2010 MBP 13" and External Display

I have just purchased a new 2010, 13.3"MBP, 2,4GHz, C2D, 4GB RAM, 250GB Drive. Works well on/off power, after sleep, etc. No issues as at all. I plugged in an external HP1908w using an Apple Mini Display Port adapter [VGA]. I can use the system [plugged in] for about 20 minutes or so, then it just goes blank. The MBP goes black, and the external goes to a weird beige/pinkish screen.
I can't wake the system, or anything. I even tried unplugging the monitor, thinking it was a that. I plugged in the adapter only, no monitor, to see if it was that, and it works fine. No problems. I've run all the software updates, and everything. The only difference I see is that the resolution on the MBP is 1280x800, and the external goes to 1440x900. Other than that, I can't see what could be causing it? I've repaired permissions, did the PRAM, all that stuff...HELP!!!!

Take a look at this discussion (http://discussions.apple.com/thread.jspa?threadID=2439927). No solution, but I think you both have the same problem.

Trouble with MBP 15" and external display

ahh, the joy of a new display...
I just received my NEC 20wmgx2 (20" widescreen 1680x1050), a fantastic little monitor, with a little problem.
I cannot get this display to work properly with my macbook pro.
If I use DVI (DVI out to DVI in)
The external stays blank, and says no signal, the laptop display blinks, like it sees something is there, but even after clicking 'detect displays' nothing shows up.
If I use VGA (DVI->VGA adapter->VGA in)
Ok, now I have a picture, however the correct resolution is not on the list, all I have are typical non-widescreen resolutions.
Using third party software (switcresX) I am able to force the correct resolution option to get it to run at the right res.
However this is not an ideal solution by any means, and I would like to be able to run this monitor from dvi, no adapters, as I suspect that would be the best quality, and also avoid odd third party resolution hacks.
My question is then, does anyone have any idea why the macbook would not register the monitor correctly, or what I might try to do to get things on track?

I'm on looking for a solution, but I can only get my external Viewsonic working if I methodically unplug and replug in the monitor cord to the MBP 4-5 times. Try unplugging it (wait for the flash) and replugging it in (again - wait for the flash and a few more seconds for good luck) a few times.
I've been reading some posts about it not sending a signal to projectors and TVs properly. I think that may be it - it knows the external monitor is there, but isn't sending the external monitor enough signal to wake it up. Check your System Preferences -> Displays to see if it knows it's there.

Mid 2010 Macbook Pro sleep and external display problem

I recently upgraded to the new 2010 15 inch core i7 Macbook Pro. The problem i have is that it will not detect an external display (23inch Cinema) after waking from sleep. This happens after using the display to extend the desktop and also when using the Macbook in closed mode.
I've managed to get it to detect the display only after either restarting the Macbook completely or by going into energy saver and switching to dedicated graphics then going back to detect display.
It seems that when on integrated graphics it doesn't register that an external display is connected. If i leave a program open and running that causes the dedicated graphics to kick in then it works ok. If i close all programs, shut the macbook pros lid, computer sleeps and external display shuts off. If i click the mouse to wake with lid closed, apple logo lights, machine starts up few seconds later macbook returns to sleep. If i open the screen the machine wakes as normal but the external monitor doesn't.
Any help is much appreciated as its starting to frustrate me now...
Many thanks
oh and im running OSX 10.6.3

I thought it was intermittent to begin with until i started looking into it. By leaving programs open, like aperture, before i put the machine to sleep it appears to wake the external monitor up without a problem. If i shut all programs or leave basic things open like safari and mail which don't require the dedicated graphics, then upon wake it wont register an external screen is connected.
Manually detecting displays in settings doesn't work.
Disconnecting and reconnecting mini display port doesn't work.
Turning off power to cinema display and powering back up doesn't work.
To get the display going again its either 1) turn off macbook pro and re-boot or 2) re-start the machine then the display is automatically recognised. Or 3) launch a programme that kicks in dedicated graphics then manually go in and detect displays again..... like magic the display then springs to life.
No ideas anyone??

Different resolutions for Macbook Pro display and External display

Is it possible to have different resolutions for a Macbook Pro and an external display. I prefer to see less but larger on my Macbook Pro whilst seeing more but smaller on my external display. I use the DVI output to connect to an Acer 22in display.
Thanks in advance

I've actually tried that process and it doesn't work; I still get the same display qualities on both. Perhaps that process might work if one is not mirroring. Maybe there is a compatibility issue between my Macbook Pro and the Acer 223W. I'll persevere, but thanks for your help anyway.
Ian
Hi Ian,
allow me to chime in:
You are absolutely correct!
In 'Mirroring Mode' both internal and external display have the same resolution.
Only in 'Extended Mode' you can have different resolutions for both displays.

