Macbook mini-DVI - DVI - HDMI not working with My 32" Vizio

Okay so my Macbook mini-DVI - DVI - HDMI is not working with My 32" Vizio. I've connected an 18 pin plus one slot DVI to HDMI cable to my 32" Vizio HDTV, this cable is connected to my macbook via a Mini-DVI to DVI cable, this one has 24 pins plus one slot on the DVI side. My Vizio display is blue, no signal, it reads. I'm wondering if the reason it's not picking up the display is the lack of pins on the DVI to HDMI or because I dont have any display options aside from screen size and color on my display menu. BTW I hit the detect display button and nothing happened.... I know I just wrote alot here but hopefully someone will read it and come to the rescue. thanks

Oops, I guess all I had to do was restart my macbook. I feel like an idiot.....all is well.

MBP CD2 DVI to VGA not working with projector

I am having issues getting the MBP to recognize a DELL 2300 projector through a DVI to VGA apple cable.
A few months ago there were posts about this, but no solutions. The problem seems to be with the 'INTEL' side of things, as the same projector with the same DVI to VGA apple cable works on an older G4 tower running 10.4.9. The projector also works on an old G4 iBook with it's version of a VGA adapter. To make things more confusing, a DVI to Video apple cable works with the DELL 2300 on my new MBP C2D-but produces a terrible quality picture. Mysteriously, my previous 1st generation MBP CD worked with the DELL 2300 via a DVI to VGA apple cable (but I'm not sure which OS was out at the time 10.4.8?)
My new MBP CD2 definately recognizes the projector through the DVI to VGA adapter, but the projector doesn't recognize the video signal from the computer. It is DEFINATELY the MBP (or universal drivers), as I have checked the DVI to VGA dongle (works), have checked the projector (works with an ibook running 10.4.8 OSX with VGA dongle), have changed resolution settings before and after connecting, have restarted computer, have tested various orders of connecting the projector and cables. STINK! (I also have TWO DVI to VGA adapters, so it is not a bad adapter). I have also played with exchanging various plist files from older universal versions of 10.4.8 that worked with the projector-no help.
As I stated, the projector will work (in horrible quality) with a DVI to Video dongle. Why it will not work with the DVI to VGA dongle is a mystery and annoying I would hope that a newer MBP CD2 would be plug and play (like my previous MBP CD and an old G4 tower and an old iBook G4...but no).
Any ideas, any help, any answers?

