Mini dvi issues

My mini dvi worked perfectly until today. Monitor no detected, and no signal on the monitor ( wich work perfectly with my ps3 and on another computer). I found someone with the same problem here but no reply since 2009
I try on windows ( bootcamp) it doesnt work...
thx

I have this problem too. What I have found is that if the vga adpter is connectto a monitor, I can get a signal from the HDMI-DVI adapter. But when I disconnect the vga adapter, the HDMI-DVI signal goes away too. Anybody know what's going on here?

Lion 10.8.5 - HDMI over mini dvi issue

since updating my conputer from 10.8.4 to 10.8.5 - my notebook does no longer detect my sony tv or my new computer screen (work fine with VGA cable) did an update with 10.8.5 combo - same problem - cables are working fine on others computers - i do not have a backup with .4 on it so that not even an option to do a restore - pleaese help this is relly anoyinng - it apple beconming like microsoft?

Hi Jaws1431,
I am in the same situation as yours. I ordered a Mini-DVI to HDMI (cheap) adapter to connect my two MacBook to a HDTV.
The first MacBook, under Mountain Lion 10.8.5, isn't working even with all the tips around the net. I haven't tried it under 10.8.4 however.
The other one, under Snow Leopard 10.6.8, is fully working.
Since I want to use the first one with a TV, I'm in trouble.
Two things to do :
- Try with a genuine adapter (if you're in the same situation as mine, aka cheap $3 adapter);
- Try updating to Mavericks (haven't done it myself yet), or go back to Snow Leopard.
I'll let you know when I applied any of those solutions.

Mini-DVI to video adaptor tv connection issues

Could it possibly be with the new software upgrade? I just updated from 10.6.1 to 10.6.2 and all of a sudden my Mini-Dvi to Video stopped working. I'm using my Mini-DVI to VGA without problems at work with the same computer and a few minor adjustments to the display prefs.
Apple says the 10.6.2 update was supposed to correct display issues. Could they have accidentally deleted support for the adaptor while correcting other issues?
Perhaps the cheapest solution to this would be to downgrade back to 10.6. Any advice on this?
I'm running a 2.2 Core2 Duo MacBook from mid-`08.
I also found this article on PCstats http://www.pcstats.com/articleview.cfm?articleid=2147&page=3 that says the GMA X3100 chips do have integrated graphics for analog, s-video etc... so I'm guessing that somebody may have accidentally deactivated the analog features of the chip while writing the graphics update. Only my guess I'm not a programmer.

With your TV hooked up to your Macbook, you should be able to view anything on your computer. If you have all of your pictures in iPhoto, your best option is to use FrontRow by using the remote.

I have an HDMI to mini DVI cable issue!

Recently my cable i use for my TV stopped working and i can't sort out why. when connected, my computer goes blank (black) and yet if a video is playing i can hear it. problem is i cant seem to get out of the black screen even if i disconnect from the TV. i have to shut down the computer manually because it seems to be stuck. what could it be??? bad cable? bad port? i do not leave my computer connected all the time, so could it be plugging and unplugging the cable from the computer? it worked simply for the longest time so i can't imagine what happened. i heard maybe a mini DVI/HDMI adapter on my computer might be a good idea too. please advise.

Hi hayesjdr78,
Thanks for visiting Apple Support Communities.
If you no longer see video when connecting your Mac to your TV, try these steps first:
Check connections
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the systemYou can reset the Mac's parameter RAM and SMC.Reset the resolutionStart by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.

Mini DVi to VGA colour issues

Hi,
I recently purchased a projector to connect to my macbook. My intension was to use a mini-dvi to vga cable to do this, however when i connected everything up the projected image had a green tint. I must also state that i have connected a TV to the same port with a mini-dvi to s-video adaptor with no problems with the colour.
My first thought was that the cable was the problem, so i borrowed my friends macbook to see if they had the same problem. There where no issues, so if figured it was either a software or hardware issue.
My next step was to boot off the start up disk and plug the projector in, same issue - green tint.
So i have concluded that it is a hardware issue. I know that the mini-dvi port is connected directly to the logic board, if i want to get this fixed will i have to replace the whole logic board or is there another way.
All your help comes much appreciated.
Thanks in advance
Bob

Hi DoDolom,
First, welcome to Macintosh!
Secondly, it sounds to me like what's happened is that OS X has extended your desktop onto a second monitor. Plug in an external mouse and keyboard and then close the MacBook's lid. It will go to sleep. Use the external mouse/keyboard to wake it up and you should be running on just the external display.

Mini DVI to TV flickering issue

I have 3 different Mini DVI dongles - one to S-video, one to VGA, and one to DVI. All are apple branded.
It's been a while since I last used the first two - the DVI one is brand new.
I recently purchased a 1080p TV to use as a second monitor. When connected using any of these dongles, the picture on the TV flicker's intermitintley. I've tried using different video cables with each dongle and have tried hooking the MacBook up to another TV. The same issue every time.
It's an early 2008 white MacBook. I'm starting to believe the Mini DVI port is faulty. What are my options here to fix this? The computer will be replaced at some point this year, so anything over a $100-$200 repair is probably out of the question. Any suggestions?
Thanks.

