Mac Pro :: Two Video Cards And Three Monitors - Application Freezes
Apr 1, 2009
Have a brand new 2009 MacPro with 2 video cards and 3 monitors. The following two things (so far) do not work:
Aperture, when secondary viewer is enabled.
Powerpoint, when I view a slideshow, which uses two screens by default.
Both work for a few seconds but then the application freezes, and in some cases I cannot force-quit my way out and have to hard reboot. Anyone out there with at least 3 monitors been have/have not had similar problems with two-screen full-screen applications?

The current setup already uses about 395W and this will increase with more monitors and video cards. Is there a way to turn off all but one (or two) ACD monitors (and the unused video cards) when not required? The latest Display page in OS-X 10.5.7 System Preferences has removed the option to turn off a monitor (and not the Mac Pro itself) via the side button. Tried turning off the power supply, but this is bad for the monitors, is impractical No rear-monitor USB2 or Firewire400 ports are used (for now).

I have a 2008 Mac Pro with a Nvidia GeForce 8800 GT in it. I'm currently running two Dell 24" monitors (at 1920x1080) and I'm looking to add two Dell 21" Monitors to the setup (at 1600x1050).
Do I need to purchase an identical GeForce 8800 GT or can I run a different card for the second paid of monitors?
I'm also planning on running Windows 7 via BootCamp with the same four monitors - are there any potential problems with this?
I'm also having trouble locating Mac specific graphics cards, are there any recommended retailers? Or will I be OK with a 'normal' PCIE graphics card? I'm in the UK btw.

I currently got the 5870 driving a 30" ACD and 23" ACD. Would there be any noticeable performance increase if I were get the gt120 to run the 23" and have 5870 run the 30" ACD (my work display)?

I have a Mac Pro and two video cards, and am upping the setup to a new Nehalem Mac Pro with the ATI 4780 card + NVidia GT120 card. For illustration purposes, I will use those two cards to frame my question, as we seem to be pretty familiar with their specs by now. My question is somewhat conceptual, and is difficult to explain, but I am counting on the MR collective intelligence to sort it out! I'll use a few scenarios to illustrate my point: Scenario 1: Heavy use of the 4870 card, using both outputs (two screens). Naturally, performance is better than using the GT120 card.
Scenario 2: Same heavy use, but this time one port from the 4870 is used, and one port from the GT120.
Scenario 3: Same heavy use, but both ports on the 4870 are used, and one port on the GT120 (three screens total)
Scenario 3: Same heavy use, but both ports on the GT120 are used, and one port on the 4870 (three screens total)
How do software applications deal with two video cards? Would running Aperture, FCP, gaming etc., degrade just one screen? Wouldn't the whole application have to slow down to accommodate the lesser card? Is there a "primary" card and a "secondary" card designation? I'm thinking of multiple monitor setups (three, for example) where a lesser card is necessary to drive the extra screen, but the application is using all three.

Is this any better? I know in 10.5 to switch between video cards (on the laptops that come with two) you had to log out and log back in. I've heard Windows can do it on the fly.

Apple only allows OSX to be used on Apple hardware. How is flashing a non Apple video card different to building a hackintosh?

Does anyone with a Mac Pro '08 and up run it with 2 high end cards? ATI 4870, 5870 and/or GTX 285 are the ones I'm thinking of.On my MP '09, I currently run a 20" off the GT 120 and the GTX 285 on a 24". I have another 24" coming in (the Apple LED), so it requires me to use the GT 120. For gaming purposes, I'm considering getting a 2nd high end card for the new 24" instead of letting the old 20" act as a slave on the GTX 285 (trying to minimize load on the gtx285, again for gaming).

I just got a third monitor and need another video card for my 08 MP. I really want to get the 3870 but here's the questions. How do two separate video cards work? Will the two monitors hooked up to the 3870 look good while the lone display on the 2600 look like crap? My background is mainly final cut pro, with a sprinkle of Color (with MXO and yes i know only one card will work) and motion. So should I just save my pennies and get the 2600? Will a 1080p panel and a 1680*1050 be too taxing on it

So what are the top AGP video cards? Either being a Mac or PC that I could flash with a Mac Rom. What are the better choices that I have? I used to use flashed PC cards of 9800 Pro for my G4s but figured there are better cards for the G5. I do prefer to get PC cards since they are cheaper and I can flash them.