Here are the actors in our play today
1. MacBookPro A. (my system a CD2 2.16 with OSX 10.4.9)
2. MacBookPro B. (my friends system a CD2 2.16 with OSX 10.4.9)
3. an iBook (my friends 1.07 GHz G4 with 10.4.8 and a VGA adapter)
4. DELL 2300 MP projector
Plugged in DVI to VGA adapter to the virgin MacBookPro B (never had the projector plugged into it before) Dell projector shows that it recognizes an analog RGB 800X600 signal from MBP B. It projects a beautiful desktop. All is well for a moment.
In Display preferences we see for the MBP B
Color LCD, Display: 800X600 stretched, Colors: Millions, Refresh Rate: N/A
VGA Display
Now, I unplug the DVI to VGA adapter and naturally MBP B readjusts to it's native resolution. Great.
Now I immediately plug back in the DVI to VGA adapter. The computer and the projector searches for signal with none found, while the computer shows no attempt at an automatic readjustment as above (800X600 stretched).
I try the 'detect display' option. It causes computer to stall for a second (as it searches) but it does not detect projector and does not readjust it's own resolution to 800X600 stretched as it did initially. F7 key does nothing.
This is a problem!
So, I shut down the projector. I unplug the projector's power source and waited 20 seconds. plugged it back in, started projector back up.
I shut down/restarted the MBP B.
I plug back in the DVI to VGA adapter into the MBP B. The MBP B screen flashes to all blue, but does not automatically change to 800X600 stretched (remains at native resolution and does not recognize an external monitor/projector)
Enter the iBook!
I plug the iBook's VGA adapter into the projector. The projector shows that it recognizes an analog RGB 1024X768 60Hz signal and projects desktop screen immediately. Plug and play!
iBook display prefs reveal:
Color LCD, 1024X768, colors: Millions, Refresh rate: N/A
Color tab: Generic RGB Profile
VGA display, 1024X768, colors: Millions,
Now. I unplug adapter from iBook, iBook readjusts to native display
plugged back in adapter to iBook, immediately recognizes and displays projected desktop.
Scene 2: The FREAKY thing!
Now, I immediately (after unplugging the adapter from the iBook) change adapters to the DVI to VGA adapter and plug the projector into the MacBookPro B, whallla! Back in business. (computer screen adjusted to 800X600, and projector recognized signal).
Now, what about my computer? I unplug from MBP B and plug into MacBookPro A, and NOTHING...the computer doesn't automatically adjust to a new resolution, and the projector doesn't recognize any signal from the computer.
Ahhhh Freak out! Now, I plugged adapter back into MacBookPro B, and now back to NOTHING. MBP B no longer recognizes projector or readjusts it's resolution. Was something somehow corrupted?
Now, I plugged iBook VGA adapter back in, and iBook once again with it's awesome G4 technology (or dated video drivers or something) recognizes the projector in an instant and projects the screen.
Now, logically I try again to immediately unplug the adapter from the iBook and switch adapters and plug back into MacBookPro B-it worked once right? But, sorry, NOT twice. The mystery deepens.
Well, I think, maybe it is because I didn't restart MacBookPro B before attempting the switcharoo from iBook to MacBookPro.
So, I plug back into iBook-projector. And the iBook works immediately again.
I restart MacBookPro B and plug in to the freshly restarted MBP B...HOUSTON WE HAVE LIFT OFF! The MacBookPro B recognizes the projector and the projector kindly displays the desktop.
Now what about MacBookPro A...Last time, when I did the switcharoo, it corrupted something to cause the MBP B not to work. Let's try it again. Will this plug-unplug-restart-switch adapters-immediatly plug in technique work...let's see. I restart MBP A, and plug DVI to VGA adapter in. Sorry. Same ol' no signals recognized. MacBookPro A not auto readjusting resolution, and does not list any projector in display prefs.
Let's get crazy and immediately plug the adapter into the MacBookPro B...it works-oh so logical...NOT! Why wasn't it corrupted this time by MBP A? MacBookPro B readjusts its screen to 800X600 stretched and projector immediately recognizes and projects desktop.
Now lets see if I can break it again as before. I unplug it from MacBookPro B and back into MacBook Pro B, knowing that this caused it to stop working previously. And...it still works-WHAT? I do it a third time. It still works on MacBookPro B.
So,
I plug it back into MacBookPro A...still nothing. Back to MacbookPro B works like a charm. This time it struggles a bit showing that initially it sees a signal from MacBookPro B of 1192X900 (i Think), then the MacBookPro B switches automatically to 800X600 and the projector works.
Wait..I see something amiss! I see in my MBP A menu bar an icon for Labtick which MBP B does not have. I shut down Labtick, plug back in the DVI to VGA adapter and 'Boom' the projector is recognized.
I unplug DVI to VGA adapter and plug back in to MBP A and 'Boom' the projector is recognized again...no it couldn't be!
Well, it is possible it couldn't be because, I shut down the projector, unplug it's power source, plug it back in. I plug it back into the recently working MBP A with Labtick not running, and sorry folks, now the projector doesn't work again. The MBP A does not readjust it's resolution, nor recognize a projector and the projector doesn't recognize the MBP A.
Let's try the projector in MBP B....same deal. Now it doesn't work. Same symptoms of MBP A.
Back to the good ol' iBook. Of course it works.
Now switching over directly to a restarted MBP B. -DOESN'T WORK (as it did using this technique previously)
Now switching over to MBP A- DOESN'T WORK.
As you can see, it is hard even with multiple computers to find a series of doing things that consistently makes the projector work.
Any thoughts, ideas, ways to diagnose? Thanks!

Mini port to HDMI not working

Trying to connect iMac to my TV with mini port to hdmi genuine adaptor with no success. Works ok if I connect iMac to works Microsoft laptop, it displays immediately. Then connect Microsoft laptop to TV , absolutely fine.
I have looked on Internet & apparently in Display on iMac , arrangements should appear but doesn't on mine.
Any suggestions welcome please.

Hi, thank you for your response.
I think it was my terminology.
What I bought today from PC World was a IMDHDD13 Mini Display Port adaptor which they advised would work!
It plugs into the thunderbolt port on Mac, screen turns blue for a couple of seconds then returns to normal.
In DISPLAY, arrangements doesn't appear & if I search it, it tells me it is hidden because there is no other screen connected.
I'm thinking now after reading your post this is not a genuine apple part PC World have sold me!

MacBook Mini-DVI to HDMI not working on Vizio VO22LF 1080p

I recently purchased a mini-DVI to HDMI adapter so I can hook my macbook to my Vizio 1080p LCD TV. The macbook detects the TV correctly but no matter what I do the TV never detects the macbook on the hdmi input.
Doing some searches I saw discussion of a bug with 1080p that and a trick to get two 1920x1080 resolutions to show up in the display options but it never works for me.
When I connect to my 42" Panasonic 720p everything works great.
Any thoughts??

