I think Apple has to come out with its own 4K monitor, hopefully alongside the updated Mac Pro.
Apple previously wasn't in the reference monitor business. They don't have to start now. A huge chunk of the 4K market is folks doing 4K movie editing. In essence, they need TVs, not computer monitors, for that.
Why else would they have introduced Thunderbolt 2 (also on the new rMBPs)
Same reason as use E5 v2 as oppose E5 v1 . Or 1866GHz RAM instead of 1333GHz RAM , etc. etc.
Thunderbolt 2 can deliver better result if interested in not exactly even PCIe data versus DisplayPort data transfer workloads. If not interested in 4K video traffic then disk I/O througput can go up. Given Apple has chucked
all bulk data outside of the Mac Pro that actually might be a good thing to work on. Ditto with the, no HDD in sight, MBP line up. ( yeah the MBP 13" is technically still around but wouldn't know that from the Apple keynote. )
and touted its "ability to run three 4K displays simultaneously?"
Here is the problem. Thunderbolt is not necessary for 4K display. HDMI 1.4 runs 4K just fine for movie like frame rates ( 'Hobbit' 48 FPS aside).
DisplayPort v1.2 runs 4K just fine.
Thunderbolt is not necessary to have a viable 4K monitor.
Nobody else is going to make a monitor with TB2
That says something bad about Thunderbolt in general.... not necessary something good about why add it to a Mac Pro.
Two of the 4K monitors hooked to the Mac Pro can easily be DisplayPort (DP) v1.2 monitors and they will work just fine. Thunderbolt's "pass through" mode is in play but TB isn't the big winner here unless it is critical that you add Ethernet/FW/etc ports to your 4K monitor. Frankly I doubt that makes the 10 ten feature list of the vast majority of 4K users right now.
and there are 6 damn ports on the back of the new Mac Pro!
Which is exactly why you can devote two of those to backwards DP v1.2 mode and suffer little TB connectivity constraints. Bucketloads of TB ports means there is
LESS demand for a TB docking station monitor.
I could be completely wrong but I feel Apple would be shooting itself it the foot if they didn't introduce a new display before 2014...
The prices for high refresh rate, 4K monitors remains very high. The prices will fall dramatically in 12-18 months. If Apple jumps in then with a solid offering then no problems.
When 4K display become affordable at 27" and/or 21.5" sizes then Apple will jump in when can deploy them on the iMac too. 4K in 2014 with an Apple label probably will be an Apple TV. I'm sure there will be some folks who will hook one of those to a Mac Pro.
Yelling "4K , 4K , 4K " is like spec porn star for the video industry right now. It just means you are aligned with the industry hype machine.
Here in 2013, any decent graphics card with proper DP v1.2 support can do 4K. Mac Pro doing 4K just means it is isn't years behind on tech.
