I think that Apple states that Windows may be installed on the Retina 5K, but will there be a problem with drivers?
More importantly, will Windows drivers be in conflict with Apple's proprietary Timing Controller they've announced for this computer?
I received a 5k retina iMac today and immediately setup Windows 8.1 using the built in Bootcamp process. NO snags installing, NO driver/exclamation marks, NO lockups. Audio, Bluetooth (kb/mouse) and Network (wired/wireless) works in Win 8.1.
BOTH operating systems have the same HUGE (for me!) issue. **No 5k resolution option, so I cannot maximize the real estate**
OSX:
Windows: Allows for a native resolution setting of 4k 3840x2160.
Updating the ATI catalyst software pack from the version shipped to the latest October beta had no effect.
You're right about Safari displaying high resolution images at 200% when you point the browser directly at them. I agree that is very silly. It's just another example of the ongoing nature of HiDPI support.
The thing is, running at native resolution, without enlarged UI elements is not exactly a great option either. I can't speak for the Retina iMac (yet), but on the 15" MacBook Pro at least the menus and especially buttons are just too small to use comfortably. Sure, it's far from unusable, but it's not very efficient. I don't view the doubled UI elements as a waste of pixels.
Where I strongly believe HiDPI is the way to go is with graphics applications. I use Lightroom, Photoshop, Illustrator and InDesign a lot, and all of these are great in "Best for Display" mode. They only pixel double the UI, leaving the work area and anything in it at full native resolution. This is what all HiDPI experiences should be like — and hopefully will be some day.
Y2kpc, I think it was predictable that Windows 10 is maxing out at 4K. Even though this OS supports resolutions up to "8K," it's still constrained by hardware &, very importantly, video drivers. The one thing that's seems not subject to debate is the fact that there are no AMD or nVidia Windows drivers capable of resolutions beyond 4K. Just as surely as you can't get 5K on a 4K monitor, you can't get 5K with any currently-available Windows video driver.
Now, it's my guess that Parallels Desktop uses the Mac video driver for Windows. (I've asked the question, but haven't gotten a definitive answer.). One can run a Boot Camp installation of Windows from Parallels. Therefore, if you have Parallels, it would be interesting to see what resolution you might achieve in Windows 10 when you run it from within OS X rather than booting into it.
Unfortunately I do not have immediate access to parallels and I had to hand off the new Retina iMac to the final end user for their desktop publishing work.
I agree that it's likely a driver issue at this point. What perplexes me a bit is that in Win8.1/Win10 beta, device manager/displays shows "Standard VGA" and uses a Microsoft built-in driver dated 2006. On my PCs, device manager generally lists a mfr & model specific item.
ATI Catalyst does report that the internal display is an iMac, but it states the panel itself is only capable of 3840x2160. Did Apple hard code something in some sort of machine hardware identifier for the boot camp process? ATI built both drivers (Yosemete and the latest Winodws beta). Is the limiting factor the driver or is it the hardware specs that Apple is passing to Bootcamp?
I will keep following this topic, as I'm sure eventually there will be a tested method for Windows at 5120x2880 (preferably using Bootcamp). When Dell ships their 5k panel later this year I am sure that will force the issue of Windows support.
Hallo,
just found this interesting article about running Bootcamp on an iMac Retina:
http://arstechnica.com/apple/2014/10/the-retina-imac-and-its-5k-display-as-a-gam ing-machine/
Especially this part is interesting:
The first thing I noticed upon booting up in Windows 8.1 is that Windows does not run at the display’s native 5120x2880 resolution. When I logged on, I was greeted by a desktop running at 3840x2160, one of a number of different resolutions commonly lumped under the "4k" banner (this particular 4K flavor is usually referred to as "Ultra HD").
Interestingly, the non-native resolution didn’t exhibit any visible scaling artifacts. The high pixel density seems to more than make up for the loss of resolution from "5K," and the display blends the 8,294,400 points yielded by 3840x2160 into the native 14,745,600 pixels quite smartly. Even sitting with my nose an inch or so away from the screen—a distance my mother assured me when I was younger would ruin my eyes—I couldn’t see any feathering or blurring around edges and lines. Type remained sharp, and everything looked crisp.
Overall Bootcamp seems to run very nice and snappy, even for gaming.
Although it does not do 5k yet, that will be ok for me.

I received my 5K with M295X GPU and SSD (1 TB). It works great, also in Boot Camp. It's true that the resolution is "limited" to 3840, but that's also the case with OS X (maximum 3200x1800) unless you use the above specified utility. In OS X, I actually set it at 2880x1620, as higher is too straining for the eyes (and boy, do I love huge resolutions, but it's just too much). It really doesn't matter too much, as the screen is glorious and no pixels are visible, even in 3840. I updated the AMD drivers to the latest version and beta, but that doesn't make a difference. If any of you want screenshots or tests to be run, let me know. Boot Camp works fine with Windows 8.1 and also with Windows 10 (which I am currently using) without any unrecognized devices.
Next step is to remove Boot Camp and run Windows 10 in full UEFI mode.
Hey ipodtouch245 hope u see this
is there any way you can help confirm if by having windows on Mac, it can run Cisco products? or a PC test that is .msi?
im planning on getting a Mac but not sure if this Cisco thing works on boot camp, anD It's for work
link is this
but I'm wondering Cisco software can be installed using bootcamp?
