I just have to say, regardless of who is at fault, I find it strange that it has been one year after the nMP release and we still have to experiment to find an acceptable 4K monitor !

Well said. I'm sure we're all feeling like we're risking our money with what is (despite the dropping prices) still an expensive purchase. :(

I take it back

That file enabled more scaled resolutions (that are the correct aspect ratio)...

But I got dropped to 50hz ...

Removed that file and I'm back to perfect 2x 1080p resolution @ 60hz..

Got to be a way to get the scaled resolutions above retina 1080 desktop space working at 60hz.

Perhaps an upcoming Yosemite update will remedy?

Are you on 10.10.2? It's been said that that update takes steps towards fixing it, but complete support is not quite there yet.

9to5Mac: Apple adds new LG 31-inch 4K monitor to list of supported Mac displays.

I have been following this thread for awhile now and appreciate all the info! I was browsing apple support and noticed an update to the list of supported 4k displays.

With OS X Yosemite: -LG 31MU97 4k display (at 50Hz & 30Hz).
http://support.apple.com/en-us/HT6008
I found it a little funny that they actually included the 50Hz:)

Someone from that other MacBlog must be reading this MacRumors thread too, even if they are a few days late. (And not entirely accurate).

The nMP hardware is definitely able to drive two of these at native resolution and 60hz. It seems to just be os support that is lacking at the moment.

Monitor c4K - 3x --> Hz?

The nMP hardware is definitely able to drive two of these at native resolution and 60hz. It seems to just be os support that is lacking at the moment.

Ok, but if mounting 3x LG-31MU97 monitors, then the third one would be limited @30Hz?

WWDC-2013: nMP & 3x 4K monitors.

Three of them seems like a long shot....

Even just physically, how would you mount them?

Well, when Apple announced the nMP (2013), marketing chief Phil Shiller presented images of a motion-picture editing setup with "three 4k monitors" running off the one Mac Pro. (Note, the right side is cropped). Maybe that arrangement would work?

Or - The LG-31MU97 monitor is 29" wide, 16" high. So I guess you could also go vertical if that setup is too broad. (Especially with ISP screens).

It does look like No Thunderbolt.
If you're using a MacBook Pro and looking for a TB display to be your "dock" of sorts (with ethernet/TB/etc) you'll want to keep waiting on something different.

Could you please clarify? I have a MacBook Pro (Retina, late 2013) and planning to buy a 4K monitor. From the Apple support page it's clear that the Dell UP3214Q and ASUS PQ321Q are supported at 60 Hz using MST but I'm now confused as to whether this LG 31MU97 is.

The apple support page says:

With OS X Yosemite, you can use all of the above displays as well as the following:

LG 31MU97 4K display (at 30Hz or 50Hz)

...

Multi-Stream Transport (MST) displays

MacBook Pro (Retina, 15-inch, Late 2013, Mac Pro (Late 2013), and iMac (Retina 5K, 27-inch, Late 2014) computers also support multi-stream transport (MST) displays at 60 Hz.

But then it includes instructions on how to manually configure four displays for MST but not the LG. Does that mean the LG doesn't support MST and therefore my MacBook Pro won't be able to drive it at 60 Hz?

The 31MU97 is not an MST display. It supports its resolution using SST which should be superior. The LG support page mentions that OS X support for 60hz at the native resolution will be in an upcoming update, possibly 10.10.2 as it has made specific steps with regards to this display. Full support may come in the final release of 10.10.2, or it may come in a subsequent point release.

I have through mid-January to exchange my 34UC97 due to holiday return policy, so if Apple can get the issues with this display ironed out by then, I may switch back to it. The picture is gorgeous when it's actually behaving at 4096x2160 @60hz.

Eizo DuraVision FDH3601 - $36k (2011).

Well said. I'm sure we're all feeling like we're risking our money with what is (despite the dropping prices) still an expensive purchase. :(

Right, but three years ago there was only one C4K monitor available (that I can find). The Eizo DuraVision FDH3601 (4096x2160)@61Hz. Running 350W, and Weighing in at 28kg :eek:
http://tech.firstpost.com/news-analysis/eizo-launches-4096x2160-36-inch-display-monitor-20207.html

Obviously, this is a specialised professional monitor, for air traffic control uses etc. And the price has dropped from ~$36k to about half that. But you gotta appreciate that 36½" diagonal (even if the box is bit thick).

