Windows won't display on external monitor on MBP

I've tried every combination of the Windows ATI control panel (w/BootCamp), but I can't get output on an external monitor (mirror or extended desktop). The computer thinks the desktop is extended, because I can move windows out of sight in that direction. The only time I see something on the other monitor is in OS X (works fine) OR during boot of Windows - I see the Windows XP boot screen.
Anyone have any success?

Since I heard other people had DVI
connections working, I tried that, and it worked.
Then, I plugged an analog monitor back into it, and
that worked too! Seems like it just needed a kick
(weird).
I too have tried all manner of combinations and restarts to get Windows XP output to SVGA data projector. I get picture during windows start up and then it disappears - never to return once XP has loaded.
What order do you use to link up all the bits? is there a way to toggle external monitor in XP via boot camp on a Macbook Pro?

I have a PowerBook G4 with a non-functioning monitor. It used to work with an external monitor, but I reinstalled the OS, which cleared the display preferences and now when I restart it won't detect the external monitor. How do I fix?

I have a PowerBook G4 with a non-functioning monitor. It used to work with an external monitor, but I reinstalled the OS, which cleared the display preferences and now when I restart it won't detect the external monitor. This means I can't use the computer anymore. How do I fix? I tried using the Command+F2 keyboard shortcut, but it doesnt' work. It's possible that since I reinstalled the OS, it still needs to be set up, so there's only a welcome screen (but since I can't see it I'm not sure).

There is no limit to the number of times you can re-install Office on the same computer.

New iMac won't recognize my external monitor.

I just upgraded my workplace computer to a late-2012 iMac (with the thin edges) from the previous older model.
I have an external monitor that I use as a secondary screen - a Samsung SyncMaster BX2440 - that worked great on my older machine using the DVI adapter.
When I plug the same adapter into my newer machine, it won't recongize the external monitor.
I tried resetting the PRAM, but no dice.
Is this a Thunderbolt issue, and if so, how easy is it to resolve? Do I just need to get a newer DVI adapter?

Loner: I looked at that and it only shows the main iMac display. Doesn't show the other device.
The model I'm using is a Thunderbolt machine (has the lightning bolt arrow icon). The previous machine was a DisplayPort model.
The adapter is the Apple-issued DVI adapter, but I'm guessing that even though TB and DP use the same physical plug interface, the adapters are not compatible?
(The adapter has the standard monitor icons on it - box with vertical lines on either side).

My mac won't recognize an external monitor. The screen Goes Blue Once, then goes blue again and the second monitor just turns off. I am using an HDMI adapter to a visio TV. I also have my xbox on the tv. Can anyone Help??

Lol, figured out the first part. Just for those who may be searching, when you click on the Display Preferences, and click on the arraingment tab... it not only shows where your two screens will be displayed, but the WHITE BAR at the top of one screen is the dock/toolbar. Click and hold to grab this and just slide it over to the screen you'd like it to be on.
You have to release it IN the screen box, not on top of it... and it should pop right over to the new (or old) screen. At any rate, you can put the dock on either (or any) screen that you prefer.
I am thinking of ordering more of these. Lol. 3 monitor setup seems like it would be crazy good.
Still looking for the answer to keeping the new 16" screen on the right without switching between screen #s with that... not expose... Lion feature.
Thanks. Hope my other question has an answer out here.

Got the "apple firewire ntsc" choice to show up even if grayed out and "missing" under "audio/visual" menus by recreating choices in Easy Setup under "final cut pro" MENU thank GOODNESS because I was reading horror stories on here about this under another thread with someone trashing preferences, reinstalling and the works and still not getting it to show up...on my search now for an analog/digital converter up at b&h...find it odd that the s video connector wouldn't show the crt monitor when I put both displays through the 3870...I switched it back to see if it worked again when only the one dell monitor display was there and there it is again mirroring the screen display on my desktop...just can't be seen as an "external monitor" in fcp...couldn't find anything specific in the shane ross threads to this. I'm sad the program doesn't just see the s video connection though the 3870 though my computer does fine and will query up at b&h in regard to what might be affordable as far as a digital/analog converter. It's also weird in itself that when I put the two dell monitors on the one card my computer no longer could see the s video crt connection...makes no sense. Will report in later as to what I discover up at b&h as I'm sure there's a world of people out there using this sony crt monitor still even into the upgrades with computers and software so I imagine therein lies the solution. Thanks again and I'll report in as to what hardware might be suggested for me.