If you go into Display preferences, is 1280 x 800 a selection option? If yes, what happens when you select it?

Mini DisplayPort to DVI issues

I just recently purchased the new aluminum MacBook, having previously owned one of the very last iterations of the white MacBooks.
With my old white MacBook I had purchased a Mini-DVI to DVI adapter, and was using that to connect to a DVI to HDMI cable, and that cable was going into my HDTV. I would select and check Overscan under the Display Options of my HDTV, which appeared as PDP-xx50SX under my MacBook, and two black bands would be added to the top and bottom of my MacBook's display, and I would get a full screen crisp image on my HDTV that I was very satisfied with, I would use this to view TV Shows and Movies on Hulu without any issues.
I no longer have that MacBook as a few days ago I got my new aluminum MacBook, and with it my Mini DisplayPort to DVI adapter. 4 hours ago I wanted to catch up on The Office, so I plugged in my new adapter to the Mini DisplayPort, hooked up my DVI to HDMI cable, and that into my TV, just like I did with my previous MacBook. That was 4 hours ago, and I am still unable to properly configure it like my last MacBook.
I have been beating my head for 4 hours now looking across every forum on the internet, every thread, and every possible way to type out this issue on Google to find any and all results. For some reason I just do not get the Options tab like I was able to on my old MacBook where I could then select the Overscan checkbox.
This is really frustrating, I've tried every possible combination of resolution, mirrored and not, and nothing works like it did with my old MacBook. I simply cannot get a correct full screen image on my HDTV.
Is this a firmware issue? Has it already been addressed and I somehow missed it? Is there any fix? Is this the cause of DisplayPort? Why wouldn't nVidia's 9400m be able to do the same thing Intel's GMA X3100 did? So many questions, and I didn't know where to turn to so I came here to the Apple Support forums hoping I'd get some resolution or reassurance this is something that will be/is being addressed. The only fixes I've seen online are programs like SwitchResX or DisplayConfigX, but I'm not that technically savvy and would rather not fry my screen, especially when it worked perfectly out of the box with my older MacBook. Help!

I am also frustrated by the new display port. I have purchased a DisPort to DVI connector from the Apple store and the pin configuration is different than previous all other Apple adapters (DVI-I). The 4-ins around the blade are missing in the new adapter. The genius bar said in Orlando that the new adapters are a new version of DVI called DVI-D. So all my previous investment cabling is hosed. I was away from the home 20 so I purchased yet another $29 VGA adapter from the Apple store to complete my mission.
Moral of the sad story - Buy a DVI-I to DVI-D adapter if you own and use a MacBook for presentations. The Apple Store does not carry them.
Hey wait a minute is this tied to the disappearing Firewire connector???
Mike
PS - I was ablt to find a DVI-D to HDMI connector that I will try when I get back home...stay tuned!!

Mini DVI - VGA Issue

I purchased a Mini DVI-VGA adaptor from Apple over a year ago. I've used it only to connect my Macbook to a projector. Once connected, the screen will flash briefly and then the resolution will change and I will be able to switch back and forth from single screen to dual screen by clicking F7...but this was back when things were beautiful and I had no issues.
Now, my adaptor will not work...neither would another Min DVI-VGA adaptor that I tried...but yet the port will work when I connect my Mini DVI-SVideo/RCA adaptor.
Is there a setting that I may have changed? It doesn't seem to be a hardware issue because the port will work with a different type of adaptor.

Hi. I have pretty much the same problem: everything was fine until yesterday. As usual, the screen flashed briefly but then the resolution DID NOT change and the projector could not connect. After removing the adaptor, the screen flashed again but that's it but there was no difference as the resolution had not changed. To note that the adaptor is (grrrr) new (bought about a month ago). Could it be an issue with MAC OS 10.6.2? or maybe the firmware needs an update? I'd be glad if someone could help. Cheers,

Mini DVI to VGA Adapter Issues

Hey guys,
My first ever post to the forums. I just recently bought my very first apple computer. It is a 2.4 ghz Macbook 13" and bought a Mini DVI to VGA Adapter so that I can connect it to my 46" Sharp AQUOS TV. I connect my laptop with the dvi to vga adapter plus another vga cable of course and all I get on the screen is my wallpaper but I can't see any of the icons on my tv screen, nothing.
Can anyone help me on this? Does this sound like a familiar problem?
I would appreciate your help.
Thanks in advance,
Dogan

Mini Dvi to VGA for Projector issue

I recently bought a mini DVI to VGA adapter for my new macbook Black 2.4 ghz. When I hook this up to the projector nothing comes through, but the computer recognizes the projector. I know it is not the projector because when I plug in my 12inch powerbook it instantly recognizes the computer and displays whatever is on the screen. I even returned the adapter for a new one and am still having the problem. Is there something I'm doing wrong? Are there steps that I'm not doing, or is there something wrong with the mini dvi on my macbook?