Fantastic! What a great bit of research. :) And it's not all that long ago.

Sometimes it's easy to forget how fast our tech moves. I remember being ridiculously impressed when I got my 4096 colour Commodore Amiga 500 to replace my 16 colour Commodore 64 (which in turn had replaced my black and white - and mono - ZX-81). Going back even further I remember the first time I typed some characters on a keyboard and saw the letters appear on the fuzzy green screen in front of me which (at the time) was pure science fiction.

And here I am worrying whether I'll get 50Hz or 60Hz on a resolution of 4096 x 2160. :rolleyes:

Sometimes it's easy to forget how far we've come.

I tried a portrait orientation and these monitors are just too tall for me to use them like that. The Dell 30" displays are perfect for that though.

Two of them in a widened L shape are working great for me. If only I didn't lose all my settings every time the computer turns them off to save power...

LG Page Updated to show Mac support at only 50Hz

Well the LG UK page that many posters mentioned earlier in this thread has been updated at http://www.lg.com/uk/monitors/lg-31MU97.



So it may be very well be that this monitor is limited to 50Hz at 4096x2160. I'm still hoping that it will magically gain 60Hz support, but now that both Apple and LG are stating 50Hz I beginning to doubt it.

For $1399 and without 60Hz support, I started to poke around to see what other options might be available. What seems to be the consensus, if any, on the samsung U32D970Q?

I really like the U32D970Q so far. I'd be happy to answer any questions about it.

Samsung U32D970Q (3840x2160) Monitor - Reviews.

What seems to be the consensus, if any, on the Samsung U32D970Q?
The reviews that I've found are mixed. Some complain about the "grainy" image /coating look etc. But others seem to be big, happy fans. At a list price of $2,050- it's considerably more than the LG-31MC97. And it's UHD, not true C4k. With no ThunderBolt capability and, from what I can see, no Vesa mounting brackets :confused:.

So, probably best to wait (if possible).

I really like the U32D970Q so far. I'd be happy to answer any questions about it.
(Just saw this recent post). Q. Does it have Vesa, do you see any graininess, and is it really worth about 46% more than the LG/C4K monitor? Thx.

Multiple Monitors w/ rMBP via Thuderbolt 2

Just completed the unboxing and installation of the 31” LG. Thus far, a great experience. However, a word of caution.

I have a rMBP Late 2013. I’m connecting the 31MU97 via the thunderbolt 2 connector and I am able to reach the 4096x2160 @ 50hz without any settings changes on OSX Yosemite and on Bootcamp running Win 8.1 However –

When I attempt to connect another monitor to the second thunderbolt 2 connector, under bootcamp/Windows this works fine (at 2560 x 1440 and 60hz), yet under OSX … nothing. Its as if the port is shut off.

Moreover, under windows, I am able to connect a third monitor via the HDMI cable and get a 1920x1080 resolution. (Three monitors working)

And finally, under Bootcamp/Windows I can also get the laptop’s retina display to work (a fourth display) at 2880x1600 – yet doing this causes the 31MU97 to degrade to 3840x2160.

Given this, are there any other owners out there who have been able to get two of the thunderbolt ports working with the 31MU97 and another monitor under OSX? The hardware seems to support this, as Windows is able to drive the displays.

Thanks in advance.

I am looking for a monitor. I just bought a 13 inch rmp this year. Any experience on how this runs on this setup? Is it smooth?

Are you connecting the monitors to different buses on your nMP (see attached)? Apologies if you're already aware of this - I only mention it on the off chance that you're not.

It looks like Charles-C is rocking a (rMBP)MacBook-Pro(Retina)2013, and not an (nMP)Mac-Pro(6,1). Please correct me if wrong, but I suspect that model only runs the one TB2 bus. In which case, his multiple-monitor-menage is quite surprising.