Can the new mini's with the new video cards run final cut pro? I am not a video editor but do some small projects once in awhile. I would max out the mini at 4GB of ram running (2) 24" monitors.

I understand that the PCI-X slots are backwards compatible with PCI, correct? If so, can we install 2 additional PCI video cards? Or, can we use PCI-X video cards for Windows and somehow flash them with Mac drivers? Of course, there is the matter of budget: we have very little to work with. Would any of you have a spare video card that would work in this machine and be willing to donate it? I can email you an in-kind donation form you can use for tax purposes.

As stated, specifically I want to run Sim City 4 on my Mac Book Pro
2.66 intel i7
8gb ram
NVIDIA GeForce GT 330M 512mb
OSx 10.6.4
I checked the Aspyr Game Agent and it tells me it only supports
GeForce2 MX
Radeon 7500
The game will run but its glitchy, and slow, and occasionally freezes. So I know there are for PC but I cant any for the mac.

Right now I've got a dual-DVI PCI-X card that runs two LCD screens on my PowerMac (the 256MB variant that shipped with the 2.0 DC). However, I just recently purchased a 37" LG LCD to replace my aging tube TV and I'd like to output my Mac to the LG to watch movies, etc. And at the moment, I have to unplug one of my smaller LCD's and run a cable to the LG.

I am about to purchase a Mac Pro, and I saw the rumor about the new ATI Radeon 3870 coming for the Mac Pro in late May.
I had a few questions about it and Mac Pro graphics cards in general. First, will this card be available as an optional upgrade when configuring a Mac Pro from the Apple Store? Is that usually how it goes?
Secondly, I'm a video editor planning to use this Mac Pro primarily for Final Cut Studio and After Effects. It seems to have been indicated that ATI cards are better for this sort of work, versus the 8800GT they off right now.
Do these programs gain significant benefit from using ATI or is it more unsubstantial?
The other question I have is whether or not these cards would be recommended for use with the Avid product line (namely Avid Xpress Pro or Media Composer). It seems that Avid only will certify NVidia graphics cards, as it has with the 8800GT. I also am aware that Avid is not compatible with Leopard just yet, but will be in the near future.
So does anyone know if Avid performs well (or at all) with the ATI cards? Would the overall performance increase of ATI over NVidia be enough to take a chance with compatability issues?

I have a Mac pro 1,1 model and recently upgraded the video card to a Saphirre 6870 card. It works great right out of the box on both Mac and pc side of my Mac pro. From my online research, this card seems to be the best card that works with my mac pro so far, however I plan on getting an even more powerful card to use exclusively on my windows partition for games. I want to get a 6970 card, but that one may not work on the Mac side, so I plan on using both cards (the 6970 for the pc side, and the 6870 for the Mac side). There are two ways that I think may be possible but I wouldn't know how. One, is there a switch device that allows me to switch between cards without having to disconnect and reconnect them every time ? And second possible way, is there a way to house the second video card externally with its own power supply? The issue if that the are not enough power connections for both cards, so is there a way to power one card externally?
Info:
Mac Pro Quad, Mac OS X (10.5.4)

I may have sold a PC user on buying a mac and she's interested in the MBP. I noticed that some models of the MPB have a "NVIDIA GeForce 9400M + 9600M GT with 512MB" while others have the "NVIDIA GeForce 9400M." Are either of these integrated graphics? And what is the advantage of the models with "NVIDIA GeForce 9400M + 9600M GT with 512MB?" That sounds to me like it has two video boards. Why would Apple do this? And is there a big difference in video processing power between the models with one video board and two?

For all of you who are looking to compare video cards here is a decent list:
http://www.tomshardware.com/reviews/...rd,2011-6.html
I think the 120 = 9500GT and the 130 = 9600GT. Please correct me if I am wrong as I am not positive about this.

If I launch an app to do some video editing, does the MBP automatically switch to the higher-end graphics card? Or do I have to manually switch from "better battery life" to "higher performance"?

