Trying to use and external monitor.

I am trying to use a regular external monitor to mirror my Macbook. My screen is broken so I cannot use it. I am using the Lion OS and have a thunderbolt to VGA adapter. I can get the starry pink and purple aurora background to come up but it does not prompt me for a login other than the background the screen is just blank?

It depends on the OS X version you have. If you upgraded OS X, I don't recommend you to use the DVD that came with your computer to reset the password.
Open  > About this Mac, and check which OS X version you have.
If it's 10.6 or older, you can use the DVD. Read "Resetting your original administrator account password" > http://support.apple.com/kb/HT1274
If it's 10.7 or 10.8, try resetting the password with your Apple ID following the steps of the link above. If it doesn't work, reset the password through Terminal and Recovery > http://discussions.apple.com/docs/DOC-4101

I've got a MacBook pro 15' running 10.6.6. I want to use an external monitor for my graphic design work running Adobe software and thought I'd try an HD TV. I ran a Mini Display to HDMI lead to the TV but the picture quality was disappointing.

I've got a MacBook Pro 15' running 10.6.6. I want to use an external monitor for my graphic design work using Adobe software and thought I'd try an HD TV. I ran a Mini Display to HDMI lead to the TV but the picture quality was disappointing. I also tried a Mini Display to VGA lead and that wasn't much better. I tried all variations of resolutions in System prefs - Displays but nothing helped. Am I getting something wrong? Thanks all.

In addition to pixel density, you are up against the translation driver card in the TV.
If you read the fine print of computer-resolution-capability in the TV user guide, you will see a chart as tall as the manual page. At the top is the smallest resolution capable, at the bottom is the full use of the 1080p in the TV.
Mac falls into the top 25% of the page, maxing out at 1366x768 often. This is because the TV control card is expected to do too much of the work, but is not designed for computer-monitor processing.
I looked at the resolution charts on 2 TVs before deciding to buy a 1080p LCD monitor that has a TV interface/connector. Computer monitor first, TV second. But the thing is only 27 in. Good thing TV is not as important to me as it is to others.

I am trying to use an external 3g modem made by Huawei model e173s-6 and when I do connect it on my usb port the macbook pro just do not recognize it. I own a 2012 model with mountain lion 10.8.2 . What should I do ?

I still don't know what happened to my test Aperture Library after the update to 3.4...Not only were my previews lost, but so were the original images! Needless to say, I haven't bothered to update the main library on the Mac Pro because I don't want to deal with this level of uncertainty (even with backups in place).

When I close my laptop lid and it goes to sleep so that I can use an external monitor, monitor does not turn on when I hit a key to start laptop

When I use my external monitor, I cannot get it to work after awakening my laptop using any key. My monitor won't light up although laptop keyboard is backlit showing that it has come out of sleep mode. Why does the monitor not get the signal from the laptop?

I still cannot figure out why it doesn't always work. All parameters were met and my bluetooth keyboard is set correctly to wake the computer. My keyboard becomes backlit, but my LG monitor does not pick up a video signal and is black and my laptop monitor is off. The only way I can get out is to hold on button on laptop until it shuts down and I can start up again. This happens on an intermittent basis. Sometimes it works and other times I get black screens. I need to know if I can use command F1 to get the laptop to detect the display or is their another key combination to send the signal to the external monitor when I can't see anything because I hate to do a hard shut down to get out of this mode! Please advise!

Why does my screen turn blue and freeze every time i try to plug in my 'mini display to hdmi' cable into my thunderbolt port in order to use an external monitor?

why does my screen turn blue and freeze every time i try to plug in my 'mini display to hdmi' cable into my thunderbolt port in order to use an external monitor? it only works if i turn the computer on with it already plugged in.

Do you have gfxCardStatus installed? Is your monitor set to "Integrated" or "Discrete". You want it set to Discrete to drive the external HDMI display.
Try resetting the PRAM and SMC
<About NVRAM and PRAM>
<Intel-based Macs: Resetting the System Management Controller (SMC)>
Are you sure you have a good miniDisplayPort to HDMI cable?
Do you have another HDMI display you can test against (your neighbor's HDMI capable TV).
Do you have friend that can test the cable using their Mac and maybe their TV or a monitor that has HDMI input.

Using an external monitor with the computer closed and using a bluetooth ke

Yea i do this all the time on my big screen I just go in to system preferences and bluetooth and tell it to allow devices to wake the computer and then close the desplay then wake it with mouse or keyboard.

