External monitor resultion problem: black borders

I use a Hanns-G HW191D 19" external flatscreen with my Macbook. It is a wide screen with 1440x900. The problem is that I cannot use all of that space when I'm in the Mac OS. I can use it (to the edges of the screen) when I use Boot Camp in Windows XP with the same Macbook.
When I'm in the Mac OS (which is about 99.9999% of the time of course), I have about about an inch of black border all the way around my desktop -- as if it cannot scale up to the full size of the screen.
In my system prefs, I have my Displays set to:
1440 x 900
Millions of colors
60 Hertz
I'm connecting via the VGA connector (since that's all I have to work with).
The monitor itself has some onscreen controls, but nothing that can make the image bigger.
Okay one other thing, I got this Macbook a long time ago -- almost two years. I got the external monitor for it about a year and a half ago. This problem existed from the first time I connected the monitor -- I tried to figure it out but couldn't and didn't think to try this forum. So I've been living with it since then (ug).
Macizoids! Help!

Did it develop around the same time, after you downloaded the security update?

External Monitor Shows Only Black Screen ??

Recently, my PowerBook G4 12" stopped working properly with my external monitor. My external monitor is a Dell 2005FPW that is connected to my laptop via a mini-DVI adapter, a VGA cable to the VGA port on the 2005FPW. When connected to the laptop, the 2005FPW goes black; otherwise, the monitor shows it's "rest" screen which is a bouncing color bar.
This system has worked without problems for years. I changed nothing in the configuration and (possible red herring) the only "event" prior to the problem developing was that I installed the "Security Update 2008-005 (PowerPC) v 1.0".
I have confirmed that the monitor and VGA cable are working with my wife's laptop.
Today, I replaced the mini-DVI to VGA adapter, and the problem hasn't gone away.
Any suggestions?

No preview on external monitor and histograms black?

Hi, im having a problem with previewing. In the upper left room i see the footage (also changing when grading) but the rest of the rooms and my preview monitor are black. Histograms are not working.
Rendering and sending it to final cut works.
Im using a blackmagic decklink card for the output of the external monitor. Footage comes from the RED, 2K.
A colleague has the same mac pro but is using the older cinema screens. He has no problems. I use the new 24". Could that be the problem?
Does anyone has a idea what is going wrong?
Thanks.

Mini DVI to external monitor (VGA) problem/firmware update does nothing

Hi,
Four months ago I bought a new white 13-inch Macbook (2006 model I believe) along with a handy mini-DVI - VGA adapter. I used a Hanns-G HU196D external monitor which worked fine for a couple of months but then stopped, and had the same problem with a (much cheaper) 'LiteView' monitor. I find it bizarre how they work absolutely fine and then stop, with no damage to the adapter, cable or ports. I've since bought a new adapter and cables + trying out a different monitor and still the same problem...
I've installed a firmware update that describes the exact symptoms, but it's done nothing. Can anyone help me resolve my issue?? It's still under warranty so is it an unusual problem that'll need to be fixed by Apple?
Thanks

Are you using the mini DVI to DVI followed by a DVI to VGA adapter? That may not work if the mini DVI to DVI adapter does not pass analog video. If that is the case, you need the mini DVI to VGA adapter:

External monitor resolution problem

Hi,
My external monitor's resolution is 1920 x 1080 but the highest I see in resolutions' list is 1600 X 900 or 1344 x 1008. I am connecting my MacBook snow leopard to Asus ML249H with HDMI cable. I've tried some suggestions that were posted for Mac Pro but nothing worked. Can anyone help? Thanks!

FCP DV Output to External Monitor Quality Problem

Hi there, I'm using Final Cut Pro HD from Final Cut Studio 2, and I'm having a problem with the quality of the image on my external monitor. I have checked all the settings etc... for external video and they all seem right, but when I play the video in my canvas the signal into my camera lcd and onto my ntsc monitor is not correct. It plays the video; however, it also has a constant stream of large grey squares flashing across the TV. I would say 50% of the output signal is my video, and then 50% of the screen is taken up by these large moving grey squares.
I have all my windows fit to screen, I've choosen the Apple FireWire NTSC option in the A/V settings, and I have the all frames checked in the View tab.
It seems like only half of the signal is making it's way from FCP to my camcorder. At first I thought it was my NTSC monitor, but when I saw that the grey squares are also showing up in my camcorder's lcd screen I figured that it must be a problem coming from FCP.
Any help with this would be greatly appreciated. Thanks so much!

You'd think so, but I'd try another anyway...
Another thing that might be amiss is the power management on your Mac. There is a PMU button on the motherboard of your machine you can reset. You need to unplug it from power first however. It's under the fan you can remove to add RAM...

