OS X 10.10.3 Now Supports Dell's Dual-Cable 5K Monitor on Retina iMac and Mac Pro
- Thread starter MacRumors

- Sort by reaction score
It was arstechncia if I am not mistaken, but they were running a preview version of OS X, not the final 10.10.3. So I would want an independent confirmation of their findings before I believe that the MB can't run 4K@60fps
Ain't that the truth.
Intel hasn't felt the heat in a while; AMD needs to step it up -- and even that prospect is nothing but rumors.
And what is driving me crazy is that underneath all of this swirling battle between TSMC, Global Foundries, et al, is the growth of Samsung.
I was hoping Apple's interest in TSMC would push all of this forward faster, but alas, no.
Samsung's continued push into the Foundry business , their overall size and volume, which gives them power with manufacturers, and their history of sketchy business practices makes me think that Samsung has the industry by the balls right now and is squeezing hard.
Is there any reason to anticipate that DisplayPort 1.3 will require Skylake or is it more just a matter of the timing of the new technologies being available on new machines around the same time?
In other words can we expect to see Nvidia and AMD future generation graphics cards being released with DisplayPort 1.3 that are compatible with non-Skylake machines?
I am torn as to whether or not to jump into 5k land on my cMP now with a two cable solution or to wait it out until the release of DisplayPort 1.3 which will have a cleaner 1 cable solution. The single display cable seems likely to maintain more long term compatibility with other devices as the technology gains more widespread adoption following its release.
nMP(6): 2x 5k(Mst) Monitors /$5k.
As others have said, good question.
The (10.10.03) graphic specs seem to indicate that the most recent iMac can run one(1x) 5k external monitor - via two TB2 cables (Mst). But the nMP(6) has 3x Thunderbolt Controllers. So it should be able to run two of them. Perhaps..
But first, you'll need to find another $5k - required to purchase two of the UP2715k screens from Dell. http://accessories.us.dell.com/sna/productdetail.aspx?c=us&cs=04&l=en&sku=UP275K3

Picking up that idea... If that second iMac could then serve as a server so you get some decent use out of the CPU that you paid for...
And anyway, if you have two displays on your desk, you would like them to look identically.
I have to agree. I was thinking of getting an non-apple monitor when I get my new Macbook Pro (which I hope supports 4K), but for $2500 that monitor needs a facelift before I lay money on it.
That means via HDMI, more specifically the HDMI port of the USB-C Digital AV Multiport Adapter you are limited to 30 Hz.
There is no way using only Apple products. But using a third-party USB-C to DP adaptor it is possible. Google has announced such a product but seems to have withdrawn it again.
I think 24" is a good sweet spot for 4K. Still keeps it around retina at typical viewing distances. Too bad my 2012 rMBP can't run 4K at 60hz. I don't much find myself needing a MacBook nowadays anyway, so might as well get the Skylake 5K iMac when that comes out. I'd love 99% Adobe RGB but I've been making it for years without it. If I'm sharing online most people only have sRGB capable screensand even those often don't cover 100%. Only reason I'd need Adobe RGB is for printing out my Adobe RGB photos which is what I've got my cameras set to, and when I do printing I just do 4x6 test prints and check them under a daylight balanced bulb and color correct manually. I don't do a ton of printing, but I do it myself and it turns out looking great. Still wish I had one, but at this point I can't justify buying something like that AND a 5K iMac, lol. I guess I could go the Mac Pro route, which is something to consider, and could save money over time with upgrades. Hmmm.
Pity the editors here don't read the forums.

if anybody is using dell 5k monitor with mac pro 2013 please post your experience. I would really like to know how well this works now that it's officially supported.
This is why I woulds stay away from this display dispite that long thread on this forum.
Rather strange, how can a 1.1 Ghz Macbook run a 4k display at 60hz where a 2.6 Ghz 13-inch Mid 2014 Macbook Pro can't? Anybody an idea?
This has been asked a quintillion times on the MBP board, Apple is skipping Broadwell, as are most for the more powerful machines. Next 15s will be Skylake, followed a few months later by Skylake 13s.
Why did apple forget the late 2013 GT750M MacBook Pro? Anyone know a way to get this to work. Annoys the hell out of me when apple force obsolescence. Especially when there is no dam difference between the mid 2014 and late 2013 in terms of graphics capabilities

Referring to SST unless it does work and there is something else wrong with my set up.

I'm in the same boat and realized that I should absolutely stay away from any dual cable hacked up monitor situations.
So many possible headaches, including the panels not perfectly matching and being noticeable at times.
It's just a stop gap and a good thing to stay away from I finally concluded.
Dell 5K on Mac Pros
I have the Dell 5K display running at 5120x2880 60Hz on the nMP using the dual mDP to DP cables that come with the display. It exhibits the Retina effect scaled to 2560x1440 -- identical in quality to the iMac 5K sitting next to it.
Also works with the 2010 Mac Pro tower with the Geforce GTX 970, 980, and TITAN X.
Wish Apple offered their own version of the 5K display. I have to say this is one of the nicer looking Dell displays with height adjustment and option to pivot to portrait mode.
