Second Apple Display via DVI

I'm sure this must have been covered before so apologies if I'm going over old ground, but can't seem to find exactly the right answer to my question, so if anyone can help or point me in the right 'post direction'.....
I have a MacPro 4.1 with a Mini DisplayPort output plus a DVI output. I've been running a 24" Apple Display (via the MDP) and a standard monitor (via the DVI) quite happily.
Now want to upgrade to a second 24" Apple Display, but obviously can't connect to the DVI output due to the hardwired MDP from the monitor. Assumed that I could buy an adaptor (male DVI to female MDP) but can't seem to find anything......
There must be a way around this issue....?
Thanks

External display (via DVI) takes 10 minutes to turn on

Hi!
We have a 15" G4 Powerbook about 16 months old. We often use it with an external (non-Apple) LCD monitor, in dual mode, via DVI. For most of the time we've had the PB, there was no problem at all. However, in the past few months a puzzling problem has developed. When the monitor is plugged into the PB's DVI port, the PB will believe there are two monitors available but it will not send any signal to the external monitor at first. After about 10 minutes, it will suddenly start sending a signal to the external monitor and everything is fine. However, if the PB subsequently is allowed to go into sleep mode, upon resuming it again refuses to send a signal to the external monitor for about 10 minutes.
Any idea what is going on and how this might be fixed? It's really frustrating.
Thanks!
G4 AlPB 15" Mac OS X (10.3.3)

I think I have this problem as well, I keep using the PB with LCD projectors, again they are detected, but I can't get an output.
Not sure I get anything after ten minutes though, I'll leave it today to try it.

Macbook can't detect external display via DVI cable

I just bought Samsung PX2370 monitor and attempt to connect it with my Macbook Aluminum (late 2008). I have mini display port to DVI adapter and DVI cable. When I hook up my Mac, nothing comes up. The screen on macbook goes blue briefly and then back to normal, but nothing has been detected. I've manually set the source of signal to DVI, and tried to use Detect Display but nothing happens. Even I try to detect the monitor by using Windows 7 (via bootcamp), the display remains idle.
I had tested the monitor using DSLR although by HDMI, it work.
Any help would be much appreciated.

Hey hparekh and welcome to the forum -
It looks like you have the correct hardware. You should check your connections... make sure your using the Mini DisplayPort and not the Ethernet port (common mistake) and all of the connections are plugged completely. Make all of your connections with your MacBook on and then turn your Dell on. You might need to go through your Dell's setup to make sure that it's recognizing a DVI input rather then HDMI.
Might be a bad DVI cable or a defective monitor or maybe a bad Mini DisplayPort to DVI adapter. Are they all new products?

Second IPS display via hdmi not displaying 2560x1440. Why?

I know the graphic card hardware in my 2013 i7 mac mini support hi-res hdmi because people are running Windows 7 on their mini's with dual 2560x1440 ips displays. I read that this would be resolved in Mavericks but I can't seem to get above the 1080p resolution. What am I missing? Do I need to reset something? Was I better off sticking with my old 2009 mac mini with the mini display and thunderbolt port?
Thanks
Andre

I've received several different answer regarding your reply. The monitor tech support person stated that the hdmi port on the display is 1.3b which will support that resolution. So either both of the hdmi cable that I tried sucked or the support person lied and or OSX is limiting the hdmi port.
I guess I'll just purchase a Startech USB32DPPRO adapter since I can't get the answer I want.
I hate that Apple took away the second mini/thunderbolt port.
Thanks for your assistance.

G4 Quicksilver not recognising second 20" display - Any ideas?

I have just acquired a second 20" Apple Display (plastic version) to run alongside my current 20". Because my G4 has only one ADC connector I have bought a DVI to ADC adaptor to plug into the G4's DVI connector. However when I start up the second screen just isn't recognised.
Does anyone have any idea what the problem might be?
I have checked both monitors separately and they are fine. I have also connected a non-Apple display via the DVI connector and it works fine. Could it be a dud adaptor or have I been the dud and bought the wrong adaptor?
Any help would be really appreciated.
Many thanks

Hi Malcom
Thanks for the reply
Yes I've tried swapping the monitors and neither will work through the DVI to ADC adaptor and all the cables are connected. I guess I must have either bought the wrong adaptor or the adpator is broken. Is there anyway you might be able to tell me if I have bought the wrong adaptor?
Thanks