External monitor resolution problems with Mountain Lion

I have a problem with my external monitor (Samsung LS19B150NS) and Mountain Lion (running on unibody Mac Mini). Each time I reboot OSX the resolution get reset from native 1366 x 768 to something lower. The display is connected via DisplayPort-to-VGA adapter. Some observations:
- I tried selecting "Best for..." option or "Scaled" (set on 1366 x 768 or 1360 x 768). The problem is still there
- Sometimes resoltuion might stay alright for several reboots, but then the problem re-appears again
- Sleep mode doesn't reset resolution
- Other monitors work fine via the same adapter
- The Samsung LS19B150NS work perfectly well with other Win PCs
Any suggestions how to fix it?

T400- make the external monitor primary problem.

I use T400 and Acer p223w monitor.
From some reason I cannot make the external monitor to be the primary monitor.
Using the Presentation Doctor I have the option to define the external monitor as the primary but when I test it, it says that I have illegal parameters of color depth and resolution.
The problem is that the parameters I use are the parameters currently defined on the two monitors (which mean the monitors have no problem working that way).
Any other color depth resolution combination won’t solve the problem.
On the other hand using the same parameters if I configure the laptop monitor to be the primary everything works just fine.
Any idea what causing it and how to solve it will be highly appreciated.

Since I have a German Windows client I can only guess the wording on the english client, but try the following, which worked on my T500:
Bring up the mobility center by pressing Win+X
Click the button to connect an external monitor
Choose to use the external monitor as the only display
Now that the external monitor is the only display, it is also primary of course. Now you can use the normal windows display dialog (Right-Click on desktop -> Configure -> Display) to extend the desktop to the internal display which will be secondary then
done
In my case windows remembers this configuration and you do not have to do these steps again after reboot or when you reconnect the external monitor.
Hope this helps for the T400, too.

External monitor resolution problem on MacBook PRO

MacBook Pro mid 2012. Samsung 204Ts Monitor is not working in full res. However it works in full resolution on Mac Mini (Core 2 Duo)

In order to get the external monitor's native resolution uncheck use mirrored mode in your display preferences. If you are using mirrored mode then your computer's display, including its resolution is used on the external monitor,

Fullscreen video playback on external monitor (overlay problem?)

I want to watch videopodcasts via iTunes fullscreen on my external Monitor/TV. It works fine with Quicktime and WindowsMediaPlayer but iTunes doesn't play my Videos in Fullscreen on my external Monitor.
I had the idea it is because the overlay mode isn't siwtched on but I can't find where to setup the display mode of video playback in iTunes.
Can anybody help me?
Bernd.

oh, no...
i thouhght the iTunes Videoplayback would rely on Quicktime and thus it would be possible.
isn't there any other possibilty?

External Monitor Playback Problem

Hey all,
I recently updated my machine to FCS2. I've had all of my other editors on it since it came out, but I left my machine alone until I knew it was safe to have all of us going on the new system.
Everything is fine with the software, but I can't get my external monitor to play back in real time. I'm going through a JVC SR-DVM700 from the rear firewire port. It will log and capture fine, and it will show the current fram when I'm in the timeline, but will not play back in real time - even when it's fully rendered. I have the view>external video set to All frames, and still no dice. I've tried to refresh video devices, and got nuthin'....
Anyone?

If you have ever enabled "desktop preview" or such, that can mess up the external monitor I have found. However, just make sure that is turned off, refresh external, etc.

External monitor resolution problems

According to System Preferences, I currently have a maximum resolution of 1280x800 on my built-in monitor.   When I hook up a my large external monitor with higher resolution capabilities, I don't seem to be able to use the whole screen size and I'm losing about 4" of space that I desperately need!

Each has its limitations. Mirroring limits the external to the internal's max resolution. Extended desktop doesn't allow you to mirror. You're going to have to decide which you like better.
I'm still not clear what you're seeing in extended desktop. You should be able to get a whole desktop's worth of display on the external display, not just half of it. Open display prefs > arrangement again and drag the menu bar from the little/built in display over to the big one/external display.

