Dynadock U3: no signal on DVI port

Hi,
I run a Dynadock U3 (PA3927E-1PRP) on a Dell XPS-12 under Win8.
The configuration worked fine for a number of weeks, now a strange behaviour appears from time to time: the DVI monitor (LG-20D) is recognized by windows (it switches to split screen, the USB sound is played) but the monitor has no signal.
Different manouvers help from time to time but I so far did not see any reliable strategy:
-Powering off and on of the Dynadock sometimes help
-unplugging of the USB cable could help
I have the latest DisplayLink driver for Win8 installed (7.1M1), deinstallation and reinstallation also did not improve anything.
I would appreciate any helpful comment.
Best regards
TimTom
PS: is there any tool to review the dynadock status around?

Well you have tried going back to the old version and reflashing so perhaps co-incendence?
Might want to open a ticket with msi.
>>How to contact MSI.<<
At the same time, re-seat the CPU, check under the main board and the rear i/o shield for shorts and reseat the other components. Although it seems the bios flash has done something odd.
I'll also link this to Svet and see if he has any ideas, but this is weird.

ATI X800XT is adc port same dvi signal as the dvi port

For starters, what does "adc" stand for? Does it mean the adc is an analog port needing conversion to digital for display to an apple cinema display? someone at apple just said it stands for apple display connection. Yes, I know I still need an adapter, but I'm wondering if this port is inferior the the dvi port on the card. I don't know if the adaptor is just changing the physical hardware connections, or something else.
I want to go from the adc port thru an adc/dvi adaptor to the matrox mxo box, out of the mxo to apple hd 23" display. I need to reserve the other graphics port (dvi) to go thru a dvi/vga adaptor to my vga monitor.
Is the adc port on the card the same as the dvi port in terms of the type and quality of signal? What is the adc port anyway?

The video quality should not be compromised by using any of these adapters. The ADC outputs the same exact digital signal as the DVI outputs. The ADC-to-DVI adapter basically discards the USB and power features and passes the digital AND analog signals through.
As mentioned above, both ADC and DVI also carry analog video signals. Using a DVI-to-VGA adapter, an ADC-to-VGA adapter, or a combination of both will allow you to use an analog VGA monitor from either port on your video card, again with no degradation of the signal.
If you are missing any or all colors or the signal is degraded in some way, you must have a bad connection, bad adapter, or bad cable. Try reconnecting or replacing each part one at at time to determine the culprit.
As for the problem of non-matching DVI connectors, check the link below to determine which ones you have and which ones you need. There are pictures of each connector on this page:
http://en.wikipedia.org/wiki/DigitalVisualInterface
http://en.wikipedia.org/wiki/AppleDisplayConnector
You should be able to find an adapter (or gender changer) that matches up to your cable. A web search should give you plenty of sources and options. You may try a place like Cyberguys.com: http://www.cyberguys.com/ (Search for "DVI gender" to see all available adapters.)
With quality cables and adapters, you should be able to achieve what you are trying to do with no signal degradation to each of your monitors. Let me know how it goes.

Mini-DVI port not working: wear and tear?

I had been happily using the mini-DVI port to play content on TV, using a DVI to Video adapter : plugging and unplugging probably twice a week.
Now it seems to have stopped, abruptly: no signal at all is reaching the TV. (Adapter still works fine on my MacBook.)
What are the chances of wear and tear damaging the DVI port? Is this a complicated fix? Any other thoughts? No recent upgrades or updates.
"About this Mac" reckons it's mirroring fine, so it feels like a hardware thing. Many thanks in advance.

Hello ewfelton
It is very possible that the DVI port on the iMac has been damaged from wear and tear, as it's harder to get at than the MacBook.
I would disconnect everything from the iMac, grab a clean towel and turn it face down on the desk. Then with a magnifying glass and light inspect the DVI port for a broken or bent pin. In the process of inspecting the port your SMC will also be reset, follow the instruction for "How to reset the System Management Controller" when your done.
If the port seems OK and the SMC reset doesn't get it going use Disk Utility to Repair Disk Premissions and try it again.
Your local Apple Store or local Apple Service Provider can replace a bad or damaged DVI port.

