Mac Pro :: Updating To 10.6.3 - Now Dual Monitors Don't Work?
Mar 29, 2010
I have a Mac Pro 1,1 with a flashed ATI Radeon HD 4870 XFX. Had no problems with it ever.
Installed Mac OS X 10.6.3 software update and now the second monitor says No Input detected. Switched second monitor to first monitor and it worked fine, but the second DVI port no longer works.
Need to get this figured ASAP as I have a lot of work to do today... very unhappy with this update. Anyone else having a similar issue or have any thoughts on what to try? I've done everything I can think of.
Do I need to flash it again? Seems silly to have to flash it every time you update the OS. The video card is still recognized in System Profiler. HD 4870 with 1GB GDDDR5 VRAM.

I need a bit of insight as to how to maximize the performance (and if there is any) with dual display setups on both my MP1,1 and 5,1.
First off, MP 5,1. Currently I'm running a 30" ACD off a DVI and 23" of a MDP to DVI on a 5870. The 30" is my main work display - the 23" is pretty much running trivial things, like browsers, finder, iTunes, etc. Since VRAM is being split between the two displays, would I benefit from installing a second video card to just run the 23" monitor and dedicate the 5870 to just run the 30" ACD? If yes, what should I use? I have an old 7300, but If there's anything better out there that's non cable powered, I'll get it. Also, there are times (rarely) when I need to run Windows 7-64bit to do some 3d CAD work - would having video cards from different vendors (hence different drivers) cause W7 to go nuts (conflicts, etc)? I can live with just the 30" on W7. I want to get get the most out of 5870 and 30" ACD while not running into conflicts under OS X by introducing another video card.
Second, MP 1,1.
It's windows 7 64-bit machine only. I have OS X installed, but since I use it for work I never boot into it. It's running a 27" display (1920x1200) on DVI and 23" (1680X1050) on MDP to DVI adapter. Again, the bigger display is my work area, and the smaller one runs browsers, outlook, etc. I do 3d CAD work, so more VRAM I dedicate to my main display, better it is. So back to my original question...what are my options? I do have that 7300 hanging around, but, again, I'm not so thrilled on mixing video card vendors and drivers. Should I just get some sort of low grade Windows based ATI Radeon card (don't care much of OS X on that machine).

I have an issue with my 4870 (Mac edition) that has been occurring since day one (when I purchased it last month), but it's not something that happens every single time.
I've run into a problem that the 4870 has trouble recognizing one or both monitors plugged in. If I shut off power to my displayport-connected main monitor, it'll throw the menu bar, all the desktop items, and application windows onto the second monitor (DVI-connected). This also happens when I shut off the second monitor (desktop items and app windows get shuffled to the main monitor).
The other issue is that on startup, it may just be slow to recognize one of them, and the above screen-swapping issues happen anyway, followed seconds later by the screen once again being recognized.

I have a new 2010 MBP and I'd like to hook up two external monitors to it, more specifically, two ASUS VW246H 24-Inch Widescreen LCD Monitors. Either via HDMI or DVI connections. I've found various usb monitor adapters, but i've read that many can't quite 'keep up' and I really can't seem to find a solid solution out there.
So does anyone have a dual monitor setup they currently use, if so, what are you using to connect the mini display port to both external monitors.

I recently purchased a second 22" Dell 2209WA to go with my Mac Pro. They are both running from the ATI Radeon 4870 on my Mac Pro (2009 Quad) but the Expose performance seems to be really quite poor. Displaying all the windows is very juddery and not smooth at all. Is that what I should be expecting now? I wouldn't have on a �2000 Machine. Going into Spaces is fine, it's just Expose thats poor.

I'm curious if anyone has tried out Spaces with Dual Monitors yet?I'm not sure if it will matter or not, would kind of be cool to be able to specify which space goes to which monitor.....I have a New iMac with extra 20" LCD and will be upgrading to Leopard tonight, so I guess I'll know then...just wondering what to expect.

So I was using my second monitor to run my G5 while transferring files to my new 3.2 octo, and then the past week I was using it to transfer my old PC files to my new PC. Now I finally just went to hook it up as my second monitor on my Mac Pro, and found out that I CAN'T FIT BOTH DVI CABLES TO THE PORTS!!!
They're too close together so I can fit one monitor into either port, but not both simultaneously. My monitors are the aluminum 23" ACD's w/ DVI.

