Mini DVI to DVI monitor Kernal Panic

I have a 20" iMac Intel Core Duo, mini DVI to DVI-D adapter, cable, and Princeton 17" DVI-D monitor. When I hook up the monitor to the iMac I immediately receive a Kernal Panic. If I restart, it also results in a Kernal Panic. It does not matter if the monitor is on or off. No monitor, no Kernal Panic. The monitor does work with a VGA adapter on a mini mac and on a G4 PowerBook. I don't have a mini DVI to VGA adapter for the iMac, so have not tried that yet. But I'd much rather have it work with DVI. Any suggestions?

did you try running a repair disk, to see if it is software related?? you could also try pram reset. (apple-option-p-r at start up, and hold til you get two sets of chimes). you could also unplug power from power supply at back of mac mini and plug it back in after a few minutes. if none of these things worked, i would contact the manufacturer of the monitor.

Mavericks + Reboot/kernal panics when Mini DVI to DVI adapter plugged in to 2008 iMac

Hi, i'm encountering a problem with my brothers iMac from 2008. We are attempting to add a 2560x1440p external monitor. When I first plugged in the cable, along with the Mini DVI/DVI adapter, the computer reboot, went to the grey screen, and then said "Your computer restarted because of an error, press any key to reboot" type message, then does it again. I tried plugging in just the adapter, and got no kernal panic, so it's only when info/power is transmitted through the cable.
I googled it extensively but couldn't find any solution nor even a hint of a solutiion. I suspect it might be the graphics card (ATI Radeon HD 2400), but I don't know. A few years ago we connected a 720p TV using a MiniDVi/HDMI adapter, and it worked, but the resolution sucked and it was more of an experiment.
I should add we installed Mavericks yesterday if it makes any difference. I also asked the seller and and he confirmed the adapter was a DVI-D, which is what the external monitor requires. Here is the Problem Report given after removal of adapter and reboot. Thanks for any help.

I just plugged in the MiniDVI/HDMI adapter cable and I got a really flickery TV, does this suggest graphics card issues? If so how to I run a diagnostics test on Mavericks if I don't have the boot DVD? Thanks!

HT3153 Can the early 2006 MAC mini support a DVI to hdmi adapter for TV monitor support?

Can the early 2006 MAC Mini support a DVI to HDMI adapter for a TV Monitor?

Hi, I can't see why not...
Supports digital resolutions up to 1920x1200 and analog resolutions as high as 1920x1080.

Monitor won't work via mini-dvi to dvi adapter

It's a brand spanking new mac mini. I attached a 5 year old lcd monitor (always used before as VGA) using the mini-dvi to dvi adapter. I am using the monitor's dvi connector. The monitor resolution is 1280x1024.
The monitor does not work when using the mini-dvi to dvi adapter. If I remove the mini-dvi adapter and use a mini displayport to dvi adapter, it works just fine. I can keep both adapters plugged in and plug the cable into one or the other. It always works instantly when attached to the minidisplay port and doesn't work if I switch to the mini-dvi port.
I've tried the display with mini-dvi adapter on my macbook too. On the laptop, it acts like there are two screens attached, but there is no action on the external display.
As a further test, I attached the mac mini to the TV via a mini-dvi to hdmi adapter. The mini-dvi port on the mini works fine, as does the port on the laptop. The monitor works fine via minidisplay, but not mini-dvi.
Naturally, I concluded that the mini-dvi adapter was faulty. A second adapter came today, and nothing has changed. Could I have received two Apple mini-dvi adapters in a row with problems? Is there something about the monitor that doesn't like the mini-dvi port? It seems like it wouldn't like the minidisplay port either, but that one is fine.

• Went to Best Buy
• Paid for a DYNEX Mini DisplayPort to HDMI Adapter ($25)
• Came home and plugged in the adapter then the HDMI to DVI cable to the monitor. (Note: Monitor is a LG Flatron L22WTG) - DID NOT WORK
• iMac knows monitor is plugged in and I can change the resolution on both monitors and mirror. (Note: Changed to every resolutions with/without mirror image.) - DID NOT WORK
• Restarted computer - DID NOT WORK
• Turned off/on LG monitor many times - DID NOT WORK
• Unplugged/plugged back in many different ways - DID NOT WORK
• Changed the HDMI to DVI cable with a better cable - DID NOT WORK
• Installed BootCamp with Windows 7 - *BOTH WORK 100%*
• Rebooted to OS X 10.6.7 (Snow Leopard) - DID NOT WORK
• Installed Windows XP - *BOTH WORKED 100%*
• Reinstalled OS X 10.6.4 (Snow Leopard) - *BOTH WORKED 100%*
• Updated OS X from 10.6.4 to 10.6.7 - DID NOT WORK
Seems to be a driver problem with the new update (10.6.7). I will not update again till drivers are fixed.