I took delivery on my 5K today. I have SwitchResX, but I don't think I'll be using it much. This display, at default, is true retina. My naked eye cannot discern a pixel from the viewing distance that Apple presumed would be commonly used OR from as close as I can get my spectacle-assisted eyes to focus on the screen -- about 4 inches. Running dual monitors, I certainly have no more need for extra screen real estate.
One interesting quirk did occur. When I opened Parallels, it DID open in a window less than 1/4 the screen size. When I dragged the corner to resize to nearly fill the display, it adapted in two stages. It first changed to very large text and window elements, then in couple of seconds reverted to text and window element sized just like the native OS X apps and other third -party apps I had open. I'm sure this is a Retina phenomenon, not a 5K thing, but I'd never seen that happen on my MBP Retina. It's working well.
Lastly, Extreme Tech issued their second amendment to their original article on the 5K, apologizing for the fact that they erroneously called the display's refresh rate "30 ㎐," and, more interestingly, explaining that the function for Apple's proprietary Timing Controller is to drive the display at 5K and 60 ㎐. Tim Cook was very clear about this device when Apple announced the iMac Retina -- showed a photo of it and everything -- but the tech world spent weeks pondering how Apple got this resolution and refrest rate from Display Port 1.2. Apparently, they aren't using DP at all. At least that's what the Extreme Tech guys are indicating.
I knew about hitting Option after the Display Preferences were up; that unhides the "Detect Display" button. But you're saying to hold down the Option key while clicking "Display" in the System Preferences menu. Way cool. Thanks.
However, there is a reason for using SetResX and SwitchResX in lieu of that method. They simply give a much handier interface for those who need frequent resolution switching. They are simple drop-down menus always resident in the Menu Bar.
y2kpc Do you mind sharing how you managed to install AMD's beta drivers onto your windows 8.1 system? I've tried several times to install both AMD beta drivers as well as the latest update drivers 14.201.1008 for my R9 M295X on my iMac but it still showing my current drivers as 14.200.1002.1002.
I've tried using the boot camp assistant tool to create an updated USB with drivers, I've also tried downloading software from the AMD website and doing a device manager update in windows 8.1 but it fails during installation and I receive an error message after I've selected the "Have Disk" option and located the correct M295X drivers. I also tried using AMD CCC software update and although the installation is successful the new drivers aren't reflected against my GPU.

I also noticed that your CCC is showing your graphics chipset as having a R9 200 series and not a R9 M290/R9 M295X?
AMD released a new driver that supports 5K monitors.
This is discussed in the following article:
http://www.tomshardware.com/news/amd-catalyst-omega-radeon-driver,28155.html
Can you confirm that this new driver give native 5K resolution in Windows 8.1
@fredz85 - I have encountered the exact same thing. Spent about 30 minutes in apple chat with a tech support representative and he referred me to AMD. I posted the question to them and got the following notation from the Catalyst Omega Driver documentation - "This driver is not intended for use on AMD products running in Apple Boot Camp platforms. Users of these platforms should contact their manufacturer for driver support."
I pointed out to them that AMD is the manufacturer of the graphics in these machines and that on their website there is a mechanism to support AMD graphics in Bootcamp. For instance, in the AMD drivers and download center you can manually select your driver by going under MAC Graphics you can select Apple Bootcamp. But this only contains the older Catalyst drivers.
I was hoping that this just means that the Catalyst Omega driver is still under development and that providing some reassurance of ongoing efforts and a timeline would have been nice but I only got a cold reply that the release NOTES stipulate no support for the Bootcamp environment.
Anyone else have luck in figuring out what is happening? Right about now I feel in between Apple and AMD both saying its in the other's wheelhouse.
Not happy with the support of either company at the moment.
@TrocidaNDH - I am with you on this, but I think it's a lost cause. Apple uses non-stock AMD cards and has never said that it would support 5K natively on Windows. Moreover, the current drivers work fine for me, the resolution is already huge and without scaling it's unmanageable. I know pure 5K would be great, but I don't think it'll happen soon.
Very curious about solution to driver issue, as I have 27" iMac Retina 5K with 4.0 GHz processor and maxed out at 32 GB RAM (purchased after market from Crucial due to hi Apple pricing), and the R295X card. Great thread ongoing here and hoping more information or support develops soon.
Hi everyone,
I have the basic 5k iMac with the x290 GPU.
I can install Windows 8.1 fine with Boot Camp, everything works, except the GPU which gives a code 43 error.
I have tried all available drivers and re-installing Windows. Is anyone else having this problem or found a solution?
David
There is no solution. The Apple support I spoke with told me to take the issue up with Microsoft. (really Apple?)
The community as a whole has yet to identify why some do and some don't have this problem. I've been trying to solve this problem since product release and have given up. I've tried Windows 8, 8.1 and 10. I've tried the Bootcamp drivers in every configuration I can think of. I've tried every version of the AMD drivers from their support page that has been released since February. I've reconfigured the .ini files in the driver package, and recompiled the driver package. Nothing works.
The next best solution is to use Parallels. (www.parallels.com) It required a bunch of hackery I wanted to avoid for my problem. It is an inelegant solution, but it's the only thing I can come up with. Also, if your application explicitly looks for specific 3D acceleration hardware it will fail, and this isn't the solution you want. Otherwise it benchmarks reasonably well in 3DMark and the like, and it's nifty to have Windows programs running along side all of my continuity stuff.
Boot Camp on iMac Retina 5K?
