Blank external Monitor

When I connect the laptop to an external Apple Monitor everything works except I get a blank screen. It goes into duo monitor mode and even gives me the preferences and the information in "about this Mac' but the display is blank. Ideas?

No, I can hook up my old G4 laptop and it works.

Blank external monitor - XP

I have an external monitor - HP w2207h, flat panel. When booting into the Mac OS this monitor works fine. When Windows XP is running this external monitor is not available. However, when booting into XP, the initial Windows XP splash screen (the black one with the Windows logo and blue, short progress bar at bottom center) displays on both my MBP screen and my external monitor. However, once the XP boot process passes this point, the external monitor displays a message saying "monitor going to sleep," goes blank and stays blank. I have checked all of my video/display settings as best I can. I have gone through the Trouble Shooting steps provided by Windows and still have been unable to get the external monitor to work.
Any ideas or suggestions would be greatly appreciated.
Sincerely,
Steve

I've got the exact same issue here on my T60. I've reinstalled all of the ATI drivers from the Lenovo site. I'm still staring at a blank second monitor. My laptop detects the alalog connection, but does not recognize the Digital connection. I've tried both with and without the docking station. Any help is appreciated.

Enhanced USB Replicator - blank external monitor

I have a new SL500 with an Enhanced USB Port Replicator. When I install the port replicator drivers, the external monitor works fine the first time and there is an icon for "Lenovo Display Adapter" in the system tray. But after a reboot the external monitor is blank and there is no icon for "Lenovo Display Adapter" in the system tray. I tried downloading the latest Enhanced USB Port Replicator drivers - no help; and I tried downloading DisplayLink drivers - no help. Any ideas??? Thanks
Mike

My external monitor seems to be working now. I'm not sure if this is what fixed it, but this is what I did:
Installed the DisplayLink driver (this driver made a big difference in the clarity of my external monitor)
After installing the DisplayLink driver, I noticed an error in the Administrative Events Log (in Vista: Control Panel - Computer Management - System Tools - Event Viewer - Custom Views - Administrative Events). The error was:
The DisplayLink Service service is marked as an interactive service. However, the system is configured to not allow interactive services. This service may not function properly.
So, I changed the setting for Interactive Service. In Vista, go to Control Panel - Computer Management - Services and Applications - Services. Find the Service called, Interactive Services Detection. Open it up and change the Startup Type field to Automatic (it was previously set to manual).
After doing this, my external monitor is working nicely even after a reboot.

I connected an external monitor to my MacBook Pro, but it doesn't open any programs. It Just sits there with a blank screen. How do I get it to open programs and act like a monitor?

Dear Jean:
It sounds like you are trying to get your external monitor to act as the primary viewing screen. For example it would have your Doc, Icons, Etc. In order to make the external monitor the primary screen you have to:
Open System Preferences.
Choose the Displays Icon
There will be several tabs to choose from pick Arrangement
Drag the toolbar to desired display
Let me know if this helps at all!

How to blank laptop screen when using external monitor/

Hi there
I need some help with figuring out how to configure my xorg.conf for my Arch Linux 64 bit installation on a HP Pavilion dv 5000 laptop so that I can automatically blank my laptop screen when using an external monitor. I have Arch Linux installed along with Ubuntu Feisty. In Ubuntu my external monitor (Viewsonic 1912WB) was not detected at the time of installation but with the native 1280X800 resolution that is good for the laptop takes effect for the external monitor automatically when the external monitor is plugged in. The laptop monitor goes blank when the external monitor is plugged in.
In my Arch Linux installation I have not been able to configure a dual head configuration using the ATI Radeon drivers (fglrx). I have the native 1280X800 resolution set up for the laptop monitor and this resolution takes effect for the external monitor also. However the laptop monitor also continues to function when the external monitor is plugged in. I would like to blank the laptop monitor when using the external monitor.
I am attaching my Arch Linux xorg.conf and the Ubuntu xorg.conf below. Thanks for anyone who can help, I am having a lot of difficulty in figuring out how to set up xorg.conf among all the things that I have had to learn so far in Linux and I am a relative newcomer to the whole thing. I have tried to compare the two xorg.conf files and edit my Arch xorg.conf in accordance with the Ubuntu one but it did not work and I keep getting errors!
I am using XFCE as my Desktop environment.

Xrandr 1.2 provides means for this. But today the only supported configuration is xorg-server-1.3 + xf86-video-intel-2.0. So for Radeon you'll have to wait for drivers that support Randr 1.2.
On my laptop (Thinkpad x60s) that would be:
xrandr --output VGA --auto
xrandr --output LVDS --off

Dual monitor (w/laptop): external monitor is blank.

