External display turned color negative mode

Hello, I upgraded to Leopard from Tiger and have been using my applications without much of a problem until today. I was away for few hours and my display suddenly started to show everything in color negative mode (blacks as white, green as magenta etc). Checked all no such option on preferences. I can not get out of it. Pls help. I was using Final Cut Express HD if that is relevant. The other user accounts in the computer are not affected. Thanks.

Press the Option, Command, Control, and 8 keys simultaneously, or turn off White on Black in the Seeing tab of the Universal Access pane of System Preferences.

Satellite A300-202 - External display turned a strange color

Hi,
I have a Satellite A300-202 with a ATI Mobility Radeon HD 3650, and after upgrade from vista to windows 7, my external display turned a strange color, seemed to lose the red color. Never show the white color, in which should show the white color shows the color blue.
I have uninstalled and installed again the graphic card drivers and update the new drivers but dont solved this trouble. My external monitor it's ok because I have tried with other laptop and don't have this trouble. I have also tried my laptop with other monitor and have the same trouble.
Anybody ever had this problem, someone who can help me?
Thanks,

Hi Xardas,
Yes I have problems only with the external monitor.
I tried both. Now I have the new beta version to the windows 7 64bits, downloaded from the amd/ati site, but I have tried also with the version available in the toshiba drivers page to my A300-202, and had the same problem.
Yes I have installed the new version of the BIOS too.
Thanks,

Can no longer use an external display in closed clamshell mode

Hi,
I have this weird problem that just started couple days ago.
I own a MacBook Pro Early 2011 since March.
It's always hooked up to an external display and the MacBook Pro's LCD is turned off (closed clamshell mode).
Lately, if the MacBook Pro's LCD is turned off, the external display won't show anything.
But as soon as I open the lid, the external display will then mirror the MacBook Pro LCD.
If I close back the lid, the external display will get blank.
I also tried to change the display settings with no luck.
In other words, I can no longer use my external display with the MacBook Pro in closed clamshell mode.
I'm wondering if someone experienced this problem before. Thanks for help.

Hello sebastieng
Open both, your MBP connected to the external screen. Open Preferences click here on "Displays" and then make the external Window to the main window by dragging the bar (line?) on top of the laptop window to the external window, which makes the second window the main window.

External display turns off when macbook isn't charging...

I have my old 2007 white Macbook hooked up to an external display. Recently I have been wanting to calibrate the battery while using it on the external display, but every time I remove the charger from the Macbook the external display will stay on for a couple of seconds then turn off, it will only come back on when I click the mouse or press something on the keyboard, but then it will go back to sleep. Note: when my Macbook is connected to the external display I keep the screen closed.

When you are looking at the displays in the System Prefs, all you have to do is click and drag the tiny rectangular bar from the main screen to the external monitor screen (this designates the primary monitor).
Once you've done that, all you have to do is close the lid. Your screen will flash a couple times, but the external monitor will then remain on and working, and you dont need to keep your lid open.
FYI, I would turn down the brightness of your MBP down all the way (for both the screen and keyboard). I have found that this reduces any heat build up that it may have from running with a closed lid.
Hope this helps!

External display orange color hue

No matter how I calibrate the colors my external display always has an orange hue.

Have you tried another display? If you did and it still does it, I would say you may have a hardware problem with your logic board. Try running your hardware tester once.

Not waking up with external display in closed clamshell mode.

Hello all!
I have the newest Macbook (late 2009), and have had it docked in a BookArc using an external display, keyboard and mouse. Everything has been working perfectly since I got it a couple months ago. I've traveled with the Macbook and redocked it at home a few times. This morning, I woke the computer and the display lit up as usual. A moment later, the display went black, said no signal and the power light went yellow (it's blue when operating). I hit the keyboard and clicked the mouse to wake it again to no avail. Took the Macbook out of the stand, opened the display and it works perfectly. Checked my energy saver settings, fine. Closed the clamshell, redocked, wont wake/start the external display. Took it out of the dock again, everything is fine, rebooted. Docked again, no wakey. I'm using it now as a normal laptop typing this. Any ideas as to suddenly why it wont wake/work with the external display? Thanks!

