External "Dual" Monitor not recognised (PowerBook)

Using Leopard my PowerBook no longer recognises an external monitor (Dell 17"")
Behaviour is as follows - Plug in the monitor, slight screen flicker to blue then returns to normal desktop
When booting off a Tiger partition (to enable access old Mac OS9 apps) the external monitor works OK
I antisipated 10.5.1 would fix it but it didn't ...
Any ideas ?
Thanks

I agree with you, to display the output on the second output can be done with the FN+5 keys. I am extending my desktop to the second graphics port so that programms such as powerpoint can "Display on second monitor" whilst opperating from the primary screen. The problem is that in order for the second port to be recognised by windows it has to have a monitor plugged in to it, but I have only got a SVGA to Composite video frame converter & the laptop dosen't recognise it as being a valid monitor.

Satellite A30: Dual Monitor not recognised by windows

I feed the second monitor output from my Satellite A30 to a frame converter for generating a composite video signal. In order for windows to enable the second monitor output on the laptop I have to have either a monitor or a projector attached. Is there a simple way of providing a 'dummy' device to trick the laptop into thinking it has a second monitor and removing the need carry extra kit around.

Sound from computer nolonger goes out through HDMI cord. Picture does. How can I fix this?

I have a HP Pavilion dm4 entertainment laptop with Intel core i5 m430 2.27GHz. Just recently - when I plug in an HDMI cable connected to the TV - the sound does not go to the TV. Previously it did. How can I determine what has changed to prevent this from happening?

Sorry - I meant dm4. Thank you for responding so promptly. Since I originally submitted I found the solution. I couldn't get it to change from the default laptop speakers in the sound mixer in the taskbar but when I went to the sound settings in the control panel with the hdmi plugged in and made the samsung TV the default speaker it went to the TV. I thought I had tried this before but in any case this time it worked. Again - I thank you for responding so quickly. Next time I may really need the aswer quickly.

Sony Bravia Z5500 will not recognise HDMI output from Apple TV 2nd Gen

After a frustrating time trying every connection possibility - various HDMI cables, all 4 slots, I still had no picture or sound. A week later (living so far from the shop) - I( angrily confronted stafff and told them I had a dud Apple TV. I had spent hours on the phone, firefox, apple and sony sites.
They took it from me and plugged it into a samsung 3d tv and - hey presto - instant picture. I feel like an idiot - and I thought I knew all about technical issues. But this is just annoying me. They looked at this old man and just shook their heads. I am resorting to the hope that someone out there knows the answer ... ??

got a bravia KDL-40WE5W and my appletv 1g never had any problems but if you messed with hdmi settings if thats possible and forced it to use various overscan only accept 1080p or something that could cause problems I guess

Lenovo B570 isn't recognizing a monitor through a HDMI connection.

The title says it all really, every time I connect my B570 to my Benq monitor using a HDMI to DVI cable, the laptop fails to detect anything.
When I connect the laptop and screen using the VGA to VGA cable, the laptop picks up the screen without any trouble at all. I bought a new HDMI to DVI cable and the laptop is still failing to recognise the monitor.

hi flytch
can you check if the cable works first? (you can use another computer to check it if you have)

I have a late 2008 white macbook. I have a mini dvi to hdmi adapter, and a hdmi cord. My cannot get my MB to detect an external monitor. Nothing happens when plugged in. Also, my display settings does not have an option for mirroring or arrangment tab

Yeah, I'm having the same exact problem - It seems that the thunderbolt minidisplay port is only able to output the analog VGA signal, not the digital signal to support DVI and HDMI. This is a bug that came up after installing 10.7.1. I bought my macbook air with 10.7 on it, upgraded it to 10.7.1 as soon as I got it, so I have never been able to use hdmi or dvi with my macbook air. This is an extremely frustrating problem for me, I used HDMI on a daily basis with my PC. I have spent many hours at the genius bar running diagnostic tests so Apple can get as much information as possible to create a fix for this problem. I have been emailing tech support for 3 or so weeks now, they keep saying that they are working on a fix and it should be out soon, but 10.7.2 has come and gone and I still have no HDMI functionality with my MacBook Air!

Mac Mini Newbie + Viewsonic VX2450WM monitor. Need HDMI to DVI adapter? What cords needed?

