I wonder whats the better option for replacing my 2x 24inch Dells (total resolution 3840x1200) 1) Get one 40 inch 4k monitor to have one giant display with about the same DPI but more screen real estate and no bezels 2) Get two 28 inch 4K displays for super high DPI but less screen real restate and bezels.

Keep in mind, when the resolution the same, your screen real estate is the same with different sized monitors. If you have a window on a 4k screen taking up 25% of your screen, it'll take up 25% of the screen on a 28 or 40" monitor. But it's physical measurement would be larger on the 40" screen. But you still can't fit more things on the 40". Go for the dual 28" monitors, then you really get 2x the screen real estate, and have the benefit of dual monitors.

"MacBook Pro (Retina, Late 2013) and Mac Pro (Late 2013) computers can use 4K displays and Ultra HD TVs with OS X or Windows (via Boot Camp)." http://support.apple.com/kb/HT6008?viewlocale=en_US&locale=e...

(Note that according to that page, the MacBook will only do 30 Hz.)

60 if display port is available (which it is on this Dell).

> who will sell me a GPU with three DisplayPorts to drive three of these? Visiontek makes a couple of eyefinity cards with 6 mini-dps. I didn't see the measurements but it doesn't look too long. http://www.newegg.com/Product/Product.aspx?Item=N82E16814129...

I so want to believe you're right, but I don't see anything on that page that suggests those DisplayPorts can drive 3840x2160. The footnotes imply, but do not say specifically, that 2560x1600 is the maximum resolution supported by each port. Am I wrong?

All the 7000 series Radeons and many of the earlier ones support DisplayPort 1.2, which gives them enough bandwidth per connection to handle 4k, and the total pixel count of 3 4k displays is only slightly higher than 6x2560x1600. The 7000 series Radeons increased the maximum dimension of an Eyefinity array from 8k to 16k, so 3 4k monitors in any rectangular layout should work.

Excellent. Again, a big thank you to Seiki for dropping a bomb on the display industry, whether or not Dell acknowledges it. 3840x2160 at 28 inches is quite fantastic. A step closer to 10,000+ horizontal pixels in a single ~50 inch display, which I consider an ideal for desktop computing. The burning question for me right now is who will sell me a GPU with three DisplayPorts to drive three of these? The top-end nVidi…

+1 for the idea of the single 50inch 16K display. I also would love something like that, running a single 40inch 4K display should be possible quite soon and would give me roughly the same DPI as my current 2x 1920x1200 24s.

But since im a coder, separating windows in different monitors might be better than using one super large display with windows cluttered everywhere, but id be willing to try.

What to you use your displays for ? A display like that should be epic for video/photo work.

yep, thats looks about right but its not sold in europe and only has 30hz afaik, other than that its a pretty good deal.

This[1] one is 500 US dollars and is 120. I don't have access to non U.S sites here at work apparently so I can't be certain they have it over there or not. [1]- http://www.amazon.com/Seiki-Digital-SE39UY04-39-Inch-Ultra/d... Edit: Sorry, didn't catch that it only does 30hz through HDMI on the specs, and didn't realize it until I read the limitation downstream. Dang...

For coding, you might not notice it as much. I run my 27" monitor at about 30 hz, and it seems Just Fine. Youtube looks okay when not full screen, but frankly I use it for editing code, and I happily trade the refresh rate for the increased resolution.

Any idea how new of a macbook you would need to power this? I'm guessing my 2012 13" air can't run it right?

You can drive 4k with a recent macbook, but it's laggy as sin. My Amazon review: http://www.amazon.com/review/R4OJ5D5RPILCH/

Thanks for that note. I was at the Apple store in Pasadena this week checking out a new rMPB (OS 10.9.1) and the Sharp 4K monitor. They connect by HDMI, not DP, at the moment. This limits refresh to 30Hz.

I did not notice the lag on text input that you did (but, I did not enter much text; I didn't think of this as a possible issue). I also did not notice any significant lag with the mouse. This may be user-dependent.

The thing I did notice is poor rendering of some fonts. There were colored fringes around the system font that both the Apple rep and I noticed. Other common fonts were affected as well, but not all of them. It seemed like a problem with subpixel rendering to me. Changing the display mode to mirroring did not help.

The Mac Pro did not have these problems. It's quite smooth (60Hz) from the Mac Pro.

It was bad enough that it disqualified the monitor for me. I assume it's an artifact of the HDMI driver they're using, and "probably" fixable with a better driver. But you never know.

Even a brand-new Macbook would be unable to power this display. All currently sold Macbooks can only power displays up to 2560 by 1600; the Macbook Air can power one external display at this resolution, and the Macbook Pro can power two. (Edit: The iMac can also only power one additional display at the same resolution.) If you want to use a Mac with a 4K display, consider getting a Mac Pro, which can power up to thre…

I think you are wrong here.

I've used a late-2013 rMBP with a 4K monitor (OS 10.9.1) at 30Hz. It's a supported configuration (http://support.apple.com/kb/HT6008?viewlocale=en_US&locale=e...).

How big a window is on a certain resolution depends on the DPI scaling. Screen real estate would be roughly the same, but everything would be much more crisp with higher DPI.

So with 2x 4K 28inch screen the screen real estate would be about the same to my current setup but everything would be sharp. Whereas with a single 4K 40inch screen i would get double the vertical space than my current setup and roughly the same DPI on a single monitor. It like 4 of my current Dells melted together into one giant monitor.

You're looking at top-end desktop geforce, but in this case you probably want top-end workstation nvidia cards: http://www.nvidia.com/object/quadro-desktop-gpus.html

Quadro K6000 for example has 2xDP + 2xDVI available. It's probably not something you want to buy for home though.

Something to keep in mind is that this is effectively a Windows monitor, not a Mac one. The reason for this is PPI: Most Apple displays are in the 100-110 PPI range, with Retina Display Macs doubling that to 220 PPI. At 28", a 3840 x 2160 panel has a PPI of 157, which sits right between Retina and non-Retina densities. This means that on a Mac, you’ll have to use it one of two ways: Either at 1x, where the higher PPI…

While certainly not ideal, you can probably use this with a Mac with no issues and turn on scaling. It won't be a native resolution of the monitor and wouldn't be great for day-to-day use, but if you hook your Macbook up to a monitor every once in a while it should be fine.
