My external monitor and MacBook Pro screen turn different colours and freeze while in use - only restarting the computer will refresh the display. Is there a way this can be fixed? It is happening more and more frequently.

The monitor is Philips brand and works perfectly fine usually. Every now and again it will happen mid-use and I have to constantly re-start my laptop.

The F7 key should also toggle between extended desktop and mirroring. If you open the lid on the PB, you should see that the F7 key is imprinted with two overlapping rectangles. That's supposed to represent the mirroring function and pressing the key should toggle the function (unless you had previously turned off the function keys).

HT3964 connected new external monitor to macbook pro, was working but now have no power, black screen in laptop. monitor purchased with advice from tech and set up also. Worked fine for an hour and then quit

Have just connected a viewsonic external monitor to macbook pro 10.6.8, had everything up and running fine for about an hour then the macbook quit. No power (ws running off power source) Have I killed my macbook? Help!

Aha, all is good.
I went to Library/ColorSync/Profiles/Displays
and to home/Library/ColorSync/Profiles/Displays
and deleted all SyncMaster.icc files. I did leave behind one SyncMaster file in the home/../Displays which had an old date and I new was ok.
Rebooted, plugged in SyncMaster, and a new icc file was automatically created in the /Library/../Displays folder.
My display works normally, now.

Using the MacBook Pro with external Monitor and Keyboard

This may be a dumb question, but here it goes anyway:
Can I use the MacBook Pro with an external monitor and a bluetooth keyboard and mouse without having it opened all of the time ?
I am planning to buy a MacBook for my wife and most of the time she will be using it at her home office.
I don't want her to use the computer opened all of the time when she is actually looking at the separate screen and using a separate keyboard. Having the laptop opened will only accumulate dust and reduce the lifetime of the built in screen.
What I would actually need is a kind of "docking station", but Apple doesn't make that - I know.
So can the MacBook at least be operated without the internal screen powered on while it is closed?
Thanks for your help

MacBook Pro with external monitor and keyboard.

Hello, everyone.
I've tried to find the answer for this question but haven't found a clear answer with my Google search.
My older Powerbook G4 will not allow me to work with an external monitor and keyboard with the screen in a closed position. I am about to purchase a new MacBook Pro and would like to be able to use it at home with a larger monitor and keyboard but with the lid closed and its built-in screen turned off. Can this be done ?
How can a MacBook Pro be used (turned-on) with external monitor and keyboard while the lid is closed and the its screen is off ?
Thank you in advance for your answers.
Joseph

Hi Niel,
I have the same problem with my MacBook and I followed the instructions you posted. My issue is that when the computer wakes up after clicking the buttons on the keyboard it then quickly goes back to sleep. I can't seem to keep it awake when the lid is closed. I've been searching for an answer without any luck. Any idea how to solve this problem?
Thanks!
P.S. After I finished posting this message I figured out my problem. While fiddling with my computer and monitor, I inadvertently disconnected the power. After reconnecting the power, I was able to wake my computer and keep it awake. A note to other people having this issue: the computer must be connected to a power outlet to run in closed mode.

External monitor with MacBook Pro

I have a new Macbook Pro and have it hooked up to an external monitor and an USB Apple keyboard in my home office. How am I able to power the laptop on without opening the display and have it display only on my external display? When I am at home I'd like to use my external monitor and not my Macbook display.

Having the computer with the lid closed is dangerous cause even when just browsing the web with flash content it starts heating up and I've heard about casess of melted displays. Besides, the wifi strength is reduced and you can't use the keyboard and the trackpad.
So, for Lion users, it's possible to just use the external display with the lid open:
1. In Mission Control Preferences activate one Hot Corner to put the display to sleep.
2. Connect the external monitor and plug in the power source to your computer.
3. Move the mouse to the Hot Corner to put the display to sleep.
4. Close the lid and wait a few seconds.
5. Open the lid and voila!
Take care!

No video when using external monitor and resuming from sleep.

I know some people were having problems with the new MacBooks, but I guess the Mac driver fixed something. However, when I'm in Windows and have my Dell 24" hooked up to the Mini DisplayPort -> DVI adapter, I cannot resume from sleep. The monitor will turn on, but I can't get an image on it.
In MacOS it seems to resume from sleep fine, but not in Windows. Anyone else seeing this?
Thanks!