Have I power down Macbook and monitor (or TV) before connect (or disconnect) through Mini DisplayPort to DVI (or Mini DP to HDMI) Adapter?

Can I hot plug monitor (or TV) through Mini DisplayPort to DVI (or Mini DP to HDMI) Adapter? Or I have to power down all before connect/disconnect through Adapter?

Thank you, Mario.
I just wanted to be shure because previously i destroyed two videocards on my pc by plugging hdmi without power down.

How do I connect my Mac Mini (DVI) to a monitor (VGA) and 2 TV's (HDMI)? What equipment do I need?

I have an older Mac Mini with a DVI out. Right now using a monitor with VGA in, and since my Mini came with the adapter, all is good. However, I'm trying to use this setup to also connect 2 50" TV's that have HDMI's. What would be the proper setup in order to run the mini and the monitor along with the TV's? Thanks!

You need USB to video adopters. See:

Mini DVI to external monitor (VGA) problem/firmware update does nothing

Hi,
Four months ago I bought a new white 13-inch Macbook (2006 model I believe) along with a handy mini-DVI - VGA adapter. I used a Hanns-G HU196D external monitor which worked fine for a couple of months but then stopped, and had the same problem with a (much cheaper) 'LiteView' monitor. I find it bizarre how they work absolutely fine and then stop, with no damage to the adapter, cable or ports. I've since bought a new adapter and cables + trying out a different monitor and still the same problem...
I've installed a firmware update that describes the exact symptoms, but it's done nothing. Can anyone help me resolve my issue?? It's still under warranty so is it an unusual problem that'll need to be fixed by Apple?
Thanks

Are you using the mini DVI to DVI followed by a DVI to VGA adapter? That may not work if the mini DVI to DVI adapter does not pass analog video. If that is the case, you need the mini DVI to VGA adapter:

Mini DisplayPort to DVI not working, No Multi-Monitor, Jerky Mouse

I have an iMac, 27 inch, 2009 model.
Until today I've had a second monitor attached via the Mini DisplayPort to DVI adapter. The monitor is a Samsung SyncMaster T260. This setup has worked perfectly well so far.
Until today that is. Now the monitor is not recognised any more and if I try to select "Detect Displays" the mouse pointer hangs every few seconds - stops dead and then restarts again.
What did I do to make this happen? Nothing (that i'm aware of). Haven't installed anything, not done a software update, just literally rebooted and it's not working anymore.
_*Things that still work...*_
The Mini DisplayPort to DVI adapter works on a Mac Mini, so that's OK
The DVI cable works fine when plugged into a PC or Mac Mini, so that's OK
The Monitor works fine when plugged into a PC or Mac Mini, via DVI, HDMI or VGA, so that's OK
So I've established that, in isolation, each part of the system is functioning perfectly well.
*_Things I have tried - without success..._*
1) Rebooting - both iMac and monitor
2) Unplugging all cables and reconnecting then rebooting again
3) Clearing the PRAM - done it twice just to make sure
4) Updated to OS X 10.6.7
5) Reset the SMC
6) Deleted the com.apple.windowserver.plist files at /Library and ~/Library
7) Googled for solutions - plenty of people seem to have one or the other of these symptoms...
Can anyone shed any light on what's happened here ? Please help!

** Sorry if this is in the wrong place, I just found a forum specifically for the iMac so posted it there but not sure how to delete this one. **

Well, it would be interesting if that's when it had occurred. At the time, I hadn't installed 10.6.7, and hadn't installed anything immediately prior to the problem occurring.
It doesn't seem like there's any way (a-la System Files Checker on Windows) of checking the integrity of system files which may have been corrupted, nor a way of reinstalling any update in the case of this happening - or is there a way of doing this? You don't seem to have any control over updates apart from applying them - if something does go wrong, there's no way of backing out. I guess Time Machine is the answer to my own question there.
I'm happy that it's working now, but it was a pretty extreme fix to have to wipe the entire system. At least it wasn't a hardware issue, I'll be thankful for that!