When I attach my MacBook to a projector via mini DVI, all variations of order of activation used, the desktop image appears, but the icons and other open pages are off the screen to the right.
Of greater importance, Keynote presentations appear as two slides side by side, with a timer under the left image and no transitions.
This has happened with two portable projectors and one overhead, exactly the same images with each.

Mini DVI to VGA issues w/ LCD HDTV

I have looked all over and I can't find a solution.
I recently purchased an LCD HDTV, Insignia Brand which is a Best Buy Brand, and I bought a DVI cable to hook up to my Powerbook G4 using the Mini DVI to VGA cable. When I hook it up to my tv it works, but the screen on my Powerbook looks magnified as does the LCD TV. When I launch Safari or any other program it doesn't fit on my screen or the LCD TV and I have to resize it.
After I look at displays in system prefernces it says my max resolution is 1024 x 768.
Any help would be appreciated.
Jeremy

Just guessing - the TV's "VGA" input is limited to 1024x768, which is possible although some "VGA" inputs will work higher. Do the instructions mention a limitation like this?
I think if you turn off mirroring on the Powerbook, at least the Powerbook screen will have normal resolution, and the TV 1024x768. The TV apparently scales up image to fill the screen unless using HDMI, where is leaves the extra 342 pixels blank on the sides (1366-1024). Perhaps the TV has a mode for adjusting how the TV handles lesser resolutions (stretch, dot-by-dot, etc)

Mini-Dvi to HDMI or S-video, also sound issues

Hello,
I want to connect my iMac with a Mini-Dvi port to a TV and want to hear the sound from the TV.
What adapters will i need to hook it up to a HDMI port, and will this connection also produce sound on the TV?
If that can't be done can I use a s-video adapter, and what about sound?
Last, do they have longer cables so you don't need your computer right beside the TV?
Thanks

You'll need Apple's mini-DVI to DVI adaptor plus a DVI-to-HDMI cable
(or a DVI-to-HDMI adaptor and an ordinary HDMI cable).

No. There are no audio signals on the mini-DVI connector. You'll have
to run a separate audio cable from the iMac's audio output to the TV.
The iMac's audio output is a "combo jack" that supports either analog
or digital (optical S/PDIF) audio. Your TV probably has an analog audio
input associated with one of its HDMI channels.

Mini dvi to hdmi connection issues

Trying to set up my 2007 imac to my Panasonic tv. I have a mini dvi to hdmi converter and an hdmi cable connected to my tv. I only get a blank screen on the tv, but it seems that the computer is connecting. When i go into sytem preferences for display monitoring I get the second screen saying Panasonic and set up which reolution I want but theres no way to detect the display. Any help getting picture would be greatly appreciated!!

Do you have the correct HDMI input selected in the TVs menu...?
Aditionally, there might also be settings for connecting a PC to the TV.

Mini-DVI to HDMI Issues

I have an early 2008 Macbook and have been using a Mini-DVI to HDMI adapter and HDMI cable to connect to my TV. It was working great until I upgraded to OS X Lion. Now the video is laggy/glitchy on the TV and the computer when the cable is plugged in. Any help?

Try gently moving the adapter into different positions. My mini-dvi to dvi adapter will only work if it is tilted upwards at about a 20 degree angle relative to the tabletop. I usually wedge a pen or a pencil below it to hold it at the proper angle. It's a little redneck, but I like shopping at walmart and only spent $5 on the adapter.

Mini-DVI to DVI Adapter issues (2 different types, no info from Apple)

as you can see below, I have an iBook G4 1.2GHz
three weeks ago I got a Mini-DVI to Video Adapter
there were two different types in the Apple Store because there are two generations of Mini-DVI outputs, therefore some close inspection and it was easy to get the right part.
Now, three weeks later, all that stuff is off the shelf so it looks like they only have up the more recent size plug. Thus, I cannot find the slightly smaller Mini-DVI to DVI Adapter. (typical Apple, probably just wants me to spend more money on a new machine)
Anyone have a line on where to buy the older type of adapter?
be very careful out there. They are pimping the heck out of the newer generations. I'm looking for the older one.
(if not, I'll probably just stop buying Apple stuff. No need for the headache any more since they are no longer really different products. Just fashion)

I have both an iBook G4 and a MacBook, which use each of the adaptors you have described. I found the information on the Apple site by identifying the Model iBook I had, Dual USB, and looking at he detailed views of each model to identify the type of 'video output port'. I obtained a '2 input' VGA switch from Tiger Direct to be able to switch my monitor from iBook to MacBook.
Hope this helps!