MacBook will not display on external monitor in clamshell mode

System information:
13 in. MacBook (2.4Ghz Intel 2-Core)
10.6.7
External Display connected with Apple DisplayPort VGA adapter
Apple Wireless Keyboard
Generic wireless mouse that connects to a USB stick plugged into the MacBook
This is dirving me nuts because it was working perfectly until about 2 weeks ago. I was following the pocess outlined here. http://support.apple.com/kb/HT3131
Here is what happens now:
MacBook display and external monitor are in mirroring mode. All devices are powered on and plugged in.
Close MacBook lid. MacBook goes to sleep. Blinking LED.
Hit spacebar on the Apple Bluetooth keyboard. The LED changes to steady on. However, the external display never shows the desktop. I've tried Command-F1... nothing.
If I open the lid again... the MacBook goes back to sleep.
I then have to pull out the DisplayPort VGA adapter to wake the MacBook up again.

You could try resetting the SMC and see if that helps.

Some windows won't display?

For some reason, some of my windows in dreamweaver will not display correctly, or much at all. For instance, when you first open dreamweaver and select "new dreamweaver site" all I get is a window that displays a few text fields and then whatever is behind that window (almost like the entire window is transparent, except when I move the window, it doesn't change to match what is behind it) My system exceeds the dreamweaver minimum requirements.
I operate on windows xp
I am running the trial version.

I have, Thank you. I kinda sorta fixed the problem, I discovered that when I move the window off of the screen, it appears correctly, annoying but I dont know what else to do.
Thanks alot for replying

Can't sign in on external monitor with MBP after Yosemite upgrade

After Yosemite upgrade, when I turn on my MBP, I can't sign in using external monitor with MBP, always could before Yosemite. Blurred image of my wallpaper shows on monitor, can move arrow on external screen but sign-in only shows up on my computer screen, with no arrow. Since there is no arrow on the computer screen, and no sign in box on the external monitor, I have to unplug the external video to sign in on the computer, then plug in the monitor again. Any ideas?

NOWEK,
Thanks for this suggestion, but so far no joy. I have zapped the PRAM, jammed the Frabitz and smashed the Gafrogsnicker, all to no avail. When the MBP restarts I get a blurred image (extreme "vibrancy") on the external monitor, but no images of the login accounts to choose from or the other options. However, on the MBP screen I get all that. The keyboard and mouse respond, but just doesn't display on the external monitor. This is of interest to me because I have the MBP down in a credenza with other related gear and the external monitor and keyboard up on my desk. It's true I don't have to do this often, but still, it just started this aggravation with Yosemite. Thanks for trying to help.

MacBook Pro won't sleep with external monitor

Hello,
have a problem. I'm using external monitor with my MacBook Pro. If I close the lid, I see all windows on external monitor and Yosemite won't sleep. Can you help me please? My external monitor is Samsung 21.5" and I'm connecting it to MacBook Pro via DVI.
Thank you

Hey Renecek,
My first thought was, "Hey, you are using closed-clamshell mode".

If external monitor is placed above laptop screen, dock won't appear on external monitor

I've just migrated from PC to Mac and I've found something that drives me crazy. The dock won't appear on my external monitor if the external monitor is placed directly above the MacBook Air built in display. At home. I plug in my external monitor into my MacBook Air, place my laptop on my physical desktop just below my elevated external monitor. My MacBook Air is open and I use its keyboard and its display, but my main display is my external monitor. I configured displays to match the physical arrangement:
Darn: the DOCK REFUSES to appear on the "main screen"!! This drives me crazy -- this did not happen in Windows! The task bar obeyed my "main display" setting.
I can get the dock to appear on the main screen if I tell Mavericks of an arrangement that suits Mavericks -- somewhat side-by-side, as follows:
Now the dock shows up on my external monitor which I'd identified as my main screen before all these shenanigans.
The problem with the workaround is that the mouse does not track correctly between monitors so it's not an acceptable workaround.
Does anybody have any ideas on how to work around this for real?

Try booting your laptop normally, and then plug in the external monitor when the computer has fully logged in (or when it's waiting at the login screen). Does the problem still happen when you do that?

T530 - Dual boot not displayed on external monitor when docked

Hi,
I just got my new T530, loaded all my applications and data from my T61. The T530 is connected to the 4338 docking station.
I have Win 7 on the internal disk, and Win 8 on the ultrabay disk.
Dual boot works fine when undocked, but when docked and the lid is closed I don't see the dual boot selection on the external monitor and the PC boots into Win 7 (which is my default OS).
When cold or warm booting I also don't see the Thinkpad splash screen.
I did not have this problem with my T61 when docked. There the splash screen and dual boot selection was displayed and I was able to select which OS I want to boot into.
Any ideas whet I can do here?
Thanks

As I came across this it's a matter of the two graphic cards and how they are shared.
The Intel always drives the Laptop-Display and the analogue port, the digitalports at the docking are all driven by the Nvidia Card.
The splashscreen will always be displayed with the intel card and therefore not be visible with the digital ports at the docking.