Last week I bought an Acer X223W 22 inch display for my MacBook (13-inch, Late 2009) – Model A1342 Polycarbonate Unibody and an Apple Keyboard MB110LL/A - Also using a Apple wireless Magic Mouse but not a BookArc. ( Just leaving on the desk next to the Acer display )
I've found that you have to have the MacBook connected to the AC Power Supply to keep the MacBook awake when trying to use an external display. It's kinda a pain sometimes, I usually boot up my MacBook before connecting the Display and Keyboard then once I'm logged in......
and Once everything is loaded I plug in the Keyboard first then The Display adapter cable, Close the MacBook up then Click/Move the Magic Mouse ( System Preferences settings - Bluetooth ( Advanced: Allow Bluetooth Devices To Wake This Computer - checked ) Energy Saver AC and Battery set to 3 hours ( All other settings Unchecked )
Sometimes takes a few clicks before the Desktop appears on the external display, Now once its on I can open the MacBook ( just enough to help keep it running cooler ) and unplug the AC Adapter unless it needs charging.

HT3131 External display in Closed Clamshell Mode

This worked for me until today. Now the display just goes off on my external monitor if I close the lid of my macbook. It doesnt re-appear as it says in the article. MacOS X 10.7.5

Congratulations on taking one more step in becoming more self sufficient in tech stuff.
But I have to wonder why you spent so much on a Retina display only to have it cooking uselessly there.

Display inverted colors / "negatives"

Hi I have a 20inch g5. today the display has inverted colors, black is now white etc. Does anyone have experience of or suggestions for what the remedy is? many thanks

Hi and thanks to Chris that's where the answer is. In fact after posting I googled it last night and found a forum that gave the answer in the fun way of saying hey ain't it cool to flip the colors on your mac like so.....there is a button to click or a group of three or four keys...and then I realised I had unknowingly caused this by dropping whatver on the keyboard and whatever landed on those keys. Freaky. I was worried about an apple repair bill but hurrah for the great advice on these forums (and elsewhere).

Not detecting external display after waking up MBP from sleep mode

I am a recent owner of a MBP and enjoying it. However, one problem that I can't seem to find a solution to is the external display problem after sleep mode.
When I first boot up the Mac and plug in my Dell external monitor via the mini adapter, there is no problem with detection or display. However, every time I put the MBP in sleep mode and then wake it up again, the external monitor does not "wake" up and my MBP only displays my normal screen on the Mac.
I tried to 'Detect Displays' to no avail and the only solution is unplugging the mini connection and plugging it back into the MBP for the MBP to re-detect the external monitor.
Although this is a quick fix in itself, I do not want to wear out the mini port by doing this every timeI come out of sleep mode. Any solutions so that the external monitor will detect the MBP waking up from sleep and display properly? Thanks!

And same problem here.
Using a MBP 2.66 i7 with a Dell 3008WFP that's connected to the MBP through DisplayPort. It works some of the time but once in a while (only been using the new MBP for a couple of days now) the monitor won't come out of sleep mode. Turning it off/on causes OS X to completely ignore the monitor. I was able to get this setup to work again by pressing 'Detect Displays' in the System Preferences pane but most of the times that doesn't help. The only sure way to get the monitor working again is by booting into Windows through Bootcamp, Windows is able to use the monitor, if I reboot after that OS X sees the monitor again.
Also saw a magenta line/stripe on the left side of my monitor and the monitor sometimes makes a buzzing sound when connected to the MBP through DisplayPort. That's what you get by using bleeding edge tech I guess :\ Only alternative is buying the mini-DP to dual-DVI connector but paying $99 just to be able to use an external monitor is rather insane. Besides that lots of users are having problems with this adapter.

MacBook Pro's Color LCD "shifts" when connected to external display?

I have a 2010 MacBook Pro with the hi-res anti-glare screen. I just noticed that the internal color LCD "shifts" its colors when I connect it to an external display (a Dell 2408 WFP). If I disconnect the external display, the colors internal color LCD go back to "normal".
I have two images to show what I mean:
This is what it looks like with the external display disconnected i.e. the MacBook Pro on its own: <http://www.flickr.com/photos/vazexqi/4558641163/sizes/l/>
This is what it looks like with the external display connected: <http://www.flickr.com/photos/vazexqi/4559271260/sizes/l/>
The wallpaper is from pixelgirlpresents.com. I didn't notice this problem before with my older 2006 Core Duo MacBook Pro (OS X 10.5.7).
My guess is that with the external display connected, somehow the color LCD decides to use the external display's profile as well (instead of its own).
Any ideas on why this is happening? And, more importantly, any ideas on how to fix this?
Thanks.
Nick