Hi! just installed arch for the first time a day ago. Right now what I'm working on is on getting my second monitor running (mostly for development purposes... and movies ^__^).
I'm using Arch64 with the open ATI driver and KDE. Whenever I connect the external monitor, the monitor seems to detect a connection occurred (the "check video cable" message disappears when I connect it and comes back when I disconnect it), and so does KDE. When I open my display settings, it tells me a new monitor was connected and asks me if I want to configure it.
Then I choose to configure and use the two monitors giving the following screens (right now I'm at college testing with monitors in there, thus the low resolution, but behavior seems to be exactly the same):
(EDIT: resized. In case of wishing to read full images, just take the "resized/" out of the URI)
However pretty the full screenshot looks like (... I just mean that even if it looks like the second monitor is working), the monitor remains blank.
Using arandr (xrandr's gui), it is exactly the same result. I might be doing something wrong (almost certainly I am ) (EDIT: decided it was a good idea to show what I did with xrandr).
In /home/<myuser>/.xinitrc my file looks like this:
#!/bin/sh
# ~/.xinitrc
# Executed by startx (run your window manager from here)
xrandr --output VGA-0 --mode 1440x900 --pos 1600x0 --rotate normal --output LVDS --mode 1600x900 --pos 0x0 --rotate normal --output HDMI-0 --off
if [ -d /etc/X11/xinit/xinitrc.d ]; then
for f in /etc/X11/xinit/xinitrc.d/*; do
[ -x "$f" ] && . "$f"
done
unset f
fi
exec ck-launch-session startkde
# exec gnome-session
# exec startkde
# exec startxfce4
# ...or the Window Manager of your choice
The laptop's model is Toshiba Satellite L775d. I'm not sure what other information should be required in this situation, but I will be loving to give anything that isn't compromising
Thank you!
(PS: so far Arch has treated me nicely let's see for how long)

I wondered the same. I initially only used KDE for it (that's how it worked in other distros, but I'm guessing Fedora and Kubuntu have way more stuff on top). I moved to xrandr later after searching for options and I did select "Ignore" when KDE asked me to configure and just went ahead with xrandr. The same still happens.
Thanks, I hope I gave the right information.
EDIT: Adding some extra information. I tried rebooting with the CRT cable connected. When the kernel initiated its loading, the messages only appeared on the external monitor. It was afterwards (it was pretty quick, but I will assume it was when radeon's modeset hit) that the external monitor went blank again and, in that situation, the laptop's monitor went blank (so none of the two monitors worked... and I was so hopeful!)

External monitor w/ mbp - display has 1" border that is blank -- doesn't fill out screen can this be adjusted?

how to configure external monitor so that content fills the screen. blank border around edges aren't taking advantage of full screen and is annoying.
thanks for any help you can provide

Uncheck Mirrored, you'll then be in Extended mode:

Blank screen Envy 15 despite reset and external monitor

HP Envy 15 J112TX notebook has worked well for a week. Windows 8. The screen is black but can hear the fan going. Hard reset didn't help. External monitor didn't connect - it said to check the video connection. The cord was connected HDMI to DVI. Did another reset. Now i have switched it on and off a few times so that when i switch it on after a minute it will make asmall pop sound and then the fan stops making noise and it won't switch off despite holding dow the power button for a minute.
I disabled the nvidia graphics card a few days ago to try and save on power as it also has an intel graphics card. But it worked fine for a couple of days after i did that.

Hi @salsa7 ,
I understand that you cannot get your HP Envy 15-j112tx Notebook PC will not boot up for you. I will try my best to help you with this issue.
Here is a document for Blank Screen LED Error Codes that may help us determine what is causing this issue.
I hope this helps, please let me know how it goes.
Thank you and have a great day!

The DVD player was connected to a PAL TV, but it's OK because the DVD player can read anything. I know because I've watched NTSC as well as PAL dvd movies before.
The Canon XL2 the Mac is connected to, via Firewire, is NTSC, connected via RCA to the PAL TV. Which means the signal I'm watching is Black & White... (I know this sounds WEIRD)... but it's O.K. because what I'm really checking as I edit is the interlacing problem that I got when playing the DVD on the dvd player.... : the BAD problem.
How bad? Really bad. Any sudden movement, or panning of objects with vertical lines, like a painting or a building looks all wobbly and curvey and blurry and wrong, which is unnacceptable for the project I'm doing, as it is a professional work (Meaning that I'm charging money for it, despite the crazy assemble of different products and formats I'm using).
I've gotten things that look good before, but never on Final Cut Pro.. I'm new to the program, and to Mac, and this is the first video I'm exporting to a DVD on this platform.