Macbook Pro - Black screen and external monitor

Hi there,
I'm new here and it would be great if anybody could give me some advice about my Macbook Pro issue. First of all, I would like to thank all the contributors for your comments. I'll go to an Apple Store asap, but I'll really appreciate any of your comments so I'll know more about this issue and how to manage it.
My device details are:
Macbook Pro / 2.8 GHz Intel Core i7 / 4GB 1067 MHz DDR3 / Macintosh HD / Mac OS X 10.6.8
NVIDIA GeForce GT 330M
Other connected equipment:
HP Monitor Pavilion 22xi (with an official Apple adapter - projector's plug)
Wacom tablet Bamboo Fun (USB connection)
I usually work with graphics software (Illustrator, Photoshop, etc.), since I bought my laptop (3-4 years ago) it has worked faultlessly. But I started to notice some problems about two weeks ago. The problem is basically always the same: After some hours of work, suddenly and randomly (it tends to happen when I click on a button) the screen turns off but the computer is still running (I can hear the fan and hard disk). As I said I use an external monitor, and it also turns off at the same time. That's why I thought it may not be a problem with the screen, it's probably related to the graphics card ?¿?
The troubleshooting steps that I've tried are:
After waiting several minutes and without any response, I have to restart my laptop. When it turns on a Panic Report message pops up. It says that a severe problem made me turn the laptop off suddenly (or something like that). The Panic Report says something about "kernel_task", I have no idea what it is, just in case it could help to clarify more (I've printed all these panic reports).
I also have to mention that this laptop gets really hot on the left side, which I reckon it's a very common thing in these devices. I have to use a desktop electric fan to provide relief to both of us
I've also disable the "Automatic graphics switching" tab in Energy Saver menu.
Despite all of this, the screen and the external monitor are still turning off.
Any idea?
Thanks a lot,
Clara

I would suggest that you run AHT using Using Apple Hardware Test. You can either reboot the machine and press the D key, or use your second Grey disk. This would potentially show you any HW problems.
Typically these older machines exhibit GPU issues. There is a third-party application called gfxCardStatus, that can provide some insight as well.
This may or may not help if there are GPU issues - About NVRAM and PRAM (reset NVRAM/PRAM/SMC).
It is possible to enable remote access (via SSH) and even if the screen is not working, the machine can be accessed remotely. Please see System Preferences -> Sharing.
Can you run a test with both the lid of the MBP and the external monitor plugged in. Does your external monitor disconnect, but the internal one still show a screen?

Can I use an external monitor in portrait mode?

I do not yet own a Mac, but I am doing up-front research to know what to expect.
I currently have a Samsung 204T LCD monitor (DVI) which allows rotating the display into portrait mode.
I know that OS X supports using an external monitor to extend or mirror the desktop. Can an external monitor be configured for operating in portrait mode? I would expect that this requires the video driver to rotate the display before sending it to the monitor.

I will leave this answer to my original question.
I called Apple and was completely disappointed with their answer. They indicated that they would not answer such a question, since they deemed it to be "outside of the scope of Apple support" since my question was deemed "not a consumer-oriented
question."
So yesterday, I took my Samsung SyncMaster 204T monitor to the local Apple retailer to try it out on an actual system. I specifically tried it out on the 24" iMac with the nVidia 7300GT graphics card, since that is the system I was interested in.
It turned out that this monitor works beautifully in portrait mode with the above system using Tiger 10.4.8.
So, I went and bought it!!

Use two external monitors

Hi Guys!
I am using a MacBook Pro early (2011), i also use an external Monitor. (Works fine -> mini displayport dvi adapter) !
Yesterday, i tried to connect an older (VGA, i did not want to throw it away) monitor too, in order to use 2 Monitors + MacBookPro-Monitor!
Is there a way to use these two external monitors?
Thanx guys for your help, if this topic was discussed in the past, i apologize for this extra entry (May you can show its link)

Can't seem to get DVI and external monitors to work (works on windows) ?

I'm going crazy here and I'm starting to think something is broken/wrong with the mbp I just purchased (I'm hoping it's just me and not the mbp)...
I have a BenQ FP91G+ LCD monitor that works fine using dvi with my windowsXP machine. When I try to get this monitor to work using DVI with my mbp all I can get is a black screen. The mbp sees the monitor fine since I can see it in the display settings. I've tried every different resolution available in the display options (with mirroring off and then again with mirroring on). No luck with dvi. However, if I use the vga cable with the dvi adapter things are fine.
I then tried two other lcd external monitors with the dvi input (one a Princeton model here at home, and a different model that I tried in a Best Buy - I think it was a sycmaster). The Princeton at home had the same BenQ problem - just a black screen no matter what I tried. The one in best buy, however, got a 'bit' further when I set its resolution to 800x600 - but even then it was bad since the display was just scrolling vertically.
I'm a bit stumped what is going on. I really should be able have this digital output work since all three of these monitors work fine with the dvi cable on windows.
Is there something seriously wrong with my mbp? What else should I try? Thanks for any help. (I've been searching these forums but haven't found anything yet to help.)

