OS X :: Dual Display And USB To DVI With Snow Leopard
Aug 29, 2009
I got a 24" iMac (2.93 GHz Core 2 Duo variety) about 6 weeks ago and hooked up my Matrox DualHead2Go to find it wouldn't push the two external monitors to their 2x1680x1050 potential. Ok fine, I got an Arkview USB2 to DVI adapter and had one monitor attached to the inferior DVI port, the second connected to the Arkview adapter and both worked at 1680x1050. Today I updated the box to Snow Leopard to find that neither solution works any longer.
The Arkview adapter simply disappeared. The computer refuses to see it and the console seems to indicate that it tries to talk to the adapter but gets nothing back. My guess is something changed in the way SL talks to drivers which trashed that solution. Then I tried the Matrox again thinking 2880x900 is still better than 1680x1050 and while it sees the Matrox box and sees it as 2880x900, the second monitor never "lights up". Does anyone know of anything that actually works with SL that will let me attach the two external monitors?

I have two Macs that run Snow Leopard. Lion looks to be quite different and offer great new features, particularly the app store. So, can a Mac become dual boot like a Linux can? I mean, may I co-install Lion side by side with Snow leopard rather than overwrite it? I have successfully done this operation on a Linux Ubuntu netbook with two different versions of Ubuntu, and a Windows 7/Ubuntu netbook. But I've never tried this on a Mac. Does a Mac OSX install allow options for how the user will install the new OS?

I just ordered a new iMac and I'll be upgrading from a 1GHz TiBook with Tiger on it. I have some important music software that I'm not 100% sure will work with Snow Leopard, but my understanding is that it's already ok for Universal Binary. So I had the thought that maybe I could put Tiger on the iMac and dual boot. I've never dealt with a dual-boot system before, other than a couple times when I played around with Classic Mode when I still had Jaguar and/or Panther.

I have an Intel Macbook with 10.4.11 running, and I wanted to upgrade to Snow Leopard. I've heard that the $29 upgrade disc will work with 10.4, and I have a couple questions.
1. I lost the original 10.4 install disc that came with my computer - would that be a problem?
2. I'm in a college CS program, and I'd like to be able to dual boot Windows onto the laptop. I think in order to do that, I have to do a clean install of OS X after installing Windows - can I do that with the upgrade disc?

The past few months I've made threads asking about eSata express cards and external storage and have received useful information. However, I've always neglected to ask this obvious and direct question. I've been recommended a few cards, one from OWC always comes up. But I never bothered to ask about "dual" versions because I thought I'd be able to find it on my own.
After weeks of casually looking around I wasted a few hours yesterday hard core searching online. I really need a storage solution for my exploding cache of photos and video that's been stockpiling and needs editing.
Perhaps FW800 or another interface could be a better solutions. But when I choose my new MBP 17" a few months ago I specifically kept the fact it retained the express card slot in mind because of it's higher transfer rates.
I'd get 1 TB but I'm thinking realistically I need 2+ TB of storage... and also I think I need to finally get my rear in gear about redundancy. I use Time Machine with an external FW400 HDD and back up my music separately there too but want to keep in mind future space should have redundancy in mind.

I have a question about using dual displays with my new macbook. The basic issue is this:
1: plug in second display and setup dual monitor support to use the external hi-res display and the macbook's display (no problem here).
2: drag windows to the external display and resize to use (no problems here either).
3. Power down and disconnect the external display.
4. Start up the macbook without the external display and try and open up a program that I was using previously on the external display. The problem is that it is resized and positioned for the external display and is now off the screen of my macbook display and I can't directly get to the title bar to move it or the resize corner to resize it.

I'm thinking about getting a Mini to use as an HTPC with a 42" Sharp Aquos LCD TV. if I connect the two using DVI to HDMI, will Snow Leopard detect that it's an HDTV and allow me to use the new 1080p setting without having to use SwitchRes X or DisplayConfigX? The 1080p setting works on my MBP when in extended desktop mode, but not in mirroring mode (because resolution is limited to the 1440x900 of my screen). I'm hoping that since the Mini has no display, 1080p setting will work out of the box. If someone could confirm that would be great.

Is there a way through a third-party app that I can have display presets? I have three 17" Apple Displays and a 52" Sharp LCD. When I'm sitting at my desk I'd like to have my monitors setup one way but when I'm sitting in front of the 52" LCD I'd like things to be setup different. For instance, when at my desk, the middle monitor of the three Apple displays get my dock and Apple bar. I have spaces enabled and certain apps reside on certain monitors and spaces.
When I move in front of the 52" LCD, I'd like to kick in a preset that moves things around without having to manually do it each time in the System Settings. One idea I had was to create another user. Not bad on the surface but it's kind of hassle not having the same routing to my other user's documents folder. Plus my software starts getting wonky.

