Drivers for Radeon R9 M370X?

Does anyone know where I can find the drivers for the Radeon R9 M370X, for Windows 8.a?

I have the new (mid-2015) MacBook Pro 15" with the Radeon card. I'd like to add an external display, but the drivers that installed with Boot Camp don't have the native resolution for it (3440 x 1440). The monitor manual recommended getting the proper driver for the graphics card.

I tried to find it on AMD's website, but no luck there. Can anyone help?

Thanks,

Mike

MacBook Pro with Retina display, OS X Yosemite (10.10.3)

Well I found the drivers on the Flash Drive I used to install Boot Camp in the first place, but that just gets me back to where I started.

Is there anyway I can take advantage of the external monitor's 3440 x 1440 native resolution?

OS X recognizes the monitor when I plug it in, but it does not automatically switch to the native resolution. TBH, I couldn't figure out what I need to do to change the resolution, but I haven't spent much time with it. Will try again when I get home from work later.

In System Preferences -> Displays, if you Alt/Option click on Scaled button, you should see the list of available resolutions.

OK, so I am able to get 3440x1440 resolution on the OS X side.

I still haven't figured out how to get it on the Windows side though.

Check Device Manager -> Display Adapter -> Properties and look for available resolutions. It may be a limitation of the BC driver which is installed.

I don't see anything about available resolutions in that area.

Can you look for a screen similar to the following? Click on Advanced Settings on the Screen Resolutions settings.

Ok, never mind, I have it working now. One thing is that you have to make sure you're projecting only onto the external display (and not the built-in display). I tried a couple different things, so I'm not 100% sure that's what did the trick, but it's working now in any event.

Thanks for you help though, I greatly appreciate it.