Lots of red dots on MBP 2010 internal and external display

Hi all,
Anyone's got any suggestions?
Over the last months there's been an increasing number of red dots all over the display (both MBP's own display and when connected to external display). The dots appear on different places (not static dead pixels) and especially where darker graphics appear (when playing games or just watching pictures or editing pictures, for instance). Especially playing games is impossible because of this graphics distortion. However, the degree of the problem varies.
Is this a hardware or software problem? I haven't had any problems with Apple hardware before.
Best,
Thomas

Thanks for the suggestions. I haven't had the opportunity to test on a different OS / boot, but I did try to change the energy saving settings as advised, but the problem persists.
Is it possible to attach an image file (screenshot of the issue) here?

Mbp not recognizing external display

I have a 2010 MBP 2.8 and I'm trying to connect to a 24" Samsung LCD display to use as a 2nd monitor.   I'm using the mini display to DVI. And plugging a DVI to HDMI cord to that.
When I plug it into the tv and computer. The screen on computer flashes blue a couple times then nothing happens.   The computer is not recognizing the display.    I'm running Mountian Lion obviously and theres no option in "Displays" in preferences.
Am I doing something wrong? I had a old Powerbook G4 that I did this with all the time with Leopard OS.    Whats changed?

Hey all, did a software update on my partner's mbp yesterday (10.5.8, security update 2009-006) and had the same thing happen where our external viewsonic display was no longer being detected. Plugging the cable in and out of the mini display port had the same effect already mentioned here where the mbp screen flashed blue like it was about to recognise the external display, but then nothing. Selecting detect displays from display preferences also had no effect. Tried resetting the PRAM and also the PMU, still nothing. So I shut down the mbp; disconnected the mini display cable; then turned off the viewsonic monitor at the power outlet and left it off for 10-20 seconds. Then I turned the viewsonic's power outlet back on, started up the mbp, turned the monitor on and plugged the mini display port cable in and the external display was back and working properly. Have shut down/restarted numerous times since then and it's all still working normally. Not quite sure how/why this busted in the first place, or why turning the viewsonic off at the power outlet seems to have fixed it, but it might be worth a shot for those experiencing similar problems... and it sure beats having to install/reinstall a different os version (which was going to be my next option)!

MacBook Pro and External Display on full resolution

I want to use only my external 20" cinema display, connected to my MBP. So what I do is connect the display via the DVI cable, close the lid of the notebook, wake it up from the keyboard/mouse (now I have the full resolution of the Cinema Display), open the lid so I can use the keyboard and the trackpad. This is all right with me, but when I restart or after sleep MacBook's display turns on and is set up as primary and the Cinema Display goes to Dual View mode. Is there a way the laptop to remember the external Display as primary, so I don't always have to close the lid, wake up the laptop and open the lid.
For instance, when I've done this for the first time in Windows, I didn't have to do it again. Now every time I log in in Windows, the macbook's display automatically turns off and the Cinema Display gets its full resolution. This is what i want to be done when I boot in Mac OS.

I know both scenarios (OS X/Windows), but I'm pretty sure that there's nothing you can do about it. As long as your internal display is open while waking from sleep or booting up, it will be always on in OS X. I'm only using my external Cinema Display and keep the MBP's lid closed all the time. Of course, I use an external keyboard and mouse as well. You can only choose which display has the menu bar on it, but you can't turn it off without sleeping the Mac. In Windows the ATi/Nvidia drivers take care of your settings, but it won't be applied until you get to the Desktop, so you'll still have the internal display on while booting Windows...

Lion and external display

Hi,
When I wake up my MacBoo Pro usingto work with external display, my laptop gets very hot and I with Snow Leo I was used to open the lid to cool it down.
It worked fine, because the laptop screen was black but with Lion I cannot do it because after opening the laptop lid I am getting immediately cloned desktop on my laptop.
Is it possible to come back to the previous behaviour or somehow to switch-off the laptop screen after opening the lid, still with keeping the external display as active and main one?