New Macbook Pro, no mini-DVI port? (HDTV connect question)

Most online resources suggest that Mac users can connect their computers to their HDTV's through the mini-DVI port, but I examined my Macbook and saw that the new version (purchased 2 months ago, roughly) doesn't have this port. This being the case, what can I use to connect my laptop to an HDMI cable? Thanks in advance for any and all help!

MacBook Pros now have a "Thunderbolt" port that is supposed to be backwards compatible with Mini DisplayPort (not Mini-DVI they've used the Mini DisplayPort since 2008) and, likewise, supports an external display at 2560x1600 and passes an audio signal.
http://store.apple.com/us/product/H1824ZM/A?mco=MTY3ODQ5OTY

I cannot use any external monitor, it appear like the port doesn't work , i'm using the mini-dvi port with a VGA adaptor ,

I've always used the port normally with different monitor but by a couple of weeks it appear like no signal come out.
Does Anyone knows what can i do ? i.e. How to check or reset the Mini-dvi port ? or if there's any key on the keyboard that can habilitate it or not ?
Any Help will be appreciate
Thanks

Welcome to Apple Support Communities
You don't have to do anything to make the port work. Reset the SMC > http://support.apple.com/kb/HT3964
If it doesn't work, try with another monitor to see if it works or another cable. If you haven't got another display, take the MacBook Pro to an Apple Store or reseller, so Apple will test the port and see if it works correctly

"No Signal" from DVI on Viewsonic VA912b display

I'm trying to usu the DVI port on my Dual 1.8 G5 (10.3.9), but all I get is a few seconds of the Apple boot screen and then I lose the signal. My display works fine with the VGA adapter, but I'd prefer to use the DVI if possible.
Any and all help would be greatly appreciated.
Namaste.
Dual G5 1.8 Mac OS X (10.3.9) ViewSonic VA912b display

VGA and DVI are managed by the OS as two completely different interfaces. When you switched the VGA setting to 1024 x 768, that has no bearing on what the DVI port outputs. So when you swapped the interface from VGA to DVI to the monitor, the Mac was outputting the same (invalid) resolution as before and not 1024 x 768.
Are you really running 10.3.9 as in your sig, or are you running Tiger? There is a way to switch resolutions using the keyboard without benefit of a useable screen under Tiger. Or you could also establish a VNC connection to a second computer on your network and change the resolution on your G5 using the VNC client.

Possible to use the MBP display for use with XBOX 360 through DVI port?

Hi everyone, I know that the topic sounds ludicrous to probably a lot of you. After all, how dare a Mac user use a Microsoft machine right ;)? Well, truth be told, I like the 360 and that's the only MS product I prefer to use.
Anyway, I'm going to be picking up my own 360 within the next few days and am currently deciding whether to also buy a new HDTV with the purchase or if I can wait. I'm going to be buying a new TV eventually but I was hoping to put off the purchase for a while since I remembered that the 360 can hook up to monitors through VGA. So what I want to know is whether the DVI port on my MBP is output only or will it accept input signals? Also, if it is possible to hook up my 360 through the DVI port, is there an easy way to attach the DVI-VGA adapter to the 360 seeing? By this I mean, the adapter is only about three inches or so and it would be pretty difficult to attach both machines to each other, so I was wondering if there might be a female-female VGA adapter bridge or some easy method of doing this.
Thank you all for your help in advance.

Outsider,
Check out this link and enjoy the 360 on your MBP!

Need to connect an Apple Display with an ADC plug to a Mac Mini with a DVI port

I have an older Mac Mini (I'd guess at least 4-5 years old, but I have a terrible memory), and I want to connect a Cinema HD Display with an ADC connector plug. Unfortunately, my Mini only has a DVI port, and I cannot find an Apple adapter, or any adapter for that matter, under 200 dollars, which is an absurd price to simply connect one slightly different plug to another. If a $200 adapter is really the only option, then I will find a different monitor, but I would prefer to connect this one, as it is the most convenient option.