@Stefan: Thanks for the tip. I tried it but unfortunately it didn't solve the issue. The color is still off.
Incidentally, just out of curiosity, I tried these two things:
1) I tried the "Mirror Displays" option in the Displays Preference Pane. With this option enabled, both displays actually displayed the right colors (right with respect to how each display is calibrated).
2) I opened the same desktop wallpaper in Preview. Whenever I drag the Preview window so that it spans/crosses both displays (external and Color LCD), there is a light flicker in the wallpaper in the Preview Window. For that brief moment, I can see that the color is right before it changes to the shifted color on the Color LCD.
I found a possibly related thread on a different forum <http://arstechnica.com/civis/viewtopic.php?f=19&t=37841>. That doesn't seem to help when both displays are connected.
Now, I am just wondering if this is considered normal - wonky color shifts between the desktop/different windows happen when you have two displays connected....
Nick
PS: Note that I am not a graphics designer so my definition of right/wrong is just based on my experience looking at the wallpaper and remembering what it should look like on each display by itself.

Satellite U500 - picture on external display appears yellow

I use to attach the external display to my laptop to expand my desktop.
All of sudden one da the external display turned yellow.
I can still use the screen but everything on external screen is yellowish.
I connected my laptop with other screen with my laptop and its still yellow, then I tried to connect other laptop to my screen and it worked fine.
It looks like there is some problem with hardware, I have upgrade drives and did all I can do with software but still not done :(
Regards
Sagar

> I connected my laptop with other screen with my laptop and its still yellow, then I tried to connect other laptop to my screen and it worked fine.
This means that this issue is related to notebook and not to the external monitor.
I think it could be a graphic card related issue since the display driver update or new installation didnt change the situation.
So what to say; the GPU needs to be checked and in my eyes this is a job for a Toshiba notebook technicians.
What do you think?

How tow connect two external displays that are not mirrored and turn of the retina display

Hello,
I have two questions:
1. Is it possible to use two external displays either mirrored or not and turn off the retina display, and if so how it is done?
2. Is it possible to close the MBP and use an external keyboard while using two external displays?
I am using a music production DAW Persons Studio One-2 Pro and it would be great to be able to have this type of a setup.
Thank You,

Trying to run 2 external monitors, can't turn off clone mode

I have the 13" macbook pro running snow leopard, and recently bought two acer VGA monitors with a Matrox DualHead2Go. My problem: each monitor shows the same exact thing no matter what i do. I understand this is called "clone mode," and i can't seem to turn it off. I downloaded the driver for the matrox, and have tried a million different things to get clone mode to turn off. It seems like my computer only recognizes one monitor. When i try to arrange the displays under the preferences, it only shows only one external display. I have scoured the internet--no one else seems to have this exact problem. My guess is something's wrong with the dualhead2go, or maybe the one i have isn't the right one, or isn't for mac. Help please!
thanks,
hcm

If it's not too late to look at other products, you may want to check out Tritton's USB for multiple monitors. Before I switched from a PC, I had used Matrox Dual Head2Go with hit and miss luck. I then switched over to Tritton's product - it was a lot cheaper and worked better for me. When I switched to my MacBook Pro, I was able to continue to use the Tritton USB. I am currently running two monitors (VGA), plus my MacBook montor, for a total of three monitors. For my two VGA monitors, I am using a DVI to VGA plug, and the Tritton USB. It's been working great for me, and no problems with using extended desktop (as opposed to clone).
Good luck, and let me know if you have any folow-up questions.

W520 - now changes to "projector only" whenever display turns off in power save mode

I have my W520 in a dock with an external monitor. The display is configured to Extend - the external monitor is primary, and the desktop extends onto the W520 screen. I don't have a screen saver. I turn off the display after 30 minutes of inactivity. Until recently both the laptop and monitor screens would turn off after 30 minutes, and then both resume when I moved the mouse or pressed a key.
Recently, the system has started changing to "Projector Only" when the display turns off. After resuming from power save mode, only the external monitor activates, and the W520 screen is disabled. I have to use Fn-F6 to switch back to "Extend" to re-activate the laptop screen.
I have rebooted and re-saved the power plan.
Why has this happened, and how do I fix it?

Hi, timg11
I have a few questions so that I may gain a better grasp of this issue:
1) What is your machine type and model? You can find this information on the bottom of your machine. It should be in format XXXX-XXX.
2) What is your operating system?
3) Does this issue occur is the computer is not in the docking station? (Please try if you haven't already).
Thanks in advance,
Adam