Mac Mini Newbie here.
Getting the Viewsonic VX2450WM monitor for it. There is no HDMI on this monitor, but reviews said it's Mac mini compatible.
Do I need to get an additional cord? HDMI to DVI adapter cable? Does the supplied short white cord inside Mac Mini packaging suffice?
Thank you!

No, the HDMI on Mini only support digital VGA is analogue
Can the HDMI port drive analog displays (VGA displays for example) using adapters?
No. The HDMI port will drive digital connections—such as DVI—using the adapter that came with the Mac mini, but cannot be used for analog displays such as VGA. You can purchase a Mini DisplayPort to VGA adapter separately to drive analog displays.

I just bought the new HDMI cord for the IPad, it works good but a small potion of the TOP and the BOTTOM is cut off. It doesn't seem to do it for movies. My monitor is a 23 IN' acer s series.

My monitor is a 23 IN' acer s series. I just installed the drivers for my monitor with no change. I think I have a CD somewhere for my monitor maybe it has some kind of program in there that can help me. I can post a picture if I need to. Thanks

No work around that I know of.

Hdmi cord suddenly incompatible. Won't display picture.

I use a Hdmi cord to stream movies through my iPod touch to my Tv. It worked great until I upgraded to iOS 5.0. Then, it is suddenly 'not supported by iPod touch'. It plays audio, charges the battery, but wont display a picture on screen. What happened?!

Did you try to reset the iPod by holding the sleep and home button for about 10sec, until the Apple logo comes back again?
If this does not help, try to set it up as new device:

My AppleTV stopped working after power outage. Light is on and I rebooted and reset w remote but it keeps giving me a pic of the Hdmi cord like it is not recognizing the hdmi as being plugged in. I've unplugged it several times.

It is in recovery mode. The picture is telling you to connect to iTunes via micro usb cable in order to restore.

Macbook pro(2008 later) can not recognise external monitor(NEC UXI2090) with mini-DP to DVI adapter with 9600GT

I bought mini-DP to DVI frome Apple several monthes ago and it worked well in that time until yesterday the external monitor show me no signal sign. Other PCs were connected with the same cable and monitor and they are fine. I am wondering there is something wrong in the adaptor or macbook pro. Furthermore I found the external monitor can display nornally when I switched to 9400 graphic card and used mini-DP to VGA adapter. If I switch to 9600GT no signal again. If I switch 9400 using mini-DVI, it is shown on the external screening: Out of range... In a word, In the mode of 9600GT, mac can not recognise external monitor(I can not detect it in the systerm preference even I press detect display buttun) and 9400 works in VGA mode. However when I connect adapter to mac, the screen showed blue flash.
I reseted SMC, no use; I created a new account or enter mac to safe mode, no use; so far I did not reseted PRAM beacuse of something wrong of my system. I am downlaoding Mountain Lion OS and will install it. Then I will reset PRAM and try again.
I do not know whether I shoud change the adapter or the single-link DVI cable to dual-link. Someone said it is useful in their condition. I tried some methods from BBS, such as connected when devices were off and then open, and so on. I failed.
Any suggestion for this problem?
Addition: OS: 10.7.4(Lion)

I turns out that the logic board of my MacBook Pro was faulty (despite being brand new).
I took it to the Apple Store, presented the problem, and one of the Tech's came to the same conclusion that I had -- hardware failure. Phone support was no help in the matter (and even told me that what I was trying to do wasn't a supported option, which is rediculous). However, the Genius Bar did take care of the problem, and my MacBook Pro was back to me with a replaced logic board within a few days.
Hope that htis helps.

Error 1604
This error is often related to USB timing. Try changing USB ports, using a different dock connector to USB cable, and other available USB troubleshooting steps (troubleshooting USB connections. If you are using a dock, bypass it and connect directly to the white Apple USB dock connector cable. If the issue persists on a known-good computer, the device may need service.
If the issue is not resolved by USB isolation troubleshooting, and another computer is not available, try these steps to resolve the issue:
Connect the device to iTunes, confirm that the device is in Recovery Mode. If it's not in Recovery Mode,put it into Recovery Mode.
Restore and wait for the error.
When prompted, click OK.
Close and reopen iTunes while the device remains connected.
The device should now be recognized in Recovery Mode again.
Try to restore again.
If the steps above do not resolve the issue, try restoring using a known-good USB cable, computer, and network connection.