It is far more than a matter of different plugs. The signalling schemes are completely different and it also has to act as an external power supply for the screen. This screen was originally designed to get power from a PowerMac computer.
I found a genuine adapter on Amazon see http://www.amazon.com/Apple-M8661LL-Display-Adapter-4038234011420/dp/B00011KHT2 at $119 but other than that you could look on eBay for a used one.
You are right to consider whether it is worth paying more for a brand new screen rather than trying to extend the life of this old screen. Be aware that if you want to try using Apple's latest 27" ThunderBolt screen you cannot directly connect that to your old Mac mini but could do so by (you guessed it) buying another expensive adapter. In this case you would need an adapter from Kanex see http://www.kanexlive.com/c247dl
You can of course use virtually any standard (non Apple) DVI display.

Ref GTX 680 2nd DVI port stopped working

I'm having trouble with my GTX 680 second DVI port. It seems to register that it's connected, but doesn't have any signal.
Now, it's worked perfectly for weeks... until I replugged it yesterday.
My set-up (that used to work):
>DVI port 1 goes to main monitor
>DVI port 2 goes to second monitor
>HDMI port clones DVI port 2 and goes to TV
And this is what I did:
>Unplug 2nd DVI port, use it temporarily for another machine
>Replug hours later, not working
And what I've tried:
>rebooting
>reseating the GPU
>blowing dust out of the GPU
>emptying my computer for power (pull out powerplug, hold power button for 30 seconds)
>clearing CMOS
>different drivers (both with and without clean install option)
>plugging monitors into 2nd DVI port (no signal from any monitors)
>tried DVI to DVI, DVI to VGA, and DVI to HDMI - nothing seems to work
>tried older GPU, it worked (with both ports)
>tried the onboard DVI port for 2nd monitor, works but then I can't "clone" it to my TV.
It also doesn't seem to get any signal during POST and BOOT (tried both monitors).
The monitor also appears in "Screen Resolution" but as "Available display output: on Intel(R) HD Graphics 3000," but it doesn't work.
When I messed around with it, trying to get it work, it also had an option to "force VGA" or something like that - but that did not work either.
Specs:
>ASRock Extreme3 Gen3
>2500K
>8gb Samsung Green low profile ram
>MSI GTX680 with ref cooler and EVGA backplate
>Corsair AX750
>OS: Windows 8 x64 (although I doubt the operating system is an issue, since I don't even get output during POST/boot).
I've tried searching, but to no avail. I've found people with similar issues, but none that managed to solve it. Example:

I'd RMA the card as it sounds like the 2nd connector is broken and is not working guess it wasnt soldiered in place properly and its cane away on one of the connectors!!
Sounds probable, but if you look at the first link I posted where other's have similar issues (https://forum-en.msi.com/index.php?topic=142971.msg1066807#msg1066807) he tried swapping his GPU and it did not work for him. It might of course still be that the connection is just bad on my GPU and something else for him.
I'll wait a while and see if other's can come up with some good suggestions. If not, I guess I have to RMA it.

Running two displays from one DVI port...time to put my ADC down

Hi Guys,
I have a G5 dual with a GeForce FX 5200 which has 1 each of DVI+ADC ports. Until recently the 17" Apple display has been my only monitor. As I have a recording/mix studio I need to move the G5 base unit far away from any recording as it makes quite a lot of noise. I have been unable to do this as I have been having trouble finding either a Dr Bott or Griffin ADC extension. I have been searching off and on for over a year with no success.
Recently I purchased a cheap reconditioned NEC monitor which I am running from the DVI port and am thinking perhaps now is the time to get rid of my apple display due to the ADC connection troubles.
Is it possible to run two monitors from the one DVI port? I need to run a mirrored image so that I have one monitor to my side so that I can do close editing work and then one further away behind my analogue mixing desk, they need to show exactly the same thing.
Will splitting the DVI port degrade signal or is there a way around this. I also want to get some long cables 6m+ so that I can place the base unit outside of the control room, will this be a problem?
I would really appreciate some help on this matter.
Thanks,
Iwan