Hi tgr2007
According to Apple support, it is "expected behaviour" under Lion for the MBP's internal display to reactivate upon opening the lid. A new version of the clamshell mode-related knowledgebase article (replacing HT3131) is due shortly confirming this.
This is despite:
- the obvious temperature-related benefits that were previously achievable (under Snow Leopard) by opening your MBP lid whilst continuing to output solely to a 27" cinema display
- the complete and total waste of energy and graphics processing power in running two active screens if running your MBP in clamshell mode would otherwise make it too hot and/or noisy
- the negative longer-term impact on the battery and other components from running the MBP at any hotter a temperature than it needs to be.
If you would like to have the previous behaviour restored, please join us (ie the many customers who are being adversely affected by this change) in lobbying Apple to change how Lion handles clamshell mode.
Options available to Apple include changing Lion's expected behaviour or adding a user-selectable option within System Preferences.

2011 MBP freezing on external display in fullscreen

Hey all, had my 15" MBP for a few days now, and I'm experiencing a strange issue. When I have it connected to an external display and am playing a game (Starcraft II, EVE Online) or watching a video in fullscreen (Hulu, etc.) it will sometimes freeze and cause the computer to be completely unresponsive, forcing me to shut it down by holding the power button. However, audio will keep playing in the background. I'm using a miniDisplay port to VGA adapter and outputting to an HDTV. Ideas/comments/suggestions? I'm sure with using a new CPU and new GPU there are some driver issues to work out, just want to make sure it isn't more than that.

After doing some more tests of my own, I'm convinced that this is a driver issue. This kind of thing is common when a company releases a new GPU and CPU in the same model. (In this case the 6750M and Sandy Bridge i7) Correct me if I'm wrong, but each of you have either the top spec 15" or the 17" model, yes? By now, I guarantee Apple is aware of the issue, and I would expect to see a driver update by, if not before, 10.6.7 is released. Hold tight, my friends. Returning your computer or getting it replaced isn't going to fix this, and neither is complaining to Apple Tech Support (other than that it will make them more aware of the issue). The tech people you talk to have no direct interaction with the software engineers, and aren't going to be able to do anything. They may even recommend useless troubleshooting steps like an OS reinstall. I think we'll see resolution of this once they release a software update, and not before. I've given a link to this thread to a senior level tech advisor at AppleCare, so continue posting your reports here and they will be forwarded to the engineers. Being specific about situation, peripherals, programs, and timing will help them immensely, comments such as "THIS IS BROKEN, FIX IT" are less helpful. Cheers.

MBP not detecting external display

I encountered a strange problem today when I tried re-connecting my external monitor: it is not being detected by OS X.
I tried everything I could think of; I selected "detect displays" in preferences, I restarted the computer, I dis- and re-connected everything, I reset the PRAM, I tried connecting to a different monitor, and nothing seems to work. When I disconnect and reconnect the DVI cable, the laptop's screen flashes blue like it normally does, but nothing appears on the external monitor's screen. For the record I'm using the Dell 2209WA, and I haven't had any problems like this yet.
If anybody has any other suggestions as to what I should try doing, please let me know. Thanks!

MacBook Pro (2010) freezes when ejecting external display

Hi,
When I pull out the cable for my external display (connected via VGA>Mini display port) 90% of the time my computer hard locks and I have to hold down the power button to reboot. For some reason I'm still able move my mouse, but I can't interact with anything when it freezes. I've already re-installed the OS several times to no avail (I kept my personal files).
Mid-2010 MacBook Pro
OSX 10.8.2
2.4 Ghz Intel Core i5
8 GB 1067 MHz DDR3 (Kingston, 3rd party)
Also I have this problem where if I come out of sleep to the login screen and then don't click anything for a bit my screen will go pure white until I click/use the keyboard, which brings me back to the login screen. Not sure if related.
Thanks in advance for the help.

I also have this issue.
Macbook Pro Mid 2010 13"
2.4 GHz Intel Core 2 Duo
8 GB Crucial ram
Mac Os 10.8.2 (mountain lion)
Using Samsung 22" monitor with VGA to mini displayport as well
Usually it depends what I am doing but 30mins - 4 hrs I can expect my both of my screens to go grey (or sometimes flash green or purple) and totally unresponsive
Then I have to force shut down the laptop and boot up again. Rinse, repeat.
Tried the complete delete and reinstall of HD
SMC updates all done, but still happens
Anyone have any clues ?

