Mac Pro 2012, GTX 770, OSX 10.8.5 and 4K monitor

Hello MarekO,

I hate to tell you this, but with the model of Mac Pro that you are running, you would not be able to use a 4K monitor. Take a look at the article below for more details.

Using 4K displays and Ultra HD TVs with Mac computers

Can you narrow down displays you are thinking of and in your price range?

Dell, Asus, LG, Samsung - along with this ASUS are also some other 4k displays listed for comparison.

The one article with 5,1 was using AMD Radeon R9 280X 3GB

can't see why GTX 770 would not (unless Mountain Lion issue and you need SwitresX?)

Some of Apple's articles I wonder if they are written by the marketing department instead of tech (and whoever does, they should have an engineer to proof-read)

MarekO I do recall your name from before, just not the particulars.

Apple never updates specs on maximum memory, hard drive compatibility and other things. Even the fact that the ATI 5770 worked in any and all Mac Pro models outside of audio support, which was a godsend to many like me with a 2006 1,1.

Someone wrote that one GPU required 800MHz DDR2 (mine came with 667MHz) so people wanted to just swap the memory figuring that was what the graphic card needed. Nothing to do with memory speed. Everything to do with EFI 32 vs 64 (and no mention of UEFI or the more accurate and technical).

Okay

Did you read where the ASUS monitor customer had trouble? and that a firmware upgrade helped? Notice also the horrid customer support they first received and how miniDisplayPort vs DisplayPort?

I am sorry I don't have more experience or own a 4k monitor 🙂 Would like to, sure.

There have been - especially a year ago - there was a lot of "hand-wringing" over which brand and models of 4k would even work on a 6,1 - let alone work with GTX 770 (which is supported on your Mac when running Windows btw in 4k mode, so there!)

Here is help and to wet your appetite:

Anyhow, can't help but be reminded today when I discovered how to enable 60Hz 4K MST on Nvidia cards. Seems Apple didn't want the cMP rubbing elbows with nMP so took to some more deliberate knee-capping. (how Kerrigan-esque !)

I put the Asus PQ321 in MST mode and Nvidia GPU can output 3840x2160. And if I run the "OpenClOcenawaves" bench, I get 61fps. Anyone familiar with this app knows it has been locked to refresh rate for last 2 OS builds. You can unhook it with Quartz Debug, but for my purposes, better not.

Exciting stuff!! Though to be honest I had no idea we couldn't already plug a 4K display into our cMP's and get 60Hz support. I thought that was what they fixed in 10.9.3?

Only on AMD cards, been there since 10.9.2 I think. They stacked the deck against Nvidia, they have been limited to 30Hz. Artificially as it turns out.

SST displays are a different story.

........ ......

Suddenly it's 1984 - Nvidia 4K 60 Hz support is there, Apple turned it off ( 1 2 3 4)

MacVidCards

So AMD vs NVidia stuff. And can't cannibalize AMD on cMP without also damaging Dxxx so the R9 280x and above are a safer bet.

People have been (trying) to tell me that the CUDA vs OpenCL is "history" and not as big an issue (though AMD drivers and Adobe apps on nMP 6,1 and those Dxxx's are (or have been) a real issue for the last year. It can take 12-18 months for changes, to make their way into the market and next Adobe upgrade. So they have had their year!

The system is 10.8.5.

Support that you need was included in 10.9.3+

One more "pet-peeve" is graphic drivers. Only bundled in OS, no support for last year's OS.

Works on GTX680 as well....even a GT640 w/DP can do it. Darn Apple and their forced...everything

Included cables not supporting features dept:

if you plan to run the (LG) 31MU97 at 4096x2160 60Hz, you will need to buy a heavy gauge high quality display port cable($50-$70) because the one they provide flickers and blacks out from time to time cause it's pushing the data limit. It's kind of funny they give you a cable that wont run monitor at it's full spec...

" Dell P2715Q should work with no issues since it's running SST.

" I have tried the LG 31MU97 and the Samsung 32"4k with the 680 and had no issues getting 3840x2160 60hz working with plug and play all the way back on 10.8.5 through 10.10. "

-----------------

I imagine that Nvidia is like us in that they are overwhelmed by the variety of different 4K displays and how many of them seem to act differently despite in theory adhering to same standards.

I have heard from someone with a Dell UP2414Q who says that the 4K fix still works on that. It is possible that Nvidia has only tested on that and those of us with other displays are just out of luck, at least for 10.10.2

===============

More variables than x and y it seems.

Get out spreadsheet to cover display monitor, OS, GPU

For me, go AMD so you can see and use your 4k display - in an ideal world, people have used AMD for display monitors and left GTX or Quadro to handle the CUDA / GPGPU workload which has worked just fine. Only issue Is the measly 2 x 6-pin aux power provided natively.

Only if you:

- previously "purchased" Mavericks. If so go to the Purchases section of the Mac App Store and doewnload the installer. Then make bootable USB install device and boot to that device and format the startup disk and install. You will get 19.9.5

- You have a backup made with Mavericks or a clone of a Mavericks installation. Just retore from the Mavericks backup or format the existing HD and clone it from the clone.

Barefeats on 5k but of course 10.10.2 with a GTX 980 ($600+)

http://barefeats.com/mpt5k.html

The only pro app not happy was After Effects CC's ray-trace 3D which gave an error when we loaded the Robot project.

That appears to be an Optix issue, not a 5K issue.

WHERE TO BUY THE GEFORCE GTX 980 and other GPUs
You can buy a 'vanilla' GTX 980 on Amazon.

For a modified GTX 980 with Apple startup screen, visit MacVidCards.

If you favor an AMD GPU like the Radeon R9 290X, MacVidCards can modify it to run at PCIe 2.0 bandwidth in your Mac Pro tower.

It does not run at 5K on the Dell 5K display but it does run at 4K (60Hz) on that display.

Some Macs can only go to 10.6, others to only 10.7 All the rest can go to Yosemite. Thus there is no reason to be able to upgrade to 10.8 or 10.9. at least in Apple's opinion if you did not have 10.8 or 10.9 previously