MBPro won't detect external display on DVI

Hi Folks,
I have a strange problem that gives me quite some headache:
Is use a MacBook Pro 3,1 2.2 Ghz, 4GB RAM, 128MB NVidia something together with a Samsung SyncMaster 215TW.
For the past year I was using my external screen without any trouble, connecting it via DVI to the mac. Every night I turn down the lid putting the notebook in sleep mode and switch off the monitor. Exactly as I did yesterday. But this morning however the external display didn't wake up as usual it did just nothing - was not even detected via the detect display function. And this is still the case right now.
So when I plug (or unplug) the DVI to the external something is still going on. I get the blue screen (don't get that wrong that used to appear just before it would expand the desktop to the external screen, but then it switches back as if there would be nothing connected.
No relevant entries in any logfile. System Profiler shows "Status: No display connected". The display itself says some no connection message if unplugged and - get this - falls to sleep mode right after I plugin the dvi connector to the mac.
I tried all this:
-reboot (with display connected & without display connected and all other imaginable combinations) - no positive result
-the display via DVI-VGA adapter works (but the image is not as nice unfortunately)
-reset PRAM (boot with optioncommand+PR)
-reset the entire thing (no power, no battery and hold the powerkey for 10 secs.) nothing
-connect some other external display to the mac via DVI - works perfectly
-connect the display via DVI to an other macbook pro computer - works perfectly too
-hard reset the display via the (red) support menu - no result
-an other DVI cable - no result
-booted from the leopard install cd - same thing
-booted from an other harddisk with 10.4.10 (removing the internal disk)- same strange behaviour with the old system
-booted ubuntu linux 8.04 - even here the same problem X doesn't recognize the external display if it is attached to the DVI port also no entries to the logs here.
-SwitchResX and tried to reset the display setting from there (vendor id 4c2d & product id 213 & 214) but still no success.
- called the apple support and my distributer of trust - no ideas but could be a hardware fault (mmh ok... but why do all other display I tried work perfectly with that beast of macbook pro but not any SyncMaster 215TW?!? that worked great for the whole last year)
I guess the macbook had a very bad dream that very last night about mac eating foo-bars that crawl through DVI cables from any 215TW display.
As for now I have a date with the local apple service partner -- in three weeks (it's holiday time in g.o. germany). Don't know what to tell him: Probably I'll need to go there with the screen to show them the entire scenario. Hopefully they (still) think it's a problem with faulty apple hardware (or system software) and replace the logic board.
But I'm still in hope! Is there anybody out there having an idea with what I could try next to bring back the love between my macbook and the lovely 215TW display?
greetings,
brutus banane

I have recently bough a new Macbook Pro 15.4", it worked first time with a Samsung Syncmaster 2493HM but after a few days the 'detect display' utility ceased to connect, then a short while after on start up I was getting a blank screen with a flashing folder with '?' on it, preventing me from booting up successfully.
I tried the reset p-ram, didn't work then I tried an archive install of OSX and that ironed out all the creases - for a day, there has been no flashing folders on start up but the Samsung has failed to be detected and this morning wouldn't work no matter how many restarts or cable disconnecting attempts.
So I called Apple helpline, told the guy what had happened, he mentioned to try the install discs again with the display connected to see of the MBP sent a signal to it, after choosing the language in the OSX installer, the display was once again recognized! I didn't have to proceed any further with the install discs so quit, reset and ejected the install discs and all seems well again.
For how long i wonder?
I have no idea of this will work for anyone else but it works for me at the moment.
Interested to see when and how this finally gets solved!
T.

Macbook Pro won't connect via DVI

Hello all,
My Macbook Pro suddenly won't connect to any monitor using a DVI connection. If I use a VGA monitor (via my DVI to VGA connector), everything is dandy, but connecting directly to a (i.e.) Samsung or an Apple Monitor via DVI, the OS just blinks once (like if there is a connection), but the display is not being detected and is not turned on. I tried to delete all display preferences and I've zapped the PRAM without any result.
Before I send the powerbook in for repair (my fear is that it's the DVI-connector that's broken), I just wanted to see if there's anybody out there who have had similar problems, that perhaps could be solved via software (i.e. the system)...
Cheers,
Massimo

I am having the same problem as the rest on this thread. My VGA works fine in most cases, but my DVI will not work with any amount of prodding. Also, I have been trying to make use of matrox dualhead2go's and triplehead2go's, but these will not function correctly unfortunately. I got the whole logic board replaced a year after I got this laptop because it had strange display issues (the old red/blue square problem) but I'm far out of warranty now.
I am a student and a video artist requiring use of multiple projectors for my final mfa thesis project..but this is really going to mess up my plans if there isn't a free/cheap fix..anyone have suggestions for speaking with tech support/customer relations?