15" MBP freezes w/ external display

I have an original 15" MBP. I usually use it with an external display (a 22" Envision LCD). Recently the MBP would freeze...a lot. I would still be able to use the mouse, however nothing else would respond and the only fix would be a hard reset. I've tried all the normal fixes (PRAM, etc..) with little success. The ONLY solid solution is to use it without the external display. When I use it just as a notebook it works perfectly fine. I had the same freezing issue when connected to a projector, so I don't think there's something wrong with my monitor.
Has anyone else had this problem..and if so, is there a fix?

I've had the same exact problem for months - good news - Here is Your Solution! - sorry for the long reply .....
I am a Mac User for more than 3 years. I got a new MBP on August 14th, 2006. I love it ! Recently started experiencing random problems with my MBP ( vintage - see above )
I have run my MBP in a dual monitor configuration while at home for as long as I have had the MBP ( about 3 years ) . I have never had any real problems until recently. IMPORTANTLY - the problem only happened while in using both screens - never if I was using the laptop in stand alone mode.
The problem - first a variety of colored horizontal lines would - apparently randomly appear on the screen. Next my MBP would suddenly freeze. The freeze almost always resulted in a hard restart in order to get going again.
The situation - after months searching the boards, talking to technicians, of trying various, tweaks and tunings and hours of frustration. The best anyone could come up with is that the video card or motherboard needed to be replace - " send it to apple " pay them 3, 4, 5 hundred dollars and they will send your computer back with a new board/ card.
The solution - As it turns out the problem was over heating and the solution was a little program - FREE - called smc fan control find it here -
http://www.eidac.de/?p=134 or here - http://www.versiontracker.com/dyn/moreinfo/macosx/31029
The best I can understand the sudden fan problem - there must have been a software controller change in one of the Apple updates - my guess to conserve power.
Just adjust your fan rpm's upwards. What I have found so long as I keep the internal temperature below 155 degrees F - everything is fine. Usually I am around 130 degrees F . The program has a handy temperature & RPM gauge that stays on screen.
It has worked like a charm and has solved all my problems.
Solution - update - I have since purchased a stand alone laptop cooling solution from Targus for about $35 USD. I did this to allow save my internal fans a bit.

MBP still thinks external display is connected when it's not

I have my MBP connected via DVI to an external LCD (HP w2007). Whenever I disconnect the DVI plug from my MBP, my MBP thinks the external monitor is still connected. I can go to Sysprefs > Displays > Gather Windows and it'll clearly have the HP's display pref window showing up.
This is a huge issue since any programs that were previously shown on the external display continue to think the display is still there and then I can't access them.

Had posted here because I figured the hold time for Apple support would be long because of Leopard's release. Hold times were not too bad. Problem is solved by resetting PRAM.

Problem with T400 and External Display....

I have a new T400 (less than 1 month old) with the shared memory Intel Graphics setup and I cannot get it to work with an external display of any kind.
I've tried 2 LCD panels (one widescreen, and one 4:3), 2 analog monitors, and a video projector without any luck. All of the displays I have tried work fine with my older Lenovo R61.
I've updated to the newest display drivers and tried working with the various settings under Graphics properties in Vista - Single Display (notebook, monitor), Intel Dual Display, Extended Desktop, etc. The best I got was a cloned image on the larger widescreen LCD panel that appeared for about 1 minute and then stopped. I recreated this 4 or 5 times, but the image would not stay on the external display.
Any ideas?
Thanks,

go into bios, check your video output option and whether you selected Internal + VGA, i think... i will check for you on my X60s....

Laptop Built In Display and External Display not Working

Hi all, I have a HP Envy M6-1158ca, and recently my Built-in display stopped working. I plugged it into an external display via HDMI and it showed no input. It seems as though the laptop is not booting into Windows either, as usually whenever my laptop boots into windows, the fingerprint scanner blinks letting me know I can now sign in using it. I am extremly frustrated with this, and have an unbelieveable amount of stress because this was my only PC. Please respond as soon as possible, it would be much appreciated.
Thanks in advance.
This question was solved.
View Solution.

Yes.. i think thats what might have damaged it...Notebook should always be completely powered off with the battery out and ac adapter disconnected while replacing any internal hardware..
Shouldnt be a BIOS problem....but still you can check this link..
Restoring the BIOS
Note:
If you have HP Support Assistant installed on the computer(The Blue Question Mark) then open it ==> Complete all pending Updates & Tuneups==> Restart and Check. It may solve your problem
