Q: Can 2008 Mac Pro run 4K or HD screens with the right video card?

Hello guys,

 

I have been running my  2008 Mac Pro(2x2.8ghz Quad Core) for a while now with the basic ATI Radeon HD 2600 XT 256 MB card in it. I do a lot of photo editing on my computer and was thinking of upgrading the memory, installing a SSD drive and upgrading the video card to either support 4K or HD monitors.

 

I have found very little on the subject of 4K monitors and which video card could support it or HD for that matter.

 

Also wondering how I could run my computer to my 1080P HD TV and possibly put a blu ray drive in my tower as well.

 

If anyone could shine some light on this it would be appreciated.

 

Thanks.

MBP & MP, Mac OS X (10.5.6)

    For the Mac "Sapphire" version of Radeon 7950, there is a driver for download(probably intended mostly for pre 10.8.3 systems). I wonder if that driver could work for a non-mac Radeon 7950 card, either out of the box or with some editing of system files?

    Anyone tried 4K with Yosemite/10.10 yet?

     

    I guess it'd be interesting to know if there are any changes there in terms of drivers etc?

    If someone has, then they are not allowed to discuss it here or they'd be violating their NDA as well as the ToU of these forums.

    I guess I should just apologize, then, and wait for the official release of OS X 10.10.

    How did You force 60Hz for 3840x2160? Using SwitchRes X? I didn't get the option, so couldn't see the strange behavior.

     

    Hopefully there will be better drivers in 10.10!

     

    In Windows/BootCamp, installing Catalyst 12 from the cd that came with the card didn't give 4K, rather it gave a rather strange stretched resolution.

    Installing Catalyst 14 fixed that, and gave me full resolution @60Hz.

    I read most of what everyone said. But I do believe your model Mac Pro (same as mine) lacks an MDP (MiniDisplay Port). Apple sells an adapter that goes the other way (to DVI) but we already have Dual DVI and there don't seem to be adapters for DUAL DVI > MDP -- or are there?

     

    Most importantly, although newer OS versions may run 4K using certain video cards, that doesn't magically produce an MDP. So it would seem at this point that 4K won't work, unless one can install an MDP onto a 2008 Mac Pro (which doesn't have one natively). Any takers?

    I'm getting 4k at 60hz over DisplayPort from a GTX660 on 10.9.5, but doing anything with large text views is rubbish. Xcode is practically unusable. TextEdit full screen lags something awful. I'm not sure if the limitation is the GPU or the CPU, guess I'm going to have to try a faster GPU to see. GTX770/780 seem to work well for Windows users but I'm not sure if the Windows window server is as GPU-intense as the OSX window server..

    Dell 2715Q 4K HD Monitor

    ATI Radeon HD 5870 1024 MB Graphics Card

    MacOS 10.7.5 Lion

    MacPro 2008 3,1

    Apple 30" Cinema Display

     

    I am trying to install a new Dell P2715Q monitor to my existing system.  The Apple Cinema display (2006) is connected using the dual-link DVI output at 2560x1600 resolution.  This works beautifully.  Still.

     

    I am trying to connect the new Dell monitor into the mini DVI port on the graphics card to the DP port on the monitor and get the notification that there is no DP connection.  Why is it not connecting?

     

    In reading online I see that other users have done a conversion from the mini dvi to an HDMI connection on the monitor and I am wondering if this will work?

     

    The Radeon HD 5870 has the dual link DVI out put (I need this for the Apple CInema Display) and two mini dvi ports.  If I am reading the specs correctly, the maximum resolution on the mini dvi ports is 2560x1900.  If I use a converter to go from one of the remaining mini DVI ports to the HDMI input port on the monitor, will I get the 2560x1900 resolution, or will it decrease to 1920 x 1200?  And will the conversion to HDMI even work if the DP connection doesn't work?

    I'm also trying to determine if I need to do a system upgrade (I don't know if it's feasible).  I can only upgrade to Mountain Lion because of the limitations of other software that I have that runs very stably on Lion.  In other words, everything works well now and I really don't want to fix something that isn't broken.

    I am trying to connect the new Dell monitor into the mini DVI port on the graphics card

    That is a Mini DisplayPort. You can convert directly to [full sized] DisplayPort with a cheap (US$10) cable/adapter that has NO active components. On some displays, you need to change settings inside the display (typically with on-screen Menus) to support DisplayPort 1.2 for higher data rates.