Thanks BSteely, Would you happen to know of a box to recommend? I guess something like this would be more suitable:

Z97M GAMING no hdmi signal with DVI converter

My monitor has VGA/DVI only (Samsung SyncMaster 213T), I have a HDMI to DVI converter in the DVI port, this works with the HDMI out from my laptop.
Am putting together a Z97M/4790K rig. I get no signal at the monitor from the Z97M's HDMI out, if I connect it to a TV I do get a signal.
Am using the same (short) HDMI cable and adaptor with both the laptop and the new Z79M, used the same cable to connect the Z79M to the TV.
So the cable and converter are good (they work with the laptop) and the Z79M HDMI port and cable are good with the TV.
Anyone have any idea why the Z97M HDMI output wont display on my monitor? (Any bios settings to make the HDMI signal more compatable?)

Yes, to be clear, there is no GPU. When I say the Z97M's HDMI out I mean the output from the Z97M motherboard. I have tried it with a second screen, the TV (it worked).
Logically one of two things must be happening... either the Z97M's HDMI signal isn't making it through the DVI/HDMI adaptor (when the laptop's signal is), or the monitor cannot process the Z97M's HDMI signal (when it can process the laptop's).
HDMI and DVI signals are the same, so the adaptor is just a plug converter ('square plug in round hole') and unlikely to be the issue, especially as it works with the laptop.
But both the monitor and laptop (which work together with HDMI and the DVI converter) are >5 years old. The Z97M is very new and could be it's HDMI output just isn't compatable in some way with the (relatively) old monitor.
Hence am wondering (for example) if there are any Z97M bios settings which might make it talk nicely to the old monitor.
Be interested to hear if anyone has had issues (or even success!) using the HDMI out with DVI monitors, especially old Samsung SyncMasters ?

livnsa, Have you got a DVI cable hooked to the DVI port and getting no output? If you have a DVI adapter on the VGA port this won't work. Also just the monitor hooked up or do you have a TV too?

Adding a DVI port onto my Imac

I want to to display another computer onto my imac. It only has a mini dvi out. Is there a way to install a dvi in port??

jessylee13 wrote:

For all practical purposes, NO.
The LCD panel is driven by LVDS signals, while DVI uses TMDS signals.
So, you'd have to add TMDS receiver chips and LVDS driver chips, plus
whatever logic might be required to convert from one to the other. The
conversion is non-trivial; a monitor is much more than an LCD panel.
You'd also have to add video switching to select between internal and
external sources.

Can a Macbook send audio via DVI port?

I want to hook up a Macbook to an HDTV by using a mini-DVI to DVI adapter, connected to a cable that has a DVI connection on one end and an HDMI cable on the other.
Does anyone know if the min-DVI port supports audio?
The more expensive cable supports audio, but I don't want to shell out the extra money if the Macbook can't support it.

DVI does not carry an audio signal. It takes HDMI to do that. You'll need to use a separate audio cable.

Problem connecting 2nd PC to DVI port on a L171p

I have an IBM Thinkpad T60 plugged to a docking station and connected to my LCD via VGA connection. I want to connect a second workstation via the DVI port. I got an adapter to connect my DVI cable to my VGA on the 2nd system (Lenovo ThinkCentre) port but no joy.
Can anyone help???

You have to make sure that it is the right kind of adapter. DVI to VGA is different in that you have to make sure you get the right cable or adapter that will transmit the analog version of the DVI signal. If you got the adapter that transmits the digital signal of DVI, then the connection will not convert into VGA, as VGA only accepts/transmits an analog signal.
This site might help explain it better: http://www.datapro.net/techinfo/dvi_info.html
Hope this helps...
