DVI cable not working, but VGA one will. Graphics card problem?

Ok so. I have a Mac Pro with ATi 1900XT card. Was using a Samsung LCD for a while, via a DVI-VGA adapter. Works fine. Two days ago, I attached another monitor, a DGM, to the second DVI port using a DVI lead; the one supplied with the monitor. Everything worked fine.
Then today, I tried the same thing, but the second monitor only works at one particular resolution; 1280x800 or something. And the picture is a bit crappy. So, I tried with only the DGM monitor plugged in the first DVI port. Apple symbol at start up, and then just a black screen.
Swapped over to a VGA lead, and everything works perfectly again.
So, is the problem with the cable, the monitor, or the graphics card?
Maybe the cheapo cable is just not very good? But why it works only at one resolution? Weird. And it did flicker on at a couple of other resolutions, but went off again. And even at the one resolution it worked at, there was a secondary 'mirror' image of part of the screen, at one side of the screen.
Very strange, considering it worked perfectly before.
Oh, and I upgraded the Mac Pro's firmware yesterday. Could this have anything to do with things?
Weird...

Forgot to add, we are running XP. We tried a different monitor and now at least we can get one monitor working via the display port. But when we try two monitors at the same time, the 2nd monitor on display port is not detected. How do we disable built in LCD on the X201 ? Lenovo support says its a BIOS setting ? That doesnt sound right to me...
Are you trying to use a DVI Splitter? I do not think that a DVI Splitter would work with a Single Link Displayport TO DVI Adapter. I do not think a Dual Link Displayport To DVI Adapter would work with a DVI Splitter.
I think that you might need something link this.

Not sure, if the x201can handle 3 monitors in this fashion. StarTech.com says the GPU determines the support according to the youtube video.
It is pretty expensive,and it would be nice to know the limit.

Mini-Displayport to DVI adapter not working, but Mini-Displayport to VGA and Thunderbolt work fine

Mini-Displayport to DVI adapter not working, but Mini-Displayport to VGA and Thunderbolt work fine.
This is a brand new MacBook Pro (15-inch, mid-2012) just received. I suspect that this is a hardware problem as:
The mini-displayport to DVI adapter and the external monitor that I am utilizing connect and operate just fine using my older MacBook Pro (mid-2010) with the same OS.
The new MacBook Pro powers the external monitor with a mini-displayport to VGA adapater without issue.
The new MacBook Pro powers an Apple Thunderbolt display without issue.
Both MacBook Pro's are running OSX Lion 10.7.4.
The only combination which does not work is the mini-displayport to DVI adapater used in conjunction with the brand new MacBook Pro (mid-2012).
All adapters and components (mini-displayport adapters) are Apple retail adapter.
I have tried several external monitors, including my Dell U2412m.
When I connect the mini-displayport to DVI adapater to the new MacBook Pro (mid-2012), nothing happens. The external monitor reports "no signal" and attempts to go into sleep mode. Using the "Detect displays" button has no effect, even when used multiple times. Rebooting does not help, nor does resetting the SMC or PRAM.
Any other suggestions before I take it to the Genius Bar?

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.

Wifi Not Working!!! AMD Graphic Card Drivers Not Available as well!!

Hello Everyone, I bought this HP 15-ac025TX (M9V00PA) Notebook laptop and I am having the same problem that others on this forum with this notebook are having i.e. wifi is not working/available and AMD/Intel Switchable High-Definition (HD) Graphics Driver is not available for download. I saw one solved post regarding this problem but the guy had Windows 7 32 bit and also I couldn't understand much that was discussed in that post. Here is the link to that post: http://h30434.www3.hp.com/t5/Wireless-Internet-Home-Networking/Network-controller-amp-USB-controller-driver-not-found-and/td-p/5177717 And yes, I have downloaded all the available drivers on the hp site. Help Needed!!

Hi: These wifi and BT drivers should work... Wifi: ftp://ftp.hp.com/pub/softpaq/sp71501-72000/sp71528.exe Bluetooth: This package contains the Broadcom bluetooth driver and software for supported notebook models that are running a supported operating system. Broadcom Bluetooth 4.0 Driver is required to enable Broadcom bluetooth 4.0 devices and is compatible with Broadcom bluetooth 3.0 and earlier versions. File name: sp71440.exe I reported the graphics driver problem to HP a couple of weeks ago. I hope they get that sorted out soon!

DVI not working but VGA is on 7300GT on Mac Pro

I ran into an odd issue where upon starting up Mac Pro, my second 7300 GT Card was not outputting video to monitors 2 & 3. They were connected to my 2 ViewSonic 2025 LCD's. The stock video card worked fine. I powered down the Mac and still no joy after resetting PRAM and re-seating the card. Next I tried using DVI to VGA adapter and plugging into the ViewSonics VGA ports and this worked fine. I'm stumped-any ideas? Could it be the displays? If so, it seems odd that both LCD's would do it at the same time.

You say monitors two and three, do you have two video cards or are you splitting a signal?

New ipods not working, but old ones do?

Here is the situation:
New 2G nano won't mount with toshiba laptop (satellite a105) running xp home.
Will mount elsewhere on other computers running xp home and pro.
5G ipods and 1G nanos mount fine.
itunes 7.0.1
tried every usb port.
here's the interesting part... my 80gig ipod won't mount either. must be something with the new firmware/hardware.
Any ideas as to why this might be happening? solutions hopefully less drastic than a reinstall of windows or sending ipod back?

Ok How old is the laptop? After looking at the Toshiba website it looks like it has USB 2.0 ports. But if yours is an older issue it might be a problem.
The only other thing I can suggest is updating all of the Laptop's drivers. http://www.csd.toshiba.com/cgi-bin/tais/su/suscmodItemList.jsp
When punching in IPOD in the toshiba's website searchbox. This comes up as a possible Match. http://askiris.toshiba.com/ToshibaSupportSite/search.do?cmd=displayKC&docType=kc &externalId=1504530xml&sliceId=&dialogID=7371741&stateId=0%200%207369702
Looks like a Bios Update is in order.

My trackpad will sometimes not work but external mice will.

I have the newest version of Macbook Pro. It is all up to date. Sometimes, the trackpad will arbirtarily stop working for a long period of time. However, when I plug in an external mouse, the cursor moves and selects normally. Is this normal? How can I fix it?

Erratic trackpad?

TS2634 why will my charging cable not work on my ipad?

Why will my charging cable not work on my ipad?

Try giving your iPad a reset. Hold down the sleep and home keys for about 20 seconds. WHen you see the silver apple, let go and let it reboot then try again.
Try unplugging/replugging the cable. I can't tell if you have a lightning or older 30 pin cable, but if you have the 30 pin one it can look like it's in but not be making a total connection.
Look in the port, do you see any dust or lint? THat can mess with the connection.
Are you trying to charge via USB or plugged into the wall? It's best charged plugged into the wall with its supplied power block.

Don't freak out, just get over it. It's probably done.