It is time to replace the ATI Radeon X1900 XT 512 MB graphics card that came with this computer. I am wanting to upgrade to something that will allow me to play Diablo 3. Any suggestions from as to what I need to upgrade to? I understand that there are a lot of differences as to which card will work in which machine. I just don't know the difference

I will be a hardcore PC guy gone mac soon. I am getting a MAC pro in a few days.
On my PC I run a dell 30'' and a sony XBR3 at 1080P on an 8800gt. It works well.
The one thing that could ruin my mac switching plans is my TV giving me problems.
I will have an ATI and nvidia card on hand for the MAC pro.

Both cards in OSX are reported as they should be and show acceleration, etc.I've noticed that the couple of games I've tried on the OSX side don't work right (well don't display right anyway) plus more bothersome is the fact that in VMware Fusion (2.05) running XP with DirectX acceleration turned on for the virtual machine, *any* software that runs and tries to use DirectX makes Fusion throw an error about the virtual machine performing invalid operations. (the error is thrown on the OSX side, not in the XP virtual machine)

The title says it all. Once in a while I'll be using Safari and it will freeze. The little error dialog that pops up normally offers a "Reopen the Application" option, but in these cases, it only says "Close" or "Report." If I try to open any application after this, nothing happens.
Has anyone had this problem? So far the only solution - a temporary one - is to restart the computer.

The problem began when I was attempting to force quit an app that had frozen last night. The Force Quit box wouldn't pop up and I got the rainbow pinwheel within Firefox. After the Force Quit box still wouldn't appear, I was able to shut down other apps and even able to restart the computer. Upon restart, once I tried to click an app on the dock, i'd see the icon bounce once or twice then just completely freeze. I'm able to move around the cursor arrow, but can't click anything.
This morning, I was able to open the Terminal (it never popped up in the dock for some reason) and did the 'killall Dock' command. At this point, my system started running real slow and I couldn't seem to double click anything. I had to cmnd + click 'Open' to get to the Activity Monitor. That opened, but then it froze and gave me the window pinwheel. I tried to force quit it, but it wouldn't quit. I had to hold down the power button to turn it off. When I tried rebooting, I couldn't even get to the Terminal anymore since now it would pop up in the dock when I opened it.

Mac OS 10.4.11. iMac G5 and MacBook. Here is the sequence that leads to the freeze.
System Prefs > Dot Mac > Sync When I click on Sync or Advanced Sync (using my G5) the application freezes(surprisingly I am able to click on iDisk in that application before clicking on Sync or Advanced Sync and I'm taken to iDisk window (iDisk storage, etc.). After I click on the iDisk button if I then click on Sync or Advanced it (the application) will freeze. When I use my MacBook I have no problems i.e. none of the problems noted above for the G5.
Prior to September 15, 2010 I used dot Mac on both G5 and MacBook i.e. synch both of them with no problems. However, I renewed my dot Mac account on September 15, 2010 and that seems to be when my problems started.

I am a fairly new Mac user after using Windows PCs for many decades so please bear with me on this. I purchased a new unibody MacBook Pro a few months ago and everything works as advertised except for one thing. If I am looking at myself in photo booth the video is fine. However, if I open any other application---browser, iwork, iphoto, anything my picture on photo booth freezes. The picture unfreezes and returns to normal video as soon as I close the other application. I bought a MacBook Pro for my 14 year old last Summer and it has the same problem which leads me to believe there must be some tweak or some fairly obvious fix that I am overlooking. Because of this issue neither laptop can be used for video chat--just won't work.
I would appreciate any suggestions that anyone might be able to offer. Both MacBook Pros are fully updated and both are 15" screens. If I change user accounts the same problem occurs. I spoke with AppleCare and after trying a few things they said I would have to take the machine to an Apple Store but I am hoping to avoid this if possible. Spoke on the phone with one of the "geniuses" at the local Apple Store and he said he had never heard of this issue which seems strange since it occurs on both of our Macs---unlikely coincidence.

I've got an issue with iPhoto. Whenever I open it, a window opens asking if I want iPhoto to open every time I attach a digital camera, then the rest of iPhoto opens and the application freezes, and I am unable to click anything.