Powerbook G4 15" screen blank, can't connect to external monitor

Hi,
I've had a 15" Powerbook G4 for about 2 years now, but about a year ago, I switched it on and the display was white. I could hear the startup chime, and everything seemed to be working fine underneath, but the screen was just white.
So, recently I took it to an Apple store and in the end, they told me that the LCD was broken and that they would have to replace it for the Powerbook to work properly. As this would cost over £400, which I can't afford, I just decided to try and use an external monitor with it, as they had done in the store to check it.
So, I bought a DVI-VGA adapter from eBay, received it this morning, and tried to connect the Powerbook to my CRT monitor using the adapter.
Basically, I plugged the VGA cable from the monitor into the adapter, and plugged that into the Powerbook.
However, the external monitor just stays blank, as if it isn't connected to the Powerbook.
Please, can you tell me if I'm doing anything wrong, and if not, suggest why it might not be working.
Thanks,
sharkofmirkwood

Satellite Pro 4030 boots with blank screen - works OK on an external monitor

My sat pro 4030, funning W98SE, boots to a blank, white screen. When I press the lid closer or use Fn/F5 it goes black. It works OK on an external monitor.

Hi Robert,
If your display appears correctly on an external monitor then it indicates that your graohics chip is still working correctly, so you problem must lie with the LCD panel itself, the FL Inverter, or the connection cable to the main board. I would recommend that you contact an Authorised Service Partner who can carry out further tests to diagnose the fault.

External monitor recognized but blank

Trying to hook my Dell U2410 up as the main monitor. It sees it just fine and I can mess wit the settings, but the screen is blank. It does this in OSX and Win7 on the bootcamp side.
I'm running out of the display port to dvi.
I know the monitor is good as it is my primary desktop display.
Any ideas?

In the external monitor preference panel have you set it to NTSC at 60Hz ?
If you switch back and forth between Mirror and Extended Desktop does it flash at all ?

MacBook Pro 9,1 External Monitor Blanks Out?

I have a 15-inch, Mid 2012 MacBook Pro with a 2.3 GHz i7 processor, which I purchased last December. For some reason my external monitors blank out about 1-3 times per day. As far as I can tell the symptons are not reproducable. It just seems to randomly happen.
Has anyone else had this problem and if so, what was the solution?
Thanks!

Are you sure it is not a hardware problem? A bad cable or a poor connection?
I would try this after eliminating hardware causes.
Go to System Preferences / Displays. Verify the settings are correct, and correct or not change them arbitrarily - just move the settings back and forth - and then set them back where you want them.
Now reset the PRAM:
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

External monitor goes blank

The backlight went out on my Toshiba laptop so I hooked up a new(er) flat screen monitor to it. The Windows XP startup windows _begins_ but never gets _to_ my desktop. Windows XP startup runs for about 20 seconds and then the monitor reads 'no signal.'
I simply want to access information (files, folders or photos) on the Toshiba before I sent it to laptop paradise forever.

Hi
Usually you should be able to switch to external monitor using the key combination FN + F5.
I think this key combination would not work in safe mode since safe mode loads only some essential system processes.
So if you are able to boot the Windows OS in normal mode then check FN + F5
You could also try to change the display settings in graphic display properties -> last tab Settings (to get the display properties click right on desktop and choose Properties )

External monitor going blank!

Hello,
I have a exrernal Dell 24' monitor that has been working 100% ok for years on my macbook now am running 10.7.2.
I use the mac in clam mode and using the Dell as the main monitor.
Today I have a problem as after around 10mins of uses the monitor went to sleep! pluging the monitor in to other devices helped to provide its fine.
I rebooted the macbook and still the monitor would not come on!
I done the Shift + Control and power, Command + Option + R+P and the booted in to safe mode and this restored the display :-)
But it kepts on happing every few hours and even sometime the display will come it by its self!
Are odd!
Please can someone help?

If you have another computer or device that could you attach to the monitor to check if it does it over multiple devices?
Also do you have another external monitor or projector to hook up and see if the same thing happens there?
Rule out if it's the MB or if it's the monitor. If you're still under AppleCare, or even if you're not, and are unable to do the above then I would suggest getting it taken in. Schedule a Genius bar appointment to get it looked at.
