentioned.

But a 48Hz set and a 120Hz set should appear identical when playing 24fps content.

I do have to say that the motion blur in movies bugs me at times. That is how they get around the low frame rate...

If your monitor is currently at 30 fps I guess you won't be able to tell the difference but the difference between 30 and 60 is night and day.

On topic:
Any other monitors people recommend? I like the Samsung, but I curious for the different options.
 
If you use a 30hz monitor by itself for a while, your brain probably convinces you that it's totally normal.

If you use it beside a 60hz monitor, or you switch a monitor between 30hz and 60hz, you can immediately see the disturbing horribleness, though. Even just on the desktop.

I've been on 30hz for a while because of buggy AMD drivers. On the desktop it's pretty normal, but there's too much input lag in games, not very fluid. I haven't been gaming as much as I'd like.
