Hello Kaloka Kaloka,
Thanks for using Apple Support Communities.
From what I understand you're unable to connect to a specific external display, but your TV does function as an external display. Please follow the relevant instructions in the following article to troubleshoot this issue:

Connection to external display does not work under windows bootcamp, with a thunderbolt to vga adapter.

Hello guys, after searching a lot in the forum for an answer to this, I could not find a solution so this is the reason for this post.
I have a Macbook Pro (early 2011 I think) running MacOSX Lion and I have installed Windows 7 64-bit through bootcamp (version 4.0).
Everything works fine except that I cannot connect my external display through my thunderbolt-vga adapter.
The external monitor shows only the boot screen of windows (the one with the windows logo) and then, when I get into the login page it goes blank.
After reading the forum, I have done several things in order to fix this problem such as:
Restarting the macbook with the thunderbolt device connected to it.
Updated to the latest ATI drivers through bootcamp.
Removed the graphics driver and re-install it again.
I have tried to identify the external monitor through windows 'screen resolution' tool (attached photo).
but still no luck.
Does anyone have any idea on what else I could do in order to fix this? By the way, I find it very frustrating that Apple does not have a stable solution to the problem with devices that are connected to the thunderbolt port.
Thank you in advance

and here is the attached screenshot

Late 2010 MacBook Pro 15", upgraded to Lion on Sat 23rd no external display does not work

Hi all,
Wanted to ask this question here see if anyone might have a solution to my problem. I have a Late 2010 Macbook Pro 15" which I upgraded to Lion yesteray. Ever since that upgrade when I try to connect to my TV to watch a video no joy the image looks like the colours are out.
I have tried it on different resolutions and always the same. Then for some reason the MacBook Pro split the screen in two. So now I see the right of the screen on the left of the TV and the left on the righ with a big black line done the middle.
Priror to the Lion upgrade everything was fine. Only since Lion has this been a problem.
I am using a Minidisply to HDMI cable to go direct into my Phillips 42" Plasma, and I have not got a clue why this is doing this. The strange thing is it works ok on my Samsung BX2450 down the same cable no problems at all just the TV that has issues.
Any suggestions?
Cheers

Installed Premiere Pro CS4 but video display does not work?

I just got my copy of CS$. After installing Premiere I found two things that seem very wrong:
1) video display does not work, not even the little playback viewer next to improted film clips located on the project / sequence window. Audio works fine.
2) the UI is way too slow for my big beefy system.
My pc is a dual boot Vista-32 and XP system with 4GB of memory installed and nvidia geforce 280 graphics board with plenty of GPU power. The CS4 is installed on the Vista-32 partition. My windows XP partition on the same PC with Premiere CS2 works great and real fast.
Any ideas how to solve this CS4 install issue?

I would like to thank Dan, Hunt, and Haram:
The problem is now very clear to me. The problem only shows up with video footage imported into PP CS4 encoded with "MS Video 1" codec. So this seems to be a bug. The codec is very clearly called out and supported within various menues but video with this codec just will not play in any monitor or preview window. In addition the entire product looks horrible with respect to performance while PP CS4 trys its best to play the video. Audio will start playing after about 30 seconds. And once in awhile part of video shows up at the wrong magnification before blanking out again.
My suggestion to the Adobe team: fix the bug and add some sample footage to the next release so new installations can test their systems with known footage.
My PC is brand new with the following "beefy" components:

Mac Mini + A1038 Cinema Display does not work

Hi,
I have a 2009 model Mac Mini with mini-dvi and mini-display port's on the rear. I can connect any of my DVI based monitors to the mac mini using either the mini-dvi to dvi cable or the mini-displayport to dvi cable. All monitors except for the A1038 model Apple Cinema Display.
The cinema display works with 3 other computers with DVI ports, turns right on and is detected right away. When plugged into the mini it does nothing. Sometimes I can get it to work with the mini-dvi to dvi adapter but that is sporadic.
This is the same behavior with a 2009 model mac book pro and macbook. Using the mini-displayport to dvi cable the cinema display does not work but 3 other monitors do.
So my question is, why does apple hardware only work with non-apple hardware?

Is the A1038 the old, plastic Cinema Display that doesn't have a power cord or power supply? It only has a video cable with the special ADC on it? If that's the case, it needs this to run from a newer Mac:

My Ipad 2 external speakers does not work and headphones has popping sound. This all occured at the same time as my Iphone and Ipod headphones only played mono (no, the "mono" option is not on). How can there be audio issue for all these devices?

My IPad 2 external speaker does not work and the original headphones have popping sound when used. This all occurred at the same time as my IPhone and IPod headphones only plays mono (and no, the "mono" option is not on) with the original headphones, as well as, other headphones tested. How can there be audio issue for all these devices at the same time?
As you may have noted from the list of Apple devices I own, I believed in the Apple and the products it was producing; but it is hard to believe from my experience and the other voices within the Apple Community that we are all experiencing the same hardware issues. Especially since I recently, I upgraded to an IPhone 4g (no, my faith in IPhone 5 series is very little) and is experiencing the same audio problem as described above. So now, I am off to the Apple store again to be told that it’s a hardware problem on new IPhone. Really? Apple, what happen to the pride in the product you were producing?