I was wondering if in anyway possible on a mac I can make my two monitors at the moment act as one virtual monitor? Know what I mean? So I want like one extra wide resolution which would cover both screens, not a separate resolution for each. Hope this is possible, much be in some way.

Does anyone know how to get hot corners to work on dual displays? I had a monitor plugged into my MBP 2.5ghz and after changing the relative location of the monitor in display settings, left of main screen to top of main screen, the lower left corner would allow me to access Expose for the applications in the current monitor, instead of exposing all application windows on both screens. This feature is very helpful though I cannot repeat it. Is there a certain orientation of the monitors that will allow each screen to have it's own hot corners functioning for that screen of was this just a fluke?
it would be nice to be working on one screen and watching a movie on the other without the movie expose ing when I only want to expose the applications/windows on the monitor who's corner I accessed.

I have an intel imac and would like to set up a second monitor to allow for more simultaneous side-by-side space when I do programming/editing. As I'm not interested in paying $1000+ for an apple monitor, I'd like to use a third party one. Thus far, I think I need a VGA to MiniDVI adapter [url], but then can I use ANY monitor that has a VGA port? And then will it be as simple as plugging in the second monitor and detecting it? Will the iMac screen remain unchanged? Will the computer just "know" when I scroll across one screen to the other

I do not know much about this, so if i don't explain clearly, ask and i'll try again.
So basically, i have an iMac 21.5" Late 09 model here and a LOGIK TV next to it that has a channel for 'PC', i was wondering if it was possible to use them as 'dual monitors' for the iMac?

I have the setup in my sig and I'm running one Dell 24" at 1920x1200. The thing is that I'm considering getting another monitor exactly the same so I can run dual monitors, but I've read that some people have had some lock-up issues while attempting this. My question is who wide spread is this before I go and drop $600 on another monitor?

I am a web developer, and we are a Windows shop, but many of us are moving to Macs since we can run both OS X and Windows on the same machine. Well my work is purchasing a Macbook Pro for me, and I'll be hooking up an external monitor to it to replicate the dual monitor setup I have now.
As I learned in the OS X forum, I'm able to specify which programs I would like to launch in which "Space" upon boot. My question is, is VM Fusionware compatible with a dual monitor setup? As an example, could Space "1" contain my OS X desktop on both monitors, and then if I switch over to Space "2" which has VM Fusionware running with Windows, will the windows desktop span both screens as well?

I are disagreeing over the new MAC Mini and the two video cable connections on the back. He said it will support dual monitors and I said it is just a different type of connection for one monitor.

2. If so how would I go about this?
3. Will just any monitor work or has to be a certain type?

This has been going on since the beginning of time: You put 1 YouTube video in fullscreen (on screen #1). You click anywhere on screen #2 and screen #1 leaves fullscreen! Is there an app or script that will allow me (and the rest of the world) to watch 2 flash videos in full screen on 2 monitors? I even tried 1 video in Safari and one in FireFox but to no avail.

I have a macbook 2006 model with the mini-dvi connector. It has snow leopoard installed. I plugged in 1 external monitor and it displays 1680x1050 resolution on that monitor which is perfect. What can I expect if I split that DVI output with a DVI splitter to two monitors?

I was wondering if it was possible to utilize dual external monitors with the Macbook pro's. With my thinkpad and a port rep I can use dual monitors as long as I keep the lid closed on the laptop. Is this possible with the new macbook's that were released today?

I am looking to hook up two ~20" monitors to my macbook pro. My office is a PC environment, so I need to boot into PC mode (any advice as to the best software to use? VMWare?), log into my company's remote access, and then use a PC peripheral keyboard and mouse and work in excel and powerpoint.Any advice as to the following: 1) how I hook up the two monitors (i.e. what cables / extra peripherals i might need, any tips on dealing with remote access) 2) any recommendations on PC keyboard and mouse, any tips you might have there. 3) what the best low-cost monitors are.

One simple question, do exist the possibility to connect 2 DVI Monitors, both HD, to a MacBook Pro 15" in order to "extend" the screen? No need to keep the MacBook pro LCD on. What is needed to succeed?