Thanks iVmichael, that makes me feel a little better at least. I'm guessing maybe the issues I'm having might be driver related? Seems odd that all 3 monitors I would have a problem with, but I guess it's possible. I can deal with the dvi-vga adapter usage, just don't want to something to be wrong with the hardware on the mbp.

Trying to run 2 external monitors with HDMI splitter

I'm trying to run two external monitors from my iMac using an HDMI splitter but I can only get signal to one. I've read a lot of forums saying it is not possible to run two monitors from an iMac but the two monitors can be mirrored, in fact, I would be prefer it if they were.
I've got the mini-DVI to HDMI cable running to an HDMI splitter, one end going to my 52'' Sharp Aquos tv and the other to my 21" BenQ monitor in the kitchen.
I would just like to be able to have both monitors playing the same video at the sametime, I don't understand why this would not be possible.
I'm at work so I don't have the exact specifications but I recently purchased my iMac and have the i7 processor and the Radeon 5750 graphics card so I know it's not a hardware limitation
What am I doing wrong?

I will reply to my own question just because I figured out the answer.
The Larger display has to be set to the maximum settings of the smaller display
For example: My sharp aquos has to be set to 720p BEFORE plugging in the BenQ which will not do 1080p
If you try to plug in the benQ before setting the Aquos to 720p, it will not work and you will not be able to change it after the fact.
May seem simple now, but boy did that drive me crazy for a while.

How do I use an external monitor with my MacBook??

Hi,
I recently purchased my MacBook, but when I am at home, I want to be able to use my MacBook like a normal computer, by plugging a keyboard, mouse and my existing LCD monitor to it.
What do I need to purchase to enable this and what system settings do I need to adjust to get my monitor to work?
Could I have my laptop closed while i am using my external monitor? How do I do this? I don't want my MacBook open, while I am using my monitor!! Can someone please give me a simple step by step guide on how to turn on and use my laptop which my external monitor plugged in.
Thank you very much for your help.

Can you read it ? http://discussions.apple.com/thread.jspa?messageID=3510076&#3510076
Shortly,yes,if your Display connected,just close it and than click the mouse it'll wake up in external display.

How do I use two external monitors with my laptop?

I have a new Pavilion dm4-301 d cl Entertainment PC. My OS is Windows 7. I am used to using two external monitors with a docking station. This new laptop does not have a docking station. What do I need to get to use two external monitors?
This question was solved.
View Solution.

Certainly not without a dock but even with, HP laptop docks pretty well limit you to one of the external monitor ports, even if there are two on the dock. We have used a device called an Atlona AT-HDPIX2 which is a usb to hdmi adapter. It provides a third monitor capability for a laptop....use the native external monitor port and the internal laptop display and then this device gives a third monitor which is full configurable from the Windows 7 display interface...clone, extend, etc. It allows full HD resolution and is responsive enough for even light gaming. HP makes no true docking station for your laptop.

Is it possible to use 2 external monitors?

Hi,
My name is Joe Chaplow, and I am new to the forum. Hello all.
I want to set my Macbook Pro 15inch Mid 2009 model (2.8ghz with 512 dedicated vid ram and 256 for power saver mode) up so that I use two external monitors. I want to mirror the desktop (so I can slide programs from one screen to the other). If i use the mini dvi to dvi adapter and split the adapter, would this work? Thanks in advance.

No, splitting won't work. You will find a discussion about the use of USB adaptors to use multiple monitors here. Here is another article.
Matrox makes a special adaptor for adding multiple monitors to laptops.

Satellite A100-646 and external monitor shows black screen

Hello to everybody,
I have a similar problem with A100-646 (bought in Italy). Laptop's LCD and external monitor shows black screen but system boots without other problem. When laptop is not used for a long time (half a year) it work for one week without any problem.
Unfortunately, there is no proper service in a place where I live. Perhaps, there is a problem with power supply.
Is there other idea? Does anybody have a service manual? ([email protected])

It is not easy to find shop where you can order original and new hardware components.
Best source for such parts is definitely eBay where you can buy used but well working components.
Upgrade? You must know that upgrade on mobile computers is not the same as on desktops. Cooling possibilities are not the best and each notebook model has optimized cooling system for original parts. So new graphic card can be more powerful and produce more heat and it is definitely not good for your notebook. So best thing you can do is to replace it with original part.