Preferences window won't display along with other windows.

I am trying to edit my preferences. It only displays a little hint of a window with an X to close it. The same thing for reporting a bug. Basically I have not been able to get one popup application window to display.
I am on Vista Ultimate x64 with dual monitors running in 2650x1600 resolution.
Basically I can't even report the problem as a bug since that feature won't display the window either. Hopefully Apple is monitoring this board.

The same thing is happening to me in XP. I couldn't even log on to this site as a window (probably asking to save my password) is popping up but all it shows is a small title bar with an X. No preferences, can't report bugs or even customize the toolbar.

W520 won't boot to external monitor

Hello, I have a W520 with a 4338-30 docking station. I have an external monitor plugged into the DVI on the docking station and when the laptop is docked, it does not boot to the external monitor. I have to open the laptop to log in. Once the laptop is all the way booted into windows 7, I can then view the screen on the external monitor (albeit with a lower resolution). It worked fine when I had XP.
I did go into the BIOS to change it to the external port (DVI) however, only the Thinkpad LCD is available as an option. I did update the BIOS to 1.37 to see if that would fix it, but that did not work.
Anyone have any suggestion?
Solved!
Go to Solution.

I think you also need to turn Optimus off or there is another setting, can't recall specifically. You need to select the external device. Otherwise for what you have set seems correct it not showing the other display until you are nearly completely booted into Win 7. I am not using a dock and my external display is via the displayport connection and booting using an external display works least on my system.

Single Frame Displays on External Monitor

I have been searching online for the past three hours, trying to find a solution to this. I have found threads describing similar problems, however, I have done everything suggested in those threads, and nothing seems to work. I am at my wit's end.
The problem: When I attempt to play my sequence in my timeline, while connected to an external monitor, then audio plays, but only a single frame shows on the monitor. It updates to the most current frame whenever playback stops, but it only shows a static image. Meanwhile, the canvas window in Final Cut Pro displays nothing.
Things I Have Tried:
I have selected "All Frames" under View > External Video.
I have Refreshed A/V Devices.
I have made certain that the Canvas display size is small. Currently, it is at 50%, and I have also tried setting it to Fit To Window.
I have gone to Easy Setup, and selected NTSC, DV-NTSC.
I have checked "Mirror On Desktop" under Audio/Video Settings > A/V Devices > Playback Devices.
I have also tried unchecking "Mirror on Desktop."
I have set Video Playback to Apple Firewire NTSC (720 x 480).
I have set the Sequence Preset to DV NTSC 48 Khz.
I have set the Device Control Preset to Firewire NTSC.
I have exited Final Cut Pro, made sure the deck was on first, then turned on Final Cut Pro.
I have restarted the computer.
Further Notes: I've noticed that the problem might have something to do with how sequences are displayed. If I double-click on one of my video files in the Final Cut Browser, and open it in the Viewer window, it plays fine, even displays fine in the external monitor (my deck). Furthermore, if I open different Final Cut Projects that worked fine previously, they now have the same issue. So I would assume it is not a problem with the sequence in this current project I am working on.
Any help you could give would be appreciated more than I can express.

Have you set the sequence you're trying to play to DV-NTSC? It sounds to me like you're trying to play a sequence that is not a stock DV sequence through a DV device.
Try creating a new DV-NTSC sequence, copying all the clips from your current sequence, and pasting them into the new sequence.

Display size external Monitor

The resolution of the YOGA 13" display is that high, that one has to use 200% size in Windows 8.x. If I connect to an external monitor with HD resolution this is to big. I have to change it and make a re-login. This is very time consuming and annoying.
How can I resolve this problem?

Ya, that's going to be an issue. The Mac (when set not to mirror) will think you're wanting to use that extra monitor as extra space (i.e. extends the desktop onto it). In mirror mode, the resoluton MUST be matched on both (I think it's a limitation of the OS because I can do this all day long on Windows). The only other solution would be to hook up multiple monitors and a physical keyboard/mouse so that you can close the clamshell and use just the external monitors. Don't quote me on this, but you may be able to mirror at that point across two external monitors. The problem comes into play when you try to do that along with the built-in laptop display.