This sounds a lot like the problem relating to an Apple disclaimer about the mini driving non-coherent displays which seems to especially affect the original G4 mini. See here under the "Video" sub-section:
http://support.apple.com/kb/SP65
The problem is the timing for 1680 x 1050 will often have a dot clock above 135 MHz. There are really only a couple things you can do; one is to use the VGA interface as you have been and the second is to use a program like SwitchRes X to lower the pixel clock and stay with the DVI interface. If you want to go the SwitchRes X route, download and install it (get the SwitchRes X Control Panel version and not the full version of SwitchRes X) and then write back to this thread and I can take you through the steps you need to perform. You can also get more info from this thread:

Macbook late 2009 mini DVI to HDMI not working

I never had a problem using my external TV with my macbook untill now. I always connect it using a mini DVI cable to HDMI to TV. It worked pefectly for a while. But recently it stopped working, when i plug in my macbook to TV it shows a blue screen for few seconds and then nothnig. there's no signal on the TV.
Any resolution will be appreciated.

I Started seeing this on my Mac Mini attached to my HDTV from DVI to HDMI after upgrading to 10.5.8.
I am running Spaces. Are you? Is it possibly related to this? I have seen a couple times where the screen was blue for some time and after pressing CTR-Left Arrow
to switch spaces, I would get my screen. Try switching spaces with the keyboard shortcut and see what you get.

Xserve's mini displayport (dvi to vga) not working with snow leoapard

I am using a Acer 20" display with the mini displayport to vga. and since I updated to snow leopard it is not working anymore. If I change the resolution it is recognized but it is a very bad resolution and as I have a wide screen the resoltion that works looks horrible.
I saw that the update 10.6.2 had some updates including mini displayport problems, but it seems like it did not fixed the problem that I have!
I tried to call the apple support hotline but I got kicked out twice after the agent asked for my serial number and online I could not find anything that could help me to fix my problem.
so if there is someon out there with the same problem or an idea how I can fix that problem I would be very happy!
greetings from spain / barcelona!
cheers!

If there are listed options available, changing the refresh rate of the display frequency in the Monitors preference pane will sometimes yield better results at given resolutions.
I have to Xserves connected via a KVM switch to a CRT monitor; one Xserve is using the DisplayPort/VGA adapter, the other is straight VGA from the video card. I had to fiddle with the refresh frequencies to get the images to come close to matching.

Why won't my mini dp to hdmi adapter work with my hdtv?

I recently bought a 2011 Macbook Pro 13" notebook, and the girl who sold it to me also sold me the Moshi mini display-port to HDMI adapter. She said all I would need to hook my laptop up to my Vizio LCD hdtv was that adapter and a regular HDMI cable. So I've now tried to hook them up no less than 10 times, and nothing still. The only thing that happens is, my laptop screen will turn blue and adjust the screen size as if it's trying to adjust to the TV, and my TV will say "retrieving data." So it looks like it's getting ready to connect, and then my computer screen will go back to normal, and my TV will then say either "not support" (whatever that means) or "no signal." Now I know there is nothing wrong with my macbook, since I have been able to hook it up to the TV with my friend's adapter. I thought she had the same adapter as me, but now that I really look at it, I think it's a display-port to VGA adapter. Plus the cable she uses is something other than an HDMI cable. Does anyone know why my adapter isn't working? Or is it possible that it's just faulty and I wasted my money? (Note: I've tried adjusting the resolution, display, etc, and nothing makes a difference).

I too experienced the same issue. Here are my details:
Recently I bought a 15” Macbook Pro and last night I tried to connect and use a Edirol FA/66 Firewire 400 connected outboard audio interface using a Firewire 400 to 800 adapter then connected to a Firewire 800 to Thunderbolt adapter since the MBP doesn’t have a native Firewire port. What I observed is that the Edirol was not getting power from the bus nor did the MBP (running Yosemite) recognize the Edriol. At first I thought there was a problem with the Edirol since I haven’t used it in a while but when I connected it to an older MBP that has a native Firewire port, it worked normally. Is there a known issue with these sorts of external audio interfaces working properly with newer MBP running Yosemite? I’m hoping that a software update will fix this issue.