Using second display via eMac's mini-DVI to VGA adaptor

Hi,
I've got a 19inch widescreen display from Acer, model no. AL1916W. I have apple's mini-DVI to VGA adaptor and have connected the second display to the point where it mirrors the screen on my eMac, however I don't want it to do this.
What I had intended is that the second display would act as an extension of my eMacs screen, so I can drag windows across for extra space. Is this possible with the eMac?
Put more specifically, I want to be able to put logic's main (arrange) window on the Acer widescreen, and then have whatever else on the eMacs screen? Is there a workaround to do this?
help much appreciated,
Toby

Hi,
It's funny you should send me that link, I actually found that a couple of hours after posting this and tried it. It worked perfectly, I now have the widescreen running in it's native resolution and working as a separate screen which I can drag stuff in and out of. I came back on here to mark the question as 'answered' but I couldn't find how.
thanks for your help,
Toby

Apple 20" CD connects fine to MacBook Pro 2009 via DVI to Mini displayport (adapter) but not to Radeon 5770 (either MDP ports) on MacPro 2008?! Have Eizo CG223 on DVI to 5770. Any ideas?

Here's the setup:
Eizo Coloredge CG223 DVI to DVI on MacPro 5770 interface (ACD works fine on this too, naturally).
Apple Cinema Display 20" have the DVI connector. I have a Mini Displayport to DVI adapter on this, into one of the 5770's MDPs, neither of which seem to work.
Plug the same ACD via DVI (with DVI to MDP adpater) into my MacBook Pro 2009 MDP and it works fine as a second screen.
So what's up with the 5770 MDPs? I've seen online that the card should at least support two displays, either MDPs x2 or MDP and DVI. I've seen there may be an issue with three, not two.
Any ideas please?
Thanks,
Y

MBP to an a/v receiver via dvi to hdmi cable, display not detected?

So as the title says, I'm trying to connect my MBP to a Sony str-dg510 a/v receiver in this order:
MBP >
Mini Displayport to dvi connector (http://store.apple.com/us/product/MB570Z/A?fnode=MTY1NDA5OQ&mco=MTA4ODk2OTE ) >
dvi to hdmi cable (http://www.amazon.com/DVI-HDMI-Cable-6ft-Male-Male/dp/B0002CZHN6 ) >
Sony STR-dg510 AV Receiver >
Analog TV.
And here's the issue: I'm not getting a second display detected at all. It is an analog connection from the AV receiver to the TV, and I've connected other laptops to the receiver just fine, albeit on a different input.
So I'm not sure where to go from here, the mini displayport to dvi works fine onto an apple display at work.
I also got an unlock message on the receiver at first and thought this may be the issue, so I got an optical audio cable similar to this: (http://www.ramelectronics.net/audio-video/audio-cables/digital-audio-optical-tos link-cable/poft3ps/prodPOFT3PS.html )
And now the sound plays fine, but still no picture (and the unlock message is gone.)
Any idea's?
Thanks

Welcome to the Apple Community Q62.
If it works fine on another TV but not directly with this TV, the problem is with your TV or your cables. Have you eliminated the cables.

PB Al 15" won't display to Dell 2001FP via DVI

After hooking up a Dell 2001FP display to my PowerBook Al 1.5Ghz/15" via DVI, the external display displays nothing. The Mac senses the display per Monitors system preference and Apple System Profiler but nothing is output to the display. I'm using Dell's bundled DVI cable (which appears to be a DVI-D single link, per http://www.comsol.com.au/dvi.asp). DVI works just fine via PB G4 1.5Ghz/12".
As a workaround, the VGA is working fine from the PowerBook to this display. I'd really, really much rather use DVI. Is there any way to get this PB Al 15" to work via DVI to the Dell 2001FP? Possibly via some different kind of cable?
Scanning the Apple forums didn't get me a direct answer. I vaguely remember something unique about the 15" DVI with certain third party configurations.

Try resetting your NVRAM…
http://docs.info.apple.com/article.html?artnum=2238
Another thing to try is to change the ends of the DVI-D cable. I too am using the included cable that came with my Dell display and it works just dandy. Obviously if it works with your 12" PowerBook then the problem is with the 15" PowerBook.
It is possible that the 15" is trying to display at a setting that your display can't handle. What you can do is to open the Displays System Preference, click on the Gather Displays button and try different settings. Make sure you start at a 60Hz refresh rate.
To be honest it's a bit weird that you're having a problem because it, as I'm sure you're aware, should just work.

Imac 27" Intel Core 7 CPU. Screen goes black and will not respond except with a push of power button. Second monitor connected via displayport continues to display fine. Apply Store did full hardware scan and all is fine. Did clean wipe from Mavrick back

Imac 27" Intel Core7 CPU 16 Gig RAM. Screen goes black and will not respond except with a push of power button. Second monitor connected via displayport continues to display fine. Apply Store did full hardware diagnostic and all is fine. Did clean wipe from Mavrick back to Mountain Lion but problem remains. Apple Store can do no more.