     

    I recommend you stay away from HDMI if you want to go wider that 1920 by 1080p, or faster than 30Hz refresh.

     

    You CAN convert to Dual-Link DVI, but that adapter costs US$100.

    Thank you so much for the clarification on Mini Display Port.  All of the different names and abbreviations are very confusing.

     

    The cable that was supplied with the monitor goes from the mini display port on the computer to a DP (I'm assuming that means Display Port) port on the monitor.  This is what I've been trying to use and the monitor always gives the alert that "There is no signal coming from your computer."  So, if the computer and monitor won't communicate with this very direct cable, I'm wondering how an adaptor is going to improve the situation.

     

    I hear what you are saying about HDMI and I DO want a resolution at least equal to the Apple Cinema Display (2560x1600), so I will stay away from HDMI.

     

    If I turn the monitor on while my Apple Cinema Display is connected, the Dell monitor becomes the primary screen but is black and I lose control of mouse and keyboard - so I can't go into "Displays" in System Preferences.

     

    Is this an issue with Lion?  Is it the video card?  (If the video card supports my cinema display at 2560x1600, it seems like it would support another monitor at the same resolution.  It is supposed to support three monitors.)

     

    Thanks in advance for your help.

    Unlike Windows, The Mac uses one highly-parameterized Driver for every display. To set the settings, the Mac sends a query to the display at certain times. If the display does not answer (sometimes because it is not paying attention) the display will get no signal. Once the display has answered, its Name and capabilities will be shown in the system report:

     

    displaynames.png

     

    You must set the display to expect data on the DisplayPort so that it is ready when the query comes from the Mac. The query happens:

     

    • At Startup

    • at Mac-end cable insertion

    * at wake from sleep

    • at Option ( Detect Displays ) button in the Displays Control Panel [when working with another display]

    Okay, finally managed to get into Displays in System Preferences by parking the Displays window on the margin so I could grab it when I turned on the Dell monitor (enough of it was hanging into my apple monitor that I could grab it - then I could also move the control menu to my apple monitor so I could use the mouse, etc.).

     

    FINALLY got the Dell monitor to show something on the display but only if I set the resolution to 720 x 576(!).  As soon as I set the resolution higher, the screen goes black again.  It automatically selected the 50 Hertz setting - the other options in the drop down were grayed out.

     

    Have tried restarting with both monitors on, only the Dell on, and only the cinema display on.  Always the same black screen.

    With 10.9.2 there is now 4K at 60Hz support for 7950/70 cards via MDP.

     

    So they can output fully supported 4K to an Asus or Sharp PQ-321. (The one Apple sells now)

     

    I can't speak for Dell, LG, etc as I don't have one.

     

    MANY cards with DP or MDP can do 4K at 30Hz in 10.9. The GTX680 is still limited to 30Hz in 10.9.2.

     

    7950/70 and GTX680 can do 4K at 30Hz via HDMI in 10.9.

     

    Again, I can only speak for Asus/Sharp 32" 4K displays because that is what I have to test with.

     

    As far as making more pixels appear on an HD TV, it AIN'T GONNA HAPPEN. The Dual Link DVI ports on 2600XT are limited to 2560x1600 @ 60Hz. You may be able to use SwitchresX to slow refresh rate down to some absurd number and get to 4K but your mouse cursor will be skipping and jumping across the screen like a school girl.

     

    A 4K display has literally 4 @ HD displays worth of pixels. Yes, you can fit 4 HD images onto a 4K display without overlap or pixel scrunching.

     

    An HD display is 1920x1080. If your photos are larger than that, they won't fit without compressing pixels into a single pixel. Simple mathematic fact.

     

    Can you put 5 gallons of water in a 3 gallon bucket? Nope.

     

    So, can anyone recommend a reasonably priced ~27" monitor on which I can get 2560 x 1600 resolution through one of the available mini display ports on my ATI Radeon HD 5870 1024MB video card?  After hitting a dead end on this Dell, I've looked at multiple other monitors and the information on the others is as scant as it was on the Dell.

     

    I'm running Lion 10.7.5 on a MacPro 3,1 2008.