Mini Display to HDMI not working

I currently have iMac connected to toshiba tv through minidisplay adapter to hdmi. We can't seem to get it to recognize that the tv is hooked up, we've tried unplugging and replugging turning each device off and on in different combinations. here's what I get on the "display" menu when everything is hooked up.
os x 10.8.2

I had said to my husband that it's probably the adaptor but he didn't think that could be the cause - thanks for confirming that for me! All I can find about it the iMac is this if it helps...21.5-inch, Mid 2011,Processor 2.5 GHz Intel Core i5. I had read that some older macbooks needed to go mini display, to...dvi and then hdmi I think it had said. I was hoping that would've been resolved with thunderbolt. I'll check and see if we can exchange the adaptor. Thanks again! (and I would've been a bit more polite if I felt like they weren't being saucy with their response )

Macbook Pro 2011 DVI HDMI out does not work with TV when the power cable is connected

My Macbook Pro (Early 2011) DVI HDMI out does not work with TV when the power cable is connected. If get the blue screen and then can use the macbook but nothing is displayed on the TV. If i go into display I can see that there are two screens but nothing displayed on the TV. If i take the power cable out at this point the TV shows the second desktop as expected. If i then reconnect the cable, the screen flickers, as though it is being affected by the power cable, and the screen goes blank on the TV. Only if i remove the DVI cable do i get the blue screen again. If i remove the power cable and reconnect it will do it every single time, so i cannot see it being a TV issue or a minor glitch.
I have had this working previously but at the minute it seems to not be playing ball....any thoughts
Thanks

BUMP
Any ideas?

Will the Apple mini DVI to video adapter work with a macbook? What to Buy?

I went to my local Apple Reseller and asked for a mini dvi to video adapter to use to connect my macbook to a tv using either s-video or the yellow RCA cable. I was told that they only had the one that was for an ibook and Power book and that this would not work with a Macbook. I would need a different one. Is this correct. If so, what do I need? I have looked on the online Apple Store and cannot find anything that fits this description. They only list one type of Mini DVI to tv adapter? I just want to be able to connect my Macbook to a TV.

As it happens, I just bought the mini-DVI to video connector for my wife's Macbook (C2D) yesterday. I am in Australia (which is a PAL country), but I didn't see anything on the device or the packaging which indicated it as being PAL-specific. In fact, in Display Preferences when it is connected to the Mac and TV and in use, the panel relating to the TV output (which is shown by the Mac on the TV screen) is where you select between PAL-50Hz and NTSC-60Hz, so I'd guess it is a single worldwide device, rather than their being separately-manufactured PAL and NTSC variants of the connector.
Anyway, on the back of the top cardboard part of the packaging is a picture of the connectors (because you cannot really see the pins in the Mini-DVI connector itself when packaged, due to an opaque plastic "keeper" over the end of the plug).
To reconfirm what is said above, the pin configuration on the mini-DVI port on the MacBook and what you need on the Mini-DVI connector is a horseshoe or "U" shape. I don't remember if any specific model of Mac is listed, but I believe as long as it is that U-shaped connector you'll be fine with the same connector kit.
The "mini-VGA to video" connector is not what you want for a MacBook; mini-VGA is not "U"-shaped inside, but rather two rows of pins in "II" configuration (even though the outside dimensions of mini-VGA and mini-DVI look very similar).

External Monitor Not Working With Macbook Pro

My computer was working fine with an external monitor, then my computer froze, and I had to hold down the power button. When I turned it back on, my computer would not work with an external monitor. I've tried different cables, so it's not the cable. The monitor is being detected by the computer, but nothing is showen on the external monitor. When connecting the monitor to the computer, the computer's screen goes blue, then turns back to normal. I
I cannot reset the SMC by removing the battery, I do not have the confidence to remove my battery, and do not have the time to send the computer to someone else to do it.
I also tried updating my OS from 10.7.4 (Might've been 10.7.3) to 10.7.5.
My computer is a MacBook Pro (13-inch, Mid 2010), running OS X 10.7.5 Lion.
I need to get this problem fixed ASAP, any help is appreciated.
Kind Regards,

I forgot to mention, I'm connecting the monitor via MiniDisplay -> HDMI. I've also tried USB -> HDMI and USB -> DVI -> HDMI but none of them seem to work.

Will a DVI to HDMI adaptor work when connecting the ipad2 to a projector?

Will a DVI to HDMI adaptor work when connecting the ipad2 to a projector?
I have connected my ipad2 to my HDTV and it works perfectly. I'm trying to connect the ipad to either the DVI port on my classroom laptop or to my Promethean board so that I can mirror educational apps for my students. Does anyone have suggestions on how to make this work?

No, there's not any damage to your MacBook.

The TV is working with my Windows laptop (analog and digital). I really have no idea where the problem is. Somebody can help me?