I'll bring up 2 application screens for comparing some data. I move them arround a bit to line up data. After a few such moves - one screen suddently vanishs (to the right or left). I bring it back by reinstating the application - but then the other screen disappears. So now I can't get the 2 screens to stay on the display at the same time. I don't know exactly what triggers the first disappearance

My screensaver comes on like it should, or comes on from hot corner, but won't stay on. I've tried a number of things including:
-Trashing the prefs file (Library>ByHost>com.apple.screensaver.....plist)
-Starting from they DVD and fixing permissions and verifying/repairing the startup volume,
-Quitting all applications (I thought it was Time Machine or Chrome, but no)
-Making sure "wake for ethernet" is off.
-Disabling Bluetooth.
It'll stay on for a minute or less, and then stay off. So I'll come back and my display will be on. It also wakes up if I set the display to go to sleep.

Alright first of all, Hello to you all, I've been reading this forum for a couple of month even though this is my first intervention and i need a tip. Alright my situation is the following: I have:
-Macbook Pro Unibody
-Macbook C2D
-Snow leopard Disc x2
-Snow leopard image I cloned to a hard drive partition.
The situation is I have bought two licenses for Snow leopard because i have two macs. The macbook pro is the computer i use everyday and is fully functional. The macbook however took a big drop about a year ago and the display was totally broke along with the DVD and the hard drive. I retrieved an old HDD i had with leopard installed and put it in the macbook along with an external display and i now use this computer as a media center. The problem is i want to install snow leopard on it. The DVD drive is broken hence the reason i made a disc image and i wanted to install from the disc image. SO i restart the macbook with the alt key and as expected, the image from the usb drive is detected and i launch the install. The problem comes from the fact that when the installation starts, the external display is set as secondary display and i cant control the installation which is displayed wont eh broken display. Is there a way to remotely install SL or to set the external display as only display at boot through holding a bunch of keys?

Okay, so I installed Snow Leopard on my parent's Mac mini and it has a Hanns.g display connected to it. In 10.5 Leopard, the colors looked normal (still not as good as an Apple monitor, but colors were close enough). Anyway, like I said, I upgraded to Snow Leopard and now the monitor's color is all out of whack. I tried re-calibrating it and everything. The weird thing is, I got the Finder to look okay, but all of the blue icons in the Dock (iTunes, iChat, Safari, QuickTime etc) look PURPLE! Also, the menu bar selections are the same purple color instead of that light blue. The other weird thing is... looking at the Finder icon in the Dock looks half purple and half light blue, but when I hit cmd-tab, it looks half blue and half light blue. The cmd-tab icon of the Finder looks like I'd expect it to look, but all the colors are completely destroyed in the Dock. Another thing is... scroll bars seem to look like normal blue too. One more thing... when I tried doing the manual calibration, it shows you how bright to make the monitor with the little graphic. The graphic looked so washed out that I couldn't make the monitor dark enough (on the darkest setting) to get even close to the picture that the calibration tool wants me to see. Is Snow Leopard only compatible with Apple monitors? I installed Snow Leopard on my Mac Pro (Apple Cinema Display) and all the colors are consistent. The colors look the same regardless of 2.2 gamma or 1.8 gamma, so please don't bring that up. I want BLUE icons... not purple!

I have an original MacBook (1,1) that I use without the lid (the display was destroyed, and replacement was too dear, so I took the top off altogether). It's actually a pretty handy desktop. One problem is that sometimes windows go astray because the "Displays" setting is set for two screens (mirroring does'nt work because it reduces the resolution to 800x600). I am wondering if there is anyway to trick the macbook into thinking the lid is closed, and/or disabling the internal display altogether (basically so that only the external monitor is recognized).

After installing Lepord 10.7.4 I have lost the Display resolution except for 1920 x 1200 and 960 x 600. Neither of these is acceptable for my iMac. Before downloading 10.7.4 I had all kinds of resolutions shown in System Preference Display. How can I can I get back to them?

Before I had a 9c84 panel, went to System Preferences> Displays> Color> OPen Profile. Before (This was when I was running Leopard) I went down to 13 and found the panel type.
Now I get 'aagg' 'para' 32 parametric tone response curve on that line. Underneath in the description device manufacturer and device model are blank.

My Macbook pro's display has started playing up. Having green flickering lines which come and go randomly, especially on images with a lot of black. Right now, the lines just disappeared as soon as I connected to mains, to start recharging the laptop. I'm using OS X 10.7.4 with NVIDIA GeForce 9400M.

Got my iMac today, working great, but need help on how to hook up a TV to my system. Because my iMac is hooked up to the ACD 24" display, so the extra mini dvi port is occupied by the ACD, so then how do I hook up my 37" LCD TV to the iMac, so I essentially have three monitors hooked up to my iMac.
The ACD plugs into the iMac no problems of course, but my TV will be a different story, it's has two HDMI ports, S video and the 3 rca inputs.
Is there a splitter or something I can buy so I can add the TV to the set up. I've seen photo's here on this forum with 3 even 4 monitors hooked up, but I have no idea how to do it, searched here for a while as well.
Does anyone know exactly what adapters I need to buy to get the TV hooked into my dual monitor system?