Is no one else getting this error? Does anyone have any issues when their MacBook is hooked up to an external monitor and it goes to sleep?

How to connect an external monitor to macbook pro. The monitor has no usb connector without a usb

How to connect an external monitor to macbook pro. The monitor has no usb connecter, only a port.

Most MacBook Pro models have a Mini DVI port, a Mini DisplayPort or a ThunderBolt port for connecting an external display. USB does not have enough bandwidth to support a responsive display connection.
What model MacBook Pro do you have, by year, CPU speed or MacBook Pro 3.1 designation?

FCP Problem with Firewire output to external monitor and speaker ???Help

i have a g5 powermac. the problem is when using Final cut pro 4hd. when i output my work through firewire to my external monitor and speaker i have a problem with the audio signal. Theres feedback/noise/hiss from the speakers. The firewire connects to DSR-11 vtr deck which feeds my monitor and speakers. it only happens when in FCP is set to A/V firewire output. does not happen if Video output is not set to firewire.
I Diagnosis is that it is not my dsr-11 deck or firewire i've ruled those out. The problem is either FCP software or Hardware problem with my G5
Does anyone have a similar problem. please respone, i will try to answer any respones,
Thanks
powermac g5 powermac

CaptM
From the firewire that feeds the dsr-11. on the output, i use s-video cable to my monitor (sony pvm-14l) and High Quality rca cables thet feed the audio to the Roland Speakers.
I've changed all wires and still have audio problem. I,ve changed my Dsr-11 deck to my camcorder and still have the problem.
If any of u guys use FCP The problem happens When I select view> external Monitor > and select firewire for Audio/ and video. I have never changed my editing habits, something just went wrong with the signal, I think its a Hardware problem with the firewire connection. I'm Going to have to bring this to a Apple Service Center In my local area one day.

Using the GT70 with external monitor and lid closed

I wasn't sure where to post this question.
I have several laptops and use external monitors. I close the lid on the laptops and the display continues to work.
On the GT70, the system shuts down. It won't allow me to use the external keyboard and mouse or display the session.
Any suggestions if there is a configuration option to allow the GT70 to continue to function with external monitor and lid closed.

Yup. This is a windows setting. You need to go into your control panel -> power options -> "Choose when the computer sleeps" and "Choose what closing the lid does"
That should solve the problem. I currently have my GT70 hooked up to a 42" TV and I can close the lid and it stays on and the TV continues displaying as well. No problems. =]

Using external monitor with macbook pro?

Can someone tell me how to get my Dell desktop monitor to work with my MBPro? I connected with usb/vga cable; i have a pic on the external monitor and the mouse pointer will move about the screen, but that's it; no funcitonality. I don't know what do do next? Settings?

It sounds like it's working perfectly, you have a functioning image and pointer. But you may be expecting to see some of your windows. It sounds like the monitor is connected in Extended Desktop mode, which means it's working as an additional area to your existing desktop, like sliding another table next to yours. So, if you want to see some windows and programs over on the new monitor, you should drag them there. Also, open your Displays system preference to see this and change settings.
If you expected to see the same image on both your monitors, you need to switch to Mirrored display. If there is a Displays icon on your menu bar, you can switch it there.

External Monitor and LXDE

I run Arch + LXDE on my laptop and everything works great. Recently, I attempted to attach my laptop to an external monitor and use lxrandr to output only to the external. When I first tried it, the output worked fine but I was unable to adjust the resolution on the external monitor to anything greater than the best resolution I can get with my laptop. After restarting X, though, I was able to get max possible resolution on the external. However, this does not happen automatically, and every time I attach the monitor I have to reset the resolution to the best possible. Also, PCManFM only displays the desktop on a portion of my monitor equivalent to the laptop resolution (1280x800) even though the laptop monitor is disabled by lxrandr. The rest of the desktop is just openbox; when I right click on it, I get the openbox menu. Furthermore, when I attempt to switch to an agetty, the display is not aligned and most of the left side of the output is cut off. However, if I open the laptop, the agetty output works nicely there.
The agetty problem doesn't surprise me because that has nothing to do with Xorg, but it would be really nice if everything just worked. I have tried looking for similar problems (and solutions), but I can find very little information. I would like to have PCManFM put the desktop on the whole display, I would like to have the best resolution automatically when I plug in the external, and (maybe) I would like to be able to use the agetty terminals when I just want to work from the terminal.
Thanks!