Everyone does things a little differently. I love to "jam " along with iTunes ( or old Lp's) . Always have. That's where/how I've learned to play .
I'm sure leonieDF is giving a proper way to jam along on a keyboard with an iTune. He blows my mind all the time with what he knows. Nuff respects to him !
What I do is make a GB project I call "Jam With". I'll make several new tracks that are blank. Just has a few instruments named in the blank tracks. You can change those per song ...
Because I'm not concerned about changing the pitch / key.... of the iTune or the tempo ... I can simply play along with it.
Peace,
P. Dreadie

External editing does not work in LR4 (??)

external editing does not work in LR4 (updated from LR3 a few days ago)
has anyone an idea to solve this problem?
Thank you.

a friend of mine has the same problem - also updated from LR3 to LR4, external editor: elements 10
Which process version is the image you're trying to edit externally?
You right-click (I'm assuming PC, can't help Macs), there should be a context menu option "Edit in". You choose that, and there's an option for Elements 10 or not?
If so, what happens when you select it? Do you get any further message?
If not, you may have to go to Edit menu, preferences, External Editing tab and create a preset for Elements. In the "Additional External Editor" area, click "Choose" and navigate to wherever Elements is on your machine and you can create a new external editor.

Mapping Network Drive for external user does not work

I want to map a beehiveonline.oracle.com network drive. I am using https://beehiveonline.oracle.com/content/dav/# as mentioned in the FAQ.
Using https://beehiveonline.oracle.com/content/dav/ (without the #) does not work either.
I am able to map this network drive when using [email protected] as user.
However when trying to do this for the user [email protected] I am not able to map the drive.
I am testing this in order to simulate the client to map the network drive.
Logging on the beehiveonline with the user id [email protected] works fine.
Your help will be greatly appreciated.

Ah, We have had one other case of this where an account can access BeehiveOnline OK but cannot get the webDAV to work.
I did notice a few login failuers stating your account did not exist on the system. This can sometimes happen if there is a conflict between username and loginid - I have set them to be the same and this may help.
Try again and let me know how it goes.

17" LCD Cinema Display does not work on G4 Tower with ATI 9000

Hi,
I have a G4 Tower with the original AGP ATI Radeon 9000B video card. My friend gave me this unit just recently but not the original monitor. Well after he got his new 30" Cinema Display he gave me the original 17"LCD Cinema Display. I was so happy, plugged it into the card and fired up the CPU but nothing! just blank! It is not getting any power for the USB ports or anything. My buddy says the monitor was checked before I picked it up. I yanked the Video card out and put it back in, inside the CPU was clean as was the card, put it back together and still nothing. The VGA monitor I have is connected via adapter to the other input and works fine. I tried doing display settings and the Cinema is not even detected. Is the Video card fried on the digital side?
Do I need a new one?
Here is the info on the CPU:
Machine Model: Power Mac G4 (AGP graphics)
CPU Type: PowerPC G4 (2.9)
Number Of CPUs: 1
CPU Speed: 400 MHz
L2 Cache (per CPU): 1 MB
Memory: 1.5 GB
Bus Speed: 100 MHz
Boot ROM Version: 4.2.8f1
Serial Number: XB0120xxxxx
Any help wold be appreciated.

Hi MFG,
Welcome to the discussions.
The G4 AGP Graphics model originally shipped with an ATY Rage 128 graphics card. The ATI Radeon 9000 graphics card that is installed in your G4 is not the original card.
The ATI Radeon 9000 comes with a native ADC port (which you are trying to use). This port is only fully functional if the computer is ADC enabled. Your model of G4 is, unfortunately, not ADC enabled.
You can confirm this by opening the computer and having a look at the AGP slot (where the graphics card is installed). In ADC enabled Macs, there is an extra slot at one end of the AGP slot to accomodate an "extra leg" that the ADC graphics cards (such as the ATI 9000) have. This extra leg supplies the power and USB feed. You'll probably find this extra leg with no slot for it to go into.
What this means is that you are not getting power and USB feed through the ADC port to your display.
If you want to get the 17" ADC Apple LCD display working off this card (it's definitely the LCD display and not the CRT display, please confirm), you will need to use a DVI to ADC adaptor such as this one:
http://www.drbott.com/prod/db.lasso?code=0111-DVAD
and run it off the DVI output.
You can run your VGA screen at the same time (if you want to) off the ADC output by using this adaptor:
http://www.drbott.com/prod/db.lasso?code=0117-ADCV
This will work off the ADC port because, although the ADC port is not getting USB or power feed, it's still getting the DVI feed (which is what this adaptor needs).
Cheers!