After OSX.4.11 update external monitor unresponsive+problems w/sleep etc

I've read some of the recent display problems. Here is my problem and what I've tried, my problem just started 6 hrs ago. I updated to OSX.4.11 a few days ago - eveything worked fine, yesterday I reinstalled epson printer driver as it was crashing and also yesterday I worked for several hours in iMovie 08. Nothing else unusual. This is STRANGE!
Today went to wake my MBP, 2.4 GHZ, 4GB ram, Cinema display 20", wireless keyboard/mouse up from sleep to check mail. Cinema display flickered and then changed to dark blue solid - and unresponsive. Couldn't get external display to function. Never had any problems with it. Tried to restart everything, unplug all cords, etc. Everything started up I got the log in password screen on my external cinema display - typed in my password - then saw my desktop photo for a second and the cinema display flickered to dark blue again and wouldn't change. It was unable to mount the desktop.
I went to my MPB while still connected got the screen on the MBP and saw the desktop but there were sort of black lines through the names of my folder files on my desktop. I then disconnected the cinema display, restarted just the MBP and the screen (of the MBP) that mounted was perfectly normal - no black lines through file folder names.
Then I tried various things. I assumed my cinema display was broken (almost 3 years old). But then I hooked my MBP up to an old 20" cinema display (they kind with 4:5 ratio and plastic all around), I think it uses some kind of converter to the DVI port anyway my MPB worked with that old display fine, desktop fine, but it would not stay asleep - no matter what I tried. I've never had that problem ever before.
Then I took the "newer" 3 year old cinema display (aluminum one) that I use all the time I I suspected was busted and hooked it up to my old Powerbook G4. And it mounted the desktop and worked fine!! The G4 just got updated to 10.4.11. Interesting thing is though when I closed the lid which usually made the G4 PB sleep it shut it down instead of making it sleep. Very odd.
Then I ran down to Apple store and bought new version of Disk Warrior and ran it on my MBP. I've never had anything Disk Warrior couldn't fix. It rebuilt my directory. I then hooked the MBP back up to the cinema display (aluminum) and the same thing happened I got my log in screen after startup, logged in password saw the photo desktop for a second then the cinema display went back to a dark blue screen that was unresponsive. I then ran Disk Warrior again with the cinema display attached to see what would happen. Disk Warrior mounted and I saw the whole process on the cinema display. The cinema display will mount disk warrior but it will not mount the MBP desktop as of 6 hours ago.
I then read these recent posts and tried a "safe" boot. I got my MBP desktop on the cinema display (aluminum) but as soon as I clicked on system prefs the cinema display went to dark blue unresponsive screen.
But the same cinema display (aluminum) works fine with the Powerbook G4 except for some issue with sleep
And the MBP works with an old plastic cinema display except again, it won't stay asleep.
But the MBP and the aluminum cinema display that I've been using together for my photo/video editing for 4 months straight now and I've never had any problems with - they won't work together as of 6 hours ago. That is when I get the dark blue unresponsive screen on the cinema display (aluminum).
Upshot is:
1) Something is up with sleep mode and the OS X.4.11 update on 2 different machines (G4 PB and MBP)
2) Something is affecting the way both the MBP and the Powerbook react with both my cinema displays. The MBP and the 20" aluminum Cinema display are the ones I need to work with and the ones that as of 6 hours ago just lock up in cinema display dark blue screen (almost black but not quite).
Is this a problem with sleep, startup or DVI output and OS X.4.11?
What can I do about it? I need to use my 20" aluminum cinema display it is clearly the better one of my 2 cinema displays. And even if I switch to my 20" older plastic apple cinema display the computer won't stay asleep any longer?
Please, Please I need some help.
Also since this is happening on 2 separate machines and 2 separate monitors there is something odd going on.
Apple tech people, is there a major problem with .11 and sleep and external displays?
Sincere Thanks, Carol
PS Note, I tried all this numerous times with both bluetooth and regular wired keyboards/mice along with MBP and PB keypads.

Sorry please forgive me, I'm so exhausted I posted this in MacBook instead of MacBook Pro, I'll try to move it but if I can't I'll try to copy it and post in MacBook Pro, regardless I think there is a problem with the .11 update.
Thanks, C

External Monitor Flashing to Black

PowerBook G4 15" 1.67 GHz with 2 GB DDR2 SDRAM running OS X10.4.11.
I'm attaching a Samsung SyncMaster 205BW using DVI cable that came with monitor. My Mac is recognizing this as a SyncMaster and I am using the display settings it defaulted to. I am using the notebook's built-in screen at same time as the SyncMaster (not mirroring). In the displays preference pane I have the monitors arranged with the SyncMaster above the notebook's display. The menu bar is at the top of the SyncMaster and the dock is at the bottom of the notebook display.
For some reason, after a few minutes of use the SyncMaster will start flashing to a black (blank?) screen as if it is not receiving a signal. It will then come back after about a second. Once it starts, the problem becomes more and more frequent as I use the monitor. However; if I unplug the DVI cord from the PowerBook and wait for the built-in screen to reset, then plug the DVI cord back into the Mac, the problem will go away again for several minutes.
I have not been able to duplicate any particular action or application that triggers this.
Any and all suggestions for fixing this are appreciated!

Hi DJ
I had a similar problem with my acer display, it showed up, that it lost synchronization of the refresh rate somehow sometimes. For me the fix was to download [SwitchRes|http://www.switchres.info/html/SRX/DL.shtml], setting some different vertical refresh rates (from 60Hz to 68Hz) there, restarting the Book and then selecting 62Hz within the SysPrefs/Displays window. The nominal refresh rate of my display is 60Hz but this ended with a total blackout, it works steady with 62Hz. After this procedure I could delete SwitchRes and ApplicationEnhancer that came with it, the custom refresh rates remained. Be aware that ApplicationEnhancer caused some troubles with OSX 10.5.
Good Luck P