Mini dvi to dvi adapter not working with monitor

arright *** i got a mini dvi to dvi adapter which is connected to my vga monitor through a vga to dvi adapter. The computer recognizes the monitor in display preferences, but the monitor doesn't display anything it just sits in standby mode... any ideas why this isn't working? You'd think if the problem was going from vga-vga to dvi adapter-dvi to mini dvi adapter that it wouldn't even recognize the monitor but it does.
well that *****, back to best buy to get the other one. Reason i got the dvi one is because i plan on getting a different monitor with dvi soon. But noo dvi adapter wont work with vga adapters.

The mini-DVD to DVI adapter doesn't pass through the analog video signals needed for VGA, so won't work with a DVI to VGA adapter. All the control signals are there, so the display is recognized, but there will be no picture.
They could have used a DVI-D connector on the adapter, instead of DVD-I, so the DVI to VGA adapter wouldn't even plug in, but then it couldn't be used with some non-Apple LCDs, that use DVD-I connecters.

My Viewsonic monitor won't work with the Imac using the Mini Port to DVI adapter.

My Viewsonic monitor won't work with the Imac using the Mini Port to DVI adapter. I also tried the HDMI to DVI adapter ane the Mac-Mini with same result. The monitor does work on my older Macbook Pro that has the DVI connector. Is it a Software/Driver issue ?

Should be extremely simple, please carefully read Connect multiple displays to your Mac. If you still have problems then it's probably a cable issue that would be resolved by replacing the adapter cable. You should be using this adapter. If you are using a third party adapter that might be your problem!

Mini DisplayPort to DVI Adapter - Monitor not recognizing

I have a new MacBook purchased last month from Apple to replace an older MacBook. I used a Scepter X20 monitor on the previous MacBook with an adapter with no problem. With this new computer, I had to puachase a Mini DisplayPort to DVI Adapter. I plugged it in as I did for the other computer, and the monitor doesn't recognize it at all. I checked the monitor by plugging it into another Mac (older version) with adapter and it works fine. Why will my Mac not recognize the monitor or the monitor recognize that it is connected?

On the very slim chance this might be problem, it happened just last week to another poster and it's happened to me, the mini display port really takes a good shoving into the graphics card. Sometimes it will look perfectly seated in there, but it's not quite.
Aside from throwing that out there, I would think if that wasn't the case, you may be having problems with the adapter itself. The whole mini display port is ridiculous in itself, but the two lessor expensive adapters I bought from Apple worked very poorly anyway. And on Apple displays!
The $99 dollar one Apple sells has a reputation for working the best, but I haven't tried it. There are also devices now, still pretty expensive, that seem to bypass those altogether.
I can't say if some other issue is going on or not, there may be. But just know you're not alone in having display problems of this kind.

Mini Displayport to DVI Adapter not sending signal to DVI Monitor

I have a dell monitor connected to my Thunderbolt Display that will not get a signal. The component string looks like this
MBP - Thunderbolt Display- Mini Displayport to DVI adapter- Dell 22" DVI monitor.
I would like to use this monitor as a third monitor instead of collecting dust. Any help would be appreciated.
Thanks,

Hello fuzzymelton,

2nd monitor through mini-dvi to dvi gives wierd tinge around window

My Samsung monitor, which before using with my new Mac, produced a beautiful picture. Now that I just hooked it up with the mini-dvi to dvi toggle, any window that shows up on the Samsung has this sort of wierd glow,tinge surrounding the whole window. Like an aura. I tried to tweak the profile ,brightness etc to no avail. I think the toggle I bought was from Belkin )looked exactly the same and much less expensive than the Apple product).I doubt it that is the culprit. Anything that I can do to get a crisp and true reproduction of whatever I might place on that matter? Settings that I should look at? Or should I , in general be not expecting anything so great by using the second monitor. Thanks

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.

Mini DVI to DVI monitor working

I have a Black MacBook running 10.7.3. I have ta Bookendz and a mini DVI to DVI aadpater and two differnet DVI cables. I have tried all combinations and can not get my LG monitor to display anything, it just goes into power saving mode. My MacBook sees the external monitor in the display prefernces, and even has the right resolution set. When I first had the monitor it wouldn't work through and I was going to send it back, but it just started working.
The monitor works fine when plugged into a Mac Mini, or through the HDMI and VGA ports when plugged into my MacBook. Any help greatly appreciated.

The mini-DVD to DVI adapter doesn't pass through the analog video signals needed for VGA, so won't work with a DVI to VGA adapter. All the control signals are there, so the display is recognized, but there will be no picture.