External Display wil not work when I close my MacBook Pro

Help! I'm using a Vizio LCD with Bluetooth Keyboard and Mouse and I'm trying to use just the display with the MacBook Closed and Powered, but as soon as I do that the Screen on the VIzio dies. I worked for a while but now it won't work anymore. I can here the mouse and keyboard working but the screen on the Vizio will not display anything. bought a the only thing that I'm thinking is that i bought a cheap HDMI to DVI cable at Walmart..could that be the problem? Any feed back would be welcome. Thanks

6 With the computer turned on and your wireless keyboard or mouse paired, connect the other end of the adapter to the video output port on your MacBook Pro.
7 Once your computer's Desktop appears on the external display, close the MacBook Pro lid.
8 Once it's closed, wake the computer up by either clicking your Bluetooth mouse button or by pressing a key on your Bluetooth keyboard.
You mean it never wakes the external monitor at this point?

View images at 100% in photoshop on retina display does not work...

using photoshop:
I have a 15" new macbook retina display. If I want to view a photograph at 100% it does not 'size up'.
for example, If I open the same image on my desktop iMac, I see the image in all its 100% glory, so I can work on it in photoshop.
If I view 100% on retina display the image is tiny ( not 100% )
I never had this problem on my older macbook, so why is it happening and can it be fixed?
My first though was that because there are 'more' pixels, the image is 100% BUT looks smaller on screen for some reason due to pixel count...
Thank you in advance for any help!
cheers

Hi Nealeh
Thanks i think I got it working of a fashion.
Except the replace colour, does not seem to end up with the colour I picked using the picker tool. Its as though it hads not replaced the colour but blended in the desired colour with the old incorrect colour!
Buy trial and error picking not the right colour but close - which when mixed with the existing colour is close.
Sorry I can't post the pictures as the Lingerie Mfg, has me under non disclosure.
The scenario is:- say a blonded mainly tanned model a high cut [at the hips] corsette style basque, with an ultra low bra line.
Our dear model, has just come back from St Barts with a fabulous Tan, and equally striking bold Tan lines!.
So we have great tanned legs, then the 'porcelain white band' where her swimsuit was.
Likewise we have a tanned face, and arms, shoulders etc and a great tan on the top of the cleavage, then it stops, white band to the top of the ultralow cut bra line of the basque.
She must have lived in like the most conservative bikini on the planet [50's style], for 2 weeks!
Had she had a normal skimpy bikini on, no problem!
If i don't solve it, she will get fired!
Not a lack of interest in your post, but I was out, and tried to log in to this site; which I could do, on my iPad Air / 5 [whatever its the new one]. And tried to 'sign in' - but it just hung at the
"Join Adobe Community" adobe sign in splash screen! with he little whell spinning around continuously!!!
I have Safari on this iPad. Guess that is all it runs.
So technology is not my friend today!

Satellite L50-B-1P1 - external display is not working

I have just bought a satellite L50-B-1P1. When I tried to connect the RGB (VGA) port to a TV ( as a external monitor), the display screen of the laptop became smaller and the right part of the whole picture was missing, even when the external monitor was not switched on.
The laptop screen has left and right display a black background. The picture is located in the middle. Is this supposed to be normal or something is wrong with this laptop?
All answers are welcomed

As I understood the message, you have enabled the external display output and could see the picture on the TV.
The question is; what resolution the TV supported and what external output option did you choose?
The point is that you can switch to the external display choosing the option; extended desktop, clone display or you can switch off the internal display and show the picture only on external monitor TV.
In case you have cloned the display, both displays (internal + external) has to use the same resolution! In case the TV would support lower resolution, the internal notebook screen would lower the resolution too!
I would recommend you to read the user manual it provides some basic notebook knowledge

External camera does not work

My old iBook does not have any video camera for video calls. So I "bought" the following camera (Logitech QuickCam):
http://www.mymemory.co.uk/images/productshots/17101206530811.jpg
The camera came with a software which confirms that the camera should work with Apple. I also installed the software (successfully) in the harddisk.
However, when I clicked the QuickCam icon, I get an error message that the camera is not compatibe with my iBook.
Any views?

I don't see any mention of Mac compatibility on the product description for that item.
Also the Logitech support site does NOT have any downloads for the Mac OS.

Extended display does not work after downgrading to XP

Hi
I have downgraded from VISTA to XP
Before the downgrade extended display (19 LCD connected via docking) it was working OK
after the upgrade, it stopped working
I installed the latest video drivers from the LENOVO website, and tried playing with the FN+F7 but no luck.
It seems that there is some communication with the screen, as the screen looks as if it is working, but the entire screen is black!
when i look in the screen properties, it seems as if the extended screen is working, but again the screen is black.
any ideas?
thanks
Guy

which machine and what model of machine are we talking about here?? X60, X61??