I want to avoid setting up a xorg.conf file, and arandr works pretty much the same way as lxrandr. So I decided to write a simple script that I could run at startup to automatically set the resolution of all attached monitors to the maximum possible. Here is the script, and I can run it from /etc/xdg/lxsession/LXDE/autostart:
#!/bin/bash
query=`xrandr -q 2>/dev/null`
screens=`echo "${query}" | grep '^[A-Za-z].*' | sed -e '/^Screen.*/d' -e 's/[ \t].*$//g'`
c=0
for s in $screens; do
screenarr[$c]=$s
c=$(($c+1))
done
displaylines=`echo "${query}" | grep -n '^[A-Za-z].*' | sed -e '/^[0-9]:Screen.*/d' -e 's/:.*//g'`
c=0
for i in $displaylines; do
resline=$(($i+1))
res=`echo "${query}" | grep -n '.*' | sed -e "/^$resline:[ \t].*[0-9]/!d" -e 's/^[0-9].*: *//' -e 's/ .*//'`
if [ "$res" != "" ]; then
xrandr --output ${screenarr[$c]} --mode ${res} 2>/dev/null
fi
c=$(($c+1))
done
I wrote this really quickly so if anyone has an suggestions for improvement that would be great. I am hoping to generalize this so that you can pass it simple parameters to have some control as to how your monitors are configured. Also, if you have a better way to extract the monitor information than from xrandr -q and regex that would be a huge improvement.
When run from autostart before PCManFM, PCManFM fills the full screen with the desktop.

Preventing SLEEP when using External Monitor and Keyboard

Prior to Leopard, whenever I had an external monitor and keyboard attached and closed the MacbookPro lid the system would not go into SLEEP mode. Now it does.
What's to be done to prevent this from happening?

PS.... when this last occurred, the backup drive for Time Machine disconneted when SLEEP was invoke by closing the lid and did not reconnect when the system restarted.
I also received a 'warning' that a device was not disconnected properly.

External Monitor on Macbook Pro freezes after deleting old profiles

Environment:
15 inch MacBook Pro, Mid 2010, 2.4 GHz, 8GB, NVIDIA GeForce graphics
Yosemite 10.10.1
External Monitor: Samsung SyncMaster 245T running in Extended Mode with the laptop
I have been using the above setup for several years with no issues. Yesterday I did a calibration of the external SyncMaster monitor with Datacolor Spyder3 as I have done many times in the past. The calibration was saved, but an error message flashed by before the file was saved. Checking with the ColorSync utility, the new saved colorspace appeared somewhat smaller than the last one.
I noticed that I had too many old profiles from previous calibrations still there, so I tried cleaning the directory up. I opened System Pref/Display/Color, clicked on an unwanted profile and delete the profile, and reset it to the profile that I wanted. Repeated this a few times and the SyncMaster appeared to be good.
Now I tried the same with the Macbook. Fine, deleted a few profiles but something now messed up the SyncMaster. It colors, including the dock, contorted to an ugly mess. Cursor changed to a spinning wheel, and I could not click or select anything either on the SyncMaster or the Mac. Rebooted, pulling the Syncmaster adapter out of the mac. Everything good, until I plug the Syncmaster back in, and I am back to the spinning wheel.
There must be some way to uninstall, re-install the Syncmaster?
How can I resolve this?
Any help would be much appreciated. Thank you.

Aha, all is good.
I went to Library/ColorSync/Profiles/Displays
and to home/Library/ColorSync/Profiles/Displays
and deleted all SyncMaster.icc files. I did leave behind one SyncMaster file in the home/../Displays which had an old date and I new was ok.
Rebooted, plugged in SyncMaster, and a new icc file was automatically created in the /Library/../Displays folder.
My display works normally, now.

External Monitor for Macbook Pro (Use for Audio)

Hey
Well I have a Macbook Pro and am looking to get an extra monitor because I am an Audio Production major and need the space.
I'm looking for about 20-22 inch range and maybe one that swivels so it is horizontal or vertical.
Please let me know what you think.
Thanks
Ryan

Be very careful what you buy, and if at all possible test it with the computer before you buy it. A few times. These things just stop detecting external monitors for no reason sometimes, as well as just refusing to ever detect certain monitors.
Maybe someone here has a set-up that's working for them, that's your safest option.
