Follow these steps to use the display's built-in controls to enable this feature: Sharp PN-K Dual-cable displays Some displays with resolutions higher than 4K require two DisplayPort cables to connect the display at full resolution: If you upgrade from Windows 8 to 8.
To get the best graphics performance from your 4K display, connect the display or its adapter directly to your Mac, instead of connecting through another peripheral or device. Published Date: Sat Nov 17 It wasn't until hardware makers and developers realized the untapped processing potential of using GPUs to do much of the work traditionally handled by the CPU that having a strong graphics card became a factor for video editors.

That's why it may come as a surprise to many that just as GPU performance started to matter, Apple decided to release a workstation in which the GPU apparently can't be upgraded. In the past, the fact that the GPUs could in theory be upgraded in the Mac Pro was kind of a moot point—high-end Quadro cards notwithstanding—since next to no officially supported after-market graphics cards were ever released.
Apple seems to have anticipated this concern and met this challenge by offering you as much GPU processing as you could possibly want out of the box. Of the three, the D and D options will probably be the most interesting to video editors. How much RAM will matter is an open question. At the moment, 3GB is probably more than most programs you'll want to use can even take advantage of. However, preliminary tests running Final Cut Pro X indicate that this program at least will greedily consume as much RAM as you can throw at it.
Regardless of what is true right now, it is clear that as the number of GPU-aware applications spreads, we will see a corresponding increase in the amount of RAM these applications are able to use advantageously. So opting for 6GB may not be a bad investment, with an eye toward the future. Simply to drive displays for the purposes of video playback, as opposed to rendering 3D video game graphics, isn't all that taxing. Even many consumer-grade Radeon gaming cards can power 4K displays and even drive 16K x 16K video walls made up of up to six DisplayPort monitors, thanks to multi-stream transport MST technology.
Bandwidth is actually a bigger limitation than processing power when it comes to total display resolution. It's mathematically intensive tasks, like rendering new frames of video after effects have been applied, transcoding, or creating 3D animations that can really profit from a powerful GPU—or two! Certain applications, such as Blackmagic DaVinci Resolve, have been able to use custom multiple GPU configurations for a while, but there has never previously been across-the-board GPU load balancing on the Mac platform.
What this means, for the moment, is that unless you are using applications written specifically with two or more GPUs in mind, one of the Mac Pro GPUs will be dedicated exclusively to driving displays, while the other handles all computational tasks. If you plan to run Windows on your new Mac Pro, for whatever reason, then you're in luck! In general, however, effective load balancing won't be seen until software written specifically to take advantage of the dual GPU architecture gets released, or until an OS-wide, general-purpose solution is developed.
In the meantime, parallel processing tasks will be sent exclusively to one card while the other sits basically idle.

Does this mean that dual GPUs are a gimmick? No, but as with any new hardware innovation, it will take some time for software developers to catch up. On the bright side, video applications will probably be among the first to add support, since they stand the most to gain. This provides enough bandwidth for just about any external RAID array on the market. And let's face it, if you need more hard drive bandwidth, then you probably shouldn't be using direct attached storage in the first place—a dedicated media server would be more appropriate.
By picking up a Thunderbolt Chassis, such as the Sonnet Echo series, you can install most PCIe hardware in an external enclosure with its own power supply and use it just like it was installed internally.

Many PCIe cards offer drivers for Thunderbolt support. Those that don't can often still be used by slightly altering some text in the relevant kernel extension's. To avoid an unexpected reboot, you'll need to ensure that the Thunderbolt enclosure is powered on before booting up the Mac Pro and that you don't turn it off while the computer is running.
I said before that the Mac Pro has six Thunderbolt ports.
Well, there's a slight catch. And the Mac Pro appears ready. Apple officially claims the computer can support up to three 4K displays. In fact, considering a single consumer Radeon card can drive a 16K x 16K video wall through one DisplayPort 1. But once again, the Mac Pro has gotten ahead of itself.
If you just want to hook up a 4K TV to the HDMI port or a Thunderbolt port using an adapter and push out video at 24 to 30 frames per second, you're in good shape. MST is a feature of the DisplayPort 1. As a workaround to get 4K60 right now, you have to send two of these streams at half 4K resolution x to a single 4K computer monitor. Unfortunately, at the moment, only a handful monitors know how to deal with MST streams in this configuration.
Let's face it: A lot can be accomplished on mid-range consumer desktops or even laptops these days. The system offers as much power as you can get without building a machine yourself.

And it fits in even among the most modern, stylish decor. If you are planning on editing multiple streams of 4K RAW, if you are doing advanced color correction, or if you're creating 3D animation, you're probably a candidate for a Mac Pro. If you're editing a wedding or corporate videos shot in AVCHD and doing minimal color correction, then to say the Mac Pro is overkill is probably an understatement—most likely an iMac will serve your needs just fine.
If you find yourself spending a lot of time waiting for things to render, or if you've thrown on so many effects in the time lime the footage is unplayable, the dual GPUs and 12 cores might be just what you need. At the same time, it is important to remember that simply throwing more power at the problem won't always solve the problem. If you're still editing on Final Cut 7, for example, then all of the processing cores and RAM in the world isn't going to make the program run any faster. FCP7 was written to run on ditch water because that was exactly what you needed back in the day.
But today it simply can't take advantage of a more powerful machine. Once it has consumed 1. Regardless of what kind of video you are editing or grading, what really determines whether the Mac Pro is worthwhile is the software you plan to use. In general, software that we can expect to be able to exploit what the Mac Pro has to offer will be the latest, most top of the line, applications like Blackmagic Design DaVinci Resolve or AutoDesk Softimage. Authors of these kinds of programs expect you to be using high-performance workstations, because the workflow they entail requires it, and will develop their product accordingly.
Provide connectivity for high-speed storage solutions such as RAIDs, capture cards, and displays. Thunderbolt also supports daisy-chaining of up to six devices.