I did some more digging, it appears to be a backlight problem only. I can see the screen very dimly if I use a bright flashlight in a very dark room. It also seems to run ok if the brightness is turned down a LOT.
So I'm thinking this is a LED driver board issue or the display itself. I'll open it up and check the connection between the two and see if I can get any more clues. At least I can use it somewhat now by dimming the display significantly...

New Apple Displays DVI Connnection Type

Does anyone know what DVI connection type are the new Apple displays equipped with? I know that it recieves digital signals, but can it recieve analog signals too? In other words, is the DVI connector DVI-D or DVI-I on the new displays?

Hi Ethan,
I'm not sure I understand exactly what you want to do, so I'll try another approach (hope it helps this time :))
A DVI-I socket (off the graphics card) provides digital and analogue output. The DVI-I plugs off the DVI Apple Displays (except the 30") physically fit this socket, but don't utilise any of the analogue output. These DVI-I plugs will also plug into a DVI-D socket.
A DVD-D socket provides digital output only. The DVD-D plugs that the 30" Apple Displays use will only fit this socket and will not connect properly to a DVI-I socket.
There are very few Mac graphics cards around at the moment that have the required DVI-D socket for the 30" Apple Display. The majority of them are Apple OEM.
You said:
"Like I was saying if it has a DVI-I input, it can receive analog signals using a VGA to DVI adapter."
Because it is going through an adaptor, it is not receiving analogue signals (as these signals have already been converted to digital). A VGA to DVI adaptor is a little complicated, with a hardware based translation of the analogue signal to digital being required - this can result in some loss of signal quality. This is why it (physically) is a box with an input cable and plug and an output cable and socket.
However, a DVI-I to VGA adaptor is much easier (because of the analogue component in DVI-I that you have mentioned). All this adaptor does is to pick up the analogue signal already there and ignore the rest. This is why it (physically) is just a cable with a DVI-I plug at one end and a VGA socket at the other end. These adaptors will not work with DVI-D sockets.
Some (non-Apple) LCD displays accept both digital and analogue input, but they do this through separate DVI-I and VGA plugs. When using VGA input, they utilise an internal converter to translate the analogue signal to digital. An LCD display has an absolute requirement that the video input that it eventually processes is digital. Only CRT monitors really use analogue.
If you want to use a 30" Apple Display, you need DVI-D output. If you want to use any of the other Apple DVI Displays, you can use DVI-I, DVI-D or DVI-I via a VGA to DVI-I adaptor.
Hope this is what you were after!
Cheers!

TV & monitor connected via DVI to VGA & DVI cable. Wont display

I have my TV & monitor connected to my mini via DVI(input) to> VGA(output) & DVI(output) splitter cable. I cant get both tv and monitor to work at the same time only one or the other. How can I get this to work?
Note: I dont want a continuous display, I just want one to show the same as the other. If there both plugged in why dont they both work?

The answer to your question would require having a block diagram of the mini's graphics sub-system. If the DAC (digital-to-analog converter) behind the VGA port is just driven from the same output as the TMDS transmitter behind the DVI port, then I agree it would be possible that both could output the same screen simultaneously. But if the VGA and DVI ports are treated as seperate channels all the way back to video memory, then likely one would be prioritized over the other, only one could be active, and they would not be able to output simultaneously.
Another potential problem is that TVs and computer monitors generally want to run at very different formats and they require different signal types to be happy. A TV will want an interlaced output whereas a computer monitor will not. And a TV will want a very low resolution, like 640 x 480, whereas a computer monitor will be happiest at a much higer resolution.
I hope for you that someone else has this working and chimes in with some practical advice. I try to avoid making posts where I have no practical advice to offer and only bad news, but in this case I thought you might want to know about some potential barriers to success. Good luck.

Cannot get iPad 2 charged beyond 1%. All charging ports tried: AC adapter(s), USB 2 port on MacBook Pro. ITunes shows iPad only for a few seconds. iPad displays alternately: Apple logo, battery w/slim red band, then battery w/1% charged information. How can I get it to charge beyond 1% so I can proceed to troubleshoot?

I have had your exact problem with my old 3GS, now I cannot even get it to turn on, I still see that it is supposed to be charging though, but it never charges any so it seems.
I replaced the Lower Dock Connector Assembly back when it still charged while hooked to my PC, and it found it made no real difference.

At this point I am not sure if I should replace the battery and hope for the best, or just junk the phone, I cannot really sell it if I cannot reset it...
